Since the 1990s, building performance simulation has undergone the transition from a method used mainly for research to a design tool for mainstream industrial projects. However, the utilization in different countries still varies greatly. Building certification programs like [[Leadership in Energy and Environmental Design|LEED]] (USA), [[BREEAM]] (UK) or [[DGNB]] (Germany) showed to be a good driving force for BPS to find broader application. Also, national building standards that allow BPS based analysis are of good help for an increasing industrial adoption, such as in the United States ([[ASHRAE 90.1]]),<ref name=":1" /> Sweden (BBR),<ref>{{Cite web|url=https://www.boverket.se/en/start-in-english/|title=BBR - Swedish building regulation|access-date=2018-03-29|archive-url=https://web.archive.org/web/20180329085624/http://www.boverket.se/en/start-in-english/|archive-date=2018-03-29|url-status=dead}}</ref> Switzerland (SIA)<ref>{{Cite web|url=http://www.sia.ch/en/the-sia/|title=Swiss society of architects and engineers (SIA)|access-date=2018-03-29}}</ref> and the United Kingdom (NCM).<ref>{{Cite web|url=https://www.uk-ncm.org.uk/|title=UKs National Calculation Method|access-date=2018-03-29}}</ref>

The Swedish building regulations are unique in that computed energy use has to be verified by measurements within the first two years of building operation. Since the introduction in 2007, experience shows that highly detailed simulation models are preferred by modelers to reliably achieve the required level of accuracy. Furthermore, this has fostered a simulation culture where the design predictions are close to the actual performance. This in turn has led to offers of formal energy guarantees based on simulated predictions, highlighting the general business potential of BPS.<ref>{{Cite web|url=http://www.gbpn.org/databases-tools/bc-detail-pages/sweden#Summary|title=Swedish code summarized in global performance network|access-date=2018-03-29}}</ref>
