Energy-Efficient Measures and Life Cycle Costing of a Residential Building in Hong Kong

Abstract

Energy simulations have been carried out for a residential block of flats. Energy-efficient measures such as using tinted and reflective glass, external shading and wall insulation have been studied. Life cycle cost analysis has been applied to these measures to find out the cost effectiveness. Discounting technique has been used to calculate the present value of energy cost over a life cycle of 15 years. This paper presents the findings and discusses the implications.
