THE EFFECT OF SHADOW TO BUILDING ENVELOPS TOWARDS THERMAL PERFORMANCE IN APARTMENTS AT TROPICAL AREAS

Breeze Maringka & Darmawan Wisnu Utomo

ABSTRACT
In the era of energy, economizing is a principle issue to decrease global heating. High rise buildings need much energy, especially for apartments. In tropical climatic regions, heat and humidity are main problems in present thermal comfort. The easiest strategy to overcome them is installing Air Conditioning (AC); but it needs much energy and the impact is the environmental damage due to the unused gas. We Can seek various strategies for the solution to get better thermal comfort for high rise buildings; one of which is the design of shadowing for building envelops.
In general, apartments have more than one tower; therefore this research is aimed at knowing the impact of shadowing for building envelops either for building envelops themselves and also the design consequences and the consequences of shadowing upon the towers around. Facade design effects towards refrigeration load is researched by a computerized-simulation method (Ecotect software) and applied in two different apartment objects which are different in the typology of the block plan located in Surabaya city. The result is assumed that 50-70 % heat gain that causes highest refrigeration load comes from the internal gain and the shadowing design for building envelops which can cause space temperature description as big as 0.01-3°C.

Keywords : Tropical climates, Apartment building envelops, thermal performance, shadowing.
