District Cooling in Canada and Jamaica –Precedents and Prospects

New Leaf Power- Background

New Leaf Power & Conservation Solutions Limited is a full service energy solutions

company serving Jamaica and the Caribbean. The Company won a Climate Change

Innovation Award from the World Bank for it work developing an solar energy hub

for an offshore fishing island off the cost of Jamaica on the Pedro Banks.

NLP has partnered with Bluerise to explore the development of Cooling Districts in

the Northern Caribbean in general; Jamaica in particular.

The Cayman Trench

The Cayman Trench, Bartlett Deep, or Bartlett Trough is a submarine

trench on the floor of the Caribbean Sea between Jamaica and the

south-eastern tip of Cuba. The trough has a maximum depth of

25,216 feet (7,686 m) with near freezing temperatures; the deepest

point in the Caribbean Sea. Paradoxically, some of the world’s hottest

(up to 400 degrees Celsius) and deepest deep-sea vents are found in

the Cayman Trench some 5 km (3.1 miles) below the surface of the

sea.

Enwave:

•Deep Lake Water Cooling (“DLWC”):

•Commissioned in 2004, DLWC anchors Enwave’s district cooling system

•DLWC is a renewable, “geothermal” source of cooling that allows Enwave to offer our customers several quantifiable benefits including a reduced environmental footprint and a hedge against volatile electricity prices

Purdy’s Wharf

The Purdy’s Wharf office complex sits on the waterfront of Halifax, and buildings extend out over the harbour on pilings. Cold seawater is drawn from the bottom of the harbour through a pipe to a titanium heat exchanger in the basement of the complex where the closed loop of water, cooled by the sea water, is then pumped to each floor of the building where fans blow air over the cooling pipes to cool the air.

The seawater is returned to the harbour floor. The project was jointly funded by the Government of Canada and the building’s developer, and was intended to serve as a demonstration of the technology. The project was constructed from 1983 to 1989 and consists of an 18-story tower, a 22-story tower, and a four-story retail centre. The total area cooled by the system is 65,000 sq. meters.

Cooling District Opportunities in Proximity to the Cayman Trench

Jamaica, Cuba and Cayman all benefit from access to an inexhaustible source of cold deep sea water based on their proximity to the Cayman Trench.

Undersea currents brought this extremely frigid water from the Artic thousands of years ago and the Trench has the regions coldest and hottest waters.

New Leaf Power and Bluerise have partnered to pioneer the development of this capital intensive infrastructure.

Cooling District Benefits:

• Lower cooling costs

• Predictable costs

• No Noise Pollution

• Reduced dependence on imported

fuels which require foreign exchange

• Significantly less CO2 emissions

• Climate Change Mitigation

• Reduced emission of ozone-

depleting refrigerants

• Supports protected agriculture and

cold water fish farming

• Supports innovative spa and

recreational facilities like ice rinks

and tropical ski slopes
