National Ozone Unit (NOU) in the Energy Division of the Ministry of Finance and Energy in conjunction with the global programme “Cool Contributions fighting Climate Change” (C4) request for suitable demonstration sites for evaluating the energy performance of R-290 (hydrocarbon) split air-conditioning units


The project Cool Contribution Fighting Climate Change (C4) is making available to the private sector in Grenada, a total of six (6) climate friendly split air conditioners for demonstration purposes. The objective of this initiative is to evaluate the energy efficiency of these R-290 Split AC units (12,000 BTU and 18,000 BTU cooling capacity) and to promote the use of natural refrigerant technologies in Grenada.

This project is being implemented by the National Ozone Unit (NOU) in the Energy Division of the Ministry of Finance and Energy, in conjunction with the Deutsche Gesellschaft fuer Internationale Zusammenarbeit (GIZ) GmbH, as part of the global programme “Cool Contribution fighting Climate Change”, funded by the German Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) as part of the International Climate Initiative (IKI).

The general objective of this is to promote the use of energy-efficient and climate friendly air conditioning appliances while increasing the availability of natural refrigerants such as, R-600a and R-290.

The project now invites eligible private sector entities to submit Expressions of Interest (EOI) giving consideration to the following criteria.

Private sector entities shall be eligible to participate if:

  • Adequate space requiring cooling is available
  • Solid ceilings (concrete, drop or tiled) and walls
  • The room should already contain only one working AC unit of similar size (either 12,000 BTU or 18,000 BTU)
  • The private sector entity has technicians trained in flammable refrigerant technology (hydrocarbons)
  • Up to date data or records on the existing AC is available
  • The room meets the minimum area and installation height for the charge size of the AC unit.
    • For the 12 000 BTU unit[1] the room size shall be at least 17m2 (with minimum installation height of 1.8 m)
    • For the 18 000 BTU unit[2] the room size shall be at least 23m2 (with minimum installation height of 1.8 m)
  • The following should be considered for the indoor unit:
  • There shall be no electric appliance, power switch or socket under the indoor unit.
  • There should be a minimum distance of about 1 m from TV-sets or any other electrical appliances.
  • The air inlet and outlet vent should not be obstructed, make sure that the air can be blown throughout the entire room
  • Ready to actively participate in the promotion of climate-friendly green cooling:
  • Providing information and access to the equipment for public awareness and promotional purposes
  • Make available for the general public information
  • Participate during outreach events and stakeholder consultations
  • Provide a mechanism for data collection, monitoring and servicing of the equipment throughout the appliance’s lifetime.

Private sector entities shall not be eligible to participate if:

 The presence of strong heat sources, combustible gases, vapors or volatiles substances are present in the room

  • The environment possess high frequency waves, e.g. by radio equipment, medical or welding equipment
  • Places with very contaminated air (such as places with oil containing air)

Expressions of Interest must be received no later than, 04:00 pm (Eastern Caribbean Time) on Friday 30th March, 2018. Submission shall either be in hard copy or in electronic format in the form of a PDF document sent to the address or email below:
