About this tender
This procurement concerns heating, ventilation and air-conditioning (HVAC) installation work at a commercial and industrial site operated by Access e.V. The source text is a building description that frames the HVAC scope, not the full tender specification. The site comprises a four-storey office and laboratory block of concrete construction (about 1,000 m² footprint, Parts A and B), attached to a two-part steel hall with sandwich-panel cladding. Part C is a high hall of about 2,000 m² with a clear height of roughly 10.5 m, housing production equipment. Part D is a lower hall of about 2,500 m² with a clear height of roughly 5.7 m, housing workshop, quality-control and manufacturing functions. Heating and cooling for the building are supplied entirely by electric generators installed on the roof of Part D. The heating and cooling plant room is in the northern section of the high hall and distributes energy to both process systems and building services. Ventilation units sit on the roofs of the areas they serve (Parts A, B and D). Part C is largely unventilated. Potable water is assumed to be already routed to the handover point in the sanitary plant room. Electrical supply comes from the medium-voltage network via a switchgear on the southern part of the plot, with transformers on the western hall side and the main low-voltage distribution board in the high hall. Photovoltaic equipment is on the roof surfaces. The notice title identifies the work as HVAC installation. The page does not state the duration, the detailed deliverables or the lot structure.
Key requirements
- ✓Design and installation of HVAC systems across four building sections (office/lab, two production halls, workshop/QS areas)
- ✓Integration with electric heat and cooling generators located on roof of Building D; distribution from central plant in northern high hall
- ✓Ductwork and ventilation units on roofs of Buildings A, B, and D; Building C largely unventilated
- ✓Coordination with existing electrical infrastructure (NSHV in high hall), water supply, and photovoltaic systems

About this sector
Heating and cooling funding supports heat pumps, district heating, thermal networks, efficient cooling and the removal of fossil boilers. It arrives through national support schemes, local authority programmes and procurement for heat networks. Applicants typically need heat demand assessments, a connection plan and an operator for the system.
