Mechanical ventilation and HVAC: A guide to a healthy and energy-efficient home

A modern, energy-efficient home is like a thermos flask: its envelope is very tight to minimize heat loss. This is great for energy savings, but it creates a challenge for indoor air. In tight buildings, air does not exchange naturally, which means that moisture, carbon dioxide and pollutants remain inside. Therefore, a controlled and efficient ventilation system is absolutely essential in modern construction.

In new buildings, the solution is almost invariably mechanical supply and exhaust ventilation with heat recovery (LTO). The system continuously removes used, humid air from wet rooms and the kitchen, and replaces it with fresh, filtered outdoor air into the living areas. As its name suggests, it recovers up to 80% of the heat energy in the exhaust air and transfers it to the supply air. This not only ensures healthy and pleasant indoor air, but also saves significantly on heating costs. It is an investment that protects both the health of the residents and the building's structures.

• Mechanical ventilation with heat recovery (IV-LTO) is standard in modern construction and ensures healthy indoor air.
• Heat recovery (LTO) saves significantly on heating costs – up to over 1,000 euros per year in a typical detached house.
• Effective ventilation removes moisture, carbon dioxide and pollutants, protecting both the health of the residents and the structures of the house.
• The system always requires a professional HVAC designer to ensure its correct dimensioning and operation.
• Investing in high-quality ventilation is an investment in living comfort, health, and maintaining the value of your home.
