High Energy Efficient Homes: The Zero Energy Building (ZEB)
Zero-consumption houses are no longer an unattainable dream, but an established building practice, as enshrined in the European Community’s 20-20-20 directive. This ambitious goal promotes energy efficiency and sustainability for all member states. To learn more, you can visit the official website: 20-20-20 Directive.
An Evolution in Construction Techniques.
Until recently, constructing truly well-insulated buildings seemed impossible. In the 1990s, just a few centimeters of thermal insulation was enough to meet current regulations; later, the thickness of insulation increased: from 10 cm to 15 cm, to 20-25 cm today, thus achieving true super-insulation.
The Recipe for Energy Efficiency.
The solution is simple: use a significant amount of insulation and choose materials that provide exceptional thermal efficiency, both in summer and winter. This approach makes it possible to heat the house efficiently, to the point that the energy produced by appliances and the calorie emitted by the inhabitants’ human bodies are sufficient to achieve comfortable temperatures.
Sustainability and Renewable Energy Sources.
By adopting these construction techniques, we avoid the use of nonrenewable energy sources such as gas or diesel fuel, instead favoring the sun as the primary source of energy. With photovoltaic and solar thermal systems, we can self-produce both electricity and heat, ensuring thermal efficiency and zero energy consumption.
Ecological Materials for a Sustainable Future
To provide thermal insulation and achieve the goal of the zero-consumption house, we use materials not derived from petroleum, but from mineral sources such as rock wool or plant sources such as wood fiber. This choice not only improves summer insulation, but also makes our buildings more environmentally friendly.
Conclusion
Investing in energy-efficient homes means setting our sights on a sustainable and responsible future. By adopting modern technologies and environmentally friendly materials, we can contribute to a healthier environment for ourselves and future generations.
