Continuous Maintenance of Standards Benefits Both Private and Public Sector

ASHRAE to Lead Open Session on Overview of Standard 90.1

New York, Oct 03, 2002

The voluntary standardization process in the United States monitors, updates and improves standards, and helps the government fulfill its mandate to ensure public safety and health. American National Standards Institute (ANSI)-accredited standards developers keep American National Standards current and relevant by means of timely revision or reaffirmation, and some are maintained under a process of continuous maintenance by accredited standards developers. The public- and private- sector work together to employ the best and most current standards in their appropriate applications.

In July of this year, the United States Department of Energy (DOE) determined that the 1999 edition of ANSI/ASHRAE/IESNA Standard 90.1-2001, "Energy Efficient Design of New Buildings Except Low-Rise Residential Buildings" would achieve greater energy efficiency in buildings (except low-rise residential buildings) than the 1989 edition. As a result of this positive determination, all states have two years to adopt Standard 90.1-1999 or upgrade their existing commercial building codes to meet or exceed its requirements. The standard now applies to all new commercial buildings, and all major remodeling or renovation of existing commercial buildings.

Standard 90.1 is maintained by ANSI member and accredited standards developer American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and was cosponsored by the Illuminating Engineering Society of North America (IESNA). It is registered under the Continuous Maintenance option (per ANSI Procedures) and is scheduled to be published in its entirety every three years. Current efforts to improve Standard 90.1-2001 will be presented in an open session at ASHRAE's 2003 Winter Meeting. The session, to be chaired by Graham Hunter, will also allow users of the standard to provide feedback and suggestions directly to the 90.1 committee.

"With the DOE ruling, more and more states will either adopt energy codes that reference ASHRAE Standard 90.1-1999, or the subsequent 90.1-2001, or revise their codes to change the reference from the 1989 standard to the new ones," said Hunter. "As always, [we] are prepared to discuss and encourage user's suggestions for improving the standard."

According to ASHRAE, Standard 90.1 is at the core of energy codes throughout the world. Standard 90.1 provides for the minimum energy-efficient requirements for the design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings. It also sets up criteria for determining compliance with these requirements.

While currently working from the 1999 version, the DOE has initiated an analysis of the 2001 edition to make a determination as to whether it will improve energy efficiency beyond the 1999 edition. A positive determination would require each state to review and update the energy efficiency provisions of its commercial building code to meet or exceed this edition.

Registration for the ASHRAE meeting is not required to attend. The session will be held Sunday, Jan. 26, 2003, at the Palmer House Hilton, Chicago. ASHRAE's Winter Meeting will take place Jan. 25-29 in Chicago. The 90.1 session will take place after the technical program is completed on Sunday and before the start of the ASHRAE co-sponsored International Air-Conditioning, Heating, Refrigerating Exposition, Jan. 27-29.

ASHRAE, founded in 1894, is an international organization of 55,000 persons. Its sole objective is to advance through research, standards writing, publishing and continuing education the arts and sciences of heating, ventilation, air conditioning and refrigeration to serve the evolving needs of the public.
