Building Performance Assessment Systems for Sustainable Buildings - LEED, BREEAM, CASBEE

#SmartBuildingsAcademy #LEEDBuilding #BREEAM #CASBEE

Building Performance Assessment Systems are sustainability-related building standards and methodologies recognized worldwide spotlight evaluating environmental performance in buildings

Building Performance Assessment Systems include similar broad evaluation categories, including energy consumption, indoor air quality, site and waste management, water resourcing, building materials, and innovation.

1 - LEED (Leadership in Energy and Environmental Design) and WELL (International Well Building Institute – IWBI) of the United States

2 - BREEAM (Building Research Establishment Environmental Assessment Method) conceptualized in the United Kingdom

3- LBC (Living Building Challenge, the International Living Future Institute’s advanced sustainability measure), CASBEE (Comprehensive Assessment System for Building Environmental Efficiency) from Japan

4 - France’s HQE (High Environmental Quality)

5- Australia’s Green Star

BPASs such as LEED and LBC are leaders in certification programs that focus on “healthy” materials, while also allowing buildings to earn points as they use Smart building technology. They rate new and pre-existing buildings per environmental attributes and sustainability features. For the LBC and LEED certification credits, Smart technology solutions can be customized to make a marked difference in overall on-site energy consumed by buildings. It is essential that building performance be measured quantitatively, in the context of optimizing environmental impact and lifecycle cost of the buildings. Using material that has a Life Cycle Assessment certificate further supports energy goals. The Life Cycle Assessment considers several vital factors, such as energy consumption, use of natural resources, GHG and pollution reduction, etc. Smart Readiness Indicator (SRI) rates its capacity to use new technologies and systems to reduce energy consumption and carbon emissions, and adapt to occupants’ needs.
Sustainability measurement tools are imperative to assess compliance with sustainability principles and encourage reduction of environmental burden. The combination of sustainability measurement tools and technology such as Building Information Modeling (BIM), Building Management Systems (BMS), AI, and Big Data show great promise with further research serving as an anchorage.
