By choosing Herrala Houses’ carefully designed and thought out prefabricated houses, the builder gets an ecological and energy-efficient home.
“Low-energy and passive house construction is a current trend. Herrala Houses has been building low-energy houses for some time now, and passive houses were introduced in our range a couple of years ago,” Sales Manager Kimmo Kurki explains.
According to Kurki, consumers nowadays are well informed in terms of energy and eco-efficiency issues. This is evident already in the planning stage.
“The discussions we have with our customers usually concern issues such as the heating system they’ve chosen. As houses have been getting larger, many customers have settled on environmentally friendly geothermal heating and some have installed solar panels to provide additional heating. As far as Herrala Houses is concerned, any type of heating system is possible,” Kurki says.
Kimmo Kurki says that the demand for Herrala Houses’ passive homes has been steady. The wall structure of a passive house that consumes very little energy has approximately double the amount of insulation compared with a standard single-family house. Kurki thinks it important that well-informed customers can opt for an extremely low-energy passive house as their home.
“Energy consumption and the need for heating and cooling must be determined case-by-case, so the planning must take energy-efficiency issues into account as a whole, right from the very early stages. It is very important that the houses are airtight, because in the end, a house can only be called passive after airtightness measures and energy consumption monitoring have confirmed that it is passive.”
As of last summer, Herrala House customers have had a choice between traditional glass or rock wool insulation and ecological Ekovilla, a wood-based fibre insulation. As the insulation can be blown in, the installation in roofs, basement floors and walls is quick. The end result is a warm, airtight, breathing, and safe home – in an instant. Ekovilla thermal insulation conserves nature, as it is made from wood fibre, i.e. recycled paper. It binds the carbon in the fibre for all of its lifetime, thus lowering the energy consumption of the household. Seamless and airtight, Ekovilla insulation cuts heating costs efficiently, thereby also reducing the house’s carbon footprint.
