BENCHMARKING AND DATA ANALYSIS OF COMMERCIAL BUILDING ENERGY DATA WITH SPECIFIC REFERENCE TO OFFICE BUILDINGS IN SINGAPORE

Abstract

The Building and Construction Authority of Singapore has been publishing the BCA Building Energy Benchmarking Report (BEBR) since the year 2014. The BEBR aims to efficiently benchmark the energy consumption of buildings in Singapore to help building owners better understand how their building is performing and to strive to improve their energy efficiency.

This study focuses particularly on office buildings in Singapore. It investigates the data provided by BCA and aims to provide a deeper analysis on office building stock in Singapore, as well as to improve the overall benchmarking process.

To complement the data provided, case studies on the benchmarking process in the United States of America as well as the European Union have been used to identify key factors that we can learn from and adopt. Additionally, external data is used to provide a more in-depth study on the outliers that have been identified in the data.

The study finds that Singapore is still in the early stages of building energy benchmarking and there is much to learn from more established benchmarking policies. The data analysis could can also be improved to identify more parameters and trends in office building energy consumption.
