Bridging the Information Gap on Energy Efficiency in Buildings

Energy efficiency offers one of the quickest and most cost-effective options to reduce energy consumption and mitigate climate change. There are various technologies and policy options to advance building energy efficiency, for example. However, this information is not available in an accessible and cohesive format.

To overcome this challenge, the bigEE project aims to bridge the information gap by summarizing leading knowledge and presenting comprehensive, independent and high-quality information on building energy efficiency. The project also aims to support decision-making and implementation.

The outcome of the project is an international internet-based knowledge platform for energy efficiency in buildings, building-related technologies and energy consuming appliances. The platform will provide information on:

  • technical solutions
  • energy efficiency potentials
  • cost-effectiveness of energy efficient buildings
  • policy instruments
  • good practice

bigEE focuses on decision-makers including private and public sector investors, policy makers and political leaders. The information will be presented in a manner that meets the practical needs of these target groups. Information will also be tailored to conditions and needs in different regions of the world. To achieve these aims bigEE is based upon a network of institutions in a number of countries. These project partners will collect and actively disseminate information. The first bigEE partner countries are China and South Africa. India and Mexico could become further prospective partner countries.

The CSCP developed technical and policy case studies for selected home appliances, including solar water heaters and cooking stoves. The CSCP also delivered capacity building workshops and develop targeted information brochures to raise awareness and communicate key messages to policy makers, investors, property owners and developers.


bigEE is an international initiative developed by energy and climate related technical, policy, and public research organisations in several countries. The Wuppertal Institute for Climate, Environment and Energy (WI) is responsible for overall project coordination. Partners include the Beijing CSUS-IBR Eco Technology Co. Ltd. and SANEDI. Financial support for the project was provided by the German Federal Ministry for the Environment, Nature Conservation and Nuclear Safety, under the German International Climate Protection Initiative.
