Comprehensive Building Performance Monitoring: Supporting Outcome-Based Design and Construction Provisions

建筑能耗占加拿大温室气体排放量的28%。为了减少建筑物对环境的影响，并改善居住者的健康和舒适性，管理建筑设计的法规和标准变得越来越严格。对这些规定的遵守情况是在建筑物入伙前进行评估的，因此我们假设建筑物完全按照设计工作，但事实并非如此。建筑、运营和居住者行为的影响导致了具体表现与实际表现之间的差距。这种性能差距具有严重的后果，包括阻碍监管部门努力减少建筑物对环境的影响，影响高性能建筑评级系统的可信度，并给业主带来关于建筑性能及其投资的长期价值的不确定性。

Building energy use is responsible for 28% of Canada’s greenhouse gas emissions. To reduce the environmental impact of buildings as well as improve occupant health and comfort, codes and standards governing building design are becoming increasingly stringent. Compliance with these provisions is assessed before the building is occupied and so we assume buildings perform exactly as designed, but this is not the case. The impact of construction, operation and occupant behavior contribute to a gap between specified and actual performance. This performance gap has serious consequences including impeding regulatory efforts to reduce the environmental impact of buildings, affecting the credibility of high performance building rating systems and creating uncertainty for the owners about building performance and the long-term value of their investment.
