Abstract

Cities are facing a challenge with the steady increase in energy consumption for buildings. This study aims to analyse the energy consumption and payback period of energy-efficient strategy implementation in glass type options. The energy-efficient strategy in the glass options is chosen since it affects the energy consumption the most. A study on the payback period needs to be conducted since purchasing high-performance glass materials increase the building capital cost and become a consideration for decision-maker. This study tested 5 variations, including single and double glass windows and incorporating 5 types of glass materials with various solar transmittance properties. The energy consumption then is calculated using energy simulation software OpenStudio using Jakarta weather data. The payback period is calculated to find out the length of time the energy cost saving can recoup the additional capital cost needs to purchase better thermal performance glass. The result shows that the double glass windows with low solar transmittance value reduce the energy consumption for cooling the most. Thus, cheaper glass material with similar solar transmittance value reaches the payback period fastest.

Abstract

Energy-efficient residential provision is an essential concern for the present and future city development. Currently, the residential buildings contribute approximately 37.5% to significant energy consumption and carbon emissions, which mainly used for cooling. This research aims to study the house layout arrangement to minimise cooling loads and further reduce energy consumption. Energy efficiency analysis is performed by comparing the cooling load and total energy consumption from variations of the hypothetical design of detached or semi-detached housing layouts commonly built in Indonesia. The calculation of cooling loads and energy consumption is performed by simulation in Energy Plus 8.4 with Jakarta weather data. The results show that the arrangement of the house layout may reduce the cooling load up to 24%. The total conditioned wall area that varies due to the variations of house layouts are found to affect the cooling loads.
