Passive House principles:
• Super insulated building envelope
• Thermal bridge free construction
• Airtight & Windtight exterior envelope
• Ventilation through energy recovery ventilator
• Highly efficient windows & doors.
• Solar & heat gain optimization
The Passive House concept represents today’s highest energy standard for building construction. Heating and cooling energy consumption of buildings can be reduced by up to 90%. A Passive House is a very well-insulated, virtually airtight building that is primarily heated by passive solar gain and by internal gains from people and equipment. Energy losses are minimized. Any remaining heat demand is provided by a very small source. Shading and window orientation minimizes heat gain, helping to limit and minimize any cooling load. An energy recovery ventilator provides a constant, balanced fresh air supply, creating comfortable indoor air quality.
“A Passive House is a comprehensive system. “Passive” describes this system’s underlying receptivity and retention capacity. Working with natural resources, free solar energy is captured and applied efficiently, instead of relying predominantly on ‘active’ systems to bring a building to ‘zero’ energy. High performance triple-glazed windows, super-insulation, an airtight building shell, limitation of thermal bridging and balanced energy recovery ventilation make possible extraordinary reductions in energy use and carbon emission.” - Passive House Institute US
