Passive building is a set of design principles for attaining a rigorous level of energy efficiency while also creating comfortable indoor living spaces. The approach can be successfully applied to any type of building, including schools, churches, office buildings and skyscrapers.
The requirements for building passive house design certification vary depending on the specific certification program being used, but generally speaking, passive house design certification requires that a building meet certain standards for energy efficiency, comfort, and indoor air quality. Some of the key requirements for passive house design certification include:
1. Insulation: The building must have high levels of insulation to reduce heat loss and keep the interior at a comfortable temperature.
2. Airtightness: The building must be airtight to minimize heat loss and prevent drafts.
3. Energy-Efficient Windows: The building must have windows that are highly energy-efficient, to minimize heat loss and reduce the need for artificial lighting.
4. Mechanical Ventilation: The building must have a mechanical ventilation system to provide fresh air and remove indoor pollutants.
5. Energy-Efficient Heating and Cooling: The building must have an energy-efficient heating and cooling system, such as a heat pump or a ground-source heat exchanger.
6. Renewable Energy: The building must have a renewable energy system, such as solar panels or a wind turbine, to generate electricity and reduce the need for grid-sourced power.
7. Comfort: The building must be designed to provide a high level of comfort.
