ATLANTIC CITY — A special session inviting comments on revising an energy efficiency standard will take place at the ASHRAE Winter Meeting this month.

ATLANTIC CITY — A special session inviting comments on revising an energy efficiency standard will take place at the ASHRAE Winter Meeting in January.

An open discussion of ANSI/ASHRAE/ IESNA Standard 90.1-1999, Energy Standard for Buildings Except Low-Rise Residential Buildings, hosted by the Standard 901. Committee, will be held from 3:15-5 p.m. Sunday, January 13, in room 302 at the Atlantic City Convention Center. Registration for the ASHRAE meeting is not required to attend.

“This session allows anyone with questions about the use and application of the standard to talk directly with the people who wrote it – the committee members,” said Lawrence Spielvogel, chair of the 90.1 committee. “This session will make it easier for code officials, designers, owners and users to obtain more information about the standard without having to sit through lengthy committee meetings.”

In addition, the committee can get public input in drafting a revised standard to be published in 2004.

This standard was first developed in response to the energy crisis of the 1970s. The standard is published on a three-year cycle to coincide with the deadlines for adoption by major building code organizations.

Added Spielvogel: “The best way to simplify the standard for small and simple commercial buildings is to remove the complexity that is needed to address large and complex buildings. Our customers for most small buildings are not architects and engineers. They are overwhelmed by the standard the way it appears today.”

There will be a proposal for a separate new standard, limited to small commercial buildings up to a certain size, according to Spielvogel, since “more than 90% of all buildings (and about 50% of the square footage) covered by the standard are 25,000-sq.-ft. or smaller.”

Requirements in the proposed new small buildings standard will be taken from the complete standard, but the new standard will be “only a fraction of the size and complexity,” he said.

Meanwhile, ASHRAE is working on a proposed standard, 152P, Method of Test for Determining the Designated Seasonal Efficiencies of Residential Thermal Distribution Systems that closed for public review in September. The proposed standard is designed to facilitate annual energy calculations and heating and cooling equipment capacity calculations. It applies to single-family detached and attached residences with thermal distribution systems (duct systems, hydronic systems and electrical-wire distribution systems.)

Users of the proposed standard would provide a listing of all input data and their sources, indicating how the input parameters were determined. In addition to duct, the standard looks at parameters such as building climate, duct location, duct surface area, duct insulation, etc.
