Energy retrofits cut GHG emissions at Ottawa Hospital, Kingston hotel

Retrofit projects at the Ottawa Hospital and Kingston's Confederation Place Hotel and Conference Centre will together reduce greenhouse gas (GHG) emissions by more than 30,000 tonnes annually. The initiatives include a major, comprehensive energy efficiency program at the Ottawa Hospital, in partnership with Honeywell, and the introduction of innovative solar energy technology, developed at Queen's University, for hot water heating at the Kingston hotel.

The Ottawa Hospital and Honeywell have completed the construction phase of the $17-million energy retrofit program, which guarantees $2.7 million per year in energy costs savings and a reduction of greenhouse gas emissions of close to 11,000 tonnes per year. In addition, Natural Resources Canada's Office of Energy Efficiency has provided $735,275 in financial incentives to the hospital's three campuses, based on energy savings. Enbridge Gas Distribution contributed $80,000.

The project started in 2003 when the hospital and Honeywell developed a comprehensive program aimed at renewing and enhancing the hospital's mechanical and electrical infrastructure across approximately four million square feet of building space. Engineers then upgraded lighting, building control and heating, ventilation and air conditioning (HVAC) systems to more energy-efficient equipment.

"Now that the construction phase is complete, we look forward to helping the hospital exceed the expected energy savings through ongoing staff awareness and system monitoring," said Luis Rodrigues, general manager of Honeywell Building Solutions.

At the Kingston, Ontario Confederation Place Hotel and Conference Centre, patented solar-powered hot water heating technology developed by a Queen's University researcher in partnership with EnerWorks, of London, Ontario will soon be providing the hot water supply for the facility. The 94-room hotel will be the first commercial user in eastern Canada to implement EnerWorks energy-saving solar hot water technology.

The technology was developed jointly by EnerWorks and Dr Stephen Harrison of the mechanical engineering department at Queen's. The commercial-sized water heating system, which uses solar energy as its power source, will be used to heat the hotel's swimming pool, hot tub and guest room showers, as well as its kitchen water supply.

It is expected to eliminate more than 20 tonnes of greenhouse emissions and reduce energy consumption by up to 48,000 kilowatt-hours. This will reduce the hotel's reliance on traditional power by about 11%.

Rick Rooney of Quantum Energy in Kingston will be responsible for the Confederation Place installation. More information is available from EnerWorks president and CEO Mike Noble, 519/268-6500, E-mail, Web site
