Is building a Passive House worth it?
Passive house construction can greatly reduce heating and cooling costs in buildings, and the concept is not limited to the residential sector. The main benefits of a passive house project are durability, high air quality, occupant comfort, and potential energy savings of over 90%.

Can you have a fireplace in a passive house?

How do I convert my house to passive?
Replacing or installing new insulation in the attic or roof. Installing new ventilation systems with heat recovery or passive roof and wall ventilation. Installing draught proofing measures around existing windows and doors. Increasing the overall air tightness of the house.

Can a passive house have a basement?
Instead, walkout basements can be included in a thermal enclosure. Though the above grade portion requires insulation for PH (Passive House), it can also have windows for natural light, and even solar gains, so the basement can be quality living space. This is a TFA (Treated Floor Area) return on the investment.
How much extra does a passive house cost?

There are three essential design features in a passive home: 1. Air-tightness It’s vitally important that heat loss is minimized through unwanted and unnecessary leakage of air.
What type of insulation do I need for a passive standard home?
As a general rule of thumb, homes retrofitted to passive standard require R48 wall, roof and below slab (or floor) insulation. 3. Proper windows For thermal comfort, it’s very important that a passive approved window is used. These are triple glazed units with insulated frames equivalent to an R12.
