114-506: Callowhill was formerly home to large-scale manufacturing and other industries, of which an architectural history has been left in the form of grand old abandoned factories. During the 1970s and 1980s, the population of Callowhill plummeted, and although numbers are rising, it is a fairly unpopulated section of the city compared to surrounding neighborhoods. Recently developers have started to employ adaptive reuse projects, converting them into loft style housing ; so much so that many have termed

228-404: A "predicted useful life" of a building by considering a series of physical, economic, functional, technological, social, legal and political characteristics. These characteristics are used to derive an "annual obsolescence rate" and "environmental obsolescence". These outcomes are necessary to determine an optimum point at which adaptive reuse intervention should occur. Obsolescence is advanced as

342-478: A BAS to automatically update the plaque, providing a near-real-time view of performance. The USGBC office in Washington, D.C. is one of the first buildings to feature the live-updating LEED Dynamic Plaque. Industries use a large amount of energy to power a diverse range of manufacturing and resource extraction processes. Many industrial processes require large amounts of heat and mechanical power, most of which

456-432: A brand-new building in its place can lead to high energy requirement for the demolition, building material waste management, new material procurement, construction and operation. On the other hand, sustainably retrofitting an existing built asset only requires a fraction of this energy. It is important to keep in mind that many of the old building may not have the best of operational energy use efficiency. Therefore, to achieve

570-418: A budget is prepared. Building owners or developers can approach any of the financing sources such as insurance companies, foundations and funds, savings banks, building loan societies, endowment funds, Real Estate Investment Trusts, etc. In most adaptive reuse projects, it is the architect who is the leader with the imagination of how an abandoned warehouse can become an office building or an abandoned hospital

684-464: A building can reduce the need for artificial lighting. Increased use of natural and task lighting has been shown by one study to increase productivity in schools and offices. Compact fluorescent lamps use two-thirds less energy and may last 6 to 10 times longer than incandescent light bulbs . Newer fluorescent lights produce a natural light, and in most applications they are cost effective, despite their higher initial cost, with payback periods as low as

798-430: A building must first make sure that the finished product will serve the need of the market, that it will be completely useful for its new purpose, and that it will be competitively priced. Adaptive reuse is defined as the aesthetic process that adapts buildings for new uses while retaining their historic features. Using an adaptive reuse model can prolong a building's life, from cradle-to-grave, by retaining all or most of

912-477: A building should be conserved and remodeled for a different use or just demolished for the land it sits on, then develop a new building on that land. These decisions are governed by the following criteria: The decision to reuse or demolish built assets is driven by economic considerations such as development costs, project costs, investment returns and market. The economic costs differ from project to project and some professionals go as far as to assert that "new build

1026-555: A building's compliance with the following criteria: Sustainable sites , water efficiency , energy and atmosphere, materials and resources, indoor environmental quality, and innovation in design. In 2013, USGBC developed the LEED Dynamic Plaque, a tool to track building performance against LEED metrics and a potential path to recertification. The following year, the council collaborated with Honeywell to pull data on energy and water use, as well as indoor air quality from

1140-435: A collaborative approach, will allow stakeholders with diverse interests regarding adaptive reuse to come together and participate either directly or indirectly in any stage of the decision-making process. There are four typical categories of stakeholders involved in an adaptive reuse decision-making process: i) investors; ii) producers; iii) regulators; and iv) users. Identification of Parameters: identified parameters for

1254-473: A commitment to sustainability and urban regeneration". However, this solution has several harmful implications and forcing an adaptive reuse directive on to the industry and its clients was deemed to be heavy handed and could be counterproductive. The existing building codes and regulations for fire safety and building access to disabled make it difficult to work around the adaptive reuse of old constructed buildings. In this civilized world, buildings have become

1368-436: A condominium. Since the architect has a deep involvement in the success of a project, he must perform his work under a clearly defined contract. Under this contract, the architect and the owner are under the obligation of the contract and must abide by it. Progress of design, site visits and evaluation are some of the basic actions that the architect performs under this contract. There are different types of contracts, ranging from

1482-428: A constant speed, but a variable speed drive allows the motor's energy output to match the required load. This achieves energy savings ranging from 3 to 60 percent, depending on how the motor is used. Motor coils made of superconducting materials can also reduce energy losses. Motors may also benefit from voltage optimization . Industry uses a large number of pumps and compressors of all shapes and sizes and in

1596-453: A cost vs benefits analysis is essential to determine the return on investment of an adaptive reuse project. The most important governing factors of adaptive reuse decision making with respect to asset condition were observed to be the building's structural integrity, its residual service life, its spatial layout, its location and the ease of retrofitting or installing new building components to the existing built form. According to Bullen and Love,

1710-418: A documented methodology for calculating and reporting on energy savings and energy efficiency for countries and cities. The first EU-wide energy efficiency target was set in 1998. Member states agreed to improve energy efficiency by 1 percent a year over twelve years. In addition, legislation about products, industry, transport and buildings has contributed to a general energy efficiency framework. More effort

