Los Angeles takes the LEED

The Los Angeles Times reports:

L.A. panel approves ambitious green building plan

November 16, 2007

The Los Angeles Planning Commission on Thursday approved one of the most ambitious green building programs of any big city in the nation, requiring large new developments to be 15% more energy efficient. The new rules, which also restrict water use, aim to cut the city's emissions of greenhouse gases.Cities have no power over vehicle tailpipe emissions, which are ultimately controlled by the federal government. And power plants, another major source of greenhouse gases, are mostly regulated by state government, except in the case of cities that own utilities, such as Los Angeles.

Under the L.A. rules, new buildings with more than 50 units or 50,000 square feet of floor area would be required to meet national standards established by the U.S. Green Building Council, a Washington-based nonprofit organization that is working with cities across the country. The measure is expected to come before the City Council early next year.The standards -- known as Leadership in Energy and Environmental Design, or LEED -- would reduce the amount of energy used in large developments to well below what is required by California's building code, the strictest in the nation.

In addition to setting new rules for big developments, the city will establish a "green team" of experts from various departments -- including Planning, Building and Safety, and Water and Power -- to improve the environmental impact of the basic code for all buildings, including single-family homes and small commercial developments. The first recommended measures include wiring buildings for solar-energy systems, using high-efficiency heating and air conditioning units, and installing toilets and shower heads that use less water. In addition, half of demolition and construction waste would have to be recycled, and low-irrigation landscaping would be mandated for lots greater than 1,000 square feet.

The U.S. Green Building Council has a tiered system of measures: the basic LEED certification, which Los Angeles is planning to adopt for large buildings, and LEED silver, gold and platinum. For developers willing to submit their projects to the council for silver certification, the commission Thursday approved a measure to expedite permits that could save builders from two months to a year.
