What is a Green Building?
Green Buildings integrate social
and environmental goals with
financial considerations in
real estate projects”
-Rocky Mountain Institute

What is a Green Building?
IAQ less energy
Light less materials
functionality less water

Ontario’s Building Code
Objective OR:
“to limit the probability that, as a result of the
design or construction of a building, a natural
resource will be exposed to an unacceptable risk
of depletion …”

Ontario’s Building Code
Objective OR:
“to limit the probability that, as a result of the
design or construction of a building, a natural
resource will be exposed to an unacceptable risk
of depletion or the capacity of the infrastructure
supporting the use of the resource will be exposed
to an unacceptable risk of being exceeded.”

Ontario’s Building Code
Appendix A, A-1.1.2 Limit of Application
“The provisions of this code are intended to
establish minimum acceptable standards for …
conservation [and] environmental integrity…”

Design and Construction
Traditionally in North America, design and
construction uses the philosophy “If brute force
doesn’t work, you’re not using enough of it”
-Bill McDonough
www.morrisonhershfield.com
Integrated Design
Series of design meetings at all stages of design
and construction
Begins very early in the design process
Owner, full design team, specialists, energy
simulator, cost consultant, users
Very inclusive and open
www.morrisonhershfield.com
15
Integrated Design
The team must work together, not against one another
Think outside the box
www.morrisonhershfield.com
Integrated Design
Conventional
Cost-effectiveness Limit
“Optimizing components in
isolation tends to
pessimize the whole system –
Diminishing
and hence the bottom line.”

School Studies
1999 American Study, 21,000 students:
– Progressed 20% faster in math and 26% better in
reading (daylit to poorly lit classrooms)
North Carolina School Study (3 schools):
– Average test score improvement of 5% in daylit rooms
1992 Alberta Study:
– Attended school 3.5 days more per year
– Quieter libraries
– 9x less dental decay and grew 2.1 cm more over 2 years
