EBN reported last October on a California law requiring annual energy-use reporting for all nonresidential buildings. (Commercial owners will have to disclose energy use starting in 2010.) How far behind is a national law? Last week, a 648-page draft was released of the American Clean Energy and Security Act of 2009 (ACES) bill by House Representatives Henry A. Waxman (D-CA), chairman of the Energy and Commerce Committee, and Edward J. Markey (D-MA) chairman of the Energy and Environment Subcommittee. It's got a broad scope — promoting renewable energy, carbon capture and sequestration, low-carbon fuels, electric vehicles, and smart grids; increasing energy efficiency in buildings, appliances, transportation, and industry; decreasing emissions of heat-trapping pollutants; and protecting consumers and industry during the transitions. The building industry will be most interested in Subtitle A, Building Energy Efficiency Programs, under Title II, Energy Efficiency:

Subtitle A - Building Energy Efficiency Programs
• Sec. 201. Greater energy efficiency in building codes.
an excerpt: The applicable target for overall nationwide energy savings, compared to the 2006 IECC for residential buildings and ASHRAE Standard 90.1-2004 for commercial buildings, for the national model building energy codes and standards shall be 30 percent in editions of each model code or standard released after the date of enactment of the American Clean Energy and Security Act of 2009; 50 percent in editions of each model code or standard released after January 1, 2016. Any target set by the Secretary... shall be set at the maximum level of energy efficiency that is technologically feasible and life-cycle cost effective, and on a path to achieving net-zero-energy buildings. (There's a lot more language than this, and I'll be honest — I don't know what it means. If anybody wants to give it a read and report back in the comments, that would be great. As far as I can decipher, new buildings will be required to have 30% energy use reduction by 2010, and 50% in 2016, with new targets set every three years afterward.)
• Sec. 202. Building retrofit program.
an excerpt: The Administrator shall develop and implement, in consultation with the Secretary of Energy, standards for a national energy and environmental building retrofit policy for single-family and multi-family residences. The Secretary of Energy shall develop and implement, in consultation with the Administrator, standards for a national energy and environmental building retrofit policy for commercial buildings. The programs to implement the residential and commercial policies based on the standards developed under this section shall together be known as the Retrofit for Energy and Environmental Performance (REEP) program. The purpose of the REEP program is to facilitate the retrofitting of existing buildings across the United States to achieve maximum cost-effective energy efficiency improvements and significant improvements in water use and other environmental attributes. The REEP program shall utilize Federal personnel and resources as needed for development, design, program materials, administration, seed capital, and other activities and support. (Does this sound like the Environmental Service Corps?)
• Sec. 203. Energy efficient manufactured homes.
This is about mobile home upgrade replacement rebates.
• Sec. 204. Building energy performance labeling program.
an excerpt: The Administrator shall establish a building energy performance labeling program with broad applicability to the residential and commercial markets to enable and encourage knowledge about building energy performance by owners and occupants and to inform efforts to reduce energy consumption nationwide. The Administrator shall publish a final rule containing a measurement protocol and the corresponding requirements for applying that protocol. Such a rule shall define the minimum period for measurement of energy use by buildings of that type and other details for determining achieved performance... shall identify necessary data collection and record retention requirements...
