Principles of low-energy houses applicable in North European countries and their applicability throughout the EU

Share this Post:

In this report the NorthPass project consortium has collected and written down the main principles of designing a very low energy house and identified the special challenges to be met in the Northern European countries. The focus is especially on the challenge of the cold climate: colder air temperature, less sun light during the winter etc. when compared to most of the Middle European conditions. The national regulations or existing criteria were not taken into account, hence the analysis was purely based on physics and existing technical solutions. The principles of the very low energy design can be summarized to: 1. Minimise losses and consumption, 2. Maximize gains and 3. Substitute the remaining energy need with renewable and environmental friendly energies. These principles are illustrated with some typical examples and existing solutions.

IEE NorthPass-project aims at overcoming barriers on the very low-energy house markets in cold climate, such as the lack of well-defined concepts adapted to the severe climate conditions, awareness of very low-energy houses, lack of products on the market and customer attitudes. This, and other NorthPass results reports can be uploaded from the project website www.northpass.eu
