TEK17 & energy standards
TEK17 and other energy-efficiency standards — building an A energy-efficiency class house.
TEK17 — Norwegian energy standard
In 2017 Norwegian Husbanken institution enacted requirements for new buildings and houses — TEK17. This is one of the strictest building requirements in Europe and the whole world. TEK17 standard narrows the gap between passive houses — NS3700 (Norwegian passive house standard) — and standard houses.
The main requirements for TEK17 are low U-values of house constructions and air-tightness of the structure.
| Construction | Max U-value, W/m²K |
|---|---|
| Floor construction | 0,15 |
| Outside wall | 0,18 |
| Roof | 0,13 |
| Windows and doors (with frame) | 0,8 |
This way Norwegian authorities charge new buildings to be energy-efficient and the country is leading in the world according to high standards for buildings.
Our houses at the moment easily reach such energy-efficiency requirements and Ekobustas is always learning and doing its best to keep up our production with the newest standards and highest requirements for buildings.
