An energy efficient commercial building uses about 60% to 70% less energy than an average commercial building. Buildings can meet this target by improving building envelope design, efficient material, innovations in design and technologies. On the other hand, in addition to reduced energy cost they generate energy through renewable sources and other smart technologies.
Laboratories, universities, and research companies worldwide conduct zero energy commercial buildings research. These efforts are focused on defining zero energy -Efficient Buildings, Energy Use Assessment, Performance Metrics and Reference Buildings. The lessons learned from this research helps to understand the zero energy design, operation construction and evaluation of the current low energy commercial buildings. To achieve this goal it is important to engage commercial building constructors, architects, engineers operators, builders and owners from the public and private sectors to ensure these zero energy technologies are market-ready.
