Green building performance matters: measure it correctly!
Green buildings are environmentally responsible through their life cycle- design, construction, operation & after deconstruction. Energy efficiency, though a significant component/ aspect of any green building, is not the only determining factor of a green building.
Sustainable site planning, water and waste management, use of low energy and environment -friendly materials, use of renewable energy systems and several other aspects have significant importance in any green building rating system.
Therefore, hypothetically speaking, even if a building meets the threshold level of energy efficiency as determined by a rating system, can still be rated under green building rating systems. Of late there has been much hue and cry about energy performance of green buildings that are rated.
