An Overview of Barriers and Potential Solutions for Energy Renovation of Existing Buildings

Abstract

The renovation of existing buildings has recently gained recognition in the built environment as a viable alternative to the construction of new buildings. Building renovations have become a means of achieving sustainability through efficient and effective practices. However, the depth and rate of current energy renovations are far below what is needed to achieve this goal. Despite government efforts to promote building energy efficiency, various barriers hinder its implementation. This paper conducts a comprehensive analysis of these barriers, identifying and organizing them into distinct clusters: social, technical, financial, and institutional. The findings of this study will facilitate stakeholders' understanding of the barriers facing building renovation and inspire professionals to consider these barriers during the energy renovation of buildings. This approach can potentially reduce long-term energy consumption costs, greenhouse gas emissions, and the carbon footprint in the built environment.