1824-534: A few months. LED lamps use only about 10% of the energy an incandescent lamp requires. Leadership in Energy and Environmental Design (LEED) is a rating system organized by the US Green Building Council (USGBC) to promote environmental responsibility in building design. They currently offer four levels of certification for existing buildings (LEED-EBOM) and new construction (LEED-NC) based on

1938-446: A fixed fee contract, percentage of construction cost contract and fee plus expenses contract. All stakeholders may collectively decide on the most suitable type of contract for the project. Before the architect and engineer begin the final designing for the building, they make a thorough structural, mechanical and architectural survey of the existing building. The architect and engineer may look for signs of cracking of masonry wall or

2052-597: A flexible energy tax which rises as petrol prices fall, thereby incentivizing fuel conservation despite low oil prices. In Spain, four out of every five buildings use more energy than they should. They are either inadequately insulated or consume energy inefficiently. The Unión de Créditos Immobiliarios (UCI), which has operations in Spain and Portugal, is increasing loans to homeowners and building management groups for energy-efficiency initiatives. Their Residential Energy Rehabilitation initiative aims to remodel and encourage

2166-556: A long trend in a wider recognition of energy efficiency as the "first fuel", meaning the ability to replace or avoid the consumption of actual fuels. In fact, International Energy Agency has calculated that the application of energy efficiency measures in the years 1974-2010 has succeeded in avoiding more energy consumption in its member states than is the consumption of any particular fuel, including fossil fuels (i.e. oil, coal and natural gas). Moreover, it has long been recognized that energy efficiency brings other benefits additional to

2280-446: A low-energy mode after a certain time. Many countries identify energy-efficient appliances using energy input labeling . The impact of energy efficiency on peak demand depends on when the appliance is used. For example, an air conditioner uses more energy during the afternoon when it is hot. Therefore, an energy-efficient air conditioner will have a larger impact on peak demand than off-peak demand. An energy-efficient dishwasher, on

2394-465: A negative exponential decay function linked to a building’s physical life expectancy". According to their study, a building reaches its maximum potential for adaptive reuse at a point when the building's age and its useful life merge or meet. At this point, the building's adaptive reuse potential is either an upward curve or a downward curve which can determine whether the potential is high, medium or low. The adaptive reuse potential calculator establishes

2508-412: A neighborhood which may be otherwise decaying or be at a threat of vandalism. This upward trend may create lucrative rent opportunities for building owners and dwellers of the neighborhood. This survey can be in the form of a physical inspection of the neighborhood and/or a detailed study of the zoning map of that region. Pedestrian activity, presence of sidewalks, street lights, benches and public parks and

2622-1018: A net increase in resource use and associated pollution. These are examples of the direct rebound effect . Estimates of the size of the rebound effect range from roughly 5% to 40%. The rebound effect is likely to be less than 30% at the household level and may be closer to 10% for transport. A rebound effect of 30% implies that improvements in energy efficiency should achieve 70% of the reduction in energy consumption projected using engineering models. Modern appliances, such as, freezers , ovens , stoves , dishwashers , clothes washers and dryers, use significantly less energy than older appliances. Current energy-efficient refrigerators, for example, use 40 percent less energy than conventional models did in 2001. Following this, if all households in Europe changed their more than ten-year-old appliances into new ones, 20 billion kWh of electricity would be saved annually, hence reducing CO 2 emissions by almost 18 billion kg. In

2736-403: A new energy efficiency target of 27% or greater by 2030. One mechanism used to achieve the target of 27% is the 'Suppliers Obligations & White Certificates'. The ongoing debate around the 2016 Clean Energy Package also puts an emphasis on energy efficiency, but the goal will probably remain around 30% greater efficiency compared to 1990 levels. Some have argued that this will not be enough for

2850-400: A new use or purpose for obsolete buildings can be a wonderful resource to a community by "keeping neighborhoods occupied and vital". According to Yung and Chan, "adaptive reuse is a new kind of maintainable rebirth of city, as it covers the building’s lifetime and evades destruction waste, encourages recycles of the embodied dynamism and also delivers substantial social and economic profits to

2964-486: A number of processes and energy services that are widely used in many industries. Various industries generate steam and electricity for subsequent use within their facilities. When electricity is generated, the heat that is produced as a by-product can be captured and used for process steam, heating or other industrial purposes. Conventional electricity generation is about 30% efficient, whereas combined heat and power (also called co-generation ) converts up to 90 percent of

3078-466: A part of our cultural heritage ; they should be preserved because of their "architectural beauty" and the "character and scale they add to the built environment". Retention and rehabilitation of existing buildings also reduces the consumption of building materials , resources, energy and water needed for new construction. Building owners, architects, developers and other stakeholders undergo an in-depth process of decision making before determining whether

3192-511: A per capita basis while national US consumption doubled. As part of its strategy, California implemented a "loading order" for new energy resources that puts energy efficiency first, renewable electricity supplies second, and new fossil-fired power plants last. States such as Connecticut and New York have created quasi-public Green Banks to help residential and commercial building-owners finance energy efficiency upgrades that reduce emissions and cut consumers' energy costs. Energy conservation

