Drivers for building retrofitting practice: A systematic review

Retrofitting an existing building offers a significant opportunity to improve its performance to solve the problems associated with energy consumption, occupant thermal discomfort, and cost of operation in the building. It is essential to understand what drives the stakeholders, policymakers, and decision-makers in the practices of building retrofitting. Therefore, this study aims to identify the factors motivating stakeholders and house owners to practice retrofitting. This study is based on a systematic review of the literature published in peer-reviewed journals. Scopus and Web of Science were used as scientific databases to find relevant papers. The findings revealed that high energy costs, increased occupant comfort, to maintain or improve the property market/rental value, financial incentives, suitable awareness and attraction to modern technology are some drivers for building retrofitting. This study will help policymakers and advocates better understand the drivers for retrofitting existing buildings and will help to encourage the practice.
