Buildings Energy Efficiency Task Group (BEET)

The Buildings Energy Efficiency Task Group (BEET) is a collaborative platform for countries to research, inform and support the development and implementation of effective building energy efficiency polices, with a core focus on building rating systems and building codes.

The BEET contributes to work under the G20 Energy Efficiency Leading Programme.

Why do buildings matter for energy efficiency?

Recent developments

Over the past two years, the BEET has focused on three priority areas for improving the energy efficiency of buildings globally: reviewing the best approaches for energy efficiency ratings schemes for residential buildings, building energy code implementation and building energy performance metrics.

In 2017, the BEET published a report on Existing Building Energy Efficiency Renovation: International Review of Regulatory Policies (BEET6) which is the sixth in a series of studies produced by the task group. Energy policy makers today face the challenge of determining which set of policies are the most efective in signifcantly improving the energy efciency of existing buildings. BEET 6 addresses this question by providing an overview of key regulatory policies that have been used internationally to require improvements to existing commercial and residential buildings at various points, including renovation, refurbishment, retroft, alterations and additions.

The key messages in the BEET 6 report are:

  • Building energy codes can be applied to existing building renovations but other policies and programmes must also be implemented to achieve the deep energy savings sought by many governments.

  • Best practices are emerging in many countries that can be more widely adopted, both in the development of comprehensive policy targets and in the implementation of specifc building performance regulations.

  • Policies that appear to deliver the most signifcant activity in building energy renovations are the following:

    • Comprehensive improvement targets can set high, longer-term ambitions while continuously upgrading energy performance requirements. This can be done if the targets are supported by underlying policies and initiatives such as regulations, fnancing, and information campaigns targeting various stakeholders.

    • Disclosure of energy performance can potentially lead to major energy reductions if coupled with mandates tied to improving the performance of poorly performing buildings. However, since the mandated improvements can be politically challenging to implement and enforce, periodic disclosure of measured energy performance can provide the feedback loop required to understand the efectiveness of other policies.

    • Some role for a ‘renovation facilitator’ who can navigate diferent policies and stakeholder groups can be useful in efectively implementing deep renovations.

    • Linking fnancing and other supportive policies to deeper savings can transform markets and drive greater impacts. This can be achieved through tiered incentives where very deep renovations are rewarded.

  • Delivering large scale market changes appears to be most certain when legally binding measures can be tied to demonstrated improvement in building performance.

  • Further research is needed to understand the real impacts of more comprehensive policy packages that begin with ambitious targets, among other assessments.  

Previous reports

In partnership with the International Energy Agency, the Global Buildings Performance Network and the Pacific Northwest National Laboratory, the BEET has also produced two major reports and developed a web portal to facilitate collaboration among participating countries on building performance metrics and building codes. The web portal on building codes is a platform for sharing approaches to building code implementation that can accelerate improvements in energy performance and deliver greater cost savings for households and businesses. It is hosted by the Global Buildings Performance Network.

The International Review of Residential Building Energy Efficiency Rating Schemes report (BEET 5) compares energy efficiency rating residential schemes amongst BEET member countries and Part 2 distils the most successful elements of the different schemes into underlying principles for use by countries that have not yet developed ratings schemes, or in the case of Australia, are working with a number of jurisdictions to develop schemes with the intention of harmonising them over time.

The Building Energy Performance Metrics report (BEET 4) compares the historical efficiency trends in the buildings of major economies and provides illustrative data. It includes estimates of energy savings potential for the buildings sector and further highlights the need for smart efficiency policies to curb the growth of energy consumption in buildings.

The Delivering Energy Savings in Buildings report (BEET 3) demonstrates effective building energy code implementation is key to realising the massive energy savings potential of the building sector. The report offers a number of actions to increase compliance, including: implementing cost-effective building energy codes for all new construction and renovation; extending building rating, labelling, and disclosure policies to cover more building types; enforcing meaningful penalties for non-compliance; and implementing training and awareness programmes. Countries can strengthen these actions by sharing best practices and conducting joint capacity building training.
