Green Hall building’s double facade, whose total area exceeds 5600 sq. m., is like an energy-saving shield that prevents the building from overheating during summer, and traps warmth inside during winter, as well as provides reliable protection against city noise. During winter, this system will enable to preserve heat and use less energy. Aluminium-glass constructions, which were manufactured in Germany, were used in the facade of Green Hall 2.
The facade is designed so that it would let in as much solar heat as possible and preserve it inside. It has an impressive 0,6 W/m2k heat transfer coefficient which complies with the highest thermal resistance requirements established for passive houses. When manufacturing window systems, environmentally-friendly castor oil-based insulators are used as an alternative for petroleum-based polymers.
The sound insulation coefficient (Rw) of the building’s walls reaches 40 Db and reduces noise coming from the city, so that it would not distract attention from a world-changing project.
