Abstract: In Taiwan, the average of convenient store's Energy Use Intensity (EUI) is high at a 1501 (kWh/m2/year) which is 3 times higher than department stores, 7times higher than central air conditioning office buildings and 38times higher than housing due to operational hours, internal loads and a poorly designed building envelope. Unexpectedly, communities use convenience stores as thermal comfort refuges during summer. This study utilised a dataset of 251 convenience stores in Taiwan from the largest leading retailer to obtain data on the physical, construction elements, energy use and siting of convenience stores. Sample analysis results analysed the architectural features and main locations, urban setting of the convenience store for a base case design. The dynamic software IES-VE (2016) is used to simulate different envelope improvement techniques to understand cooling demand and indoor thermal performance in relation to an urban setting. The dataset energy loads were used to validate the simulation results. The simulation results show that the most efficient building envelope improvement type is an insulation roof with shading. It saves 17% of cooling load in arterial roads while saving up to 18% of cooling load in residential areas.
