Temperature reduction pinch analysis (TERPA): application of pinch analysis for tree planting targeting

Abstract

The global climate change as a result of rapid development is an important environmental problem nowadays. Concern about climate change are leading to the requirements to curb the Urban Heat Island (UHI) effect by different type of tree planting strategy. The electricity consumption in a building for cooling purpose increased tremendously due to UHI problem. To support the tree planting strategy as well as to save energy, target-oriented pinch analysis is recommended for identifying a systematic solution for energy planning and management problem. In this paper, a method known as Temperature Reduction Pinch Analysis (TERPA) is developed to examine the implication of dual objective – planting area utilization as well temperature reduction target in sustainable areal development which focused on building. TERPA is capable in rooftop planting targeting, vertical planting targeting as well as tree planting targeting through graphical representation. Rooftop planting and vertical planting is considered as zero land area consumption due to the fact that those planting is done within the building and no need extra land which tree planting in need of it. TERPA will be able to provide meaning and illustration to the effect of changing the target according to the future needs. A general methodology of TERPA is presented through the demonstration of a Malaysia’s case study. The result from this study is that a 17.24˚C temperature reduction can be achieved via proper type of planting targeting with the minimum land usage to give way for other facilities that are in need of land.
