Review of Existing Energy Retrofit Decision Tools for Homeowners

20 September 2021 - Published by Deirdre Buist
As part of the Stronghouse project, our knowledge partners at the Robert Gordon University (RGU) have recently produced a detailed review of existing energy-retrofit tools for homeowners. We are proud to share this excellent analysis with our stakeholders across the North Sea Region.

Energy retrofit tools are considered by many countries as one of the strongest incentives to encourage homeowners to invest in energy renovation. These tools help homeowners to get an initial overview of suitable retrofit measures. Although a large number of energy retrofit tools have been developed to inspire and educate homeowners, energy renovation by individual homeowners is still lagging. The impact of current tools is insufficient as awareness and information issues remain one of main obstacles that hinder the uptake of energy retrofitting schemes.

Comprehensive analysis

The RGU research, carried out by Mohammad Seddiki, Amar Bennadji, Richard Laing and colleagues, extends the current knowledge by analysing the characteristics of 19 tools from 10 different countries. The selected tools were analysed in terms of energy calculation methods, features, generation and range of retrofit measures, evaluation criteria, and indications on financial support.

Highlight indications

In a nutshell, the review indicates that:

  • Most toolkits use empirical data-driven methods, pre-simulated databases, and normative calculation methods;

  • Few tools generate long-term integrated renovation packages;

  • Technological, social, and aesthetic aspects are rarely taken into consideration;

  • The generation of funding options varies between the existing tools;

  • Most toolkits do not suggest specific retrofit solutions adapted to traditional buildings;

  • Preferences of homeowners in terms of evaluation criteria are often neglected.
