Energy Cuts in Commercial Buildings


Detailed description of the Good Practice

Commercial buildings can use an enormous amount of energy to run lights, heating, ventilation and air conditioning. If this usage is not managed properly, power is wasted and unnecessary costs can mount up. A scheme run by the Energy Agency in Frankfurt, Germany, brought together owners and users of commercial property – along with investors planning new buildings – to take part in benchmarking exercises that analysed energy use. The information was used to plan efficiency savings that have produced dramatic reductions in energy usage.

Energy efficiency, energy saving

Objectives of the Good Practice

To optimize energy use in commercial buildings.

Participants of the Good Practice

  • The Energy Agency of Frankfurt
  • Property developers and owners
  • External consultans

Target group of the Good Practice

Commercial buildings

More Details of the Good Practice

The project identified ways to help commercial buildings cut back on their energy demands by, on average, 25 per cent - with payback on any costs being made up in less than five years. Between 10-15 per cent of total demand could be saved simply by optimizing the running time of equipment, without the need for any extra investment. The benchmarking exercise provided, for the first time, an accurate analysis of electricity demand in ten large office buildings in Frankfurt – in terms of how they use lighting, heating, ventilation, air conditioning, and office equipment. It revealed great differences in demand for power in each building and highlighted huge potential energy savings.