3306-511: A percentage. This decay curve in buildings can be used to establish an ARP score, which is expressed in percentage. Cities can rank their existing buildings as per their adaptive reuse potential and this data can be used by government authorities at any point in time. An adaptive reuse score of 50% or above is considered high. A low ARP score is anything below 20%. Anything between that range is considered moderate. Shen and Langston devised this concept of ARP as "rising from zero to its maximum score at

3420-418: A public park. The Reading Viaduct park plan gained momentum in 2009 when Philadelphia's Center City District (CCD), and its influential president Paul Levy, became enamored of the idea and ultimately became a partner to help manage the project. CCD announced on Tuesday, February 6, 2018 that the first phase of the quarter-mile-long, elevated park would open in spring 2018. The actual grand opening of The Rail park

3534-482: A significant rise in energy efficiency investments reported by SMEs and mid-cap companies. Energy efficiency is central to energy policy in Germany . As of late 2015, national policy includes the following efficiency and consumption targets (with actual values for 2014): Recent progress toward improved efficiency has been steady aside from the financial crisis of 2007–08 . Some however believe energy efficiency

3648-546: A significant role, both between improved vehicle efficiency and the distance travelled, and between improved vehicle efficiency and an increase in vehicle weights and engine power. In 2014, the German federal government released its National Action Plan on Energy Efficiency (NAPE). The areas covered are the energy efficiency of buildings, energy conservation for companies, consumer energy efficiency, and transport energy efficiency. The central short-term measures of NAPE include

3762-491: A successful adaptive reuse project, the designers must keep the building's energy use intensity at utmost importance. Building materials are generally procured from the Earth's strata or are end products of processed natural components. These resources are limited. Irresponsible extraction of natural compounds for building material manufacture can deplete these natural compounds from the earth. Moreover, extraction can cause harm to

3876-461: A suitable concept to objectively reduce the expected physical life of a building to its expected useful life. A discounting philosophy is adopted, whereby the annual obsolescence rate across all criteria is the "discount rate" that performs this transformation. An algorithm based on a standard decay (negative exponential) curve produces an index of reuse potential (known as the ARP score) and is expressed as

3990-464: A survey conducted by Bullen and Love, it was observed that building owners and operators were most concerned about a multitude of financial considerations, while deciding whether to reuse their built assets. These include development and construction costs, marketing and maintenance costs. Most adaptive reuse projects depend on their economic feasibility determined by the building's existing physical configuration and condition. According to Bullen and Love,

4104-533: A sustainable way, through transforming these buildings into usable and accessible units. The adaptive reuse strategy would also enable the local authority and owners of older vacant buildings in urban areas to minimize their economic, social and environmental costs, in a quest for a continued urban expansion and development. The current climate change reality requires integrating the global sustainability challenge of conserving natural resources for future generations with improving resilience and adaptive capacity within

4218-431: A thorough inspection and was identified with extreme corrosion in its exterior steel columns (100% of web loss and 40% of flange loss). This condition posed a threat to the public safety and had to undergo immediate restriction of live load in spite of additional bracing of critical bents. Such inspections conclude with the preparation of a detailed report summarizing the findings of the investigation. The direct inspection of

4332-430: A very important aspect of any urban regeneration scheme. The adaptation process implies selecting relevant novel technologies and design concepts that will support the older buildings to adjust successfully to contemporary requirements without destroying the existing urban form. Adopting the adaptive reuse approach for the redevelopment of older vacant buildings provides added benefits to the regeneration of an urban area in

4446-671: A wide variety of applications. The efficiency of pumps and compressors depends on many factors but often improvements can be made by implementing better process control and better maintenance practices. Compressors are commonly used to provide compressed air which is used for sand blasting, painting, and other power tools. According to the US Department of Energy, optimizing compressed air systems by installing variable speed drives, along with preventive maintenance to detect and fix air leaks, can improve energy efficiency 20 to 50 percent. The estimated energy efficiency for an automobile

4560-479: Is 280 Passenger-Mile/10 Btu. There are several ways to enhance a vehicle's energy efficiency. Using improved aerodynamics to minimize drag can increase vehicle fuel efficiency . Reducing vehicle weight can also improve fuel economy, which is why composite materials are widely used in car bodies. More advanced tires, with decreased tire to road friction and rolling resistance, can save gasoline. Fuel economy can be improved by up to 3.3% by keeping tires inflated to

4674-400: Is a significant change in lowering the carbon footprint . A building's location and surroundings play a key role in regulating its temperature and illumination. For example, trees, landscaping, and hills can provide shade and block wind. In cooler climates, designing northern hemisphere buildings with south facing windows and southern hemisphere buildings with north facing windows increases

4788-406: Is adaptive reuse". They studied that "a huge focus on economic factors alone has led to the destruction of buildings well short of their physical lives". Shen and Langston developed an integrated model for the assessment of adaptive reuse potential by comparing case studies of one urban and one non-urban setting. The basis of this model lies in that "opportunity rises and falls within the confines of

The former Reading Railroad train trestle, the Reading Viaduct , is a defining feature of the Callowhill neighborhood. Neighborhood groups proposed that the abandoned structure be maintained as

