Sustainable Strategies What we have learned
Sustainable Strategies • Reduce Reuse Reclaim and Recycle • Appropriate use of land • Use water and energy efficiently • Enhance human health • Strengthen local economies • Conserve plants and animals • Protect agricultural, cultural and archeological resources • Build and maintain economically • Nice to live/work in • Build it Beautiful
Life Cycle Costing VS LC Assessment • Life Cycle Costing – Cost at time of purchase is amortized over the life of the building. Example: A chair that costs $100.00 and lasts 50 years is better than a chair that costs $50.00 and lasts 10 years. Swedish Finish vs. Water Based floor finish • Life Cycle Assessment – “Cradle to Grave “ cost. How much environmental damage is done creating and transporting an What is the environmental impact during its life? What happens to it when is becomes unusable, is it recyclable?
Cradle to Grave – A one way street. Billions of dollars and huge quantities of natural resources are used to make things that are discarded in our landfills and incinerators. • We are called consumers but very little of what we purchase is actually consumed. Everything not for consumption is designed for you to throw away.
Construction Waste • 124 million tons of construction debris is buried in landfills every year. That is enough debris to build a wall about 30 feet high and 30 feet thick around the entire coast of the continental United States (4,993 miles). * • Each year the United States buries about 33 million tons of wood related construction and demolition debris in our landfills. As anaerobic microorganisms decompose this wood, it will release about 5 million tons of carbon equivalent in the form of methane gas.This is equivalent to the yearly emissions of 3,736,000 passenger cars. *
50 percent of consumed materials (globally) are used in construction and remodeling. ** • Re-using the lumber from just one house (2,000 square feet) saves 33 mature trees? * • For every ton of wood that is reused, we avoid creating 60 pounds of greenhouse gasses.* *Statistics are used with permission from the great folks at Deconstruction Institute **Statistics are used from Sierra Magazine - Jan/Feb 2005
How Can We Help? • Reuse, reclaim, reduce and recycle • Deconstruct rather than demolish Metro Recycling Toolkit Green Development Resource Center Deconstruction Services The Rebuilding Center Habitat For Humanity Restore
Appropriate use of land • Pringle Creek • Greyfield – Lands pre-developed i.e. Abandoned shopping centers • Brownfield – Land with contaminated soil • Urban Growth Boundary • Density
Use water and energy efficiently Water Efficiency • 8% of the electrical energy produced in this country goes into the production of potable water (16% in Calif.) • Strategies • Xeriscaping • Water saving appliances and fixtures • Reusing Greywater • Storm water collection for watering plants and flushing toilets
Use water and energy efficiently Energy Efficiency • Third Party Evaluators – LEED, Earth Advantage, Living Building Challenge • Advanced Framing Strategies • Better insulation • The importance of sealing the building envelope • Radiation Conduction and Convection • Mean Radiant Temperature • Low E windows • Roof overhang strategies • Heat Exchangers • Solar - Passive & Active (hot water photovoltaic) • Wind generated energy
Permeable material to prevent wind washing Wind baffle Blocking Knee Wall Solution
Insulation Types • Batts • Blown-in blanket • Spider • Spray foam • Hybrid • Rigid exterior
Staggered Studs • 2 Rows: 2x4 16” OC offset • Blown-in blanket • Better total wall R-value • No thermal bridging
Some Alternative Wall Systems • SIPS – Structural Insulated Panels • ICF – Insulated Concrete Forms • Composite blocks systems
Enhance human health Improving building ecology Strategies • Operable windows, adequate ventilation • Elimination of products that contain VOC’s • Adequate daylighting • Sick Building Syndrome
Strengthen local economies • Buy building products made locally • Mixed use housing promotes new businesses • Green culture supports local businesses by making a community more desirable to live in • Green culture promotes new businesses that support the green building movement. Solar industries as an example • Ecoroofs Everywhere • Ecohaus • Bureau of Planning and Sustainability • Yolo Paints • Zena Forest Products
Conserve plants and animals • Strategies • FSC lumber – Zena • Eco-roofs • Sustainable site development • Developing grey and brownfields to support habitat • Building within the urban growth boundary • Xeriscaping
Protect agricultural, cultural and archeological resources • Responsible Development • Eco Trust
Build and maintain economically • Think in terms of durability when choosing materials • Incorporate more passive systems to eliminate the need for maintenance • Smaller HVAC Systems • Operable windows/skylights • Low-E Glass • Smaller HVAC systems • Light shelves and eves • Better insulation • Advanced framing • Durable Materials
Nice to live/work in Pringle Creek • Mixed use • Shopping, schools, within walking distance • Community centered activities • Close to bus line • Trees and nature Eco Trust • Raised platforms for offices in the center of the room • Operable windows • Close to mass transportation • Support bicycle rising • Beautiful • Common gathering areas • Organic food

It was early recognized that green roofs could improve a building’sdurability, regulation of temperature, and overall aesthetic value. Residential building in Germany Photo: Greenroofs.com
The use of green roofs has increased significantly throughout Scandinavia. Ford dealership in Sweden Photo: Greenroofs.com
