System Type
The
HVAC system is a constant volume, four pipe, fan coil system.
Ventilation
Rate
While
the HVAC system is operating, there is a constant volume of
ventilated air circulating throughout the premises. The ventilation
rate is designed to exceed ASHRAE requirements by 25%, providing
25 cfm per person based on an occupant load of one person
per 150 rentable square feet.
Distribution
HVAC
is distributed throughout the office areas through a
system of sheet metal ductwork and linear diffusers. Return
air is provided through slots in the lighting fixtures with
the ceiling acting as a plenum.
Zoning
The
HVAC system has a minimum of 18 zones per floor, with
each zone controlled by an electronic thermostat connected
to a Direct Digital Control (DDC) system. Individual zones
can be adjusted by adding and/or relocating fan coil units.
Basic
Cooling
The
HVAC system is designed to cool for an occupant load of one
person per 150 rentable square feet, with a lighting load
of one watt per square foot and a plug load of 1.5 watts per
square foot. Subject to availability, additional basic cooling capacity is available
at chilled water stub outs on each floor at the tenant's expense at prevailing rates.
Auxiliary
Cooling
Bentall 5 has a fluid cooler and chilled water riser to assist
tenants in providing 24-hour auxiliary cooling for computer
servers and other specialized equipment. Tenant access to
the auxiliary cooling is subject to availability. Up to
one watt per square foot of capacity is available at
the tenant's expense at prevailing rates.
Energy
Efficiency
The
HVAC system is designed to comply with the requirements
of the federal government's Commercial Building Incentive
Program (CBIP). In order to comply with CBIP, the building
mechanical, electrical and envelope systems must maintain
a high level of energy efficiency, using no more than 75%
of the Model National Energy Code energy consumption standard
for commercial office buildings.
As
a result, Bentall 5 is believed to have the most energy-efficient
HVAC system of any Class A office building in downtown Vancouver.
Greater energy efficiency translates into lower operating
expenses for tenants.
Hours
of Operation
The
HVAC system operates between the hours of 7:00 am and 6:00
pm on Monday to Friday, excluding statutory holidays, and
8:00 am to 1:00 pm on Saturdays. Additional hours of operation
are available at prevailing rates.
