This paper defines parameters that characterize the statics and dynamics of a building. A static parameter is the familiar building loss coefficient that we can calculate using element-by-element addition or determine from building performance data by regression. The dynamic parameters are obtained from a natural generalization of the static parameters. These parameters thus share the same characteristics. In this paper we define eight parameters for a one-zone building and give the results from actual performance data, pointing out. extensions and applications. This method is referred to as BEVA (Building Element Vector Analysis).Units: Dual
