By removing plume and outdoor units on buildings, (condensers, cooling towers), CLIMESPACE frees up useful space on rooftops and preserves te aestetics and arcitecture of te Parisian eritage. Equipped wit silent underground production plants separate from te buildings, te network protects te surrounding areas from te noise pollution caused by running macines, te network also limits te rise in local temperature («oasis» effect). Greater security, less SANITARY risks CLIMESPACE as developed a genuine strategy to control ealt risks, wic ensures te reliability and safety of its facilities. CLIMESPACE offers every guarantee to eliminate te risks of bacterial contamination generated by running cooling circuit for air-conditioning systems, suc as strict compliance wit ealt standards and regulations, pysically separating fluids, sanitary treatment, tracking cooling fluids, service continuity. By coosing CLIMESPACE globally you will: n Reduce global electricity consumption by 30 to 50% n limit te impact on global warming (-40% in tons of CO2 equivalent (TEWI) compared wit a stand-alone air-conditioning unit) n reduce HFC refrigerant emissions contributing to te greenouse gas effect (-70% compared wit a stand-alone unit), n decrease water consumption (-65% compared wit a stand-alone air conditioning unit) n reduce te use of water treatment products (- 80% compared wit stand-alone air-conditioning unit) A more valuable solution for te environment CLIMESPACE aims to air-condition and protect, wic is wy it as been developing urban cilled water networks for 30 years. Te result is a more ecological cooling solution, offering comfort and calm, wile improving energy efficiency. Increase well-being, decrease nuisances By coosing CLIMESPACE you elp reduce te consumption of energy resources. Centralized production reduces electricity consumption by 30 to 50% compared wit stand-alone air-conditioning units. Centralizing cooling production and using river or seawater in te condenser circuit reduces water consumption by 65% compared wit aving several stand-alone facilities.
