R290 refrigerant gas uptake for ACs & centrally-cooled buildings: R290 split-unit ACs are not only far more energy-efficient (20% more compared to conventional split-unit ACs), but lead to lower GHG emissions from fluorinated refrigerant leakage.
Direct/Indirect Evaporative Cooling uptake: The lowest annual energy consumption and GHG emissions per unit area of cooled space in hot and dry regions is achieved through the use of direct as well as two-stage (direct/indirect) evaporative cooling when compared to the business-as-usual options of unit ACs or central AC systems.
In this technology, naturally cooled water (from a ground or surface water source) is circulated through ceilings or floors by means of a simple plumbing system consisting of pipes & channels.
Vapour Absorption chillier machines (VAM) produce chilled water using a solar source rather than electrical input as in the case of vapour compression cycle.
Besides the above active (machine) cooling technologies, the project will also promote passive cooling technologies and design approaches in buildings. The more prominent amongst these are: Roof and Wall-Insulation, Radiant Barriers / Night-Sky Radiation Systems that shield roofs from solar radiation during the daytime and promote rapid heat dissipation through radiation at night using retractable low-emissivity radiant barriers and high-emissivity roof coatings, Efficient Fenestration Systems such as Engineered Glazing and Double-Glazed Units, Shading Devices, and Spectrally Selective Window Films.
