Adopting new technology and new solutions can make our society more efficient and more sustainable. Implementing a new energy labelling scheme for residential and commercial buildings can raise awareness about energy consumption and make buildings more energy-efficient.
Today all residential and commercial buildings for sale or rent must have an energy performance certificate showing the building's energy efficiency rating.
We have developed an energy labelling system for ENOVA with two main goals:
- Classification of buildings' energy efficiency (Class A, Class B, Class C, etc.).
- Offer building owners good ideas on energy efficiency measures that will improve their energy efficiency rating.
Based on Microsoft technology, the solution was developed through constructive, open cooperation between ENOVA, Multiconsult and EVRY. We are responsible for managing and further developing the energy labelling system to keep it viable in the future.
The energy labelling system is a web-based self-service solution with a flexible and user-friendly interface. The solution can be used by both building owners and experts, and based on the data entered by the user, the system will perform detailed energy performance calculations that will form the basis for the energy performance certificate.
The solution is also integrated with the Land Registry maintained by the Norwegian Mapping Authority so that users can find their own properties. The system calculates an energy rating according to a scale specified in separate regulations, and issues an energy performance certificate for each building.
The energy labelling system is available as an online self-service solution, and is intended to raise awareness about good energy efficiency solutions in existing buildings and to promote the construction of more highly energy-efficient buildings. Fortunately there is great potential for reducing Norway's total energy consumption in the future.
