| Abstract: | The construction industry is a major source of energy consumption, and the exploration of building energy-saving measures has been ongoing. In order to encourage the development of energy-efficient buildings, the voluntary environmental assessment program BEAM Plus is widely used in Hong Kong. However, BEAM Plus only gives credits for various energy efficiency options without explaining their priority. This research investigates the priority of various energy-saving options and their attractiveness to developers and designers in terms of energy saving and economic efficiency. A representative office building determined after extensive investigations was used as a baseline building in Hong Kong. The determination of the energy saving strategy was based on the option of earning credit in the BEAM Plus NB v2.0 energy use category. EnergyPlus simulations were used to determine the energy performance of various strategies based upon realistic operating. The initial costs required to implement various energy-saving strategies were ascertained by an detailed market survey and regression analysis. The reduction in CO2 emissions from the conversion of annual energy consumption and the credits earned served as benefits. The initial cost of the additional investment was taken as the cost. The widely used cost benefit ratio was used as an indicator to measure the priority of various energy-saving strategies. It could be found that the reduction of the window-to-wall ratio, shading coefficient and lighting power density have the highest priority due to the lower energy consumption and investment. The design of overhangs and green wall does not have economic benefits and the ability to earn high credit in office buildings. |
