Latest Tech Means Reduced Costs and a Greener Home

Passive House helps you create a reduced carbon footprint, providing a win/win for the planet and your wallet.  

Everyone knows how important it is to minimise energy use. It helps preserve dwindling natural resources, and if everyone does their bit, can make a genuine difference to the planet for future generations. There is also a more immediate and tangible benefit, in that with fuel costs going up every year, it makes financial sense to use as little as possible.

As if that wasn’t enough of a win/win, there is also a third consideration. If you are contemplating any kind of building work or an extension, and it needs planning permission, the local authority will pay close attention to its green credentials, including the projected energy consumption.

Get the figures as low as possible, and that is one box ticked for the planning officers. And that’s where Internorm windows and doors can really come into their own.

About Internorm

Internorm started making high quality windows and doors in 1931. The brand was established in Linz, Austria, by Eduard Klinger, and today, this family run business is still run by members of the Klinger family, grandchildren of the founder.

Despite its long history and traditional values, Internorm is one of the most cutting edge manufacturers, using the latest techniques and materials. These are designed to create a modern living environment that embraces the Passive House (or PassivHaus) industry standard.

What is Passive House?

Passive House is a global standard for energy efficient construction. A typical Passive House construction uses just 10 percent of the energy used by a normal house for heating and cooling.

By using the most energy efficient materials, insulation and construction techniques, it has so little heat loss that it can typically be kept warm using just sunlight and the heat produced by occupants and appliances. This practically eliminates the need for additional heating and air conditioning systems.

The Passive House Standard also sets out to protect the building’s structure, using sophisticated systems of ventilation and heat transfer to keep the air fresh and minimise condensation, without any loss of heat energy.

How to meet the standard

The standard is comprised of strict energy efficiency requirements for new building construction. There is also a related standard for the renovation of existing buildings, which has slightly more lenient performance criteria. There are five key stipulations that must be met to achieve certification:

1) Space Heating Demand: A maximum 15 kilowatt hours per square metre of living space is permitted per year (or 10 Watts per square metre peak demand).

2)  Space Cooling Demand: Approximately matches the heating demand requirements, but allows a little extra for dehumidification.

3) Primary Energy Demand:  The total energy used in the entire building operations (meaning heating, cooling, hot water, lighting, electrical equipment and so on) is limited to 120 kilowatt hours per square metre of living space per year.

4) Airtightness: Maximum 0.6 air changes per hour at a pressure of 50 Pascals.

5) Thermal comfort: A maximum 10 percent of the hours in any given year are permitted to exceed 25C for all living areas.
