Property owners who want LEED certification for their buildings will have to provide ongoing energy and water usage figures

The data sharing is part of LEED 2009鈥檚 Minimum Program Requirements. The US Green 好色先生TV Council has said that is to inform building owners on how they are doing, and is 鈥渟imply a ground rule for entering the system鈥�.

Projects can comply by providing energy and water usage data annually; by recertifying on a two-year cycle; or by the owner allowing USGBC to access the data directly from the utility provider.

Kay Killman, sustainability associate at Hilson Moran, said: 鈥淭his move will make sure that developers are more diligent. This kind of approach forces them to think about energy and water usage more than they may have before.鈥�

Ricardo Moreira, director of XCO2 Energy, said the move was an excellent opportunity to gather data on buildings in use.

鈥淭his will allow for a closer assessment of the benefits of LEED for a large stock of certified buildings, as opposed to the much smaller samples used in existing research,鈥� Moreira said. 鈥淚t may also help to highlight the gap between energy modelling and real energy use.鈥�
