4. Cooling and Ventilation – Jerome Rodary

5. Building general ventilation: adding of 2 new ventilation units total flowrate: 210 000 m3/h total heating power: 2 440 kW Existing ventilation unit inside EHN1 building Fire fighting water hose Argon extraction unit Fluid networks

6. Electric infrastructure - James Devine This work unit for electric infrastructure includes consolidation up-stream of EHN1, which must be done to connect the extension. The cost sharing (proposal) is based On the surface of the extention vs. existing hall. EL will need a consolidation budget (from NA Cons) of 1’488 kCHF in addition to this sum.

7. MEF-Items A full FTE from MEF for the project coordination during the whole project.
