A Simple Cost-Benefit Estimation For Daylighting Design And Analysis During The Design Process

Arpan Bakshi, J. Alstan Jakubiec

Abstract: The increasing market demand for early design analysis has created a need for simulation-based decision making tools to evaluate the cost implications of daylight improvements. This study investigates the implications of a tool-based analysis approach for offices, the most typical commercial building type in the United States (US), with respect to internal gains and energy use. Prototype single zone daylight and thermal models were created based on ASHRAE 90.1-2007 climates in the United States and envelope parameters to provide results parallel to industry standards. Daylight analysis is used to evaluate fenestration parameters in cardinal orientations. The results are linked into a thermal analysis engine as schedules for shading and electric lighting use which reduces both end-use electrical consumption and peak cooling demand with related air distribution system size adjustments, amounting to
