International Code Council Takes Action on ASHRAE Proposals


International building codes may soon incorporate new requirements from ASHRAE standards, thanks to several recent proposals now under consideration.

ASHRAE has made several proposals to the International Code Council (ICC), and after a public review, final hearings for the code change proposals will take place May 21-22, 2007. If the proposals are accepted, they will be included in the 2007 code supplement.

“It is the governmental use of building codes and the conversion of standards into codes that derive the greatest benefit from the ASHRAE standards’ development process,” said Terry Townsend, ASHRAE president, at a meeting with ICC leadership, encouraging adoption of the proposals.

A proposal to include new ventilation rates from ANSI/ASHRAE Standard 62.1-2004, Ventilation for Acceptable Indoor Air Quality , was approved for inclusion in the International Mechanical Code (IMC). The change would lower zone ventilation in many zones, particularly those with high occupant density, and improve overall ventilation results in systems where zones with differing ventilation requirements are served by a common ventilation system.

“For many high-occupant-density zones (like classrooms and places of worship) these new rates reduce outdoor air intake requirements by 50% or more, compared to the IMC,” said Dennis Stanke, chair of the Standard 62.1 committee. “HVAC systems for these buildings can be designed with fewer air-conditioning tons and operated using less energy. Lower intake rates tend to reduce both first cost and operating cost.”

Four proposals written by ASHRAE’s Code Development Committee for ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings , and ANSI/ASHRAE Standard 90.2-2004, Energy-Efficient Design of Low-Rise Residential Buildings , were approved for inclusion in the International Energy Conservation Code.

• EC39: Lowers the solar heat gain coefficient requirements in residential buildings in Climate Zones 1 and 2 to 0.37 from 0.40. This requirement is consistent with Standard 90.2-2004.

• EC84: Adds a U-factor table to the code and add definitions for C-Factors, and F-Factors.

• EC98: Adds a requirement for hot-gas-bypass to the code.

• EC125: Revises exterior lighting control requirements.

Also related to its energy standard, ASHRAE plans to submit a public comment on a proposal to provide R-Value, U-Factor requirements and removal of the Standard 90.1 envelope section as a compliance method. ASHRAE opposes approval of proposal EC82 because it removes a partial reference to Standard 90.1.

Also approved was a proposal to make the IMC more consistent with ANSI/ASHRAE Standard 34-2004, Designation and Safety Classification of Refrigerants . The change would add new refrigerants for which the standard has given a designation and safety classification. The addition will facilitate use of these refrigerants.
