RESIDENTIAL LANDSCAPE ANALYSIS BASED ON ENERGY CONSERVATION

Abstract

The development of residential for public requires a wide landscape change resulting in microclimate change. The presence of residential has an impact on the increase in electricity need to provide comfort for dwellers, through the use of electric appliances such as Air Conditioner (AC), Efforts to cope with the increase of the need on electricity are done through two ways, i.e. by increasing electricity production or by reducing electricity consumption. The presence of vegetation can control microclimate by absorbing heat of sunrays and reflecting it, so that the temperature will be reduced (carpenter et al 1975). ln addition, the presence of trees as landscape elements affects the reduction of COz in the atmosphere. The process is done through photosynthesis and the deposition of COz in its biomass. The correct placement of trees can reduce the consumption of energy, which indirectly reduces COz emission from fossil-fueled power plant (Nowak 1994; McPherson 1998). This research tries to examine the relationship between the presences of trees in the use of electric energy for air conditioner in residential area, and to calculate the economic value. The research is conducted on Villa Duta and Yasmin residential. The analysis is done by using ArcView and ClTYgreen extension. The result shows that the presence of trees at Villa Duta is able to cut electric energy as much as Rp 47,852,500 per year or equal to 97,387,56 kWh, and is able to avoid carbon from power plant as much as 1,681,765.71 kg. The presence of trees at Yasmin is able to cut electric energy as much as Rp 89,276 ,175.28 per year or 551,817.56 kWh, with ability to avoid carbon from power plant as much as 9,519,451.04 kg per year. With annual expense for airconditioning as much as Rp 3,350,000 per year the savings at Villa Duta and Taman Yasmin are, respectively, 2.52o/o and O,88%.
