Investigation of Energy Risk in Pre-Construction Stage: A Qualitative Approach

Abstract

The energy demand growth every year for existing building due to the natural lifecycle of the building performance. Systematic strategy in retrofitting is proven to revamp the energy building performance. However, the retrofitting process is facing several of unknown risk as early in pre-construction stage to achieve optimum energy efficiency design strategy. The risk requires strategic assessment to minimize the impact towards the efficiency level in retrofitting. This study aims to examine the risks and the potential impact towards design strategies by conducting a semi-structured interview from six internal stakeholders in the retrofit project. The result derived from the interview revealed that there are 13 of major risks involve in retrofit project and divided into planning stage and design stage. All the risks are proven to provide a potential impact towards energy efficiency design strategies.
