5. A Brief History of Green Building
1970’s increase in oil
prices
Need for greater energy
efficiency, renewables
1989 AIA formed a
committee to study
impact of buildings on
environment
1992 AIA release
“Environmental Resource
Guide” funded by EPA
1992 EPA & DOE create
Energy Star
1993 USGBC
1993 Greening of the
White House
1998 USGBC starts
LEED program

6. The Year is 1957…
Dwight Eisenhower is elected President for the 2nd
time
“Leave it to Beaver “ premiers on TV
Average price of a home is $20,000 - Average annual income $4,500
Price of gas $.24 – Loaf of bread $.19
Two professors from MIT design an affordable and highly flexible house
Partner with Monsanto and Disney to build their vision of what a home
might look like in 1985
The House of the Future, built of plastic, opens
in Disneyland…

8. Monsanto House of the Future
Open for 10 years – 20 million visitors
Torn down in 1967
Would not go down without a fight
Wrecking balls literally bounced off the glass-
fiber, reinforced polyester material
Torches, jackhammers, chain saws and shovels
did not work
Finally, choker cables were used to squeeze off
parts of the house bit by bit to be trucked away

9. During a 2014 presentation on the
House of the Future
MIT Museum Architecture Curator
Gary Van Zante stated,
“In the end, Monsanto found that the idea of living
in a plastic house was an idea
that the public would not accept.
The public did not like to be enclosed in plastic.”

15. Green Building &
Sustainability
Most quoted definition of sustainability:
“Development that meets the needs of the
present without compromising the ability of
future generations to meet their own needs."
Source: Our Common Future, 1987, Oxford University Press

16. EPA Definition of
Green Building
Green building is the practice of creating structures and using
processes that are environmentally responsible and resource-efficient
Takes into account building's life-cycle from siting to design,
construction, operation, maintenance, renovation and
deconstruction
Expands and complements the classical building design concerns of
economy, utility, durability, and comfort
Green building is also known as a sustainable or high performance building
Source: EPA

17. EPA Definition of
Sustainability
Sustainability is based on a simple principle
Everything that we need for our survival and well-being depends, either
directly or indirectly, on our natural environment
Sustainability creates and maintains the conditions under which humans and
nature can exist in productive harmony, that permit fulfilling the social,
economic and other requirements of present and future generations
Sustainability is important to making sure that we have and will
continue to have, the water, materials, and resources to protect�
human health and our environment

18. Sustainability Green Building
The differences

19. Definition of
Greenwashing
Disinformation disseminated by an
organization so as to present an
environmentally responsible public
image
It’s whitewashing,
but with a green brush

22. Why is this information important?
Rising energy costs
Heightened consumer awareness
Responsible building practices
Moral and economic imperative
Enhanced/emerging technologies are
less expensive and more readily
available
State and federal guidelines/initiatives

23. Green Growth…
National Association of Home Builders reports that
as of the first quarter of 2014, housing contributed
$2.47 trillion to gross domestic product
Since 2005, the green share of new single family
residential construction has grown dramatically—
increasing from 2% in 2005 to 23% in 2013. This
23% market share equates to a $36 billion market
opportunity

48. Where to Build?
Assessing and Comparing
Potential Building Sites
 Considerations – new house or renovate
 Community – relationship between a building
and the larger community
 Site choice – previously impacted
or “Greenfield site"

49. Previously Impacted – Consider building on a
degraded site

50. Mixed-use development is conducive to
bicycling and walking, so it can reduce
the use of automobiles

51. Evaluating “Greenfield Sites”
Site assessments should examine:
Topography
Vegetation
Precipitation
Solar energy
History of the land

52. Topography Ground Water
Site Assessments

53. Vegetation Wildlife Habitat

site’s uniqueness
Minimize distances from
utilities
Take advantage of natural
shading
Pre-plan septic systems

130. Creating A Safe Indoor
Environment
ELIMINATE BAD INDOOR
AIR QUALITY
 FIRST, eliminate material or
pollution source, if not
 SECOND, isolate from living
space
 THIRD – mechanically ventilate
(exchange internal air 2-3
times)

131. Healthy Indoor Environment
Strategies for avoiding moisture problems
Eliminate moisture sources
Install quiet bathroom fans
Install a kitchen range hood fan
Ensure proper flashing and roofing details
Provide roof overhangs

133. HEALTHY INDOOR ENVIRONMENT
Design to control radon
Design to eliminate
need for pesticide
treatment
Keep garage separate
from house
Design to minimize
exposure to EMF

134. Design to Control Radon
Designing and
building a house for
radon control
involves planning
ahead so that a
radon-mitigation
system may be
seamlessly installed
should it become
necessary.

