• 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

Chicago Centre for Green Technologies
Chicago CCGT- Solar Panels
                       CCGT
• Purpose: to reduce fossil fuel emissions released when
  electricity is produced.
• CCGT Design includes:
• ● Photovoltaic cells.
• ● Passive light designs including a green house with
  heat absorbing tiles and skylights.
• ● Smart lighting, which adjusts the electrical lights
  according to the available natural light, thus lowering
  electricity requirements.
• ● Motion-sensitive lights that turn themselves off when
  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 BuildingFeatures 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.

         Atrium
   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      26-32 points
•   Silver         33-38 points
•   Gold           39-51 points
•   Platinum       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.
