Two Southern California projects have taken advantage of climate-related and site-specific characteristics to design and construct high-performance, environmentally friendly buildings. Design teams and building owners have used the sun, wind, and moderate temperatures to provide air flow and natural light into building spaces. The majority of the artificial lighting, heating, and cooling systems are used to supplement nature's offering. Native vegetation and reclaimed water mitigate water use. The result is a comfortable, high-quality environment for the building occupants with lower energy and water requirements for the building owners.
