How does Passive House design differ from conventional construction designs?
Passive House design differs from conventional construction in many ways. Firstly It uses airtight construction, high-performance insulation, triple-pane windows, and mechanical ventilation to maintain a comfortable indoor temperature without relying on the external heating or cooling system. Secondly, it also relies on a careful balance of passive solar gain and shading to minimize the need for artificial lighting. You won’t ever find these features in a traditional house.
How much does it cost to build a Passive House?
The cost of building a Passive House depends on factors comprising the size of the building, the complexity of the design, and the cost of labour and materials. Well, the upfront cost of a Passive House is higher than a conventional building due to the utilization of high-end materials but the long-term savings in energy costs will lower your living cost in the future.
How does ventilation work in a Passive House?
The ventilation mechanism of the passive house used a mechanical ventilation system with heat recovery. This system exchanges stale indoor air with fresh outdoor air while recovering heat from the outgoing air to preheat the incoming air. Thus you get a well-maintained constant indoor temperature while improving indoor air quality.
How does a Passive House design affect indoor air quality?
Its ventilation mechanism improves indoor air quality by providing a continuous supply of fresh air The ventilation system effectively filters incoming air to remove pollutants and allergens while exhausting stale indoor air to remove moisture and indoor pollutants.
What is the lifespan of a Passive House?
The lifespan of a Passive House is similar to that of a conventional building. The airtight construction and high-performance materials used in Passive House design helps to protect the building from moisture damage, mould, and other issues that can shorten the lifespan of a conventional building.
