The double-skin construction of the building's facade protects employees working in the building from city noise and preservesthe heat that circulates inside. This saves energy and creates an ideal environment for work. 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.
