TRANSCRIPT
.The William Farrell Telus Building is located in the downtown core of Vancouver, British
Columbia. This building is located at 49.11 N latitude and 123.10 W longitude. The altitude in
Vancouver is 3 meters above sea level. The mean monthly temperature ranges between 3 to 17
degrees Celsius. Vancouver's downtown street grid is skewed at nearly 45 degrees off the north
south axis; the William Farrell Telus Building complies with the governing grid of the city. The
building holds approximately 500 employees of Telus Corporate, located within the Telus
Complex. This building renovation was started in 1997. It opened in 2001-2002, with an updat-
ed gross floor area of 12,193 m² to make it a comfortable and sustainable environment.
Traditionally, the architect is responsible for initiating environmental awareness in a
design. If a design is to be "green" - sustainable elements must be explored at the preliminary
stages of the project. Often, the client has to be convinced of the positive environment and finan-
cial benefits of constructing a "green" building. In the case of the William Farrell building, the
client, Telus Corporate Telecommunications mandated that the renovation to their head office be
renovated to make it a sustainable, environmentally conscious design. Considerations to improve
the work environment were to be incorporated wherever possible.
Telus, as a company, adheres to strict environmental ideologies. Their Environmental
Policy enforced by the Telus Investment Recovery operations, in 2001, generated revenue of over
4.8 million and differed over 17,024 metric tons of waste from landfill sites. This was achieved
through the sale of used and surplus equipment, the recycling of lead acid and dry cell batteries,
the recycling of phone directories, and through the use of video conferencing, which saves on
travel costs and CO2 emission fumes reducing greenhouse gases. Their environmental respon-
sibility and awareness as a company is unique - Telus is the only North American
Telecommunications company to be included in the Dow Jones Sustainability World Index which
tracks the leading 10% of sustainable companies in terms of economic, environmental and social

criteria. It is part of the communications Environmental Excellence Initiative; a North American
group focusing on promoting sustainable environmental practices within the telecommunications
industry. Clearly, Telus is a company that is aware of its environmental responsibilities and the
economic advantages to building and operating sustainable practices.
In the reconstruction of their downtown Vancouver head office, the William Farrell
Building was completed by Busby Architects and Associates, Keen Engineering as well as strong
participation by Telus' own architectural department. Telus decided that they would keep the build-
ing's original infrastructure, however modernize its appearance to reflect the company's vitality
and positively contribute to the urban streetscape. The modernization while revitalizing the inte-
rior, also provides a safe, efficient, healthy, productive workplace for its employees and customers
alike. The building was to be recycled and reused, rather than rebuilt, believing that restorations
could create sustainable modern environments, rather than waste energy and material involved
in the destruction of the old building. The structure of the existing building was preserved and left
essentially unchanged, and a new skin of double-glazed, fritted and frame-less glass was sus-
pended off of the existing structure. This groundbreaking system made the William Farrell build-
ing the first triple-skinned building in Canada.
Generally, double skinned buildings consist of two layers of glass cladding, creating an
airspace separation between the two layers ranging between 10" and 30". This airspace, or
plenum, acts as insulation for the building deterring extremes in temperature, wind and sound.
(Land and Herzog). Sun shading devices are commonly located between the two skins, reducing

the heat gain in the building. Double Skin façades may fall into one of four types: The Buffer
Façade, The Extract Air Façade, The Twin-Face Façade and the Hybrid Façade.
The building employs the Twin Face Façade as its Double Skin. The Twin Face Façade
involves either a curtain wall or mass wall system with an outer skin of single glazing. For this
building, a double glazed outer skin envelopes the existing masonry wall along the South and
West facades. The entire system is considered to be a triple glazed system due to the double
glazed windows on the exterior and the single glazed windows on the existing structure. This
makes it Canada's first triple glazed building. The new glazed skin is suspended 900mm above
the existing building structure, and runs from the second story up the full height of the building,
creating a plenum. The width of the plenum allows for human access between the two skins for
both maintenance and cleaning purposes. In the winter, the interstitial space acts to insulate the
building, while in the summer the plenum allows for the heat to escape through the vents at the
top of the curtain wall. As the hot air rises the cool air falls naturally creating a pressurized air
space. This phenomenon is due to the Stack Effect, where the constant upward movement of air
lowers the temperature of the existing building's perimeter wall, cooling the interior environment.
Operable windows located on both the new exterior skin and on the existing building's masonry
façade allow for natural ventilation to enter and cool the workplace. During the summer months,
both sets of windows are opened at night to exhaust the entire building, while taking advantage
of night cooling. An under-floor
plenum is connected to the glazed
wall plenum through a flexible duct
connected to a forced air filter which
pumps the air through the work-
spaces providing the main distribu-
tion of ventilation to the interior envi-
ronment. Each workstation has a
control damper, an "in-floor diffuser"
connected to the under floor plenum,
allowing the individual to regulate the

