The building reflects the requirement by Marriott to create 2 distinct brand hotels in separate buildings but to have the advantage of shared amenities for parking, conferencing, food service and guest amenities. Thus the lower portion (podium of the building) up to and including the 2nd floor are common to both buildings and then each tower is separate for the applicable brand hotel. Residence Inn for long stay guests with interior living amenities similar to an apartment and Courtyard Inn for short stay / higher quality feature guests.
This 204 room 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 by a 11,000, two storey common amenity area that features a spa, pool and fitness area. Housekeeping and commercial kitchen areas are also centralized, in order to provided 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 building sustainability. HRV’s and staged mechanical systems were incorporated in the building to decrease energy use and improve sustainability. Occupancy control systems were provided on unit by unit heat / cool systems to provide most effective and efficient use suite mechanical systems.
The project was undertaken using 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 to ensure appropriate constructability of the wall and eliminate potential failures that would occur in penetrating an internal Vapour barrier.
