A FRAMEWORK FOR ESTIMATING THE POTENTIAL ENERGY SAVINGS OF NATURAL VENTILATION RETROFITS FOR CALIFORNIA COMMERCIAL BUILDINGS

This paper proposes an approach for estimating the potential energy savings of retrofitting existing commercial buildings in California for natural ventilation. 308 baseline commercial building models are developed in EnergyPlus based on a characterization of the existing California commercial building stock. Each baseline model and five retrofit options are simulated in the 16 California Climate Zones using TMY3 weather files and energy savings are calculated. Building weights are developed and applied to expand the estimated energy savings to the statewide level. Based on the findings, recommendations will be made to assist policy makers, building designers and owners in making informed decisions regarding the efficacy of natural ventilation retrofits.
