Abstract

In Denmark, government institutions are subject to a circular (CIR no. 27 of 19 April 2005) to improve energy performance of buildings and enhance energy efficient behaviour, including purchase of goods and appliances. A dialogue between the governmental energy authorities, municipalities and regions has been initiated aiming at extending the regulation to all public institutions.

The potential for electricity savings in public institutions has been estimated to 1,2 TWh annually, or 30 %. The new circular aims at utilising this potential. 80 % will be achieved by efficient lighting, ventilation, IT and server equipment.

Another potential exists in heat savings. Most public buildings are already well managed, due to mandatory certificates that outline measures to improve energy performance.

The circular includes requirements with regard to:

organisation of energy management
energy efficient procurement policy
implementation of projects (investments) with a pay-back time of 5 years or less
cost effective maintenance and renovation of buildings
energy sound behaviour of employees

An analysis has been carried out in 2006 to stipulate an expected cash flow from such investment in energy efficiency improvements with a pay-back time until 5 years. The result of the analysis shows that from a 10 years perspective, it seems highly viable to introduce this part of the governmental circular to municipalities and regions.