airflow within their interior work environment.
The existing windows are double hung and
are easy for employees to operate. The exte-
rior skin has windows that may be operated
utilizing an electronic control from within the
office. The plenum, as a result, becomes a
temperature regulating façade. Motorized dampers at the top and bottom of the glazed curtain
wall are monitored by electronic thermostat sensors, situated at varying points along the mason-
ry of the building surface within the interstitial air space. They control the entire ventilation system
of the William Farrell Building. The dampers automatically open to vent warm air out at roof level,
and take in new fresh air from below when the air temperature in the plenum reaches 17.3
degrees Celsius. During peak daily traffic hours, only the top dampers will open to reduce the
amount of pollution entering the building. As the building is located in urban Vancouver, the bot-
tom dampers remain closed, eliminating much of the emissions of nearby vehicles. This attention
to site and detail creates a healthier work environment for all of its employees. Photovoltaic cells
are integrated into the glass banding along the top of spandrel the new glazed skin, which pow-
ering the motorized dampers.
To reduce heat gain from sunlight,
ceramic fritted glass was applied to the exteri-
or skin and acts as a solar shade. The por-
tions of fritted glass are strategically located to
block out the steep sun rays and to control
heat gain in the summer, all the while allowing
for lower rays to provide maximum light pene-
tration into the building and thermal radiation
in the winter. The ceramic fritting on the glass
has a horizontal pattern that varies in density
depending on orientation. Originally the archi-
tect's intention was to frit the entire façade.

This would have created an obstructed view of the city, therefore only a portion of the curtain wall
was fritted. The fritting also prevents glare while allowing sunlight to penetrate the building.
Natural sunlight is maximized through the daylight bounce created by light shelves. These are
applied to both the interior and exterior sides of the existing masonry wall and to the interior side
of the new glazing system along the South and West facades. These light shelves, made of
stretched white cloth, reflect low-level light into the interior spaces in the wintertime, and act as a
sunshade to steeper summer rays. Whitewashed concrete ceilings and walls help reflect the inte-
rior light evenly throughout the floor. With only half the intended ceramic frit applied to the build-
ings' façade, coupled with the light shelves and white walls, the interior environment of the William
Farrell Building proved to be very bright. These efforts worked so well that blinds had to be
installed after the renovation to further reduce workspace glare. The underlying concrete structure
was stripped of its plaster and terra cotta tile treatments, exposing it as much possible. This con-
crete is a good material for thermal heat gain and also acts to regulate the interior temperature of
the building. While the exposed concrete slab works efficiently as a thermal sink, it also creates
an acoustically resonant workspace. The work floors are currently being retrofitted with acoustic
paneling on the ceiling, negating the thermal sink. The exposed concrete created an environment

