What is the Passive House Calculator & How does it work?

A Passive House is a building standard that focuses on significantly reducing heating and cooling needs by improving insulation, air sealing, and passive solar design. This approach not only enhances comfort but also reduces energy consumption and carbon footprint.

The core principle of the Passive House is to achieve a Primary Energy Demand (in kWh/m² per year) that is less than 60 kWh/m² for heating, cooling, ventilation, and domestic hot water. This is achieved through meticulous design and construction techniques.

Primary Energy Demand = frac{Total Energy Consumption}{Building Floor Area}
Primary Energy Demand = Total Energy Consumption / Building Floor Area
