Trigeneration and Creating World-LEEDing Buildings | sustainable architecture | Scoop.it
Renewable energy and energy efficient technologies are generally lauded for their inclusion in projects but, while we understand they are relevant, we often do not understand exactly what they do and how they make energy savings possible.

One technology sneaking under the radar is the trigeneration system. As the name would suggest, a it is the simultaneous producer of three energy forms: electricity, heating and cooling. Waste heat gathered from the generation of electricity – created through solar collectors in high energy efficiency systems – is captured and is then used to heat and cool water. An absorption chiller, powered by the captured heat, operates like a refrigerator, creating low temperatures which can be channeled into air-conditioning systems. The use of wasted energy and the close-range electricity exchange allow some systems to run at 80 to 90 per cent energy efficiency levels.

As part of the ‘AIA Top Ten’, architectural firm Perkins + Will’s redevelopment of a midtown Atlanta building at 1315 Peachtree Street, which was originally built in 1986, is a prime example of how the trigeneration system can be implemented into a project...
