The Seton Marriott building is one of three runners up in the EIFS Council of Canada’s 2017 EIFS Award Competition. The building reflects a requirement by the client to create two distinct hotel brands in separate buildings while retaining the advantage of shared amenities for parking, conference rooms, food service, and guest amenities.
NORR Architects, Engineers, Planners devised a solution through the use of a podium, which comprises the lower portion of the building, up to and including the second floor, and contains the shared amenities. Above the podium, each hotel brand is housed in a separate tower—Residence Inn for extended-stay guests with interior living amenities similar to apartments, and Courtyard Inn for short-stay, hotel-feature guests.
The hotel provides 121 short-stay rooms and 103 extended-stay rooms. The short-stay rooms are grouped together over seven storeys, with dedicated amenities including a small meeting room, lounge, and business centre. The extended-stay uses are located in a six-storey building, served by meeting rooms, a 127-person conference area, and a breakfast room. The short- and long-stay components are linked together bya two-storey common amenity area that features a spa, pool, and fitness area. Housekeeping and commercial kitchen areas are also centralized to provide added operational efficiency in serving the needs of both short- and extended-stay guests.
In addition to building envelope performance improvements, mechanical system designs improve the buildings’ sustainability. HRVs and staged mechanical systems were incorporated in the building to decrease energy use and improve sustainability. Occupancy control systems were provided on a unit by unit heating / cooling system to provide the most effective and efficient use of mechanical systems.
The project was undertaken using an EIFS for the benefit of the continuity of the thermal envelope from below grade, through the podium with cavity wall insulation at the masonry, to the EIFS above at the same plane, to optimize the overall U-value of the building envelope. It was also undertaken to maintain the insulation at the exterior of the frame wall assemblies to ensure continuity of the vapour barrier assembly at the exterior of the wall and eliminate potential failures that would occur in penetrating an internal vapour barrier.
