Potential Solutions to Common Barriers Experienced during the Delivery of Building Renovations for Improved Energy Performance: Literature Review and Case Study

To reduce the energy use and carbon emissions from buildings, there is a need to efficiently renovate existing buildings for improved energy performance. In response to this need, this study compares barriers and solutions for sustainable building renovation from the literature to a case study of barriers and solutions from a building renovation for improved energy performance. For example, the barrier of unforeseen conditions, affecting both cost and schedule performance, was addressed through a comprehensive building inspection guide to evaluate existing conditions and reduce risk. This barrier and solution appeared in both the literature and in the case study. Widespread adoption of the solutions presented in this study could provide more affordable renovations for improving building energy performance, and in doing so, help develop the market for building renovations to improve energy performance.