that was noisy and provided little privacy, a lot of time and effort were put in exposing the concrete;
it now has to be recovered to make this a useable space. Despite the post-renovation alterations,
the energy savings accumulated through the double skin façade, the use and deterrence of natu-
ral light provided by the fritted glass, the light shelves/shades, along with the thermal mass pro-
vided by the exposed concrete, are said to be "real and quantifiable" by Telus company analysts.
The new glazed skin allows the building to operate at an energy performance target of 55% of
ASHRAE 90.1. The energy consumption level for the building is about 35% more efficient than lev-
els stipulated by Vancouver's energy by-laws.
The Photovoltaic Systems are a clean and efficient approach to producing electricity.
Having little negative impact on the environment, photovoltaic cells are becoming a popular
method to gain energy in a sustainable and renewable way, these are being used in green build-
ing designs and as well as other consumer products.
First used in 1890, photovoltaic cells convert light energy into electrical energy, called the
Photoelectric Effect. Semiconductor materials absorb light energy that is directly transferred to
electrons in the material's atoms. Electrons move from the semiconductor material to an electric
circuit as a current. The current is created by two semi conductive materials, one having a nega-
tive charge, and one of a positive charge placed on top of each other. As electrons move from
the positive plate to the negative plate the flow of electrons acts like a battery. And from there the
current moves into the electrical circuit creating usable energy.
Three types of materials are frequently used as semiconductor material. They are: silicon, poly-
crystalline thin films, and single- crystalline thin film. The actual assembly of a cell consists of an
antireflection coating, allowing the most amount of light to be used, a top cell, tunnel diode which
is the route electrons take between cells, and a bottom cell and substrate which holds it together.
Two main types of photovoltaic systems used today are the flat plate system and con-
centrator system. Flat plate systems can be used on roofs or anywhere where thin panels are
optimal. Concentrator systems use plastic lenses and metal housings to amplify light energy
needed over a smaller area. These are generally more expansive to construct. In total, a com-
plete system includes PV modules or arrays, which are cells in varying combinations and sizes,
electrical connections, mounting hardware, power-conditioning equipment, and batteries to store
solar energy.

Each 1 to 2 inch cell produces 1 to 2 watts of power. Failure of photovoltaic systems are
quite low, yet if they occur it is usually due to cells cracking, short circuits, glass breakage and de-
lamination or electrical insulation breakdown. To combat this, multi-cell interconnections, series
and paralleling, and bypass diodes are being implemented.
The William Farrell Building most likely implements the flat style of Photovoltaic Cells. Since they
are set between the glass panels of the curtain wall it was necessary to use thin elements. This
required thin cells to remain flush with skin, rather than using bulky, thicker Photovoltaic cells. The
thin cells are generally less expensive and prove to be more cost-efficient to operate the fan and
dampers.
The William Farrell Building, was originally constructed in 1940, and serviced the cities'
telephone systems, housing analog communication equipment, administration and technical staff.
The original structure consisted of cast-in-place concrete with exterior brick cladding and punched
windows. The windows were single glazed wood sash, and were covered with adhesive reflective
solar film. The interior walls were treated with plaster and terra cotta tiles. The building cooling
loads were handled by a central chilled water system while heating was provided by a central
steam system to perimeter radiation units. Each space in the building was provided with an equip-
ment room containing room dedicated chillers and radiators. This layout proved to be an inefficient
use of space and energy. Waste heat from the adjacent telecommunication equipment buildings
produced by their large chillers is gathered and fed to into the Telus building to meet any heating
requirement the building may have. With the renovation, typical floors now have only one main air-
handling unit per floor maximizing space and energy efficiency.
When the building was gutted and stripped of its suspended ceilings to expose the con-
crete structure, high floor to ceiling heights were achieved. Because of this high floor to ceiling
height, a raised access flooring system was incorporated with an under floor air and wiring plenum.
The floor air plenum distributes fresh air to the spaces from the glazed air plenum. The fresh air in
the interior space warms due to human and machine activity, and rises to be exhausted through
vent back into the glazed air plenum where it can then be exhausted to the exterior. The operable
windows provide natural ventilation while an under floor air plenum supplies the occupied space
with a constant airflow. The optimum temperature for this building is 17.3 degrees Celsius. Two-
pipe fan coil units draw air from the pressurized air plenum to the workspaces and return air from

