Case study on Opportunities to Revise Energy Codes by Data Digitization Using a Smart Building Energy Audit Tool With Buildings in Hong Kong Howard Cheung, Tony W L Ho

Abstract

Building energy management is crucial to meet carbon neutrality targets between 2050 and 2060. Yet, building energy management standards and codes are struggling to be updated quickly due to misunderstanding from stakeholders outside the standard and code revision committees. This paper explores opportunities to clarify the misunderstanding through digitization of data collected from statuary submissions for these standards and codes of various buildings. 239 building energy audit cases in Hong Kong between 2019 and 2021 are digitized with a smart energy audit tool and analyzed. The results show not only opportunities to counterargue misunderstanding from the stakeholders on the impossibility to follow proposed standards, they also show new opportunities of new building energy management techniques to further reduce building energy use and to meet carbon neutrality targets.
