• Mini Green house or Biosphere
FEATURES OF BUILDING
A Mini-Biosphere
The centrepiece of the Engineering Student Centre will be
a beautiful glass-domed “green” garden atrium featuring
growing plants, running water and tranquil ponds. This
common area will not only provide a stimulating natural
environment conducive to student socialization and study,
but will also provide a unique educational opportunity.
Within this mini-biosphere, students will study and learn
how engineering design of the building itself impacts the
fragile natural environment. As students conduct water
management, biochemical, thermal energy, and other
studies, they will learn what it means to create efficient and
ecologically sustainable integrated engineering designs.
Designed by Students for Students
• Conceptual design phase of the three-year project will
begin in September 2004,
• Initial design work to be performed by students as part of
their 4th Year Design Project course. In 2005, supervised
students will conduct detailed integrated design work in
collaboration with industry- including architects and
engineering consulting firms- to tackle the structural,
environmental, materials, mechanical and electrical
requirements.
• The Centre is tentatively scheduled for completion in late
2006
Designed by Students for Students
Integrated Design Process
Core Team: architect, client, CE, SE, ME, EE, CE,
EnvE, BCE, IE plus a design facilitator
• Define performance goals at the outset
• Define sustainability goals using tools such as
GREEN GLOBES-Natural Resources Canada
• Emphasize and incorporate team work right from
the beginning
Designed by Students for Students
• ISSUES TO BE CONSIDERED
• Demolition of existing Bioengineering building
• Recycling of materials: scrap metals; ‘hot market’
$275/metric tonne. For example, China-not enough supply
• Structural, foundation, building envelope, energy,
materials, power supply, operational issues
• Type of construction: wood, smart concrete, precast/castin-place, steel?
Vision:Load reduction and increased efficiency: minimum
(zero, if possible) storm water runoff; reduced energy
consumption, use of green materials, mimimum ecological
footprint, use of renewable energy sources, eco-efficiency

the room is empty.
CCGT Green Roof –reduce stormwater input to city
sewer system
CCGT-Rain Harvesting
CCGT-Ground Source Heat Pump
CCGT-Design Features
• CCGT Design includes:
• ●
A ground source heat pump and pipes which carry fluid through a
series of lopped pipes 200 feet below ground level. The liquid is used
to regulate the temperature in the building.
• ●
Highly effective insulation, including the green roof, was
required to lower heating and cooling expenses.
• ●
CCGT uses natural gas to heat the building because it is a
renewable resource.
• ●
The building is made from manly local materials (this reduces
pollution related to transportation and helps the local economy).
• ●
Use less harmful chemical products both for the construction and
for the maintenance of the building.
• ●
The green roof creates oxygen from carbon dioxide through the
natural processes of the plant life.
York University Computer Science Building
York Computer Science Building
• The 9,282m2 computer science building, with 3
stories, was designed mainly for energy efficiency
but has many other ‘green’features.
Design Features
• energy efficient in the winter and summer
• heavy insulation and lot of natural light
• open concept design with a central atrium and
exhaust columns to allow natural venting and
natural lighting;
York Computer Science Building
• “thermal chimney effect”, : Warm air (daytime) rises up to
the ceiling and replaces cooler air. Warm air is siphoned
off using fans at the top of the exhaust columns and by
computerized windows at the top of the atrium. The hot
air is replaced by fresh air, which is collected at ground
level on the shaded north side of the building.
• -HVAC system turned off during many days of the spring
and fall days, when the external temperatures are relatively
moderate.
• This climate control has resulted in an energy consumption
rating that is 50% less than the ASHRAE requirements of
600 Mj/m2/yr, for a building of its size.
York -The lit oval area at the ceiling is one
of the exhaust columns that vents hot air
and lets natural light into the building.
York Comp Science Building
Additional Building Features:
• Green Roof: low maintenance natural vegetation;
irrigated with collected rainwater.
Used as
recreational area by faculty and students.
• Perimeter glazing on the windows; allows heat
control in warm temperatures. Manually operable
windows.
York Comp Science Building
Additional Building Features Cont’d:
● A large atrium space in the centre of the building brings light into the
centre of the building and houses tropical plants which flourish all
year.
● Acoustic sealing to minimize echoes and noise. (This is an issue for
an open concept design with an atrium or large lecture halls)
● To promote alternate transportation, covered bicycle racks and
shower rooms are provided.
● 50% fly ash concrete was used instead of standard concrete. York
has subsequently decided that all future construction on campus will be
done using 50% fly ash concrete.

York –Operational Problems
• Many unique mechanisms and features that
require maintenance and extra attention.
• The building’s temperature varies greatly
depending on what side of the building a reading
is taken. The south side is very warm and the
north side is very cold, because of the large
amounts of glass.
• The basement was reportedly “very musky” when
the building was first opened, however the
moisture levels have since been reduced.
LEED Accreditation
United States: the most prominent green building accreditation
program is called the Leadership in Energy & Environmental Design
(LEED) rating system. This is system for defining and rating green
buildings. A Canadian equivalent rating system (Canada 2000) is
being produced at this time. It is expected to focus on the same major
areas that the LEED rating system does.
These areas are:
● Sustainable Site Planning
● Safeguarding Water and Water Efficiency
● Energy Efficiency and Renewable Energy
● Conservation of Materials and Resources
● Indoor Environmental Quality
LEED Certification
•
The United States Green Building Council (USGBC) uses the LEED
checklist to rate a building. Depending on the total points achieved for
solutions related to the above areas, a rating for the building is awarded
as follows:
•
•
•
•
•
•
•
•
Certified
Silver
Gold
Platinum
26-32 points
33-38 points
39-51 points
52-60 points
Benefits
The benefits of receiving a rating from such an organization are more
positive publicity and it promotes a high quality of design. It also gives
designers a method of comparing new designs to old designs in order
to determine their success.
