Introduction: sustainable construction: for what, what and how?
We are consuming too much energy. This consumption has important consequences on our climate, our environment and our wallets. This is the reason why we have to live, build or transform while making sure to save energy. The production and combustion of fossil fuels (oil, coal and gas) generate carbon dioxide (CO2) in the atmosphere.
These emissions are the cause of global warming, climate change and the rise in ocean water levels. In addition, fossil fuels are slowly but surely running out. Today, oil reserves have already been used at 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 up and move around, but we will have to do it in a more qualitative way. The home of the future should therefore not only be able to be economically constructed (otherwise it will never be built), but it must also be thermally and acoustically insulated, be robust, durable, fire-resistant, ecological and healthy.
Today, low energy or neutral energy buildings represent a challenge that designers, entrepreneurs and producers are called upon to meet.
Orientation to the sun, recovery of heat from ventilation air, use of sustainable sources of energy, combined with an airtight concept, high insulation values , constructions free of thermal bridges and building elements with heat accumulation are essential requirements which require a multidisciplinary approach.
Silka, Ytong and Multipor are doing everything to meet this challenge. You will notice that in this brochure, thanks to Silka, Ytong and Multipor, you will not only be guaranteed to benefit from an energy-efficient living environment, but also environmentally friendly, healthy and sustainable.
