La Jolla Commons, San Diego, California: The largest net-zero energy building in the U.S employs highly-efficient building envelope technologies like on-site fuel cells, low emissive coatings that reflect invisible long-wave infrared heat, and an under-floor air distribution system. National Renewable Energy Laboratory, Colorado, U.S.A: The building includes rooftop photovoltaic systems and transpired solar collectors to generate the same energy that the structure consumes.ģ.
The Unisphere, Maryland, U.S.A: The Unisphere building possesses solar photovoltaic systems, high-performance electromagnetic envelopes, earth coupled heating-cooling system, etc., to help the building function with no carbon emissions. Some of the examples of NZEBs that have used high-performance building envelope components are:ġ. Building envelopes with technology to harvest solar energy help create sustainable buildings.Įxamples of High-Performance Building Envelopes.Airtight construction prevents leaks, hence preventing heat gain and heat loss.This creates less burden on the A/C or heating systems. Proper insulation to walls controls severe temperature changes within the building during hotter or colder seasons.
#COMPONENTS OF BUILDING ENVELOPE WINDOWS#
The system must also be simple, elegant, and constructed with ease. The cost for this superior performance must be balanced and affordable. Whatever be the components employed, the four key attributes that a high-performance building envelope must possess are:Ī high-performance building envelope should perform at a superior level in functionality and sustainability. High-performance envelopes can be made of various components like windows, walls, doors, insulation, and other systems.
