218-904: A white paper entitled "Building Information Modeling," and other software vendors also started to assert their involvement in the field. By hosting contributions from Autodesk, Bentley Systems and Graphisoft, plus other industry observers, in 2003, Jerry Laiserin helped popularize and standardize the term as a common name for the digital representation of the building process. As some BIM software developers have created proprietary data structures in their software, data and files created by one vendor's applications may not work in other vendor solutions. To achieve interoperability between applications, neutral, non-proprietary or open standards for sharing BIM data among different software applications have been developed. Poor software interoperability has long been regarded as an obstacle to industry efficiency in general and to BIM adoption in particular. In August 2004

According to Global status report from
1744-480: A lesser scale, however it is still an effective passive method to reduce environmental impact. The concept of sustainable development can be traced to the energy (especially fossil oil ) crisis and environmental pollution concerns of the 1960s and 1970s. The Rachel Carson book, " Silent Spring ", published in 1962, is considered to be one of the first initial efforts to describe sustainable development as related to green building. The green building movement in
1853-568: A lot of energy. An alternative to this process is converting waste and wastewater into fertilizer, which avoids these costs and shows other benefits. By collecting human waste at the source and running it to a semi-centralized biogas plant with other biological waste, liquid fertilizer can be produced. This concept was demonstrated by a settlement in Lübeck Germany in the late 1990s. Practices like these provide soil with organic nutrients and create carbon sinks that remove carbon dioxide from
1962-482: A model during design. One of the challenges to the proper maintenance and management of existing facilities is understanding how BIM can be utilized to support a holistic understanding and implementation of building management practices and " cost of ownership " principles that support the full product lifecycle of a building.

Deconstruction is a method of harvesting what is commonly considered "waste" and reclaiming it into useful building material. Extending the useful life of a structure also reduces waste – building materials such as wood that are light and easy to work with make renovations easier. To reduce the impact on wells or water treatment plants , several options exist. " Greywater ", wastewater from sources such as dishwashing or washing machines, can be used for subsurface irrigation, or if treated, for non-potable purposes, e.g., to flush toilets and wash cars.

In North America, LCA is rewarded to some extent in the Green Globes rating system, and is part of the new American National Standard based on Green Globes, ANSI/GBI 01-2010: Green Building Protocol for Commercial Buildings . LCA is also included as a pilot credit in the LEED system, though
8284-805: The global CO 2 emissions were 39%. If new technologies in construction are not adopted during this time of rapid growth, emissions could double by 2050, according to the United Nations Environment Program . Glass buildings, especially all-glass skyscrapers, contribute significantly to climate change due to their energy inefficiency. While these structures are visually appealing and allow abundant natural light, they also trap heat, necessitating increased use of air conditioning systems, which contribute to higher carbon emissions. Experts advocate for design modifications and potential restrictions on all-glass edifices to mitigate their detrimental environmental impact. Buildings account for
8393-439: The goal of waste reduction may be applied during the design, construction and demolition phases of a building's life-cycle, it is in the O&M phase that green practices such as recycling and air quality enhancement take place. O&M staff should aim to establish best practices in energy efficiency, resource conservation, ecologically sensitive products and other sustainable practices. Education of building operators and occupants
8502-789: The identification of vulnerabilities in building emergencies. Dynamic information about the building, such as sensor measurements and control signals from the building systems, can also be incorporated within software to support analysis of building operation and maintenance. As such, BIM in facility operation can be related to internet of things approaches; rapid access to data may also be aided by use of mobile devices (smartphones, tablets) and machine-readable RFID tags or barcodes ; while integration and interoperability with other business systems - CAFM , ERP , BMS , IWMS , etc - can aid operational reuse of data. There have been attempts at creating information models for older, pre-existing facilities. Approaches include referencing key metrics such as
8611-467: The last few years have seen a shift away from a prescriptive approach, which assumes that certain prescribed practices are better for the environment, toward the scientific evaluation of actual performance through LCA. Although LCA is widely recognized as the best way to evaluate the environmental impacts of buildings (ISO 14040 provides a recognized LCA methodology), it is not yet a consistent requirement of green building rating systems and codes, despite
8720-620: The late 1990s, with inputs from Georgia Tech , and was approved by the American Institute of Steel Construction as its data exchange format for structural steel in 2000. BIM is often associated with Industry Foundation Classes (IFCs) and aecXML – data structures for representing information – developed by buildingSMART . IFC is recognised by the ISO and has been an official international standard, ISO 16739, since 2013. Construction Operations Building information exchange ( COBie )
8829-579: The lighting quality and energy performance of a structure. Solid wood products, particularly flooring, are often specified in environments where occupants are known to have allergies to dust or other particulates. Wood itself is considered to be hypo-allergenic and its smooth surfaces prevent the buildup of particles common in soft finishes like carpet. The Asthma and Allergy Foundation of America recommends hardwood, vinyl, linoleum tile or slate flooring instead of carpet. The use of wood products can also improve air quality by absorbing or releasing moisture in
