A modern mixed-use complex that opened in June 2014, the Tour Aimia\/Altoria<\/a> includes both commercial and residential areas, each taking up several floors. Elegant, and with a mostly glass exterior, the tower also boasts the energy efficiency of a LEED project. The commercial portion of the tower obtained LEED Canada NE Gold certification, while the residential portion qualified for LEED Canada NC Silver certification. The project ranked third in Category VI –Residential buildings – in the prestigious international ASHRAE Technology Award 2015<\/strong>.<\/span>

\n A building with many energy challenges<\/span>
\nThe project called for the design of a 35-storey tower, totalling 48,588 m2<\/sup>, of which 21,368 m2<\/sup> was intended as office space, occupying 10 floors. The residential portion occupied the 25 upper floors. A 5-storey underground garage completed the building.<\/span>
\nFrom the outset, the mechanical design engineers faced some major challenges: how to obtain LEED certification for each portion of a glass curtain wall building in Montréal, where heating degree-days total about 8,000°F a year?<\/span>
\nA vision of the whole was needed to combine the comfort of the occupants with the energy efficiency of the complex. To successfully address local issues, it was necessary to think globally. The following approach was therefore proposed to the client.<\/span>

\nIn a mixed-use residential\/commercial project of this kind, synergies had to be optimized between office space that gives off heat (exothermic) and residential space that has 24\/7 energy needs.  <\/span>
\nTo do so, hybrid heat pumps, shared between the condos and the office space, recovered the heat exhausted from some parts of the building and returned it to the sectors that needed it.<\/span>
\nThe energy recovered from the toilets, dryers and other sources was used to heat: <\/span><\/p>\n
