The construction of a low-energy house offers much room for design to architects and constructors. Additionally, low-energy houses can be built in a massive or light fashion. Regardless of the construction material or heating and ventilation system the constructor decides to use, all low-energy house concepts aim at reducing the heat loss of the building shell or heat loss due to ventilation. Energy-saving construction doesn't have to be expensive.
Not only the high living comfort and the low running costs are arguments in favour of low-energy houses. Thanks to the high-quality construction process, low maintenance and upgrading costs can be expected for the future.
