The new Grohe Zinc Die Casting Factory Project is a detached extension building on the Grohe Siam industrial real estate in Klaeng, Rayong, Thailand. To show Grohe’s commitment to sustainability, the management decided to strive for a silver certification according to the German Sustainable Building Council DGNB.Therefore, Grohe has contracted EGS-plan to develop a sustainability concept for the 14.800 m2 building. Main goal of the concept is to achieve a good balance between the ecologic, economic and socio-cultural quality of the building. To achieve a sufficient thermal comfort in the non-air-conditioned production area the climate concept comprises thermal insulation in the roof to reduce long wave radiation, enhanced natural ventilation and a balanced window-to-wall ratio.Further sustainability features are a ecological water concept, green resting areas in and outside the building and a 1200 kWp photovoltaic system. The sustainability concept of the new Grohe Zinc Die Casting Factory is unique in Thailand and is the first DGNB Deutsche Gesellschaft für Nachhaltiges Bauen e.V. certified factory building in South-East Asia.
