The final search string included a combination of the general and specific search terms which was then adjusted for Science Direct. The relevant results which were downloaded into EndNote. The titles were reviewed to identify relevant papers and articles that could address the research topics. This resulted in a shortlist of 80 papers. Grey literature that was recommended in the first step was added to this list resulting in a shortlist of 88 papers and articles in total. The abstracts were then analysed, and additional papers sourced, to bring the final literature reviewed to 29. While many papers addressed residential energy efficiency retrofits specifically, they were more applicable to the following, than high level economywide benefits: -
technical studies (e.g., results of a specific intervention on individual households) non-residential or commercial buildings analysis of benefits or impacts on a very small sample size of homes modelled and predicted outcomes of potential EE interventions and a focus on existing and proposing new modelling methods (analysis and critique) analysis of homeowner decision-making via qualitative surveys and studies (e.g., motivations, attitudes, participation rates etc) quantification of energy and greenhouse gas savings specific demographics such as low-income households, social housing, rental housing, programs addressing fuel poverty etc.
3.1.3 Literature Review The shortlisted literature was then reviewed to address the research questions and gather evidence, as reported herein. Full details of the literature review are provided in the accompanying report Pathways to Scale: Evidence of environmental, social, and economic benefits of large-scale residential retrofits.
Home Upgrade Modelling Modelling was used to explore the benefits to be obtained from various retrofit packages in three priority location. The modelling aimed to address the following research questions: 1. What is the thermal performance of common housing types in New South Wales, Victoria, and Western Australia, as they were built in the early 2000’s (prior to the NCC 2010 6-star NatHERS rating requirement)? 2. How can this thermal performance be enhanced through retrofitting strategies, including floor, roof, and external wall insulation, diminishing leachability, energysaving appliances, solar PV and storage systems, lighting system?
