Abstract

The abundance of solar light in tropical countries is the advantage of the utilization of solar energy. Increasingly expensive electricity forces buildings to use passive ventilation as building coolers. One of them is the use of the stack effect through the solar chimney. The absence of residential buildings that use the solar chimney as part of a passive ventilation system makes the need for prototypes for residential buildings. The application of solar chimney to homes in Jakarta is something new. Six types of the solar chimney have been tested on a prototype, one-story residential houses in Jakarta. The location was assumed to be in the densely populated area of South Jakarta. Wind velocity ambient data using Rubber locations. Using Ansys 16.0, simulations have been carried out, and solar chimney with double-full roof collector was able to induce a wind velocity of 0.41 m/s on average

Abstract

The engineering of building envelope aims is to achieve building energy efficiency which uses shading device to increase the shaded area. Also, to reduce heat gain by the building from solar radiation, this will reduce the energy load on the building. This paper aim to focuses on the deepening of technology of building envelope elements, and how the building envelope can control the thermal comfort as part of the indoor environment in a building that carries sustainability architecture. In conclusion, finally, reveal that the principles of passive design on building envelope have a great influence on the comfort level in the building. It is not possible to create a design that meets the thermal comfort requirements by emphasizing the design of building envelopes. The goal to be achieved in sustainable design is to minimize the use of the current design that takes much energy (almost14% world energy consumption) to address the issue of energy crisis lately.
