Edgewater Casino

The Edgewater Casino is a 70,000 ft2 two-story casino that opened to the public in February 2005, and features 500 slot machines and 60+ gaming tables. Located in Downtown Vancouver’s inner harbor, Edgewater Casino brought new life to a building that had been built for Expo ’86 World Fair but had stood vacant for several years.

The Challenge

The owner, Edgewater Management Inc. wanted to create a contemporary gaming facility that would integrate into the urban, downtown location while maintaining an interior experience that is consistent with a glass building. Paramount to the owner was to provide an environment with the highest level of thermal comfort and indoor air quality for its patrons and employees to enjoy. It was also critical to deliver exceptional energy efficiency, all the while maintaining the inviting atmosphere.

The existing glass structure with vaulted ceilings and limited mechanical systems was considered to be unsuitable for a casino which, traditionally, has no natural light and totally enclosed interiors. The fact that the skin of the building was 90% glass posed a large problem to the design team. The solar heat gain in the space was enormous. This, combined with the building’s vaulted ceilings, required innovative solutions both mechanically and architecturally. Patrick Cotter Architect led the architectural and interior design of the space, while Broadway Refrigeration teamed with VEL Engineering to design the mechanical system. Together, they would design one of the most innovative HVAC solutions the west coast had ever seen.

Design Team Profile

Cobalt Engineering

Since its inception in Edmonton, Alberta in 1957 Cobalt Engineering—formerly VEL Engineering—has attracted talented engineers from around the world whose experience and training has put them at the forefront of sustainable design practices and technologies.

While being green has only recently entered the collective consciousness of North America, at Cobalt sustainability has been a part of their design approach for well over a decade. With expertise in sustainable technologies including variable refrigerant flow, geo-exchange systems and passive design systems, Cobalt has been appointed as members on Urban Design Panels, is a sustainability consultant on policy guidelines for the City of Vancouver and the Canadian Green Building Council, and has been involved in local and international award-winning projects.

Patrick Cotter Architect Inc.

Patrick Cotter Architect Inc. is a firm that has carved its reputation from its sensitivity to context and its commitment to designing for community. The firm’s expertise rests in the creation of master planned communities in a variety of settings, from high density city centers and urban villages to pedestrian-scaled townhouse neighborhoods with strong street character, complete waterfront communities, suburban and rural residential communities and resort properties.

With experience in a broad range of building types, a team of qualified architects and technicians has allowed Patrick Cotter Architect Inc. to create a body of work in Canada and the United States that includes commercial, residential, and mixed-use projects ranging from wood frame townhouse and condominiums to high-rise residential towers. Other areas of expertise include resort, hospitality, and care facilities. This talented team works in a range of architectural idioms, is able to adapt to the unique requirements of every project and site with an appropriate and highly contextual response.

Price Solution

Due to the building’s large vaulted ceilings and the requirement for exceptional indoor air quality, thermal comfort and energy efficiency, it was determined that a hybrid displacement system was necessary for this project. The system would include a floor displacement system in the lower space where the slot machines would be installed, and a low level sidewall displacement system on the upper level where the gaming tables were to be located.

A displacement system would supply cool, conditioned air at a low level in the space, which would then permit the heat given off by the equipment and occupants to warm the surrounding air, causing it to rise and be replaced by the cool supply air from below. By pooling the supply air on the floor and having it pulled into the thermal plumes caused by heat sources, it naturally gravitates to the areas which need cooling or ventilation. The higher supply air temperatures characteristic of displacement ventilation systems, in this case between 65º and 69º F, extend the system’s free cooling band significantly, leading to a corresponding reduction in energy consumption.

Design

The use of a raised floor system on the main floor would allow the slot machines to be easily relocated when desired. Designed to be used with raised floor systems, the Price ARFHD displacement diffuser was selected. This concept would also eliminate most of the duct work in the building and create a low pressure system that further increased energy savings.

During preliminary design, it appeared the high air volume required by the space would require the use of large diffusers that would potentially conflict with the ability to attain a smooth, seamless aesthetic. Price reconfigured a product that was designed to an 8" x 48" maximum size, making it suitable for this application in the sizes required, up to 36" x 72". With such large diffusers, they would have to be integrated into the interior design of the space. The design team was impressed with the DF1R’s ability to blend into room elements, as it was originally designed to integrate into a stair riser or baseboard.

Schedule

Because of the tight construction schedule, Price was asked to supply the 1300 floor displacement diffusers and 220 wall displacement diffusers with a very short lead time. Price responded by having the original order of 200 wall diffusers on site in two weeks and a second order of the diffusers on site one week later. The floor displacement diffusers were installed in precut floor tiles supplied by the flooring manufacturer. DF1Rs were installed throughout the space in wooden cabinets, serving as supply plenums. As a result, the system was essentially self-balancing.

Today

The displacement system installed in the Edgewater Casino continues to perform beyond the expectations of the design team. "This system provides a consistent high level of thermal comfort and indoor air quality from one corner of the facility to the other. Even though large volumes of air are being delivered, draft is not a problem." ~ Albert Bicol, Cobalt Engineering.

The Edgewater Casino is an excellent example of an integrated design process where the contractors, engineers, architect and product manufacturers collaborated to create a building that exceeds everyone’s expectations. Edgewater Casino, with its innovative displacement system, demand ventilation, double skin, low-pressure mechanical system and energy efficiency raises the bar for the design of public buildings and open spaces.