the stratified level to be exhausted through the louvers. The heating in this building is primarily
generated through heat recovery from a year-round process load.
The overall embodied energy of the building is low due to extensive use of recycled and
reused materials. While the exterior shell of the exiting building was maintained, the interior of the
space was gutted, and through this process, ultimately provided an overall increased air quality to
the interior spaces. The majority of the material removed from the building was recycled and
reused in the renovation or sold as recycled product to local industries. Any material removed from
the building that was not reused was either toxic (i.e.: contained asbestos) or proved to be of little
economic values to local industries, as in the case of the terra cotta tiles.
Any materials not either reused in the building or sold, were kept by the client and stored
in a warehouse for future use. As for the reused materials, the ground floor Andersite stone and
Granite was re-cut to fit new windows openings. Excess stone was salvaged and resold. The inte-
rior renovation occurred one floor at a time so that salvaged doors, door-frames, lighting fixtures,
mechanical equipment and furniture could be move to a completed floor while work was being
done on that floor. Existing handrails, stairs and windows were retained. Marble toilet partitions
were reused with the building along with the existing fluorescent light fixtures, which were relocat-
ed to the basement. Copper bus ducts were modified and reused as guardrails. Two existing air-
handling units were relocated and reused along with lift shafts, cabs, and operating machinery that
was modified where necessary and retained. Recycled materials contributed to 75% of total mate-
rial mass. From what they demolished, 30% of total waste by weight was salvaged. Because the
structure of the building was not demolished it therefore was considered re-usable material and in
conjunction with additional recycled materials, combine to total the recycled building materials as
75% of total building materials by mass.
The new curtain wall was designed so that it may efficiently be disassembled keeping the
framing and glazing intact. As well, many interior components such as the suspended lighting,
electrical conduits, sprinklers, raised access flooring and carpet tiles, floor mounted washroom fix-
tures, sinks, mirrors, steel studs, electrical equipment, concrete blocks, interior doors, frames and
washroom cubicles were left exposed so that they may be easily disassembled and reused.
Any new material used, and any adhesive components used in the renovation were chosen as
being non-toxic materials and compounds, to reduce green house gases and ensure healthy build-

ing standards. The new concrete used contained 25% recycled fly ash, a post-industrial product
and recycled steel reinforcing bar. Finishing materials used focused on low volatile organic com-
pounds emissions, such as low VOC paint, no VOC linoleum flooring, and water-based adhesives.
The carpets installed in the building were low pile, tight weave with low emission backing were
used and the maintenance cleaning supplies are also low volatile organic compound cleaning
agents. These healthy building materials improve the indoor air quality of the space contributing to
increased productivity and health among employees - which also increases the economic value of
the building in terms of real estate value ensuring a longer, flexible life span for the building. To
ensure that this building has a long life span, the original concrete structure was designed and
strengthened where necessary to carry machinery loads so it will be flexible for future occupancy.
By recycling the existing building and materials as much as possible, the renovation to the
William Farrell Building diverted over 16,000 tons of solid landfill waste. The triple glazed skin as
well as other environmental and energy efficient considerations employed in the redesign saved an
estimated 15,600 tons of greenhouse gas emissions (CO2) and in the future, the building is pro-
jected to save over 520 tons of greenhouses gas emissions a year. With this calculation, over a 75-
year life span, the building will save 54, 600 tons of greenhouse gas emissions.
Vehicular considerations:
A bus stop is located in front of the building. The building is located 100 meters from a
major bus station and 200 meters from the "sky train", a Light Rail Rapid Transit station. The "West
Coast Express" train and Sea Bus terminal is located four blocks away from the building. The com-
pany supports an active carpool program and a cycle park located adjacent to the building. There
are shower, changing rooms, and fitness facilities located in the basement of the building.
The original building was built to the property line thus there was not, and is still, no veg-
etation on the site, other than a few trees at the perimeter of the building. A green-planted roof
would help compensate for the building's footprint on the environment.
Feasibility:
As compared with traditional cladding systems in North America, double skin systems
may cost up to four or five times in price. This increase in price is due to additional engineering
costs, and increase in material (special glass) and labour costs due to unfamiliarity among the
trades, as well as generally higher maintenance costs. If the initial cost can significantly reduce the
Allison Boyes, Kerri Henderson, Andrea Krejcik and Bronwyn Sibbald - 3A Environmental Design
33
overall ongoing operating cost of the building than the initial capital investment can be justified.
Telus put forth an up-front financial commitment that will pay for itself over time. Their primary moti-
vation was a dedication to environmental sustainability and a healthy workplace. This is impact was
immediate: the first year helped reduce green house gasses significantly. Telus proves through their
environment policies and beliefs that they are a responsible company dedicated to the well being
of their employees and the environment. This building was successful in many ways, the environ-
ment and people benefited greatly from Telus' environmental goals. In the past, there had been
health-related complaints by some employees, which were perceived to be the result of "sick build-
ing syndrome". These employees have stated that as a result of this renovation they feel much bet-
ter and healthy in the updated William Farrell Building.
Overall, the environmental considerations for the building were received with great suc-
cess. Currently, the building is in the preliminary stages of adding a "green" atrium addition to the
north façade in order to incorporate more sustainable elements into the Vancouver Building.
