Passive Homes

Updated: Jun 6





Passive homes, also known as passive houses, are energy-efficient residential buildings designed to minimize energy consumption for heating and cooling.  The concept originated in Germany in the late 20th century and has gained popularity globally for its focus on sustainability and environmental responsibility.

Key Features of Passive Homes Include

High Insulation: Passive homes have an exceptionally well-insulated building envelope, including walls, roof, and floor. This ensures minimal heat transfer between the interior and exterior, reducing the need for active heating or cooling.

Airtight Construction: Passive homes are constructed to be airtight, preventing drafts and heat loss. This is achieved through careful sealing of windows, doors, and other potential air leakage points.

Ventilation with Heat Recovery: A mechanical ventilation system with heat recovery is a crucial component of passive homes. It ensures a continuous supply of fresh air while recovering heat from the exhaust air, maintaining a comfortable indoor temperature.


Solar Gain: Passive homes leverage passive solar design principles to maximize natural sunlight for heating. South-facing windows and proper shading are incorporated to optimize solar gain during colder months.

Energy-Efficient Windows and Doors: High-performance windows and doors with advanced glazing technologies are used to minimize heat loss and control solar gain.

Thermal Mass: Some passive homes incorporate thermal mass, such as dense materials like concrete, to store and release heat gradually, helping to regulate indoor temperatures.


Efficient Appliances and Lighting: Energy-efficient appliances and lighting fixtures are used to further reduce electricity consumption.
