Beefed up building energy-efficiency standards win approval in California

Beefed up building energy-efficiency standards win approval in California


Lynne Simnick | June 13, 2012

The California Energy Commission approved more-stringent energy efficiency standards for buildings. The measures will require hot-water pipes to be insulated and roofs to be able to accommodate photovoltaic panels. The regulations will cover construction of new residential and commercial buildings, as well as major retrofits.

The rules, which go into effect Jan. 1, 2014, would reduce wasted energy in heating, cooling, and lighting 25% over current standards for new homes, and about 30% for commercial structures, state officials estimated. The new measures set efficiency levels for whole house fans, upgraded windows, and improved wall insulation in residences.

Proposed changes for commercial buildings include solar-ready roofs, automatic controls that adjust lighting levels to sunlight, better refrigeration equipment, reflective roofing, and heat-filtering windows. The upgrades by law must be cost-efficient, and the Energy Commission estimated that the new standards would add $2,290 to the cost of a 2,200 sf home, but would yield $6,200 in energy-related savings over 30 years.

The new standards have the support of investor-owned utilities, environmental groups, local government building inspection officials, and high-tech businesses developing environmentally friendly building products. They also won grudging approval from the California Building Industry Assn., which represents 90% of home builders, and the California Business Properties Assn. Roofing manufacturers were opposed, arguing that the changes—particularly the installation of reflective roofs on commercial buildings—were based on insufficient financial data and would unnecessarily raise construction costs.
