The Herwig Blankertz and Max Born Vocational Training College in Recklinghausen now has new premises in converted colliery buildings. Two compact, generously glazed buildings, with an effective area of 17,600 m², form together with a five-court sports building a central public space, the Campus Vest. For comfortable conditions in the rooms, which permit concentration while working at any season of the year and any time of day, an integral energy and building concept was developed in which the CONCRETCOOL ventilation system has a central role along with the dual-shell building envelope and a replacement-air system. By exploiting the internal loads, the thermal storage capacity of the structure, and the weather-dependent sun-blinds, the energy needs for ventilation and heating have been minimised in comparison with conventional building management systems.
|Object:||Herwig-Blankertz- und Max-Born-Berufskolleg, Recklinghausen|
|Architects:||scholl architekten partnerschaft|
|Proprietor:||Kreis Recklinghausen - Der Landrat|
|Planning office:||Pfeil & Koch Ingenieurgesellschaft, Stuttgart|
|Scope:||17.600 m² conditioned area|
|System:||Concrete core cooling with air CONCRETCOOL|
|The ventilation system is integrated into the ceilings so that it is invisible.|
|Air flow rate:||9 m³/hm² (exch. rate = 2.7 x /h)|
In contrast to conventional systems, in which supply air is fed directly into the working areas, the air first flows through aluminium cooling tubes cast into the ceilings. Thereby the supply air cools the ceiling. At the same time the gain of heat is used to warm up the supply air.
Kiefer GmbH is a leading company in the field of ventilation, air handling and air conditioning technology. Our range of services includes consulting, planning and execution of systems for thermal comfort and industrial air conditioning, as well as the associated installation and maintenance. For more than three decades, Kiefer has also been selling high grade ventilation components worldwide, such as linear diffusers, wall passages, displacement outlets, chilled ceiling panels and concrete core cooling systems, developed in the company's own laboratories.