5016-613: Is always more economical" and "renovation is universally more expensive" due to their own involvement with adaptive reuse projects. Others claim that the return on investment is enhanced when using an older building because of the savings involved. One Canadian developer claims that reusing buildings generally represents a saving of between 10 and 12% over building new. In terms of profitability, there are also assertions that adaptive reuse projects often have an uncertainty to their profitably that newer developments lack. When looking for funding to build, these considerations must be addressed. In

5130-464: Is an important component in building construction. Water is needed at every stage of a building's life, from building material extraction to manufacture, on-site construction processes such as concrete mixing, cleaning, etc., operational phase in the form of plumbing for human use and landscaping and fire safety, and at the end of its life for recycling building materials or disposing them. Selecting adaptive reuse over brand new construction can help relieve

5244-458: Is because they make energy services cheaper, and so consumption of those services increases. For example, since fuel efficient vehicles make travel cheaper, consumers may choose to drive farther, thereby offsetting some of the potential energy savings. Similarly, an extensive historical analysis of technological efficiency improvements has conclusively shown that energy efficiency improvements were almost always outpaced by economic growth, resulting in

5358-417: Is broader than energy efficiency in including active efforts to decrease energy consumption, for example through behaviour change , in addition to using energy more efficiently. Examples of conservation without efficiency improvements are heating a room less in winter, using the car less, air-drying your clothes instead of using the dryer, or enabling energy saving modes on a computer. As with other definitions,

5472-438: Is delivered as natural gas , petroleum fuels , and electricity . In addition some industries generate fuel from waste products that can be used to provide additional energy. Because industrial processes are so diverse it is impossible to describe the multitude of possible opportunities for energy efficiency in industry. Many depend on the specific technologies and processes in use at each industrial facility. There are, however,

5586-492: Is dictated by whatever process (such as coal-burning, hydroelectric, or renewable source) created the power. Plug-ins can typically drive for around 40 miles (64 km) purely on electricity without recharging; if the battery runs low, a gas engine kicks in allowing for extended range. Finally, all-electric cars are also growing in popularity; the Tesla Model S sedan is the only high-performance all-electric car currently on

5700-467: Is important that the condition of the existing building is thoroughly assessed. A condition assessment primarily inspects a building's structural integrity, roofing, masonry, plaster, wood-work, tiling and the mechanical, electrical and plumbing systems. The in-depth inspection of buildings can be expensive. Nevertheless, building condition assessment is critical to the success of an adaptive reuse project and must not be avoided at any cost because this expense

5814-579: Is important to examine these exterior walls for future fenestration and air conditioning ducts. Buildings undergoing adaptive reuse often lack modern and energy efficient MEP systems and appliances. Heating: Determining the capacity of the heating plant for the new building use and occupancy. Existing heating systems involving boilers and burners and metal piping could be salvaged for recycling. Ventilation: Office and commercial buildings require ventilation. Toilets and kitchens also need ventilation. The floor height must be able to accommodate fan equipment. If

5928-821: Is important to the society because old buildings are critical to the image and history of a society. They agreed that historical buildings add to the aesthetics of a townscape and should be preserved and reused. Buildings consume high amounts of energy during their life-cycle. New construction requires new building materials and other resources which possess high embodied energy (throughout their extraction, manufacture, transportation, packaging and assembly phases). Additionally, they also cause high environmental damage such as global warming , eutrophication , ocean acidification , ozone layer depletion , carbon emission which in turn harms human health and quality of life. From this standpoint, there are several environmental benefits associated with building recycling or adaptive reuse. Water

6042-604: Is insignificant relative to the injury or loss of life that a building failure might cause. One logical reason, as explained by the American Society of Civil Engineers, is that even a very well constructed building could undergo serious deterioration and eventually failure, if proper maintenance is not performed in the operational phase of the building. For example, in the year 1984, the New York City Passenger Ship Terminal went through

6156-408: Is limited flexibility in the building codes , limited plot ratio bonuses and an overall "lack of encouragement" by state and local governments to implement innovative adaptive reuse designs. Suggested solutions from some survey respondents include establishing a mandate to only lease buildings that have undergone adaptive reuse with a high Energy Star rating. Some of the architects thought that there

6270-584: Is needed to address heating and cooling: there is more heat wasted during electricity production in Europe than is required to heat all buildings in the continent. All in all, EU energy efficiency legislation is estimated to deliver savings worth the equivalent of up to 326 million tons of oil per year by 2020. The EU set itself a 20% energy savings target by 2020 compared to 1990 levels, but member states decide individually how energy savings will be achieved. At an EU summit in October 2014, EU countries agreed on

6384-482: Is not only equivalent to a 1.4-liter 16v engine, but fuel consumption is 30% lower." Energy-efficient vehicles may reach twice the fuel efficiency of the average automobile. Cutting-edge designs, such as the diesel Mercedes-Benz Bionic concept vehicle have achieved a fuel efficiency as high as 84 miles per US gallon (2.8 L/100 km; 101 mpg ‑imp ), four times the current conventional automotive average. The mainstream trend in automotive efficiency

