Building Specifications

Typical floors are be conditioned by compartmental Variable Air Volume (VAV) handling units. Each compartmental air handling unit is supplied with the required outside air volume through a pressure independent, variable volume terminal unit at each floor. The HVAC system provides the following features:

  • Variable frequency drives for each compartmental handling unit to reduce energy consumption
  • 2-stage filtration; pre-filters will be rated for MERV 6 and final filters will be rated for MERV 13
  • Overhead air distribution with one local temperature control unit per 450 square feet for perimeter zones and one control unit per 900 square feet for interior zones. Perimeter zones shall be provided at each structural bay and at each corner of the floor plate
  • Linear ceiling diffusers for distribution of conditioned air along the perimeter zones
  • Constant volume ECM fan powered VAV boxes equipped with heating water coils located at the windows provide perimeter heating while VAV terminal units will sequence control of heating valves to avoid simultaneous heating and cooling

To reduce energy consumption, the large southern exposure of the building provides interior illumination through the utilization of natural day-lighting. When natural light is not adequate, the lighting system is designed to use minimal energy by incorporating high efficiency fixtures that provide both adequate lighting to the occupants and a reduced lighting power density (LPD) throughout the building. Microprocessor lighting controls are used for the lighting of the Building from a central master control unit having field distributed control panels for local zones and local switches. The lighting control system has the following features:

  • Programming functions at the central master control unit with zone control programming delegated to field control panels as operationally required
  • Display status of lighting controls and operations, including local control devices
  • Local low voltage switches accessible near the elevator lobby of each floor, with central control provided by master control unit
  • Lighting control zones with relays as required to suit tenants’ requirements will be provided during the fit up of the space
  • Local switching control for individual room and suites to have integral occupancy sensor
  • Daylight harvesting will be provided for the fixtures located within 4.5m of the perimeter of the space


  • Electrical capacity services each floor with at least five (5) watts per usable square foot, demand load, which will be in addition to any watts needed to operate the base building equipment, including HVAC
  • An emergency power system is provided in accordance with the requirements of the Ontario Building Code and any applicable Provincial and Municipal Codes and Regulations
  • A separate 500 kW tenant generator is installed in the penthouse complete with automatic transfer switch and tenant emergency distribution panel. Distribution from the tenant generator located in the penthouse to the tenant’s floor is the responsibility of the tenant. The tenant emergency power distribution will be capable of providing up to 50 kVA of UPS loads plus cooling equipment associated with the IT loads with a 25% growth factor
  • All electrical systems comply with the Model National Energy Code of Canada for Buildings


  • The building is served by two (2) separate telecommunications service entrances capable of receiving service from multiple telecommunications vendors to a single telecommunications room
  • Tenants are provided with dedicated sleeves between the stacked telecommunication rooms to run their telephone, data and satellite transmission cabling to equipment located in the applicable telephone and/or data equipment closets or other areas of the building designated for such purposes. Tenants may elect to have dedicated communication risers (copper or fiber)at the tenant’s sole cost to install such dedicated riser cable from the main Demarc directly to the tenant’s data center


  • Six (6) passenger elevators of minimum 3,500 lbs capacity and 700 FPM will be provided to serve all office floors
  • One of the six elevators services all three levels of underground parking and all floors of the building with 5,000 lbs capacity
  • Two (2) passenger elevators, with 3,000 lbs capacity (500 FPM), will be provided to serve all parking levels to the seventh floor
  • All passenger elevator cabs are designed to reflect the materials and finishes used in the ground floor lobby and each cab utilizes centre-opening doors
  • Elevator control panels are located at the security desk and have the capability of adding security card access
  • Tenants have the ability to tie-in to the existing building security system and/or install their own security system within their premises at their own cost
  • Tenants may install card readers with electronic door locking devices and intercoms and (subject to applicable code) upgrade finishes at stair shafts to allow the tenant to use fire stairs for vertical circulation between floors
  • Provided the tenant chooses a compatible system to the building security system, the tenant will be able to retain control and responsibility of programming and issuing security cards to its employees
  • 150 Elgin has Destination Dispatch – a new concept in elevator controls designed to help you reach your destination faster.


Performance Court – 150 Elgin is LEED Gold Core + Shell certified and BOMA BEST Gold Certified.

  • Healthy indoor work environment: To promote the comfort and well-being of building occupants and to prevent indoor air quality problems, a stringent Indoor Air Quality Management Plan was implemented and enforced. The ventilation system utilizes occupancy & CO2 sensors to control the ventilation system and maintain indoor air quality and proper ventilation levels while also saving energy.
  • Reduced energy use: To reduce energy consumption, the southern exposure of the building provides interior illumination through the utilization of natural day-lighting. When natural light is not adequate, the lighting system is designed to use minimal energy by incorporating high-efficiency fixtures that will provide both adequate lighting to the occupants and a reduced lighting power density (LPD) throughout the building.
  • Water reduction and appropriately recycled water usage: The largest use of water in most facilities is landscape irrigation. The 150 Elgin landscaping plan consists of native adaptive species that are drought-resistant to the Ottawa climate. Water usage is further reduced through the use of water-efficient plumbing fixtures as well as integrating a rainwater cistern to collect storm water from the roofs. Views of building’s “green” roof terraces are an amenity for occupants as well as visual benefit.
  • Waste diversion programs: A comprehensive waste management policy & program was implemented for the building and site. Recyclable waste is diverted to the appropriate recycling facilities. These initiatives will reduce the environmental impact of the property by addressing ongoing consumable, electronic, and construction alteration waste stream.
