From integrated planning over resources-saving construction to efficient operation for non-residential buildings, exhibitors and visitors to "BuildingEnergyTechnologies BET" concentrate in Hall 27 already for the 2nd time. Manufacturers will show systems and components of higher power as well as service providers technically sophisticated, often individual solutions for energy-efficient buildings. Instead of thinking in crafts, integrated planning is in demand among the SME exhibitors. This results in a variety of often equivalent technical approaches, the parts of which are covered here by manufacturers and contractors of building services.The Speakers’s Forum "BuildingEnergyTechnologies" contributes up-to-date information in lectures and panel discussions, in direct neighbourhood to the special exhibition "Decentralized Energy Supply". 7 sponsors of the special exhibition BET also provide significant content and its Europe-wide dissemination.
