Overview of Sustainability and the Built Environment as it relates to Fossil Fuel Consumption and Climate Change
The basics of Green BuildingIntroduction to LEED, Green Points,
One Planet & other rating systems and criteria related to Green Building.
GREEN BUILDING. A holistic approach to design, construction, and demolition that minimizes the building’s impact on the environment, the occupants, and the community.

The United States comprises 5% of the total world population and
Americans use 25% of the world’s energy resources.
Buildings and the building industry consumes between 1/3 and ½ of the nations energy.

297 SF/person average floor area 1,000 SF 3.37 people per household
840 SF/person average floor area 2,200 SF 2.62 people per household
Construction of a 2,085 sq ft home uses up to 1.5 acres of forest
95% of old growth forests have been depleted
Generation and use of energy (electric, gas, oil, coal) are major contributors to air pollution and global climate change.
ENERGY USE
We spend 90% of our time indoors
Air inside the average home is 10 times more polluted than outside air on the smoggiest days
Million tons generated in a year in each county
21% from construction and demolition industry

SUSTAINABLE SITES
locally producedminimally-processeddurable and able to be maintainedhigh in recycled-content readily-recyclable
Flyash is a byproduct of coal burning power plantsUse of flyash in concrete diverts it from
landfills.The U.S. produces 1.3 billion tons of
Portland cement annually. This emits 1.3 billion tons of CO2 into the environment.
Concrete and rubble can be crushed and used for backfill and drainage purposes at the base of foundations
Using recycled instead of virgin materials saves money and natural recourses
FSC certification assures that the forest from which the wood is produced is managed in an environmentally and socially responsible manner.
Wood saving techniques:Framing walls 24” on center2-stud cornersLadder blocking at partitionsStacking trusses over studsUse single top plates
Builders’ Guide online at www.RECYCLENOW.ORG Hardware Lumber Plumbing Tile Windows Reclaimed wood
Reclaimed lumber can be used for non-structural applications
Reduces resource consumptionReduces landfill deposits
Plastic lumberContains only recycled
plastic resinsCheck manufacturer for
amount of expansion
Composite lumberMade with recycled
wood fiber and recycled plastic resins formed into deck boards
FIBER-CEMENT SIDING is composed of Cement, sand, and recycled cellulose
Minimize the amount of fresh water used within buildings and outside for landscaping.
Non Invasive SpeciesNo Species Require
ShearingDrought-tolerant Natives Minimal Turf AreasPlants Grouped by Water
Needs (Hydronizing)
•Mulch All Planting Beds•Soil Amended with Compost•Rainwater Harvesting•Greywater Systems
Install water conserving appliances
Install low flow aerators on faucets and showerheads
Insulate Water Heaters & Pipes
Hot water arrives at the fixture 5 times faster than on average
Locate Water Heater within 12 Feet of All Fixtures
Toilets Dual-Flush or maximum 1.28gpf
Showers use max 2.5 gpmFaucets use max 1.5 gpm
Improving energy efficiency and using renewable energy sources are effective ways to improve air quality and reduce the impacts of global warming
Passive solar buildings aim to maintain interior Thermal comfort.
Passive solar design does not include active systems..
Plant deciduous trees for shade
Natural ventilation is a key cooling strategy
Install window overhangs and awnings
Exceed the Title 24 Standard for your climate by at least 20%
Install expanding foam or caulk where wood connections are made or framing is drilled to
provide plumbing and electrical runs.
Low- E double-glazed windowsLow-conductivity framesLook for windows that have a
National Fenestration Rating Council (NFRC) label
Lighting controls include:DimmersSensors and timers
Install either at specific locations or as a whole house system
Can be adjusted to either draw warm air upward during the summer or push warm air downward during the winter
Best locations are bedrooms and living rooms
Exhaust excess heat and moisture from attic spaces by natural convection.Code requirement of 1 sq. ft. of net free area of
venting for every 150 sq. ft. of attic floor area – should be doubled.
Keep insulation from blocking soffit/eave vents
Cools a house without the use of air conditioningExhaust warm, indoor airBring in fresh, cool, outdoor air at nightFan mounted in a hallway ceiling on
the top floor
PHOTOVOLTAIC PANELS (PVs)
SOLAR HOT WATER
Attached garage is the single most significant contributor to poor indoor air quality (source: U.S. EPA)
Replaces vinyl flooringContains petroleum-
based products or chlorinated chemicals such as PVC which off gases VOCs
For slab-on-grade additions or basements
Great for radiant, in-floor heating systems
Durable and easy to clean
