Penerapan konsep bangunan ramah lingkungan melalui konstruksi green panel sebagai alternatif peningkatan kenyamanan dalam ruang

Abstract

Warmer air condition as the impact of global warming had effect to human building scale, i.e. the increasing of room temperature (T) and relative humidity (RtI). It causes an uncomfortable situation inside one building without using mechanical controlling temperature equipment, such as air conditioner (AC). Therefore, there is an alternative to improve indoor amenity by using green panel construction which appropriate with green building concept. The terminology of green panel ill this research was designated a panel made by an iron material, which has a function as secondary skin (second layer) that protect room inside from direct solar radiation, and also as an attempt for green building, or as a media for liana-plant growing. This research was conducted in Department of Landscape Architecture (DLA) Class Room and its corridor (Wing 13, Level VI). As a comparison location was General Laboratory which is managed by Department of Agronomy and Horticulture (DAH) located in the same wing and level, and DAH's seminar room in the same level, but in another wing. The effect of micro climate (T and RH) in DLA's Class Room were showed from the value of Temperature Humidity lndex (THI) around 25.7 to 30.6, with average 28.1 which is categorized as uncomfortable zone. The THI of DLA's Class Room were about 25.7-27.1 (in the morning), 25.8-29.3 (in the afternoon) and 25.8-30.6 (in the evening). Amenity level (THI value) of DLA's Class Room after green panel constructions were changed to 25.4 until 30.2 with average 27.7 which is still in uncomfortable category. However, THI value in the morning was in comfortable category. If green panel coverage's reach 100°h, the average THI value will decrease to comfortable category (THI 21.0-27.0). The result of SBE test shows that the SBE value has positive correlation with green panel construction. Four photos with the highest SBE's value were the photo after green panel constructed. This mean the construction of green panel could increase landscape beautification.
