MaRS Parcel B


Designed by Adamson Associates Architects

MARS Discovery District (MaRS) is a not-for-profit corporation founded by leaders from Canada's academic, business and scientific communities. MaRS is the charitable arm of The MaRS Group, which intends to create a scientific research and development centre where the best-in-class scientific and medical and related sciences communities, including universities and hospitals, are brought together with business and venture capital to facilitate the commercialization of academic research in Canada.

The heritage building is four stories and has been retrofitted for offices ideal for small to mid-sized companies. The south tower is located behind the heritage building and consists of 8 stories of wet and dry laboratory space. The conference centre is located on lower two floors in the MaRS Parcel ""B"" South Tower. It consists of six meeting rooms, a video conferencing room, two serveries, and a 10,000 sq ft auditorium.

S + A Services Included:


The mechanical systems are designed to be flexible enough to accommodate either labs or office space in the South tower. Heating is provided by a connection to the Enwave district steam system. The project also includes a right of way for Enwave's high pressure steam line to go through the building to serve the Toronto General Hospital. Cooling is provided by cooling towers and a condenser water backbone that is capable of free cooling during the winter and shoulder seasons. The condenser water system feeds compartment room air handlers located on each floor. The heritage building is heated with radiators within a double wall and below the windows to keep the heritage façade within a consistent temperature range year round. Outside air is preheated efficiently using heat recovery wheels. Space for tenant laboratory exhaust fans are located on the roof of the South Tower


The electrical systems include dedicated tenant power riser systems and enhanced emergency power systems.
