Analysis on the Inter-Compensatory Problem in Green Building Rating System LEED-NC Based on Energy Saving
LEED-NC is a green building rating system for new construction developed by USGBC. In past 10 years, it has become the most famous assessment tool of the world and achieved the huge market success. In China, LEED and LEED-NC developed rapidly too. But, under the background of source shortage and global climate change, any green building rating system must place energy saving in important, even the first position. From energy saving, this paper analyzed unbalant environmental performance of LEED-NC certified projects because of inter-compensatory problem, especially in energy saving. Meanwhile, discussing post-occupancy evaluation of LEED-NC certified buildings, the paper verified many LEED-NC certified building did not save any energy. On this basis, paper pointed out new LEED-NC2009 meliorated the inter-compensatory problem. But, as a linear summation computational model, LEED-NC can not avoid inter-compensation absolutely. There is much room for USGBC to improve LEED-NC and China should be cautious to pursue LEED-NC.
