Requirements for existing buildings

The requirements for new buildings will also apply to major renovations, major renovations being defined locally by the municipalities, although defined by the guideline as more than 50% of the building area. New requirements will apply for new or repaired areas when there is a change of use, repair or extension, only to the affected parts.

Control of the regulation is the responsibility of the municipality where the building is located. This will mainly be an administrative check, to ensure all QA/QC papers have been completed and reports produced. There are proposals to reintroduce technical checks and surveys at the building site by a third party.

Certification of buildings

Proposed changes to the Energy Act on requirements regarding the certification of buildings have been presented by the Government at a public inquiry. The regulation will follow shortly, once the changes to the Act have been approved by the Parliament. The main comments resulting from the public inquiry are related to: › Proposed self assessment by building owner › Independence of the assessors. The Norwegian Government opted for self assessment

› Authorisation of experts. It is proposed that the assessors will self- assess their competence without any formal authorisation

› The proposed cut off point of the calculations for the certificate was the net energy demand, corrected for the energy demand from heat pumps and solar systems, not including other technical equipment for heating and cooling. The revised proposal of 18.06.2008 suggests a rating based on delivered energy.

Inspection of boilers and air conditioning

Proposed changes to the requirements of the Energy Act regarding the inspection of boilers and inspection of air conditioning systems have also been presented by the Government at a public inquiry. It is proposed to coordinate the new proposals with existing inspection schemes for boilers and air conditioners, where professional societies cater for training and certification.

For boilers the main changes will be enhancing a voluntarily process but, to make it mandatory for larger boilers >20 kW. For Air Conditioners there are proposed schemes based upon new regulations from the Ministry of Environment (f-gas), in addition to voluntarily schemes. The main change here is to enhance the schemes and to make them mandatory schemes, including companies that have service agreements.

Inspection reports must be registered in a central register using the web based tool for self assessment of energy performance in buildings (EMS) Energy Marking System.

3 > Future planning

It is expected that a scheme for the certification of buildings (new buildings, as well as existing buildings for sale or rent) and the inspection of boilers and air conditioning systems will be presented by the Government in 2008. This could become mandatory from 2009 for some building categories.

Based upon outlines and proposed changes to the Energy Act, NVE has outlined a system for self assessment, written a technical specification for
