Description

In recent years, a number of developments have evolved which require improved methods for accurately predicting load profiles and energy requirements for the heating and cooling of buildings. Among these developments are modern architectural and construction practices, the increased number of energy sources used for controlling building environments, use of total energy systems, and use of computers for system control.

Currently accepted load calculation techniques also utilize transient heat transfer calculations. The equivalent temperature differential (BTD) method, for example, is based on transient considerations. The BTD method, while possibly more convenient for design purposes, is not flexible enough for energy calculations dealing with nonstandard outdoor solar and temperature conditions. The proposed ASHRAB calculation technique (Ref 1) utilizes transient heat transfer calculations to obtain response factors for structures. Therefore, thermal storage is accounted for directly.

In order to validate this proposed procedure, ASHRAB is sponsoring a two-phase program.
