The KPMG office tower is the first building in the long-term development of the Vaughan Metropolitan Centre - a new downtown core for the City of Vaughan initiated by the extension of the Yonge-University subway line.
This project consists of a 16-storey core and shell office building, ground floor retail, and an additional two-storey retail wing. The site also includes surface parking, an exterior civic plaza, and two-levels of underground parking directly-connected to the new Toronto Transit Commission (TTC)subway station.
In order to meet the strict energy targets required for LEED Gold certification, the building's primary heating, ventilation, and air conditioning (HVAC) systems include: magnetic-bearing chillers (with variable primary flow pumping); condensing boilers with variable secondary flow pumping on an outside air temperature reset schedule; and a variable flow 100% outside-air enthalpy recovery air handler serving compartment units with demand control ventilation. In addition, the cooling towers are capable of operating in a free cooling mode, which will meet the building's chilled water requirements in shoulder and winter seasons without the use of the chillers.
Improved indoor air quality and thermal comfort was achieved through the use of under-floor air distribution on all office floors, demand control ventilation, and minimum efficiency reporting value thirteen filters on all air handlers and compartment units. The building uses low-flow plumbing fixtures in conjunction with reclaimed rain water stored in a cistern in the parking level to minimize potable water usage. A fully-redundant condenser water system, complete with free cooling capabilities, has been provided for retail suites and tenant process loads. The infrastructure for a complete tenant metering system was also incorporated in the building design.
Electrical services include complete power distribution, fire alarm, and lighting design. The power distribution for the building is designed with a new incoming high-voltage service using two high-voltage transformers connected to a double-ended switchboard. The two transformers and double-ended switchboard are configured in a main-tie-main configuration with the tie-breaker normally open, where each transformer is sized to carry 100% of the total building load. This allows for 100% redundancy in case one of the transformers fails. The lobby and exterior lighting is designed using energy-efficient LED luminaires. The typical office floor lighting is designed with energy efficient fluorescent luminaires utilizing "quick-connect" plugs for flexibility and ease of tenant improvements/renovations during future fit-up. The exterior lighting is designed to minimize light trespass beyond the property line, ensuring compliance with LEED light pollution requirements. The fire alarm system is designed using a fully addressable, two-stage system with data gathering panels located every five floors; this allows for maximum flexibility during tenant improvements and future renovations to the office floors.
Communications services included design and construction administration for a common-structured cabling infrastructure to support an integrated building systems network. The building systems network is comprised of such systems as audiovisual, access control, closed-circuit television (CCTV) monitoring, lighting control, data and telephone.
As security design consultants, Smith + Andersen worked with the entire design team to arrive at a tailored, turn-key security system which includes video surveillance (CCTV), electronic card access control, intrusion detection, duress alarm, and an intercom system throughout the office building. The security design also includes an integrated fibre-optic, internet protocol (IP) data network, complete with IP data switches. The IP data network is designed with multiple virtual local area networks (VLANs) to facilitate implementation and integration of all security systems with the audiovisual (AV) system, lighting control system, Building Automation System (BAS), and all future building IP connected systems.
Smith + Andersen provided design and project management services to understand the client's needs and AV requirements. The AV systems were planned with an integrated design approach to connect to the common building network for building system integration. Space requirements were coordinated with the design team for head-end equipment and speakers, ensuring a final system which was both functionally and aesthetically pleasing.
The lighting design goal was to provide an energy-efficient lighting system which uses light emitting diode (LED) and fluorescent sources and is designed to the Illuminating Engineering Society of North America (IESNA) standards. The LED lighting implemented on the exterior of the building illuminates both the surface parking lot and exterior plaza/civic square space.
