Project Profile: The Ottawa Hospital Celebrates Green Success
- Lighting retrofits at all three campuses
- Lighting upgrade of two parking garages
- New state-of-the-art Building Automation System covering
approximately 5,500 points of control for all three
- Replacement of some chillers with more energy-efficient units
and environmentally friendly "CFC free" chillers
- Installation of high-efficiency hot water and heating
- Replacement of existing motors with more efficient
- Power factor correction to offset current low-power factor
- Sealing building envelops to reduce drafts and prevent energy
- Installation of water conserving fixtures and reduction in
process water usage
- Ongoing awareness program
The environmental impact of the project is also significant, reducing greenhouse gas emissions by 11,833 tonnes annually (equivalent to the need of 39,132 trees). The annual energy reduction is 184,279 GJ or 0.62 GJ/m2. The economics of the project show a rate of return at 12% with cost-savings at $2,546,488 for the total project cost at $17,068,531. The lighting retrofit resulted in recycling of fluorescent tubes and magnetic ballasts, which totalled 9.8 tonnes glass, 123 kg aluminum, 154 kg phosphor and 1.02 kg mercury. The ongoing awareness program will continue to facilitate better understanding of the Energy Performance Contract among employees and the surrounding community. It was estimated that the employee awareness initiative saved TOH $80 thousand based on internal metering. Staff is more aware to report about leaking faucets, overcooling or overheating in their zones and also to make suggestions to save more energy. Other hospitals began to request information about similar projects in their hospitals. NRCan with OHA organized a meeting hosted at the Civic Campus to give more information about the incentive program and the use of Performance Contracting in case they have problems with financing. TOH contribution to the community and environment was greatly appreciated.
Additional benefits of the program:
- The safety and engineering recommended levels for lighting,
indoor air quality (temperature and humidity) will be improved and
confirmed to comply with the Code after retrofitting and
implementing the energy conservation measures. The result will be a
more efficient response to building heating and cooling
requirements and better staff and patient comfort.
- TOH operators will receive training on the operation of new
- Number of hours to complete maintenance will be
- An ongoing Awareness Program will be provided to facilitate a better understanding of the Energy Performance Contract among hospital personnel, visitors and the surrounding community.
August 2005 was a significant milestone in the project when TOH and Honeywell held a staff celebration to mark the completion of the construction phase of the project. Enbridge Gas Distribution, Hydro Ottawa and Natural Resources Canada also participated in the celebration and contributed to the TOH staff energy awareness campaign. Peter Love, Ontario's Chief Energy Conservation Officer at Ontario Power Authority, was also present and said, "The program is an excellent example of how institutions can reduce their energy consumption and save on expenses, thereby lightening the load on our energy supply and on local taxpayers. The province encourages more public and private sector organizations to follow the hospital's lead." Mr. Love provided TOH with a Certificate of Recognition for their long-term commitment to conserving electricity in Ontario.
As part of the awareness program, TOH continues to participate in the National Health Care Energy Efficiency Awareness Week held each year during the first week of February. Honeywell supports this event at the three TOH campuses by promoting energy-efficiency with displays, contests, giveaways and the sharing of energy-efficiency and conservation material. This year's event focused on the "One-Tonne Challenge," encouraging hospital staff to reduce their personal greenhouse gas emissions by one tonne. Those who participated received a free compact fluorescent lightbulb to start them on their way to reducing energy at home. Hundreds stopped by to ask questions about this challenge and share ways they have been saving energy and water, both at home and at work.
As a result of the project's success, TOH was awarded the 2005 Energy Efficiency Award for Buildings, one of the Ontario Hospital Association's Green Health Care Awards. Hospital representatives accepted the award in November 2005 at the OHA HealthAchieve conference in Toronto.
