Passive design implementation as sustainable development approach on vertical housing case study: Sentra Timur Residence

Abstract

Vertical housing development is a solution to solve the housing needs problem in Jakarta, which already had a land limitation issue. However, the development also contributes to environmental degradation. Building uses materials and energy in the development process, and when it operates. Most of energy use in Heating, Ventilating, and Air Conditioning (HVAC) to create physical comfort for user. Passive design strategies applied to maintain comfortable temperature in building such as building orientation, shading, and ventilation, so energy usage could be reduced. The purpose of this research was to analyse the implementation of passive design in vertical housing, as an approach to achieve sustainable building. Observation carried on Sentra Timur Residence, one of vertical housing in East Jakarta. This research used building data to create mass modelling to help analyse the passive design implementation. The results show that some passive design strategies are applied such as building orientation, shading, and ventilation, mainly in the housing unit. These strategies help to maintain thermal comfort inside the housing unit, so the users can feel comfort without using an air conditioner. It reduces energy usage in the building so negative impact on environment could be minimized.
