A simplified thermal response model

Abstract

The observed dynamic thermal response of intermittently occupied buildings can usually be described by one or two time constants. This suggests that much of the complexity in detailed computer thermal response models may not always be necessary. Simplified thermal response models may be adequate for many purposes, and ought to have cost advantages, both in setting up and run time. The paper describes the basis of a simplified microcomputer model of building thermal response. Model predictions of internal temperature variation in a working school are shown to agree well with observations. The model is intended for professional use and user interface is being developed in consultation with an architectural practice.
