Frequently asked questions

CLIMESPACE in 20 questions

1- Is the supply of cooling available year round?

CLIMESPACE ensures the supply of cooling 7 days a week and 24 hours a day all year round. During 2020 continuity of service stood at 99.993%

2- What does the connection to the CLIMESPACE district cooling system include?

The CLIMESPACE contract includes:
  • installation of the outgoing and return pipes that connect the building to the energy supply network infrastructure located beneath the roadway
  • all equipment necessary for delivery of primary energy in the building’s utility room designated for CLIMESPACE: exchanger, electrical control panel etc.
  • supply of cooling energy from the generating plant to the delivery building.

3- How is the connection done?

The connection is carried out by technical teams supervised by CLIMESPACE project managers.
  • The Network Division, in charge of the public right of way connection from the CLIMESPACE network infrastructure to the private areas of the destination building.
  • The Substation Division, in charge of connection and delivery in the private areas, for the substation installation and commissioning in the destination building.

4- How long does it take to connect a building?

Connection to the CLIMESPACE district cooling system requires a technical feasibility study subject to several regulatory constraints. This study takes from 10 to 14 months, a period that cannot be shortened as it relates, in particular, to the administrative permits that have to be obtained from various bodies (Paris city hall, etc). Therefore, the minimum connection period is 10 months.

5- How does the network enter the building?

The CLIMESPACE network circulates mainly via the sewers of Paris, which is why the network enters primarily through “special connections” in the sewer of the buildings concerned. Where this is not feasible, it enters through the ground.

6- What about the obsolescence of CLIMESPACE equipment and facilities?

The CLIMESPACE solution provides a full guarantee of your cooling installations: all parts and labour needed for replacing or maintaining the equipment, or the entire substation, are included in the package.

7- Is there a minimum power capacity level to subscribe to?

CLIMESPACE is able to equip all types of premises, even the smallest. Today, the company’s experience enables it to meet the specific needs of small surface areas. Through shared installations, district cooling actually makes it possible to provide high quality cooling in small-size locations, with possible use of more compact equipment adapted to the size of the premises. CLIMESPACE does however set a minimum connected load limit of 50 kW.

8- Can the capacity contract be changed over time?

For 3 years, CLIMESPACE guarantees the option of increasing the capacity within the range established in the initial contract; dedicated teams are available to make regular visits to all customers to optimise their contracted capacity in accordance with their needs.

9- I am a CLIMESPACE customer: if I have any technical questions about my equipment, who do I call?

For any technical questions, a User Relations Manager is available by phone at (+33) 1 40 02 79 43 or by email at

10- How can I contact CLIMESPACE in an emergency?

In case of an emergency, an on-call number is available for customers 24 hours a day 7 days a week. The number is (+33)1 40 02 78 78.

11- How does CLIMESPACE set its prices? Do prices remain stable over time?

As a City of Paris concession holder, CLIMESPACE tariffs are set by the latter. The continuity of CLIMESPACE’s policy in terms of energy efficiency as well as its power purchasing policy allow it to moderate the effect of tariff increases: between 2014 and 2020, CLIMESPACE tariffs increased by only 1.1%. When in 2020 the electricity tariff increased by almost 8.7% (electricity sold to final consumers INSEE 001653959), the CLIMESPACE tariff increased only by 3.8% for consumptions (R1) and 2% for the subscription. CLIMESPACE operating costs, by contracted power range, break down as follows: - A fixed annual subscription (R2) which includes: renewal of equipment, handling of end of life equipment; maintenance and full warranty of parts and labour; cold production, network and energy transfer stations equipment up to the contracted power level; 24 hours a day monitoring and management, 365 days a year, energy transfer stations and production sites (by GTC and ADSL line); on call service 24 hours a day, 365 days a year for the primary CLIMESPACE installation; appraisal of the customer’s secondary installations connected to CLIMESPACE and advice on optimising the customer’s secondary network from an energy-saving perspective; management of production related regulatory and environmental risks. – Monthly costs, commensurate with energy and water consumption (R1) – For a CLIMESPACE network connection, a portion of the infrastructure investment will necessarily need to be taken into account and will be conditioned on the findings of a technical feasibility study; this investment is intended first of all to participate in financing the work required for the production/distribution of cooling energy (connection fee and R’2) and secondly to deal with any technical uncertainties arising from the hydraulic connection or the distance between the building and the CLIMESPACE servicing area (assistance fund).

12- How is CLIMESPACE environment friendly?

As a collective solution, with its attributes of efficiency, the district cooling system addresses with intelligence the demand for cooling in a dense urban environment: Energy efficiency: energy consumed to produce cooling is greatly reduced Environmental efficiency: locally available natural resources are utilized Shared resource efficiency and clean energy solutions: all environmental, health and aesthetic drawbacks are minimized, compared with an equivalent infrastructure of stand-alone air conditioning installations. In Paris, the district cooling system results in: 50% more energy efficiency 35% less electricity consumption 50% lower CO2 emissions compared with an equivalent infrastructure of stand-alone installations. Finally, since 2013, CLIMESPACE initiated a responsible approach for purchasing electricity to power its production facilities, guaranteeing it is 100% from renewable sources.

13- What is CLIMESPACE's position about environmental certifications?

CLIMESPACE solutions contribute to qualifying for certifications (HQE, BREEAM, LEED, etc.) that distinguish green buildings. CLIMESPACE can help customers: reduce the impact of refrigerants on global warming, establish an environmental policy, or assess a building’s financial performance through life cycle analysis. CLIMESPACE solutions eliminate the presence of fluids in buildings thanks to production outsourced to external sites, comply with a plant’s minimum fluid leakage rate (1.21% in 2020), and integrate an installation’s maintenance and end of life costs over the contract life.
