Over the last few decades, our climate has changed drastically and it is becoming increasingly obvious that we need to change the way we live, work and build in order to protect our planet. A low-energy house is one way to reduce our energy consumption and therefore our CO2 emissions. A low-energy house is a building that has been built to use as little energy as possible. It is able to cover a large part of its energy needs through renewable energy sources, such as solar energy or geothermal energy. A low-energy house is therefore not only environmentally friendly, but also economical, as it leads to long-term savings in energy costs. The idea of a low-energy house dates back to the 1970s, when the oil crisis led to an increased awareness of energy consumption. Since then, however, technology has evolved and new materials and technologies have been developed that can further reduce a home's energy consumption.
