Environment Canada’s Eastgate Offices: Balancing Sustainability, Complex Mechanical Design and Comfort

New Edmonton building limits energy use with around the clock weather forecasting operations

In the cold climates of northern Alberta, forecasters at the Environment Canada building keep a continuous eye on the weather using a complex electronic system. In developing their new facility, the energy-intensive operation posed a unique challenge for architects and engineers, which was required to maintain LEED Gold standards per the federal government’s Public Works requirements.

“To ensure the building would remain fully operational in any situation, there were a lot of redundancies built into it,” said Cyrus Kangarloo, Western North American Operations Manager at Jaga. “This meant that every other facet of the building’s system would have to limit energy loads wherever possible.”

Further, parts of the building were encased in floor-to-ceiling glass – a unique feature for the cold northern territory. This made heating – and sustainable heating – a challenge.

Heating that’s Cool to the Touch

To maximize energy savings from its high-efficiency condensing boilers, engineers lined the entire perimeter of the building with Jaga’s Low-H20 products. A total of 275 Jaga Mini Freestanding and Linea Plus units were spread along the windows of three floors to heat the space. Remaining cool to the touch, these powerful units forced cold air away from the window so desks could be placed right alongside them, keeping occupants comfortable.

One of the unique features of the Jaga system is its low temperature. The units maintain an incoming temperature of 131° F degrees and a return temperature of 113° F. This allows the condensing boiler to operate as it was designed and achieve maximum efficiency even on the coldest days. In order for this to achieve the LEED rating, the convectors’ return temperatures would need to be under 120° F, so the Jaga’s products were one of the only solutions that could meet that requirement. 

“This is a great project, not only because of its energy requirements, but because of the unique building design,” said Kangarloo. “Architects typically don’t design buildings with this much in glass in this part of the country, because it is so cold. The Eastgate project shows us this is possible, and possible at low water temps.”

Eastgate has become an icon of sustainability in the region, hosting the largest solar panel array in Western Canada. The project was named Alberta’s “Top Construction Project” in the Commercial Design category in 2013.
