【 摘 要 】

This paper presents a framework for the development of early-design guidance to inform architects and policy-makers using parametric whole-building energy simulation. The emphasis of the study was to identify and assess the benefit of energy efficiency alternatives primarily focused on the building's thermal envelope. The energy efficiency alternatives included performance adjustments to the external glazing, wall, roof, floor properties. The Result indicated the glazing selection should look to achieve the highest thermal resistance (R-value) and best solar control (lowest shading co-efficient value) within budget. Ideally a solar control low-e IGU system could be installed. Solar control glazing also reduced the required development cooling capacity by ∼17%.
