Energy Efficiency


The term, "Energy Efficiency" is understood as the achievement of a goal (i.e. a comfortable climate in the home) with minimum energy usage. Good energy efficiency exists when the ratio of usage to cost is close to 1. The BEI is primarily concerned with the improvement of energy efficient in energy use. The energy efficiency can be increased by either minimizing the energy needed (i.e. through better insulation of buildings) or by minimizing the energy lost by the conversion of energy (i.e. using the waste heat for heating). In March 2007, the EU agreed to increase energy efficiency by 20% until the year 2020; this ambitious goal is comprehensive of all energy usage and energy generation sectors.

Main research

  • Energy efficiency of buildings
  • Energy services

Further research:

  • Approaches to improve the energy efficiency of buildings, Evaluation of programs, policies, and measures to increase energy efficiency, Analysis of barriers and suggestions to overcome these, Cost comparison and the evaluation of innovative techniques, Studies on the behaviour of consumers
  • Development and assessment of financial instruments to increase energy efficiency, e.g. Contracting, funding, taxes, tax credits, and emissions trading (in particular in the household sector)
  • Preparation of information tools (e.g. energy performance certificates)
