ASHRAE, ACCA Issue Load Calculation Standard - ASHRAE 183
April 18, 2007 // Published as a news service by IHS
The standard, developed in conjunction with the Air Conditioning Contractors of America (ACCA), was published to establish minimum requirements for performing load calculations.
According to ASHRAE, the standard was designed to establish minimum requirements for building loads that are inclusive of as many procedural methods as possible while identifying core elements that impact heat loss and gains.
Requirements are non-prescriptive and are aimed at ensuring that developers of load calculation methodologies observe recognized good practices.
The specifics in undertaking a load are left to the discretion of the industry professional by their selection and application of load methodologies that meet the standard.
The need for ANSI/ASHRAE/ACCA 183-2007 was driven largely by demand from the code enforcement community.
Code references to the ASHRAE Handbook existed, making it the de facto standard, according to ASHRAE, which noted that the handbook was never intended to be a standard.
Proper load calculations are the first step in any design process, said Chris Wilkins, chair of the committee that wrote the standard.
