Considering that buildings are the primary consumer of energy many progressive organizations are pursuing a Net-Zero Energy goal for their facilities.
This aggressive goal can be accomplished by significantly reducing energy use through the incorporation of energy-efficient strategies into the design, construction, and operation of new buildings and commencing retrofits to improve the efficiency of existing buildings.
The concept of a Net Zero Energy Building, i.e., “a building that produces as much energy as it uses over the course of a year”, has recently evolved from research to reality. There are however, currently only a few buildings that meet the criteria to be called “Net-Zero Energy”. As a result of advanced 3D Energy and Daylight Modeling, improvements in construction technology, building controls, and renewable energy systems, the design and construction of Net-Zero Energy buildings has become more practical.