6498-446: Is still under-recognized in terms of its contribution to Germany's energy transformation (or Energiewende ). Efforts to reduce final energy consumption in transport sector have not been successful, with a growth of 1.7% between 2005 and 2014. This growth is due to both road passenger and road freight transport. Both sectors increased their overall distance travelled to record the highest figures ever for Germany. Rebound effects played

6612-719: Is the National Partnership Agreement on Energy Efficiency. In August 2017, the Government of Canada released Build Smart - Canada's Buildings Strategy, as a key driver of the Pan-Canadian Framework on Clean Growth and Climate Change , Canada's national climate strategy. A 2011 Energy Modeling Forum study covering the United States examined how energy efficiency opportunities will shape future fuel and electricity demand over

6726-548: Is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems. For example, insulating a building allows it to use less heating and cooling energy while still maintaining a comfortable temperature . Another method is to remove energy subsidies that promote high energy consumption and inefficient energy use. Improved energy efficiency in buildings , industrial processes and transportation could reduce

6840-561: Is the rise of electric vehicles (all-electric or hybrid electric). Electric engines have more than double the efficiency of internal combustion engines. Hybrids, like the Toyota Prius , use regenerative braking to recapture energy that would dissipate in normal cars; the effect is especially pronounced in city driving. Plug-in hybrids also have increased battery capacity, which makes it possible to drive for limited distances without burning any gasoline; in this case, energy efficiency

6954-438: Is to reduce greenhouse gas emissions and hence work towards climate action . A focus on energy efficiency can also have a national security benefit because it can reduce the amount of energy that has to be imported from other countries. Energy efficiency and renewable energy go hand in hand for sustainable energy policies. They are high priority actions in the energy hierarchy . Energy productivity , which measures

In the European Union, 78% of enterprises proposed energy-saving methods in 2023, 67% listed energy contract renegotiation as a strategy, and 62% stated passing on costs to consumers as a plan to deal with energy market trends. Larger organisations were found more likely to invest in energy efficiency, green innovation, and climate change, with

7410-485: The Paris Agreement's goals. Energy can be conserved by increasing the technical efficiency of appliances, vehicles, industrial processes, and buildings. If the demand for energy services remains constant, improving energy efficiency will reduce energy consumption and carbon emissions. However, many efficiency improvements do not reduce energy consumption by the amount predicted by simple engineering models. This

According to a 2009 study from McKinsey & Company the replacement of old appliances is one of the most efficient global measures to reduce emissions of greenhouse gases. Modern power management systems also reduce energy usage by idle appliances by turning them off or putting them into

7638-444: The adaptive reuse decision making was fundamentally driven by a "desire for short-term profits". However, most of the survey respondents were rarely concerned about the sustainability and environmental concerns associated with adaptive reuse decision making. Nevertheless, many of these developers were aware of the positive impact that building reuse and sustainability can have on their corporate image. Building owners are concerned with

7752-434: The adaptive reuse of a building which included finding tenants, the threat of building not meeting the demand of the end users, lack of structural stability and structure and material decay during the reconstruction phase of the project. In Bullen and Love's survey, many respondents thought that there was not enough support and incentives from the government for carrying out adaptive reuse of built assets. They felt that there

7866-493: The adaptive reuse style. This varying perception of a building's form, function and style depended on the occupant age group. Sometimes, built assets cannot be considered suitable for adaptive reuse, simply because of the nature of their built form or the condition that they are in. For example, one cannot make the most out of a highly compartmentalized, single use building such as a prison. Mid 1900s low-rise apartments that have low floor area ratios (FAR) and which may be in some of

The 'Engine of the year 2011' is the Fiat TwinAir engine equipped with an MHI turbocharger. "Compared with a 1.2-liter 8v engine, the new 85 HP turbo has 23% more power and a 30% better performance index. The performance of the two-cylinder

8094-479: The amount of sun (ultimately heat energy) entering the building, minimizing energy use, by maximizing passive solar heating . Tight building design, including energy-efficient windows, well-sealed doors, and additional thermal insulation of walls, basement slabs, and foundations can reduce heat loss by 25 to 50 percent. Dark roofs may become up to 39 °C (70 °F) hotter than the most reflective white surfaces . They transmit some of this additional heat inside

8208-486: The boundary between efficient energy use and energy conservation can be fuzzy, but both are important in environmental and economic terms. Energy efficiency—using less energy to deliver the same goods or services, or delivering comparable services with less goods—is a cornerstone of many sustainable energy strategies. The International Energy Agency (IEA) has estimated that increasing energy efficiency could achieve 40% of greenhouse gas emission reductions needed to fulfil

8322-401: The building system, including the structure, the shell and even the interior materials. This type of revitalization is not restricted to buildings of historic significance and can be a strategy adopted in case of obsolete buildings. Some urban planners see adaptive reuse as an effective way of reducing urban sprawl and environmental impact. Revitalizing the existing built fabric by finding

8436-437: The building. US Studies have shown that lightly colored roofs use 40 percent less energy for cooling than buildings with darker roofs. White roof systems save more energy in sunnier climates. Advanced electronic heating and cooling systems can moderate energy consumption and improve the comfort of people in the building. Proper placement of windows and skylights as well as the use of architectural features that reflect light into

