This project, “International Review of Residential Building Energy Efficiency Rating Schemes”, is the fifth project in a series of work conducted through the Building Energy Efficiency Taskgroup (BEET), under the International Partnership for Energy Efficiency Cooperation (IPEEC). This project report presents key governance and administrative considerations in the design of energy efficiency rating schemes, available information on the cost-effectiveness and market impact of rating schemes, barriers to uptake of schemes and lessons learned from the implementation of schemes. The value of this report is to combine findings from the literature with findings from interviews with scheme operators, in order to highlight tacit and undocumented information. Interview responses were coded according to categories related to the project objectives. Findings from the interviews were then compared to conclusions from the literature.
Conclusions are drawn on the reports process and methodology as well as the findings themselves.
1. The methodology of stakeholder identification, briefing paper, interviews/survey, coding and comparison to literature, was well suited to the objectives of this project and could be replicated in future work. However, it should be noted that the task of finding appropriate people to interview was often difficult and time consuming.
2. In general, the findings that emerged from the interviews with scheme managers correspond with the body of literature. Notable points from the interview that are either different to the prevailing literature or received different emphasis than in the literature include:
o The importance of establishing long term goals and objectives for the scheme and maintain consistency in these over time.
o Consideration of the scheme as one component of a broader framework of energy efficiency activities.
o Significant under-resourcing of quality assurance and review processes.
o Recognition of, and engagement with, the full supply chain regarding how the scheme will affect them and the intended outcomes from the scheme.
