Ventilation in Norway
Norway's TEK17 regulations and extreme cold climate make high-efficiency heat recovery ventilation critical for all building types, from coastal homes to mountain cabins.
Why energy recovery ventilation matters in Norway
Norway's climate ranges from maritime on the coast to continental and arctic in the interior and north. Winter temperatures can drop to -30°C or below in inland areas, making heat recovery ventilation absolutely critical. The extreme temperature differential means ERV units with 90%+ recovery rates can save thousands of kWh per year. Coastal areas face additional challenges with high humidity and salt air, requiring robust, corrosion-resistant units.
Local Standards & Compliance
Norway's Technical Building Regulations (TEK17) require balanced mechanical ventilation with heat recovery in all new buildings. Minimum heat recovery efficiency of 80% is mandated, though most projects specify 90%+ to meet the stringent energy frame requirements. The passive house standard (NS 3700) is widely adopted, pushing ERV efficiency requirements even higher. Enova provides grants for energy-efficient ventilation upgrades in existing buildings.
