Designed by NORR Ltd. / MTBA Architects & Associates CERTIFIED APRIL 2016

The Bank of Montreal Renova2on is a 3-‐storey, 4,867m2 office and conference building located at 144 Wellington St. in OYawa, ON. The renova2on is an addi2on connected to the original Bank of Montreal heritage building and is now home to large parliamentary mee2ngs and func2ons. By earning the highest possible ra2ng (5 Globes), this project surely serves as a na2onal or world leader in energy and environmental performance. A sustainable contribu2on to the community The Bank of Montreal Renova2on building was able to incorporate many energy-‐efficient and environment-‐friendly features including a green roof, energy-‐efficient lights and sensors, low-‐flow faucets and toilets, HVAC energy management, and more. The team was also able to reduce the overall embodied energy of the project through efficient transporta2on and by taking advantage of the exis2ng materials from the original Sir John A. Macdonald building. Reuse of limestone and other materials were used to repair the masonry and refurbish the interior, as well as re-‐appropria2on ini2a2ves of former marble tellers’ counters and benches. Through an Integrated Design Process (IDP), Environmental Purchasing strategy, and Commissioning Plan-‐Documenta2on process, the project was able to bring together various stakeholders and prepare strategies that successfully reduce waste, conserve energy, and minimize the environmental impacts of the Bank of Montreal Renova2on.

Mee2ng future needs Knowledge of the microclimate of a site can influence decisions regarding building placement and orienta2on, building design, and landscape features. This can include measures such as those to reduce the urban heat island effect or “light pollu2on” of the night sky. This project has taken ini2a2ve to address many of these contemporary issues. The green roof is accompanied with high albedo materials to help reduce unnecessary excess ambient heat in the city while offering a natural habitat for birds and other small animals. The green roof will also help with rainwater management by absorbing water and reduce runoff. In addi2on, obtrusive aspects of exterior ligh2ng such as light trespass and sky glow were me2culously avoided to preserve the nocturnal sky. Overall energy consump2on is an important ini2a2ve and is in line with Canada’s na2onal energy targets for coming years. The Bank of Montreal Renova2on has been designed to perform 21% beYer than the Model Na2onal Energy Code for Buildings reference, and has an es2mated energy use of 9,176 GJ/yr.
