Deep retrofit approaches: managing risks to minimise the energy performance gap (original) (raw)

2019

Abstract

Energy use in buildings remains a significant part of overall energy demand. Deep renovation projects, delivered at scale, remain a challenging task to achieve a lower carbon building stock. The complexity of building renovation is related to inherent characteristics of buildings which require distinct project management techniques. While there are now more projects focusing on achieving operational performance, there is still very little research on the management of the renovation and retrofit process itself – this paper aims to contribute to that literature. First, the policy context for renovation is briefly set out. Then five different approaches to building renovation are distinguished: whole house; fabric first; room-by-room, step-by-step, measure-by-measure. These categories provide the basis for analysis of the risk of there being a gap between designed and actual energy performance. In addition, ten stages of retrofit are set out, and three different types of risk at each ...
