Presentation Overview

The technical theme for the evening will be Radiant Heating and Cooling Systems for commercial applications.

Radiant heating and cooling installations are becoming more common in commercial buildings within North America and are in a growth pattern. Emerging from this is the hybrid radiant + HVAC system.  A combined system of radiant plus air which offers a number of advantages, including improved indoor air quality, improved thermal comfort, less draft/noise, significant energy savings and smaller HVAC equipment requirements.

The heating and cooling sources for radiant systems are most often provided by boilers and chillers; however an increasing number of installations are being connected to ground source heat pumps.  Since radiant heating and cooling systems typically use large surface areas such as floors, walls and ceilings as the output source, the supply water temperatures needed to heat and cool the space can be lower and higher respectively, compared to traditional water temps for HVAC fan coils.

The key advantage of low temperature heating and high temperature cooling is the improved efficiency of the heating or cooling source.  Geothermal systems operate within the ideal supply water temperature ranges for most radiant heating and cooling applications so they are a natural fit with radiant systems.

The presentations look at the various components of a radiant heating and cooling system, highlighting the key advantages of this type of system vs traditional HVAC. Examples of commercial projects across Canada will be showcased where radiant heating and cooling systems have successfully been installed using ground source heat pumps as the primary heating and cooling source.

When it comes to making a case for a sustainable system, having a sound financial argument to back up the sales pitch for an environmentally-conscious option makes the sell that much easier. When the estimated payback on a conventional borehole geothermal install for Walmart Canada’s 135,000 square foot sustainable prototype Supercentre in Burlington, Ontario started to approach 40 years, the merchandiser asked engineering firm Stantec to explore ways to make the environmental commitment more financially viable.

Stantec’s solution, the use of SpiderPlow technology, was inspired by the oil and gas industry where this type of pipeline installation is more commonly used as an alternative to traditional open trench options. Going this route helped drop the payback for the entire HVAC system down from 40 years to eight – well within the client’s expectations and comfort zone.

In addition to the geothermal system, Stantec developed strategies and innovations to further reduce the capital cost and make geothermal a more attractive option on future projects for the company.