8550-462: The buildings of the 1960s and 1970s in Perth were badly constructed, used ineffective thermal insulation materials and details and have low suitability for adaptive reuse. On the other hand, the built form of the 1980s was deemed to be engineered to specifications and could accommodate an adaptive reuse model. The survey respondents expressed several concerns and risks that could arise during and after

The adaptive reuse of existing buildings can be adopted to facilitate climate change mitigation progressively. explored the applicability of the adaptive reuse concept as a sustainable tool for climate change mitigation. In an adaptive reuse decision-making setting, there is usually an occurrence of conflicting beliefs, opinions, interests, and resources among relevant stakeholders. Knowing who these stakeholders are and why, through

8778-412: The cities' prime locations cannot be considered profitable for adaptive reuse. In such scenarios, it would be more profitable for the developers to demolish and replace the existing building with a high-rise that has more space to sell. Often, when building owners cannot find an obvious use for a building, it is left to degenerate and decay and eventually collapse. This may pose as a threat to the safety of

8892-446: The commercial performance of buildings in terms of "tenant needs, investment returns, maintenance, repair costs, operational costs, productivity levels, employee retention rates, aesthetics of building and its market value". Building stakeholders often marketed their reused built assets centered around "epoch and utility" and "character and ambiance". Some end users were more attracted to modern architecture while others were more into

9006-486: The core of a society. Cities and communities grow organically around important buildings followed by the commercial development of those neighborhoods. These buildings and the development around them soon become the heart of a community upon which people's life depends. Therefore, regular maintenance and reuse of existing structures can help communities avoid the trauma caused by dilapidation, abandonment and clearance. As these heritage settlements have been getting crowded in

9120-467: The correct pressure. Replacing a clogged air filter can improve a cars fuel consumption by as much as 10 percent on older vehicles. On newer vehicles (1980s and up) with fuel-injected, computer-controlled engines, a clogged air filter has no effect on mpg but replacing it may improve acceleration by 6-11 percent. Aerodynamics also aid in efficiency of a vehicle. The design of a car impacts the amount of gas needed to move it through air. Aerodynamics involves

9234-403: The development of a performance-based framework, to prioritise the most suitable historical building options for adaptive reuse intervention from a list of underutilised buildings. Framework Validation: balanced the diverse interests of all stakeholders in the adaptive reuse decision-making process. According to Zaitzevsky and Bunnell, old buildings physically link us to our past and become

9348-488: The existing building consists some duct work, it should be tested for obstructions, deterioration and air leakage. Air conditioning: Air conditioning ducting and equipment can be expensive and demand a lot of ceiling space. These economical implications must be considered for the new use of the building before deciding the installation of an air conditioning system. Plumbing: Old buildings used galvanized iron pipes for plumbing which may be subject to serious deterioration over

9462-586: The fuel into usable energy. Advanced boilers and furnaces can operate at higher temperatures while burning less fuel. These technologies are more efficient and produce fewer pollutants. Over 45 percent of the fuel used by US manufacturers is burnt to make steam. The typical industrial facility can reduce this energy usage 20 percent (according to the US Department of Energy ) by insulating steam and condensate return lines, stopping steam leakage, and maintaining steam traps. Electric motors usually run at

9576-461: The introduction of competitive tendering for energy efficiency, the raising of funding for building renovation, the introduction of tax incentives for efficiency measures in the building sector, and the setting up energy efficiency networks together with business and industry. In 2016, the German government released a green paper on energy efficiency for public consultation (in German). It outlines

9690-796: The life expectancy of built assets, their energy and environmental performance and the high operating costs which may appear due to poor mechanical equipment, services, building materials and construction. Developers saw a thorough potential in saving groundwork and excavation costs by using an adaptive reuse model for their property. Additionally, they thought that "in Central Business District locations, built assets are an attractive investment option for reuse projects, as premium prices and rents can be obtained for an office space". Best rents can be obtained only when these remodeled buildings hold "high-quality finishes" and have high Energy Star rating appliances. Building owners also considered

9804-773: The market. Cities around the globe light up millions of streets with 300 million lights. Some cities are seeking to reduce street light power consumption by dimming lights during off-peak hours or switching to LED lamps. LED lamps are known to reduce the energy consumption by 50% to 80%. There are several ways to improve aviation's use of energy through modifications aircraft and air traffic management. Aircraft improve with better aerodynamics, engines and weight. Seat density and cargo load factors contribute to efficiency. Air traffic management systems can allow automation of takeoff, landing, and collision avoidance, as well as within airports, from simple things like HVAC and lighting to more complex tasks such as security and scanning. At

9918-400: The monetary value of these multiple benefits have been developed, including e.g. the choice experiment method for improvements that have a subjective component (such as aesthetics or comfort) and Tuominen-Seppänen method for price risk reduction. When included in the analysis, the economic benefit of energy efficiency investments can be shown to be significantly higher than simply the value of

10032-523: The natural habitat and biodiversity of the region where materials are extracted. Therefore, a project that uses minimum new building material and uses more of recycled materials is a more sustainable and responsible choice for a building material. According to Chusid's "urban ore" concept, existing buildings that are fast approaching dilapidation or disuse are a "mine of raw materials for new projects". Shen and Langston built upon this idea and said that "an even more effective solution than raw material recovery

