The recent IPCC report emphasises the devastating impacts of climate change and calls for urgent action. The building sector must play a central role in mitigating global energy consumption. The GBPN’s research shows that by 2050, it is possible for the building sector to consume 30% less energy than it does today, even with the expected growth in population, floor space and comfort (Buildings For Our Future
, GBPN, 2013). To achieve this, the GBPN proposes a “deep path” for closing the energy and emissions gap in the building sector, requiring a 70% reduction in energy consumption in existing buildings. Specifically in the European Union (EU) and in the United States (U.S), the largest potential for energy savings lies in the renovation of the residential building stock. Therefore, it is urgent that deep energy efficiency renovation policies and supporting programmes become standard practice.
What key elements must progressive energy renovation policies address to reach to these goals? What can we learn from current best practice policies in the EU and in the US? Are they ambitious enough? To help answer these questions, the GBPN, with the support of a panel of international experts in the field, identified fourteen criteria
that define the key elements of a state-of-the-art policy package and scored the selected best practice policy packages against these. The outcome of the research captures the performance of the current best practices, enables their comparison and provides insight into what needs to be realised to accelerate more and deeper renovation policies.
A number of key findings have emerged from the research:
1. Energy renovation policy is an emerging field and there is scope for further progress. The tool shows elements where positive steps have been taken and where countries and states can learn from these actions.
2. The countries and states that were successful in reducing all consumption indicators were found to have holistic policy packages in place that address all aspects of the renovation process.
3. There is no such thing as an overall “best” policy package and all countries and states can benefit from best practice sharing.
4. Financial mechanisms need to be locally adapted and linked to broader national renovation strategies. National incentives and taxation mechanisms are widely used in the European countries whereas utility-funded and market based mechanisms are used in American states.
5. Among the current best practice renovation policies, there is a general absence of clear and ambitious targets for the renovation of the existing building stock.
The online Policy Tool
allows interactive visualisation of the scoring of the twelve best practice policy packages under each criterion. The tool also provides detailed information
about each jurisdiction and allows to generate graphs
based on time series data normalised of energy performance indicators in the respective countries/regions.
