This paper presents results of a parametric study of the energy performance of a prototypical single-family ranch-style house. The DOE-2.1B computer program was used to analyze the variation in heating, cooling, and total energy requirements due to changes in the following fenestration characteristics: orientation, size, conductance, and shading coefficient. These parameters allow us to estimate the performance of hypothetical fenestration systems using advanced aperture materials as well as commercially available products. The work represents the initial phase of a study in which the influence of other residential parameters such as internal loads, infiltration levels, natural ventilation, use of night insulation, shade management, and overhangs will also be investigated. Climate sensitivity was established by considering results from Madison, Wisconsin, and Lake Charles, Louisiana. To simplify the analysis, multiple regression techniques were used to generate a simplified algebraic expression that relates energy use to the parameters varied. This representation could form the technical basis for simplified design tools for selecting optimal fenestration parameters.
