Passive House is a construction standard that aims to create energy efficient homes. The aims are to make a thermally comfortable, eco-friendly, and affordable building all simultaneously. In turn, these elements work together to create a property that requires little or no energy for both your heating and cooling systems. With more people looking for a cost effective solution, Passive House ensures an insulated and ventilated system that retains heat without relying on central heating. So, how much electrical energy does a Passive House use?

How Much Electrical Energy Do Passive House Recommend?

Energy use is usually measured from the area and time, in the short term, kWh/m2yr. The larger the area, the smaller the energy use appears to be. Most standards that deal with energy use the total area of a building, whereas Passive House takes only the usable living area into account. Passive House is measured with a smaller area than others. Areas with lower ceilings are only partially taken into account whilst stairs, unheated areas etc, are not included – this is because it excludes any areas that cannot be used fully. This makes Passive House measurements more reliable than others.

Passivhaus homes specify no more energy being used than 120 kWh/m2yr. The main reason is that all energy, including heating, cooling, electricity, and other elements, is taken into account. Most standards usually leave electricity out, but Passive House considers this equally important. One of the main ways to compare energy requirements is to ensure that each refers to the same elements, so this can vary – so for more information, contact Internorm today.

In addition to this, Passivhaus buildings use their heat from internal sources. For example, waste heat from lightning, white goods and other electrical devices and even human body heat from the people inside the building (this is due to humans emitting an equivalent of 100 watts of radiated thermal energy)! With these elements, conventional heating is not required as often. Passive Houses sometimes have a dual purpose of 800-1,500 watt heating elements in their air supply (just in case of freezing temperatures). Still, their sustainable sources transform the need for central heating, saving you money on electric and heating bills!

Passivhaus Certification – What’s the Difference?

As the Passivhaus principal has been spreading all over the world, Germany has advanced the Passivhaus certification. Dr Feist, who founded the Passivhaus idea, is the owner of the private organisation “Passivhaus Institut” in Darmstadt, which developed this building standard 20 years ago and managed to spread it into many countries.

The independent test centre Rosenheim (like the BBA in the UK) has developed a new Passivhaus certification for windows and thereby has
achieved an official standard. Dr Feist is only interested in the thermal performance, whereas Rosenheim is also interested in the physical tests of the window and its performance, like water tightness, air permeability and shock resistance.

The thermal performance of Rosenheim’s certification is more detailed – it does not state the PSI or Uf value, but instead details the temperature factor of the glass edge and of the main building. It also measures the average
temperature factor of the frame profile as well as the Uw installed.