135. Detached garage for better air quality
Attached garages must
be extremely well-sealed

136. Choosing Products And Materials
For the House
Avoid combustion appliances that are not
sealed-combustion
Minimize use of wall-to-wall carpeting
Avoid standard particleboard
Choose zero-VOC or low-VOC paints,
finishes, caulks, and adhesives
Seal products to trap harmful chemicals

138. Vented Ventless

142. Balanced Ventilation System
Incoming and
outgoing
airstreams
balance one
another
Heat in the
outgoing
airstream can
be captured
with an HRV or
ERV

145. Material & Products for Green Building
Select products that support your effort to create a
healthy environment for your home without
hurting the planet in the process

146. Green Products Criteria
Life cycle impacts
are low
Floor tile made of recycled
glass is green because it is
made from waste material
Fluorescent bulb is green
because it reduces energy
consumption
Products that
 Are made with salvaged,
recycled, or agricultural
waste products
 Conserve natural resources
 Avoid toxic or other
emissions
 Save energy or water
 Contribute to a safe, healthy
indoor environment
Green Building Materials

147. What is a
Life Cycle Assessment?

149. CONSTRUCTION WASTE
 Reduce job-site waste
 Buy building materials with minimal packaging
 Buy building materials made from recycled waste
ReuseReuse
ReduceReduce
RecycleRecycle

150. Re-using job-site waste
Renovation
 Re-use whatever you can
Recycling job-site waste
 Develop a waste management plan
 Separate waste for recycling
Proper disposal of non-recycled waste
 Don’t bury
 Don’t burn
 Bring to proper sites

151. RESPECTING and CONSERVING WATER
Home Water Conservation
Water-efficient plumbing
fixtures and appliances
Hot water distribution
Design landscape to
conserve water

152. Toilets, Showerheads, Faucets
1992 conservation act
mandated water
conserving plumbing
fixtures
1.6 gallons per flush,
many are less than 1.3
gallons
Saves 30,000 gallons
per year – over $100

153. Rainwater Harvesting
Rainwater & snowmelt are captured
Stored in a
cistern, filtered,
then used for a
variety of indoor
functions
Bathing
Toilets
Kitchen
Drinking
Garden

154. Wastewater
Septic systems can be better designed
Composting toilets – use biological
decomposition
Gray water recycling
Re-circulating sand filter – site than can’t
support a conventional septic system
Build an artificial constructed wetland

155. Gray water separation and treatment
Collect water from showers, bathroom,
sinks, washers for surface irrigation
A storage
tank can be
used to
accept gray
water
Water is then
released
slowly to
plants

156. Managing storm water
Impervious surfaces prevent water filtering into aquifer -
Goes to storm sewers instead
STORM WATER CONSERVATION METHODS
 Cluster homes
 Minimize impervious surfaces (driveways)
 Avoid directly connected impervious surfaces
 Harvest rooftop rainwater
 Use porous pavement materials
 Avoid curbs –allow flow to vegetation
 Avoid steep slopes
 Avoid unnecessary soil compaction

157. Green Building and The Landscape
Landscaping
with
Energy
Conservatio
n
In mind

158. Plan to Conserve
Plantings that require
little or no water and
are sited properly
Plantings that are
naturally resistant to
pests
Minimize turf
Naturalize areas
“Don’t
blow it
–
good
planets
are
hard to
find.”
-Quoted in
Time

159. Landscaping With A Purpose
Aesthetically pleasing
Provides Shade
Blocks wind – funnels breezes
Provides Food
Provides habitat for wildlife
Helps increase solar gain

160. Soil
amendments
