Passive House is a building standard that focuses on energy efficiency, comfort, and sustainability. Here are some aspects of the Passive House principle in buildings:
Energy Efficiency: Passive House buildings are designed to use very little energy for heating, cooling, and ventilation. The building envelope (walls, roof, windows) is highly insulated, and the windows are triple-paned with low-emissivity coatings. This reduces the need for space heating and cooling, as well as energy used for lighting, appliances, and hot water.
Air-Tightness: Passive House buildings are designed to be air-tight to prevent energy loss due to air leakage. This is achieved by using high-quality building materials, such as airtight membranes, tapes, and gaskets, to seal all the openings in the building envelope. A mechanical ventilation system with heat recovery is installed to provide fresh air and maintain indoor air quality.
Thermal Bridging: Passive House buildings are designed to minimize thermal bridging, which is the transfer of heat through the building envelope where the insulation is interrupted by structural elements. This is achieved by using advanced framing techniques, such as insulated headers and continuous insulation, and by carefully selecting building materials to minimize thermal bridging.
Renewable Energy: While Passive House buildings are designed to use very little energy, they still require some energy for lighting, appliances, and hot water. Renewable energy sources such as solar panels, wind turbines, and geothermal systems can be used to generate this energy.

Comfort: Passive House buildings are designed to provide a high level of comfort for occupants. The indoor temperature is kept within a narrow range, and the ventilation system provides fresh air without drafts. The windows
