People make CLAAS: With its new administration building at the company headquarters in Harsewinkel, the global manufacturer of energy-efficient farming machinery and devel-oper of agricultural technology is certainly living up to this motto. The high-efficiency buil-ding provides a modern, comfortable working environment which encourages communication between employees.
The four-storey building comprises an elegant entrance area opposite the Technoparc, conference and meeting rooms from the ground floor to the top floor, plus a new computer centre and the historical archive in the basement.
A covered atrium provides space for events, exhibitions and presentations. As the office areas have flexible divisions, they can be arranged as individual offices or open-plan spaces. The building features daylight-dependent lighting which is controlled via movement sensors for optimum results. The thermal load generated by people, computers, lighting, etc. in the offices during working hours is used to heat the atrium. Both measures contribute towards minimising energy and heat loss.
The new Atrium building features one CONCRETCOOL pipe module per 1500 mm construction grid. Each pipe module has a nominal width of 80 mm, approximately 5.5 running metres of active ribbed pipe and an air-side load of 50 – 75 m³/h. The specified quantity of fresh air (7.8 m³/h m²) which is pumped into the offices by the CONCRETCOOL system enters the pipes at an intake temperature of 12°C and is heated nearly to ambient temperature by the energy stored in the ceilings. When the ventilation technology system is operated for 12 hours, the CONCRETCOOL system can recool a stationary cooling load of 35 W/m² in the offices; with 20 hours of operation, it can even achieve 60 W/m². The operational ambient temperature does not exceed 24.5°C in normal operation. The extract air is extracted centrally in the corridors via the INDUSILENT cross-flow elements which are integrated in the corridor walls and feature sound absorbers.

In contrast to conventional systems, the supply air is not fed directly to the room, but first flows through aluminium cooling tubes embedded in the ceiling. The supply air cools the ceiling in the process. At the same time, the heat recovered is used to heat the supply air.
