Windows and solar gains
The definition of Passivehouse is driven by air quality and comfort.
“A Passivehaus is a building in which thermal comfort can be achieved solely by post-heating or post-cooling the fresh air flow required for a good indoor air quality, without a need for additional recirculation of air”. – Passivhaus Institut (PHI)
The houses we build using Passive house technique use as little as 10% of the energy used by typical buildings.
Passive houses are designed to remain at a comfortable temperature year-round, with minimal energy inputs required.
The structure of the building is incredibly air-tight and well-insulated and special windows are installed, allowing the house to be heated by the sun, internal heat sources, and heat recovery systems.
Even throughout the coldest months, conventional heating systems are rendered unnecessary.
And during warmer months “passive cooling” technique as shading and ventilation system is used
