Description

Regression analysis defines algebraic expressions that can be used to study the effects of various configurational parameters on building energy performance. The DOE-2.1B energy-analysis simulation program was used in conjunction with prototypical building modules to generate a large data base for five geographic locations. Configurational variables parameterized included orientation, wall and roof conductance, glazing properties of windows and skylights (area, U-value, shading coefficient, visible transmittance, well depth), and installed lighting power. Incremental effects due to external shading (overhangs) and daylighting were also examined. A constant volume variable temperature secondary HVAC system was attached to each zone in the model, and the individual zone coil loads were used as a basis for showing the versatility of the regression techniques. The modular concept permits generalization of the results to buildings of arbitrary floor/glazing areas, and the resulting regression expression conveniently categorizes those components of importance in building energy use.
