A passive house is a type of building that has been designed and constructed with energy efficiency in mind. The goal of a passive house is to minimize its ecological footprint by reducing its energy consumption as much as possible, while still providing a comfortable living environment for its occupants.
To achieve this level of energy efficiency, several design principles are followed during the construction process. These include using high-performance insulation and windows to reduce heat loss, employing efficient heating and cooling systems that minimize energy consumption, and utilizing natural light and ventilation to reduce the need for artificial sources.
Overall, a passive house is designed to use significantly less energy than a traditional building, resulting in lower utility bills and reduced environmental impact.
