Project Description

Investigation into Why Display Energy Certificate and Recommendation Report Non-Lodgement Occurred in the United Kingdom

The UK government introduced the Display Energy Certificate (DEC) as a statutory instrument:

To track energy consumption in publicly visited buildings
To be displayed prominently by public authority buildings
To be accompanied by a Recommendation Report (RR) of potential energy saving measures. However, Bruhns et al. (2011) and Hong and Steadman (2013) raised concerns over DEC non-lodgement of 20% and 50% respectively. Therefore, this award-winning D.Eng. research project investigates why DEC and RR non-lodgement occurred in the UK

Its objectives are:

To explore global Building Energy and Environmental Assessment Certification (BEEAC) tools
To determine the extent of non-lodgement and relevant trends in the dataset of UK central government and England and Wales local government DECs and RRs between 2008 and 2017
To determine insights into why DEC and RR non-lodgement has occurred in the UK and ways to address the issues based on responses from DEC Low Carbon Energy Assessors (LCEAs)
To determine insights into why DEC and RR non-lodgement occurred in the UK and the ways to address the issues based on building managers’ responses to the DEC LCEAs’ responses
To contribute knowledge about DEC and RR process-compliance and process-flaw mitigation

Its methods are:

The systematic review of 56 BEEAC tools used in 78 to 140 countries. This involves the meta-analysis of BEEAC tools to determine their underlying principle, good practice (how they can likely be enhanced), and the DEC and RR process-flow and process-flaws
The meta-analysis of 510 UK central government and 215,237 England and Wales local government DECs and RRs to determine the extent of non-lodgement and relevant trends in the dataset
The thematic analysis of interview responses from DEC LCEAs to determine insights into why non-lodgement has occurred and the ways to address the issues
The thematic analysis of building managers’ interview responses to determine their views on themes from the DEC LCEA interviews, insights into why non-lodgement has occurred, and ways to address the issues
Knowledge transfer by development of recommendations for DEC and RR process-compliance and process-flaw mitigation
