ARLINGTON, Va. - The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) has announced an American National Standards Institute (ANSI) public review period for its standard for Residential HVAC System Zoning. This standard provides the step-by-step procedures for the design of optimum zoning in residential structures. The public review period will close on July 4, 2011.

This proposed standard was created for mechanical and HVAC system designers and addresses the unique requirements of zoning design that include:

• Zonal load calculations.

• Zoning strategies and protocols (diversity issues; multi-level construction, diverse floor plans; winter/summer room and zone cfm variations; etc.).

• Zoned systems types/attributes (multiple furnaces or refrigeration cycle units, central heating-cooling with VAV dampers, split coil refrigeration cycle with multiple indoor coils).

• Controls and control strategies (VAV bypass air; VAV damper sizing; multi- or variable-speed; airflow management).

• Zonal duct design elements, as well as supply and return grille selection (constant volume vs. VAV).

This proposed standard is referenced as BSR/ACCA 11 Manual Zr-201x, and can be downloaded at www.acca.org/industry/ansi-standards/under-review. Comments must be submitted using the ACCA response form, by 11:59 p.m. EDT on July 4, 2011.
