. >> clan cleveland, -- can cleveland, representing the building owners and managers association. we have been here from the beginning, when the mayor's office came to us and said, "let us quit something of the existing buildings task force that will measure the energy performance of existing buildings." we have laws now that deal with new construction. they are being built in a much more energy existing manner than the existing stock, which is probably 90% of buildings out there. we said fine. we will work with the department of the internment and the mayor's office. what you have before the amendments is a compromise of many hours of discussion and many deliberations with many stakeholders. i share supervisor chiu's interest in moving the bar forward here. we're already going to start putting a standing out there -- a standard out there that will probably be the most rigorous and aggressive for determining your energy consumption in commercial offices. but there are a couple of things i would propose. there is a difference between an energy audit and doing your benchmarking. ben
