LEED (Leadership in Energy and Environmental Design) is an internationally recognized green building certification system, providing third-party verification that a building or community was designed, built or renovated using strategies aimed at improving performance across metrics.
ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers), founded in 1894, is a building technology society with more than 54,000 members worldwide publishing internationally recognized standards and guidelines related to HVAC systems.
BIM (Building Information Modeling) is a process involving the generation and management of digital representations of physical and functional characteristics of spaces in buildings.
The building sector can significantly reduce energy use by incorporating energy-efficient strategies into the design, construction, and operation of new buildings and undertaking retrofits to improve the efficiency of existing buildings. It can further reduce dependence on fossil fuel derived energy by increasing use of on-site and off-site renewable energy sources.
