To create a Nearly Zero Energy Building (NZEB) home, i.e., a highly energy-efficient building that requires little energy for heating and cooling, it's necessary to follow some fundamental principles. Here are the steps:

Thermal insulation: The home must have high-level insulation throughout its building envelope to minimize heat loss. You can opt for a thermal insulation system, i.e., insulation on the exterior walls, or a double-wall system with an insulating cavity.
High-efficiency windows: Windows must be low-emissivity, equipped with double glazing and a highly insulating frame. They must also ensure good airtightness.
Controlled mechanical ventilation systems: A highly energy-efficient home must have a controlled mechanical ventilation system capable of ensuring controlled air exchange and good indoor air quality.
Use of renewable energy sources: The electricity for the systems must be generated from renewable sources, such as photovoltaic, solar thermal, and wind power.
High-efficiency heating and cooling system: The home must be equipped with a low-energy heating and cooling system, such as a high-efficiency heat pump system, which uses energy from the outside air to heat and cool the home.
Use of eco-friendly materials: When building an NZEB home, it is important to use eco-friendly, long-lasting materials with low environmental impact.
Energy management: The home must be equipped with an energy management system capable of monitoring energy consumption and efficiently regulating the heating and cooling systems.
In short, building an NZEB home requires careful design and a careful selection of materials and systems. The result is a highly energy-efficient building, with significant environmental and economic benefits.
