The Top Ten Energy Efficiency Best Practices and Best Available Technologies Task Group (TOP TENs)

The TOP TENs Task Group showcases the best available energy efficiency technologies and practices in use by businesses today in participating countries. Task group members do so by developing two types of lists: Top Ten Best Available Technologies (BAT) and Top Ten Best Practices (BP).

The aim of the lists is to show to businesses and policy makers the practical and scalable energy savings solutions currently available and to support the accelerated uptake of innovative energy savings solutions.

The BAT and BP lists feature leading energy savings approaches and include information and case studies on the technology or practice, and where and how they are used. Examples of technological solutions highlighted in the inaugural lists include co-generation, use of heat pumps and recovery of industrial waste heat. Practices include ‘just-in-time’ and zero energy office building activities amongst others.


Recent developments

Technical experts from member countries have developed the initial TOP TENs methodologies which have been used to assess a wide range of energy savings approaches in the industrial and buildings sectors. Criteria for the methodologies include, for example: energy savings potential; reliability; payback period and level of innovation.

In June 2018, TOP TENs completed the second round of domestic BPs and BATs lists for the industry and buildings sectors. As next steps, it will focus on:

  • Completing the international lists of BPs and BATs for the industry and buildings sector.
  • Implementing a communication plan to establish brand awareness and catalyse greater application of the lists, which will support the deployment of TOP TENs featured technologies and practices.

The latest publications for this task group can be found on the Publications page.
