The "BAKA" Awards 2015 were presented at the "Bau" Building Exhibition in Munich by Dr. Barbara Hendricks, Federal Minister for the Environment, Nature Conservation and Nuclear Safety. Dr. Hendricks said in her speech that the construction industry plays a "key role for climate and energy policy”.
1st prize for product innovation went to Colt for its “ClimaTower", an innovative low-energy system, providing heating, cooling and domestic hot water. The de-centralised and legionella-free hot water system provides climate control to individual rooms which allows the potential for energy balance between cooling and heating as heat is moved around the building.
Hotels in Germany consume around 145 kWh/m2 each year for heating and about 80 kWh/m2 for electricity. ClimaTower has been in operation for 18 months at the the Derag LivingHotel in Munich, where it has worked reliably and dramatically reduced energy consumption. Its performance is being monitored by the University of Rosenheim to validate its high energy efficiency performance. Average energy consumption of about 55 kWh / m² per year for heating, cooling and hot water are being achieved against a target low-energy hotels of 137 kWh/m².
These results demonstrate that ClimaTower can provide significant energy savings. It can also be applied to buildings such as student residences, apartment buildings, hospitals and apartment complexes.
For all of these reasons, the jury awarded ClimaTower with the 1st prize for product innovation.
