Does a passive house need heating?
A passive house is built so that it is very energy efficient and comfortable at the same time without using a traditional heating system or active cooling. By using existing temperature, the required heating energy of a passive house is 90% lower than the energy needed for a conventional home.
How does a passive house work?
The strategy of a Passive House is to reuse "free" heat to heat the home. "Free" heat is generated from all electrical and gas appliances such ovens, refrigerators, computers and light bulbs. It goes through the heat recovery ventilator, and transfers the heat, to the incoming fresh air, before it leaves the building.
Can you open windows in a passive house?
Yes, you can. The idea that you can't open the windows in a Passive House comes from a misconception regarding the clever way that Passive Houses regulate the heating and cooling of a home. Passive Houses are “airtight”, which means they have no uncontrolled draughts in the windows, through the walls or under the floorboards.
What makes a house passive?
A Passive House combines high level comfort with very low energy consumption. A Passive House makes efficient use of the sun, internal heat sources and heat recovery ventilation to such a standard that conventional heating systems are virtually rendered unnecessary.