8938-541: The local aquifer. Large commercial buildings with water and energy efficiency can qualify for an LEED Certification. Philadelphia's Comcast Center is the tallest building in Philadelphia. It is also one of the tallest buildings in the USA that is LEED Certified. Their environmental engineering consists of a hybrid central chilled water system which cools floor-by-floor with steam instead of water. Burn's Mechanical set-up
9047-451: The main goals of public procurement the "rationalization of designing activities and of all connected verification processes, through the progressive adoption of digital methods and electronic instruments such as Building and Infrastructure Information Modelling". A norm in 8 parts is also being written to support the transition: UNI 11337-1, UNI 11337-4 and UNI 11337-5 were published in January 2017, with five further chapters to follow within
9156-407: The marketplace. The MAS Certified Green Program ensures that any potentially hazardous chemicals released from manufactured products have been thoroughly tested and meet rigorous standards established by independent toxicologists to address recognized long-term health concerns. These IAQ standards have been adopted by and incorporated into the following programs: Also important to indoor air quality
9265-478: The matured definition of 'BIM' specified only about one and a half decade later". The term 'building model' (in the sense of BIM as used today) was first used in papers in the mid-1980s: in a 1985 paper by Simon Ruffle eventually published in 1986, and later in a 1986 paper by Robert Aish – then at GMW Computers Ltd , developer of RUCAPS software – referring to the software's use at London's Heathrow Airport . The term 'Building Information Model' first appeared in
9374-575: The maximum extent, including energy saving, land saving, water saving, material saving, etc., during the whole life cycle of the building, protecting the environment and reducing pollution, providing people with healthy, comfortable and efficient use of space, and being in harmony with nature. Buildings that live in harmony; green building technology focuses on low consumption, high efficiency, economy, environmental protection, integration and optimization.’ Leadership in Energy and Environmental Design (LEED)
9483-400: The model before beginning construction, with opportunities to pre-fabricate or pre-assemble some systems off-site. Waste can be minimised on-site and products delivered on a just-in-time basis rather than being stock-piled on-site. Quantities and shared properties of materials can be extracted easily. Scopes of work can be isolated and defined. Systems, assemblies and sequences can be shown in
9592-517: The most mature BIM solutions on the market." Following its launch in 1987, ArchiCAD became regarded by some as the first implementation of BIM , as it was the first CAD product on a personal computer able to create both 2D and 3D geometry, as well as the first commercial BIM product for personal computers. However, Graphisoft founder Gábor Bojár has acknowledged to Jonathan Ingram in an open letter, that Sonata "was more advanced in 1986 than ArchiCAD at that time", adding that it "surpassed already
9701-543: The overall life cycle energy consumption. Studies such as the U.S. LCI Database Project show buildings built primarily with wood will have a lower embodied energy than those built primarily with brick, concrete, or steel. To reduce operating energy use, designers use details that reduce air leakage through the building envelope (the barrier between conditioned and unconditioned space). They also specify high-performance windows and extra insulation in walls, ceilings, and floors. Another strategy, passive solar building design ,
9810-430: The owner may turn to the model and see that a water valve is located in the suspect location. The owner could also have in the model the specific valve size, manufacturer, part number, and any other information ever researched in the past, pending adequate computing power. Such problems were initially addressed by Leite and Akinci when developing a vulnerability representation of facility contents and threats for supporting
9919-549: The period 2016–2018. The French arm of buildingSMART , called Mediaconstruct (existing since 1989), is supporting digital transformation in France. A building transition digital plan – French acronym PTNB – was created in 2013 (mandated since 2015 to 2017 and under several ministries). A 2013 survey of European BIM practice showed France in last place, but, with government support, in 2017 it had risen to third place with more than 30% of real estate projects carried out using BIM. PTNB
10028-430: The practices or technologies employed in green building are constantly evolving and may differ from region to region, fundamental principles persist from which the method is derived: siting and structure design efficiency, energy efficiency, water efficiency , materials efficiency, indoor environmental quality enhancement, operations and maintenance optimization and waste and toxics reduction. The essence of green building
10137-658: The process of making cement without producing CO 2 is unavoidable. However, using pozzolans clinkers can reduce CO 2 emission while in the process of making cement. The Indoor Environmental Quality (IEQ) category in LEED standards, one of the five environmental categories, was created to provide comfort, well-being, and productivity of occupants. The LEED IEQ category addresses design and construction guidelines especially: indoor air quality (IAQ), thermal quality, and lighting quality. Indoor Air Quality seeks to reduce volatile organic compounds , or VOCs, and other air impurities such as microbial contaminants. Buildings rely on
10246-518: The professionals involved in a project, BIM enables a virtual information model to be shared by the design team ( architects , landscape architects , surveyors , civil , structural and building services engineers , etc.), the main contractor and subcontractors , and the owner/operator. Each professional adds discipline-specific data to the shared model – commonly, a 'federated' model which combines several different disciplines' models into one. Combining models enables visualisation of all models in
