Abstract

This study focuses on measuring the shading effect of surrounding buildings on the thermal performance of office buildings in Jakarta. It is compared with the shading effect of shading devices to optimize its use. This study uses EnergyPlus program to simulate a hypothetical 3x3block. The results showed that the H/W ratio has greater influence on building thermal performance than the surrounding building envelopes. With H/W ratio 2,7, the shading effect of surrounding buildings will be equivalent to 1,2m shading with an effective shadow angle of more than 360. For example, in a 10 floor building, the use of 1,2m shading is not required until the 8th floor based on the shadow angle in H/W ratio 2,7. At a smaller angle, the shading effect of surrounding buildings will be equal to the shading effect of shading devices with a width of less than 1,2m.

Abstract

Several strategies in reducing external heat gain sometimes have an impact on limited access to daylight in buildings. Therefore, an integrated study is needed between thermal and daylight performance of the building. This research focuses on building modeling and simulation on one of the buildings at UIN Walisongo Semarang to see these two parameters based on Standard Nasional Indonesia. The thermal performance through OTTV value is simulated using EnergyPlus, while the building daylight is simulated using Dialux. The existing condition showed that the thermal performance is not fully integrated with the building natural lighting. Further simulation is needed through the building envelope engineering. The results showed that the entire room has met the standard of natural lighting while maintaining the OTTV value according to the standard. This condition is the optimal point which represents the integration between thermal and daylight performance of the building.
