Grand Opening of World's Largest Hospital SolarWall¨ (solar air heating) System

The largest hospital SolarWall¨ system in the world was installed at Cambridge Memorial Hospital (CMH). Totalling over 10,000ft2 in size (spread over 3 sections) the CHM SolarWall¨ systems will reduce the traditional heating load by using the sun's energy to preheat the incoming ventilation air.

Cambridge, Ontario, Canada; May 21, 2009 - The largest hospital SolarWall¨ system in the world was formally unveiled today at a special ribbon-cutting ceremony at Cambridge Memorial Hospital (CMH).


Totalling over 10,000ft2 in size - spread out over three sections - the CHM SolarWall¨ systems will reduce the traditional heating load at the facility by using the sun's energy to preheat the incoming ventilation air. This will result in annual CO2 displacement of approximately 200 tons.

The SolarWall¨ project at CMH was part of an overall energy savings and facility renewal program in partnership with Honeywell which also included control upgrades by Honeywell. Conserval Engineering designed and supplied the SolarWall¨ system.

Julia Dumanian, President and C.E.O. of Cambridge Memorial Hospital addressed the media as the morning sun shone on one of the hospital's three SolarWall¨ systems. "Yes we ordered the sunshine especially for this event, to show how we are going to use the sun to reduce our energy costs. This is truly an exciting day in the life of this hospital and this community... and in fact, this country. What we see around us " and above us " are three SolarWall [systems] that will make a difference to future generations."

Ms. Dumanian also spoke about how the substantial cost savings from the SolarWall¨ systems will be re-directed towards patient care. "Energy savings at Cambridge Memorial Hospital have a direct impact on operating costs and service delivery. The Solar Wall you see here and on two walls in the back, were selected based on sun exposure; ease of allowing heated air into the hospital air-handling system; and payback within six years. The overall Energy Saving and Facility Renewal Program " financed partly through grants and incentives " will yield an annual guaranteed utility and operational savings to the hospital of more than $160,000. With utility and operational costs rising, reducing energy costs is a sound investment in the hospital's future."

The keynote speaker at the ceremony was Federal Minister of State for Science and Technology, Gary Goodyear, who is also the local MP for Cambridge. He spoke about the Federal Government's commitment to spearheading the use of solar technology, and how growth in clean technology is also driving local economies.

This is the second hospital project that Conserval Engineering and Honeywell have partnered together on to deliver a SolarWall¨ solution.