10146-732: The neighborhood "The Loft District". In 2010 the Callowhill Industrial Historic District was added to the National Register of Historic Places . Callowhill is physically cut off from its neighbor to the south, Chinatown , by the Vine Street Expressway . This has largely prevented Chinese businesses from spreading north, although some industrial and storage uses by the Chinese community have been placed in Callowhill. Vine Street

10260-495: The neighborhood. Decaying buildings may even be subject to vandalism and become spaces for anti-social activities and may have a negative impact on the value of the properties in their vicinity. Bullen and Love's survey respondents thought that "the benefits of reusing their existing facility could include avoiding the disruption of relocation, reducing maintenance and running costs". A reuse project should not compromise on satisfying user needs. The survey respondents suggested that

10374-495: The operational and commercial performance of built assets. Adaptive reuse of buildings can be an attractive alternative to new construction in terms of sustainability and a circular economy . It has prevented thousands of buildings' demolition and has allowed them to become critical components of urban regeneration . Not every old building can qualify for adaptive reuse. Architects, developers, builders and entrepreneurs who wish to become involved in rejuvenating and reconstructing

10488-415: The other hand, uses more energy during the late evening when people do their dishes. This appliance may have little to no impact on peak demand. Over the period 2001–2021, tech companies have replaced traditional silicon switches in an electric circuit with quicker gallium nitride transistors to make new gadgets as energy efficient as feasible. Gallium nitride transistors are, however, more costly. This

10602-482: The output and quality of goods and services per unit of energy input, can come from either reducing the amount of energy required to produce something, or from increasing the quantity or quality of goods and services from the same amount of energy. From the point of view of an energy consumer , the main motivation of energy efficiency is often simply saving money by lowering the cost of purchasing energy. Additionally, from an energy policy point of view, there has been

10716-591: The past decades, people have been looking for farther lands for development. This rapid urbanization and urban sprawl cause several harms to our planet and the society. Lack of adaptive reuse of existing built assets, on a societal level, has caused disturbance due to dislocation of residents, economic decline and disruption of community life, eventually leading to abandoned and obsolete neighborhoods. Old buildings are often found in fully developed neighborhoods where public amenities like sewers, water lines, roads, etc. have already been established. Adaptive reuse means that

10830-420: The planet of such water loads. Just as water is needed in every stage of a building's life, so is energy. This energy is conventionally obtained from non-renewable sources and causes high carbon emission. Minimizing fossil fuel depletion and carbon emission can be huge contributing factors to reducing global warming and mitigating climate change . Choosing to demolish an existing built asset and then constructing

10944-608: The point of its useful life, and then falling back to zero as it approaches physical life". When the "current building age" is identified to be close to or end of its useful life, is the right time for builders to commence redesign. Buildings have a high impact on the environment, the economy and our society. Adaptive reuse has several benefits to mitigate those high impacts. Adaptive reuse projects are, in many ways, different from conventional new construction projects and must be planned and managed differently. Before starting an adaptive reuse project and even considering refurbishment, it

11058-543: The potential challenges and actions needed to reduce energy consumption in Germany over the coming decades. At the document's launch, economics and energy minister Sigmar Gabriel said "we do not need to produce, store, transmit and pay for the energy that we save". The green paper prioritizes the efficient use of energy as the "first" response and also outlines opportunities for sector coupling , including using renewable power for heating and transport. Other proposals include

11172-474: The potential to work in phases or parts. A major advantage of renovating an existing building is that a refurbished portion of the building becomes suitable for occupancy before completion of the whole project. This provides as a huge advantage for private developers as it keeps the cash inflow during while the rest of the project undergoes construction. Keeping in mind the conclusions from structural and architectural survey, neighborhood survey and marketing survey,

11286-416: The presence of well-occupied shops and buildings can tell us a lot about neighborhoods. After the neighborhood has been established to be stable and safe and free of any infringing decay, the next step is to determine what amenities it has to offer in terms of roadways, public transportation, shopping and eating, hospitals, schools and libraries and so on. As discussed previously, adaptive reuse projects have

11400-490: The progression of cultural evidence to the past. In a fast-growing urbanizing world, these heritage values viewed as public goods could aid the significance of a town's cultural heritage and unique competitiveness. Heritage preservation charters mandate that when historical buildings with heritage values are being redeveloped, their architectural and heritage character should be maintained and conserved for sustainability. Accordingly, this mandate on heritage preservation has led to

11514-475: The reduction of energy consumption. Some estimates of the value of these other benefits, often called multiple benefits , co-benefits , ancillary benefits or non-energy benefits , have put their summed value even higher than that of the direct energy benefits. These multiple benefits of energy efficiency include things such as reduced greenhouse gas emissions , reduced air pollution and improved health, and improved energy security . Methods for calculating

11628-440: The saved energy. Energy efficiency has proved to be a cost-effective strategy for building economies without necessarily increasing energy consumption . For example, the state of California began implementing energy-efficiency measures in the mid-1970s, including building code and appliance standards with strict efficiency requirements. During the following years, California's energy consumption has remained approximately flat on

