Jamaica Observer / KINGSTON, Jamaica — Transport and Mining Minister, Lester “Mike” Henry has backed a five-month feasibility study for the construction of a Sea Water Air Conditioning (SWAC) System at the Norman Manley International Airport, which could begin as early as this month. Representatives of french company, Doris Engineering Group, met earlier this week with Henry at his Maxfield Avenue office and outlined the details of the study, which has already been funded from France. According to a release from his ministry today, the study will look at the airport’s current AC system, the airport environment and surrounding neighbourhoods as well as airport traffic and behaviour. Seawater Air Conditioning takes advantage of available deep cold water from the ocean to replace conventional AC systems. The system can also utilise cold lake or river water as the cold source. Previous SWAC feasibility studies indicate that electrical consumption is typically reduced by 80 to 90 per cent. Simple payback can be from three to seven years, and long term costs can be half that of a conventional air conditioning system. Henry is expected to make a presentation to Cabinet next week for final approval of the study.
