RENOVATION WORKS AND NEW WORKS ENERGY EFFICIENT
Passive House projects are based on several key principles:
1. Insulation and airtightness: Passive buildings are highly insulated to minimise heat loss in winter and heat gain in summer. In addition, special attention is paid to the airtightness of the building to prevent unwanted air leaks.
2. Controlled ventilation: A mechanical ventilation system with heat recovery is installed to ensure a constant supply of fresh, filtered air without excessive heat loss.
3. Orientation and design: Solar orientation is exploited and the building layout is planned to allow maximum use of sunlight and protection from excessive heat.
4. High-efficiency windows: High-quality windows and doors with a low heat transfer coefficient are used, reducing thermal losses through these elements.
5. Elimination of thermal bridges: Points where heat can easily escape through structural connections, such as corners or joints, are avoided.
6. System load: The need for conventional heating or cooling systems is minimized, relying on design efficiency and heat recovery.
7. Analysis and modeling: Simulation tools and precise calculations are used to plan and optimize building efficiency prior to construction.

Passive House buildings aim to achieve a high degree of thermal comfort and indoor air quality, maintaining constant and pleasant temperatures throughout the year without relying on conventional heating or cooling systems. This certification is an internationally recognised standard that promotes sustainable and energy-efficient construction, helping to reduce energy demand and greenhouse gas emissions associated with buildings.
