There are usually two important questions that are asked — Why would you build a Passive House and What is a Passive House.
The posts focus on the amenities first including the fact that a Passive House:
- needs very little heat
- has filtered fresh air 24/7 regardless of whether your windows and doors are open or closed
- is sealed from bugs / critters, dust and allergens
- has significantly less outside street noise
- has reduced heating and cooling bills by up to 80% -90%
- Is the path to Net Zero (creating at least as much electricity your home needs via renewable energy i.e. solar, wind, etc.)
Wikipedia defines Passive House well –
“Passive house is a rigorous, voluntary standard for energy efficiency in a building which reduces the buildings ecological footprint. It results in ultra-low-energy buildings that require a little energy for space heating or cooling.
The standard is not confined to residential properties; several office buildings, schools, kindergartens, and supermarkets have been constructed to the standard. Passive house design is not an attachment or a supplement to architectural design, but a design process that integrates with architectural design.”
