 In 1987, the French government decided to build the new Ministry of finance on the site of Bercy.
The new building (260 000 m²) is occupied by 5000 persons. It includes restaurants, banks, a post office, a nursery, etc. It is highly equipped with high technologies (security systems, automatic document carrier, etc.)
The building is air-conditioned by 5 chillers of 1100 kW each and 1 STL-00-448 (25 000 kWh stored daily in eight tanks of 56 m³ each).

     

     The STL is used to shave the peak demand in summer.

Technical Data

Daily Cooling Energy Consumption : 120 000 kWh
Maximum Cooling Demand : 9 000 kW
Cooling Energy Stored : 25 000 kWh
Store Type : STL - 00 - 448
Number of Tanks : 8

Characteristics

The STL is used to shave the peak demand between 8 h and 19 h. The STL is comprised of 8 tanks in parallel. The STL is charged during the night by 3 chillers (2 500 kW at -5.5/-1°C).
The STL allows the Ministry of Finance to save on the operating costs and to have a back-up system.
