Energy Efficiency Optimization on Sustainable Housing Modelling in Tegaldowo, Pekalongan, Central Java

Abstract

House is a place for human activities that has certain requirements to provide comfort for the occupants and have no significant impacts to the environment in order to achieve sustainability. Reducing annual energy consumption is one of the strategies to achieve the principle of sustainability in the housing model. Annual climatic conditions in Pekalongan Regency are classified as fluctuating due to geographical location in coastal areas with temperatures of 25°C at night and 31°-33°C during the day with fluctuations of air humidity ranging from 70-90%. Geographical conditions of Pekalongan Regency require comfort that have the potential to cause high energy use. The purpose of this research is to provide housing model that has efficient energy use in suburb area in Tegaldowo, Pekalongan, Central Java. The applied strategy is to optimization the potential of the local climate to provide comfort through passive designs such as building shape, openings, and orientation. Quantitative method is used by performing simulation on Sefaira based on ASHRAE standards in zone 2 (hot humid climate). Based on the simulation results, modifications made to the direction of the roof slope, building orientation, and openings in the facade have a significant impact in increasing the effectiveness of annual energy use in housing modeling in Tegaldowo.

Sustainable Housing Development in China: Does Financial Institutions Overcome the Risks and Challenges to Sustainable Housing?

“…Therefore, along with the other issues, the fulfillment of economic requirement is most crucial (Adabre et al, 2022). The second most crucial challenge is the fulfillment of environmental requirement (Susilo & Octarino, 2022). The material used for the construction has significant effect on the environment (Dawoud et al, 2020;Shurrab et al, 2019).…”