11742-509: The scheduling of several heritage buildings into district plans, thereby protecting them from unsympathetic alterations or demolition through regulations. Built heritage conservation through adaptive reuse could therefore be used to promote sustainable historical and cultural development of urban areas. Parameters to prioritise historical buildings for adaptive reuse and the characterisation of adaptive reuse stakeholders are also noted. The reuse of older vacant buildings for other purposes forms

11856-468: The settling of basement floors or upper floors which direct them to a problem in the foundation. These signs can also be detected from window sills and cornices. Appropriate survey instruments such as plumb bobs and spirit levels are recommended for use instead of a naked eye inspection. If the problem seems too severe, a test boring may reveal the cause of the problem. Additionally, the building code should be examined for fireproofing requirements. Analyzing

11970-431: The stakeholders of the built asset are relieving governments and municipalities off the load of having to supply these public amenities on distant plots. In a survey conducted by researcher Sheila Conejos, several architects, developers and building stakeholders were asked about their opinion on the social implications of adaptive reuse of existing buildings. It was observed that most respondents thought that adaptive reuse

12084-496: The structural strength of the existing building. The floor system in old buildings is usually strong enough to satisfy present codes. If not, additional supporting members may be necessary. The floor and ceiling height should be able to accommodate additional stairways, vertical plumbing, electrical and HVAC. In some cases, an elevator may have to be installed. The building envelope should be examined thoroughly for cracks, watertightness (infiltration or leaks) and mortar joints. It

12198-619: The structural strength requires expertise and is one of the most crucial in terms of occupant safety. On-site inspection along with a study of existing floor plans can help engineers determine the structural stability. In some case, when the building drawings may not be available, engineers may have to scrape off the plaster to reveal the underlying structure. Wooden members of the structural system should be especially checked for rot or termite infestation. Iron or steel must be checked for corrosion and loose bearings or bolting. Additional future dead and live loads must be kept in mind while designing with

12312-442: The structural system is required to a certain degree which is decided by the judgement of an experienced civil engineer. After identifying the stability and soundness of a building, it is important to survey the neighborhood to find the potential use and function of the adaptive reuse project for that segment of the market or region that the building owners wish to attract. In many cases, an adaptive reuse project might help stabilize

12426-483: The use of renewable energy in at least 3720 homes in Madrid, Barcelona, Valencia, and Seville. The works are expected to mobilize around €46.5 million in energy efficiency upgrades by 2025 and save approximately 8.1 GWh of energy. It has the ability to reduce carbon emissions by 7,545 tonnes per year. In May 2016 Poland adopted a new Act on Energy Efficiency, to enter into force on 1   October 2016. In July 2009,

12540-1157: The world". Benefits: Typically categorised under economic , social , cultural and historical , and environmental benefits . The most significant benefits of adaptive reuse of existing buildings include increased economic opportunities, urban regeneration, preserved cultural and historical heritage values, reduced landfill demolition waste, increased energy efficiency , extended building usefulness, and cost-effectiveness, enhanced property value, improved life quality, reduced carbon emissions, and lesser energy consumption. Challenges: Typically categorised under building regulatory requirements and governance , financial , management , and complexities and uncertainties challenges . The most significant challenges of adaptive reuse of existing buildings include structural integrity issues, compliance with building code regulations, government anti-adaptive reuse policies, lack of awareness, high maintenance cost, uncertainties surrounding existing building information, lack of incentives, and lack of decision-making tools and stakeholder participation. A majority of historical buildings provide physical links and

12654-443: The world's energy needs in 2050 by one third. There are two main motivations to improve energy efficiency. Firstly, one motivation is to achieve cost savings during the operation of the appliance or process. However, installing an energy-efficient technology comes with an upfront cost, the capital cost . The different types of costs can be analyzed and compared with a life-cycle assessment . Another motivation for energy efficiency

12768-518: The years. Proper connection to municipal sewers must be evaluated and fixed if broken. Electrical: While the electrical wiring may still be intact, the panel boards, junction boxes and electrical feeders may not be as per the present day fire codes. Additionally, the switch boards may be outdated and have to be replaced. The architect and engineers must also determine of additional transformer vaults and feeder lines are necessary. Efficient energy use Efficient energy use , or energy efficiency ,

12882-609: Was a high dependency and credit given to energy and green building rating systems such as the "Green Star Environment Rating System" but not enough credit was given to the improvements carried out during adaptive reuse and its sustainable outcomes such as the recycling of building materials, reduced energy and water consumption and reduced environmental impacts like global warming potential , lake eutrophication potential and ozone layer depletion . One architect thought that "undertaking exemplar adaptive reuse demonstration projects for industry professionals to assess and emulate would display

12996-422: Was held on June 14, 2018, attracting a large crowd. Philadelphia Traffic Court is in Callowhill, at Spring Garden Street and North 8th Street. Adaptive reuse Adaptive reuse refers to the process of reusing an existing building for a purpose other than which it was originally built or designed for. It is also known as recycling and conversion. Adaptive reuse is an effective strategy for optimizing
