Passive house construction involving glass wool thermal insulation. The Passivhaus Institute has a separate certification recognising appropriate retrofitting work which has a lower level of acceptance than for a full passive house building, called the EnerPHit Standard effectively it has the same criteria as passive house standard with a higher space heating demand of 25kWh/m2/year, rather than the passive house level of less than 15kWh/m2/year. The principles can also be applied to older houses, although it may be harder to reach the same levels of insulation as a newbuild. While the majority of passive houses are built in German-speaking countries and Scandinavia, they can be seen in a range of buildings across Europe, Japan and the USA.Īnyone building an energy efficient house can apply to have it certified by The Passivhaus Institute certified passive houses must comply with the planning system which enables the design to be altered until the house reaches the required building standard of energy efficiency. Their work followed research into why low energy buildings often failed to deliver anticipated energy savings and lower carbon emissions, and the initiative was developed by The Passivhaus Institute in Germany. The origins of passive house buildings go back to the 1980s, when physicist Professor Wolfgang Feist and construction engineer Professor Bo Adamson set out to design buildings with more insulation which were energy efficient. Passive houses are orientated to face the sun. Passive house standards create sustainable buildings, with a low energy demand, aimed at reducing energy consumption. All of the passive house components must be linked in the design of a new home which must be viewed in its entirety no single element can be left out. The design process involves strategic orientation of the dwelling to maximise passive solar gain and enable precise window placement. The Energy Saving Trust describes passive houses as the gold standard in energy efficiency, creating buildings to rigorous design standards so that they maintain an almost constant temperature for space heating they retain heat from the sun and need little additional heating or cooling. ![]() By making maximum use of the sun and high levels of insulation and airtightness, an energy efficient building is created and a living space with high levels of thermal comfort. So, if you are keen to live in an energy efficient home, dive in to find out all the facts! What is the passive house concept?Įnergy efficient construction is at the heart of the passive house design technique. ![]()
