ASHRAE , Atlanta, published the 2007 version of ANSI/ASHRAE/IESNA Standard 90.1, Energy Standard for Buildings except Low-Rise Residential Buildings. The standard provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. The updated standard contains 47 changes to the 2004 standard through new requirements to lighting, facades, and mechanical systems.
Two of the addenda address air conditioning issues during the warmer months by enhancing the insulation and fenestration requirements for the building’s exterior. The standard also addresses reduction of electrical and cooling loads and thus electricity by allowing less power lighting. In addition, an addendum revised lighting allowances for retail displays because it allows more flexibility for designers and better reflects actual
Examples of the impact the new standards will have include; addendum AN will save about 18 trillion Btu of gas and oil annually, addendum G will save an estimated 1.05 Quads of cumulative primary energy by 2035, and addendum F will save and estimated 2.3 Quads of cumulative primary energy by 2035.
The cost of the I-P version of ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings, is $119 ($95, ASHRAE members). The SI version will be available later this spring.
