Located in downtown Edmonton, ICE District is a new, mixed-use sports and entertainment district and the largest of its kind in Canada. The Edmonton Tower is a 27-storey office tower with a 3-storey podium and 24 office floors. The main floor will provide tenants with service retail, a bank, and a cafe. The second floor includes conference space and common meeting and training rooms. The fourth floor will feature a daycare and an outdoor terrace and green roof. The tower also includes a four-level underground parking structure for over 2,500 cars. Sustainability is a key feature for the ICE District project, with Edmonton Tower targeting LEED Gold certification. Smith + Andersen were also involved in Block A (JW Marriott Hotel and Legends Private Residences), Block G (residential tower and 300,000 square foot retail podium), the ICE District parkade (2100 car underground parking garage), and Block E (peer review of the 60-storey office and residential tower).
The construction documents for this project were produced using BIM, with various levels of content development. The majority of the mechanical systems were developed to level 300, which indicates a level of detail in which the model element may be graphically represented as a general system, object, or assembly with approximate quantities, size, shape, location and orientation. The mechanical room was developed to level 350. A key advantage to using BIM for the project was the ability to coordinate the mechanical system within tight ceiling spaces.
Tower D is a unique building mechanically and incorporates many energy saving features. Perhaps the first of its kind in Canada, Tower D utilizes chilled beams for the interior and variable flow non-condensing fan coil units with electronically commutated motors (ECM) on the perimeter. The rational for this system evolved from a need to reduce the size of the core and manage building height, which we managed successfully (the building was almost fully leased before construction started). A conventional variable air volume (VAV) system did not fit well with the steel structure and economics weren't working well for the owner, the resulting system was costed and we also looked at the implications to the tenant. Chilled beams offer ideal comfort conditions to the interior zones by maintaining constant ventilation rates which can't be achieved with VAV boxes. VAV boxes throttle back the supply air to meet the zone load whereas with chilled beams, the chilled water is throttled and the air volume stays the same. Primary air is dry and drives the induction process in the chilled beams.
The perimeter system, using non-condensing fan coil units with variable flow capability, satisfy the variable type load experienced on the perimeter by throttling both water and air to satisfy the set point. Outdoor air is delivered to the fan coil units (FCU) such that only this amount of air is reheated and not the minimum ventilation rate for the space. The variable flow and dedicated outside air delivery gained energy points towards the LEED Gold target. Other building system features include: energy recovery, CO2 sensors, storm water retention, condensing boilers, high-efficiency chillers, and metering.
