Project Details


Background: The study “Energy savings in existing and new houses” made by DTU identifies a large po-tential for energy savings in houses today and points out construction elements to target.
In relation to this a demonstration project would be useful, that shows what is obtainable in practice on site, also cost-benefit wise, when dealing with the challenges of an existing house. Energimærkningsordningen has expressed interest in the project and manage a database with houses certified since 1997. They have found that the improvements suggested in the reports are often not carried out by the owners even though the payback time is short compared to the lifetime of the house. Via this database a “typical” house that represents a segment with po-tential for energy savings can be identified. Energimærkningsordningens secretariat has iden-tified villas before 1950 to be the most rewarding segment to approach for energy savings. To get the maximum benefit from the project, in regards to the ongoing political work, a pre-liminary result should be ready by the beginning of 2005.

Project Goal: The goal of this project is to:
• Demonstrate and document energy savings obtained by renovating a typical villa built be-fore 1950.

• Document energy savings and the cost of an energy renovation of the villa
(divided into preparation cost, documentation cost and building cost).
• Compare achieved savings to expected calculated savings
• Test of market response.
(Since the target group is defined very clearly by the database a direct marketing effort could be carried out with the results. This would reveal how large a hit-rate you can obtain by having the specific results that people can relate to.)
