ASHRAE updates energy efficiency standard

ANSI/ASHRAE/IESNA Standard 90.1 gets a bit of makeover for 2007, adding efficiency requirements for lighting, façade and mechanical systems in buildings except low-rise residentials.

Energy reduction for lighting, fa%%CBOTTMDT%%ades, and mechanical systems is achievable through new requirements in the latest energy efficiency standard from ASHRAE and the Illuminating Engineering Society of North America . Exclusive of low-rise residentials, the 2007 version of ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings , provides minimum requirements for the energy-efficient design of buildings.
“One of the best ways to reduce building energy consumption is to reduce, or eliminate, the cooling or heating loads,” said Mick Schwedler, chair of the Standard 90.1 committee,. “By doing so, the systems installed in buildings become smaller and use less energy.”
The standard contains changes made through 47 addenda to the 2004 standard and addresses reduction of electrical and cooling loads, and thus electricity, by allowing less power for lighting. An addendum revised lighting allowances for retail displays, as it allows more flexibility for designers and better reflects actual retail lighting functions.
