ECOLOGY & ENVIRONMENT CALCULATOR
Passive House Calculator
Calculate the energy efficiency and environmental impact of your home using our Passive House Calculator.
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
Parameters

Frequently Asked Questions
What is the main goal of a Passive House?
The main goal of a Passive House is to significantly reduce heating and cooling needs, leading to lower energy consumption and a smaller carbon footprint.
How much primary energy demand should a Passive House have?
A Passive House should have a primary energy demand of less than 60 kWh/m² per year for heating, cooling, ventilation, and domestic hot water.
What are the key components of a Passive House design?
Key components include improving insulation, air sealing, and passive solar design to enhance comfort and reduce energy consumption.
Can any building be designed as a Passive House?
Yes, any building can be designed as a Passive House if it meets the specific criteria for energy efficiency and comfort.
What are the benefits of designing a house as a Passive House?
Benefits include improved indoor air quality, reduced energy costs, increased comfort, and a smaller environmental impact.
How do I calculate the primary energy demand for my building?
You can use a Passive House calculator to estimate your building’s primary energy demand based on its size, location, and design features.
Is there a cost associated with designing a Passive House?
While initial costs may be higher due to improved insulation and materials, long-term savings from reduced energy consumption can offset these expenses.
