Passive houses are built to optimise thermal gain and minimise thermal losses. This means that the energy required to heat a passive house is 90% lower than that of other buildings. Passive homes therefore do not rely on traditional heating sources like furnaces or boilers.

What are the benefits of passive houses? Passive houses consume about 90% less heating energy than older buildings and 75% less energy than the average newly-constructed building, the Institute says. They only need an additional source of heating when the weather is very cold, while in hot summer months air conditioning is unnecessary as insulation keeps the heat out.

What is Passivhaus? Passivhaus is an internationally recognised energy-performance standard that originated in Germany in the 1990s. It certifies low-energy buildings with high levels of insulation and airtightness. Buildings of this kind often make use of triple glazing, solar heat gain and energy recovery ventilation systems.

How much energy does a passive house use? As this graphic shows, a Passive House needs just 15 kWh of heating energy per square metre net floor surface per year (15 kWh/m2a). For an average-sized UK home, that’s the equivalent of around £50 of gas per year.

How many Passivhaus buildings are there? It was developed in 1990, over 25 years ago and some estimates suggest there are well over 50,000 Passivhaus buildings around the world. The Passivhaus has rigorous design standards and can be certified to prove the building has been designed to the assured Passivhaus criteria.

What are the benefits of passive houses?

What are the benefits of passive house standards? Good ventilation strategies and solar shading mean that your house is less likely to overheat on warm & sunny days; this is considered in the Passive House calculations. 9. Eco-friendly. As your house will require less energy to heat, building to Passive House Standards is a sustainable and environmentally-friendly build method.

How do passive house owners power their homes? By using energy-efficient appliances and alternative energy sources like solar panels or wind turbines, many passive house owners can power their homes with little or no reliance on the electric company or other polluting sources of energy.

Should you invest in a passive home? These requirements include limited energy needed to heat a home and run appliances, airtightness, and regulated temperatures all year round. As a landlord, deciding to invest in a passive home not only benefits the planet but your residents as well, and it can help you attract more desirable tenants.

Are passive houses eco-friendly? Basically, with the design of passive houses, fuel bills will be significantly lower because of the reduced energy consumption. This would then be extremely beneficial to the end-user since they can save money as well as help to alleviate fuel poverty. From the definition of a passive house, you can tell that it is definitely eco-friendly.
