Design and Calculation Criteria

Heating

Heat Load calculation according to EN 12831 “Method of the calculation of the

design heat load”. Due to the extraordinary room height special factors must

be taken into account from Annex B.1

Cooling

Cooling load calculation according to VDI 2078 “Calculation of thermal loads

and room temperatures (design cooling load and annual simulation)”.

• Specific feature for embedded surface cooling: Due to the to the

massive concrete slab and the low heat transfer for cooling will be

possible

• Design conditions: Inlet temperature 16°C, outlet temperature 20°C and

room temperature 26°C

• Cooling capacity: between 20 and 30 W/m²
