This volume describes the definition of buildings and HVAC systems developed for the analysis of the impact of solar heating and cooling of buildings (SHACOB) on electric utilities. In addition, the computer simulation models and procedures for determining system performance and service area demand impact are reviewed. The computation of the change in utility demand patterns, as a function of geographic region and season, requires the analytic definition of a variety of building types and solar systems consistent with the physical information required to process the simulation code. The computations must be done for a reference set of buildings equipped with solar heating and cooling systems, and then the same set equipped with conventional HVAC systems in order to determine the differential impact. Within the residential sector, a reference set of buildings was identified which would be representative of single family (detached and attached), multi-family (low-rise and high-rise), and motel occupancies. Within the nonresidential sector, a reference set of buildings was selected which would be representative of office, mercantile (retail store and shopping center), educational (elementary and high school), hospital, and light industrial occupancies. The determination and calculation of specific numerical values required for the parameters input to the simulation code to compute building heating and cooling loads are discussed. For residential buildings, the TRNSYS code was used directly with modifications for solar heat gain through windows, infiltration of outside air, and latent heat gains. However, the simulation of the thermal response of the heavier construction of nonresidential structures and the behavior of secondary HVAC distribution systems required the more extensive thermal loads models provided by the AXCESS computer program.
