Rising temperatures are turning indoor overheating into one of the primary challenges facing Europe’s building industry. New projects face a monumental task: creating sustainable homes that balance health, comfort and energy efficiency even during heatwaves.
So what’s the best way to prepare for rising temperatures while keeping energy costs low?
Building for balance.

These trends show why preventing overheating in homes has become essential in modern building design.
Large windows increase solar gain and can turn a dream home into a greenhouse during summer.
High levels of insulation, combined with insufficient airflow, can trap stale and polluted air and excess heat indoors.
Modern appliances and services generate constant heat that lingers in airtight homes.
Every occupant naturally emits body heat and moisture, tipping indoor climate out of balance.

In the face of exploding energy costs and increasingly long heatwaves, cooling has to be approached differently. By building for balance, cooling becomes a last resort. Instead of fighting heat with cold, ventilation helps prevent overheating from taking hold in the first place.
Our air ventilation solutions save energy and reduce costs every day, while elevating quality of life with every breath with controlled airflow, heat recovery and intelligent pre-tempering. Prepare your home for summer and get a voucher for 10% off our Zehnder filters.

The combination of a ventilation system with heat recovery and an air-to-air heat pump increases your home's efficiency through intelligent air pre‑tempering in both summer and winter.
A simple, silent "Plug & Play" installation offers a level of discretion conventional outdoor units can’t match.
