Nearly Zero-Energy Buildings: most cost-efficient
Astron’s research and development led to remarkable optimization solutions, which enabled the economic applicability of the German KfW 55 standard as well as Nearly Zero-Energy Buildings (NZEB). Our building system relies on detailed planning of airtightness combined with improved details and new calculation approaches for global optimization.
In addition, we offer optimization of thermal bridges, thus reducing the fixed price approaches of the EnEv. It is also crucial to consider the interdependencies between systems engineering and building envelope. Further important factors are ventilation and lighting (artificial and daylight).
We are confident that we can offer a far more economic solution for most building projects, especially because Astron solutions allow us to use KfW financing as well as the additional allowance of 5 % of the investment sum. As an example, we compared the standard solution of a production building to an optimized solution using actual and real values. The result is groundbreaking: A KfW55 solution from Astron ist 10 % more cost-efficient!
