2911 -- Commercial Building Energy Performance Analysis Using Multiple Regression PDF

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.
