Introduction: sustainable construction: for what, what and how?
We are consuming too much energy. This consumption has significant consequences for our climate, our environment and our wallet. This is the reason why we must live, build or transform while making sure to save energy. The production and combustion of fossil fuels (oil, coal and gas) lead to the release of carbon dioxide (CO2) into the atmosphere.
These emissions are at the origin of the warming of our earth, of climate change and of the increase in the water level of the oceans. In addition, fossil fuels are running out slowly but surely. Today, oil reserves have already been used up to more than 50%.
However, consuming less raw materials and energy does not mean that we have to reduce our comfort to return to the standard of living of our ancestors 100 years ago. Quite the contrary. We will continue to heat and move around, but we will have to do it in a more qualitative way. The home of the future must therefore not only be able to be built economically (otherwise it will never be built), but it must also be thermally and acoustically insulated, robust, durable, fireproof, ecological and healthy.
Today, low-energy or neutral-energy buildings represent a challenge that designers, contractors and producers are called upon to take up.
Orientation to the sun, heat recovery from ventilation air, use of sustainable sources of energy, combined with an airtight concept, high insulation values , constructions free from thermal bridges and heat-accumulating construction elements are essential requirements which require a multidisciplinary approach.
Silka, Ytong and Multipor are doing their utmost to meet this challenge. You will notice that in this brochure, thanks to Silka, Ytong and Multipor, you will not only be assured of enjoying an energy efficient living environment, but also environmentally friendly, healthy and sustainable.
