The national determination method NTA 8800: the new bible for the energy performance calculations, is applied in the energy assessments and is necessary to course this part of the energy transition. First, we examine the situation for counteracting and limiting energy consumption through compact building shapes and insulation of the building’s exterior envelope, such as facades, roofs, and floors.
The second step is to use (fossil) energy sources as efficiently as possible to meet the remaining energy needs. This includes the use of heat pumps or low-temperature heating. Finally, the maximum use of sustainable energy sources, such as wind, water and solar energy.Within these types of projects, Iv-Bouw takes it much further than just checking whether a building can meet energy label C and the necessary adjustments to achieve this. In 2030, these same buildings will no longer be required to satisfy energy label C but energy label A. In short: the work is far from over after the 1st of January next year.
“This is perhaps the most interesting thing about these types of projects,” says Michiel. “Especially because every building is unique. Where possible, we provide advice to improve the label, which is something from which everyone will benefit.” As far as Michiel is concerned, it is not just a ‘must’ for organisations and companies to comply with an energy label because it is suddenly necessary due to the Climate Agreement and government policy from The Hague. But instead, there is an urgent message lurking in the shadows. The raw materials are running out and it is nothing short of an absolute must to have energy-efficient buildings.
“Since the industrial revolution, we have long believed that everything can be extracted from the earth,” he continues. “Minerals that the earth has taken billions of years to form. However, we no longer look to the ground for solutions, but instead, upwards; to our most important source of energy: the sun.” Natural energy sources will become even more critical in the coming years, Michiel is convinced. Hydrogen will play a crucial role, especially because wind and solar energy carry limitations. The wind does not always blow hard enough, nor does the sun shine 365 days a year. And currently, it is hardly possible to store such energy, except in a car and on a bicycle. The result is that we are always left with surpluses and shortages.
