Solar cooling technologies transform solar radiation to provide space cooling and refrigeration services. Air conditioning in buildings has traditionally been provided by air conditioners using electrically driven vapour compression chillers. These are responsible not only for GHG emissions, but also use CFCs and HCFCs and related compounds as refrigerant fluids, which also contribute to climate change and are known to deplete the ozone layer.

Project developers of solar thermal energy projects in the CDM pipeline mainly apply the following methodologies:

ACM2 “Consolidated baseline methodology for grid-connected electricity generation from renewable sources”
AMS- I.C. “Thermal energy production with or without electricity”
Further information on these metholodogies can be found here.

As of 1 February 2010, there are 10 solar thermal projects in the CDM pipeline - 5 areregistered and 5 are at the validation stage. [media:image:7]

Example CDM project:
Title: Federal Intertrade Pengyang Solar Cooker Project (CDM Ref. No. 2307)
The Federal Intertrade Pengyang Solar Cooker Project is located on the dry land of southern Ningxia in northwestern China. Implemented by Ningxia Federal Intertrade Co., the proposed project will install 17,000 solar cookers for the poor rural residents in mountainous areas with a rural population of 92,331 (or 20,341 households). The project will cover 83.6% of the households in the project region. The rating power of each solar cooker is 773.5 W and the total capacity of the proposed project is 13.1 MW. The proposed project will enable the rural residents to efficiently substitute solar energy for the fossil fuel (coal) used in daily cooking and water boiling - avoiding CO2 emission that would be generated by fossil fuel consumption.
Project investment: USD 900,000 million
Project CO2 reduction over a crediting period of 10 years: 357,230 tCO2e
Expected CER revenue (USD 10/CER): USD 3,572,300

GeneralSolar termal heating anc cooling technology was utilized in the 2008 Olympic Summer Games. Two separate systems supplied the Olympic sailing center in Qingdao with solar energy. The logistics center was equipped with a solar system for solar cooling, heating of warm water and supplying of energy to the heating system. Operations of the unit, encompassing a collector area of 638 m² /6,867ft², had already begun in 2006.Concurrently, 666 m²/7,169 ft² of collectors for heating the swimming pool, heating of warm water and supplying energy to the heating system, was installed in the Sports Center. The unit on top of the Sports Center captures everyone’s eye owing to its breathtaking architectural design.

TechnologyThe energy generated from a collector area encompassing 638 m²/6,867 ft² on top of the Logistics Center is fed to a buffer store, which holds a capacity of 12 m³/3,170 galUS. Two absorption cooling units are powered by this energy stored in the buffer store. Furthermore, the energy is used for the heating of warm water and, in case heating is required, to supply energy to the heating  system. The facility is coupled to a district heating supply to care for peak loads. After feeding the solar energy of the SportsCenter (with a collector area of 666 m² /7,169 ft²) to two buffer stores, which have a capacity of 7m³/1,849 galUS each, the energy isprovided for heating the swimming pool, heating of warm water and to supply energy for the heating system.


Collector area: 1,304 m²/14,036 ft² totalStorage capacity: 2 x 7 + 12 m³/3,698 + 3,170 galUSCapacity of cooling unit: 545 kW (155 tons)Capacity for auxiliary heating system: max. 700 kW (200 tons)Capacity for heating of warm water: max. 150 kW (43 tons)Commissioned 2008
