Building Energy Codes
Building energy codes contain minimum energy efficiency provisions for residential and commercial buildings. The codes are recognized as a simple and cost-effective way to reduce energy consumption and lower energy bills. Buildings consume 40% of the world's raw materials and energy. Today’s new construction buildings are estimated to have a lifetime of 75 years. It is cheaper and easier to build in energy-saving components at the time of construction, meaning that energy savings opportunities are lost over the lifetime the building if they are not added in during initial construction.