10355-512: The prospect of integrating BIM with complementary international standards based classification systems being developed for the Power Plant sector. ISO 19650-1:2018 defines BIM as: The US National Building Information Model Standard Project Committee has the following definition: Traditional building design was largely reliant upon two-dimensional technical drawings (plans, elevations, sections, etc.). Building information modeling extends
10464-564: The published ISO standards related to BIM such as ISO19650 series as determined by the Article 10 (Technical Specification) of the Agreement. Small BIM-related seminars and independent BIM effort existed in South Korea even in the 1990s. However, it was not until the late 2000s that the Korean industry paid attention to BIM. The first industry-level BIM conference was held in April 2008, after which, BIM has been spread very rapidly. Since 2010,
10573-559: The requirements for the BIM Level 3 (iBIM). The Czech BIM Council, established in May 2011, aims to implement BIM methodologies into the Czech building and designing processes, education, standards and legislation. In Estonia digital construction cluster (Digitaalehituse Klaster) was formed in 2015 to develop BIM solutions for the whole life-cycle of construction. The strategic objective of
10682-419: The same place and time. BIM additionally is able to aid in collision detection, identifying the exact location of discrepancies. The BIM concept envisages virtual construction of a facility prior to its actual physical construction, in order to reduce uncertainty, improve safety, work out problems, and simulate and analyze potential impacts. Sub-contractors from every trade can input critical information into
10791-874: The sustainability performance of buildings, indoor environments and districts. Currently, the World Green Building Council is conducting research on the effects of green buildings on the health and productivity of their users and is working with the World Bank to promote Green Buildings in Emerging Markets through EDGE ( Excellence in Design for Greater Efficiencies ) Market Transformation Program and certification. There are also other tools such as NABERS or Green Star in Australia, Global Sustainability Assessment System (GSAS) used in
10900-436: The three primary spatial dimensions (width, height and depth), incorporating information about time (so-called 4D BIM), cost (5D BIM), asset management, sustainability, etc. BIM therefore covers more than just geometry. It also covers spatial relationships, geospatial information, quantities and properties of building components (for example, manufacturers' details), and enables a wide range of collaborative processes relating to
11009-420: The total environmental impact associated with all life-cycle stages of the building project. However, building as a process is not as streamlined as an industrial process, and varies from one building to the other, never repeating itself identically. In addition, buildings are much more complex products, composed of a multitude of materials and components each constituting various design variables to be decided at
11118-573: The tripling of heat pump sales from 2015 to 2022, electric cars accounting for 20% of 2023 vehicle sales, and a potential doubling of China's peak electricity demand by mid-century. India's air conditioner ownership could see a tenfold rise by 2050, causing a sixfold increase in peak electricity demand, which could be halved with efficient practices. By 2050, demand response measures might lower household electricity bills by 7% to 12% in advanced economies and nearly 20% in developing ones, with smart device installations nearly doubling by 2030. The US could see
11227-403: The use of BIM for all government projects over HK$ 30M since 1 January 2018. India Building Information Modelling Association (IBIMA) is a national-level society that represents the entire Indian BIM community. In India BIM is also known as VDC: V irtual D esign and C onstruction. Due to its population and economic growth, India has an expanding construction market. In spite of this, BIM usage
11336-406: The year 2016, buildings consume more than 30% of all produced energy. The report states that "Under a below 2°C trajectory, effective action to improve building energy efficiency could limit building final energy demand to just above current levels, meaning that the average energy intensity of the global building stock would decrease by more than 80% by 2050". Green building practices aim to reduce
11445-664: Was issued as a British Standard: BS 1192-4. In January 2019, ISO published the first two parts of ISO 19650, providing a framework for building information modelling, based on process standards developed in the United Kingdom. UK BS and PAS 1192 specifications form the basis of further parts of the ISO 19650 series, with parts on asset management (Part 3) and security management (Part 5) published in 2020. The IEC/ISO 81346 series for reference designation has published 81346-12:2018, also known as RDS-CW (Reference Designation System for Construction Works). The use of RDS-CW offers
11554-566: Was reported by only 22% of respondents in a 2014 survey. In 2019, government officials said BIM could help save up to 20% by shortening construction time, and urged wider adoption by infrastructure ministries. The Iran Building Information Modeling Association (IBIMA) was founded in 2012 by professional engineers from five universities in Iran, including the Civil and Environmental Engineering Department at Amirkabir University of Technology . While it
11663-712: Was signed in 2009. Sec. 2(g) requires that: "(iii) at least 15 percent of the agency's existing buildings (above 5,000 gross square feet)…meet the Guiding Principles by fiscal year 2015…”. Each of these Guiding Principles has multiple criteria, ranging from reducing building energy use to meeting the EPA 's recycled content recommendations. To measure compliance with the Guiding Principles, federal agencies have options that include EPA's Federal High Performance Sustainable Buildings Checklist, paper evaluations by internal staff, ad hoc evaluations by external consultants, and
11772-638: Was superseded in 2018 by Plan BIM 2022, administered by an industry body, the Association for the Development of Digital in Construction (AND Construction), founded in 2017, and supported by a digital platform, KROQI, developed and launched in 2017 by CSTB (France's Scientific and Technical Centre for Building ).
