Abstract

A method of energy conservation could be used to reduce the energy consumption of a restaurant building. This lead to a cost benefit at last for the user whom implement this feature. Simpang Raya Restaurant in Surabaya is constructed to have east facing VIP room which was exposed by direct sunlight therefore creating a hot and humid temperature within the room. There are several ways to reduce energy consumption while increasing thermal comfort all at once. A retrofitting through Double Skin Facades (DSF) are expected to lower the temperature with a significant amount. Two types of DSF used in the simulation includes Stagnant air DSF which trap the air within the cavity gap and Multi-Storey DSF which have an air flow within the cavity gap. Through the simulation conducted using Computational Fluid Dynamics software, Multi-Storey DSF have a significant temperature reduction up to 4,85 oC. Multi- Storey DSF are able to reach the thermal comfort according to ASHRAE 55-2020 without the usage of air conditioner, which could save the operational cost for the restaurant building. Through the Cost-Benefit analysis, the restaurant could have the payback period within 8 month prior to the DSF installation and save up to Rp. 2.369.068.058 15th year benefit with the cost-benefit ratio at 11,00 prior installing DSF.
