A presentation delivered by New Leaf Power and Conservation Solutions Limited on March 6, 2017 at the Sea Water Air Conditioning in the Caribbean Workshop at the Caribbean Development Bank.

1. District Cooling in Canada and Jamaica –
Precedents and Prospects

2. 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.

4. 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.

8. SWAC PRECEDENTS IN CANADA
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

10. Precedents in Canada Cont’d
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.

14. 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.

15. 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
