1. Defining Sustainable Practices Dorothy Gerring Associate Professor Architecture Pennsylvania College of Technology “It is not necessary to change. Survival is not mandatory.” -W. Edwards Deming

2. Sustainability: The ability to meet our needs while preserving the ability of future generations to meet their needs.

3. Where we live. Earth from space: satellite DIRECTV 8 5:30pm EST November 13, 2006 Earth and Moon Viewer The Living Earth®, NASA Johnson Space Center The image above shows how our galaxy might look if viewed from one of our nearest- neighbour galaxies. The approximate location of our solar system within the galaxy is also shown. Of course, this isn't an actual picture of our galaxy, it is an image taken by the Anglo Australian Telescope of NGC2997, a nearby galaxy with a similar structure to our own.

4. What is your ecological footprint? http://ecofoot.org/ http://ecofoot.org/ Food Footprint 1.How often do you eat animal based products? (beef, pork, chicken, fish, eggs, dairy products) 2.How much of the food that you eat is processed, packaged and imported? Goods Footprint 3.Compared to people in your neighborhood, how much waste do you generate? Shelter Footprint 4.How many people live in your household? 5.What is the size of your home? 6.Which housing type best describes your home? 7.Do you have electricity in your home? Mobility Footprint 8.On average, how far do you travel on public transportation each week (bus, train, subway or ferry)? 9.On average, how far do you go by motorbike each week (as a driver or passenger)? 10.On average, how far do you go by car each week (as a driver or passenger)? 11.Do you bicycle, walk, or use animal power to get around? 12.Approximately how many hours do you spend flying each year? 13.How many liters per 100 kilometers does your car consume? 14.How often do you drive in a car with someone else, rather than alone?

7. Change is hard! People adopt new technology when the level of crisis is greater than the perceived pain of adopting the technology 5 steps: Denial, Anger, Bargaining, Depression, Acceptance New technology takes about 30 years to be integrated into society Pip Coburn: The Change Function 2006

Achieving high performance buildings 1.Design Planning and Innovation (low tech) Project Team: includes everyone from start Goal Setting: must have benchmarks Integrated Design: building envelope (insulative value), passive solar, daylighting, natural ventilation, landscaping, material selection (http://architecture2030.org/regional_solutions/insulation.html)http://architecture2030.org/regional_solutions/insulation.html 2.Adding Technology (high tech) Active solar (photovoltaics, solar water heating), wind, geothermal, biomass & biofuels, hydroelectric

14. Test What is the LEED System? LEADERSHIP in ENERGY and ENVIRONMENTAL DESIGN A leading-edge system for certifying DESIGN, CONSTRUCTION, & OPERATIONS of the greenest buildings in the world Scores are tallied for different aspects of efficiency and design in appropriate categories. For instance, LEED assesses in detail: 1. Site Planning 2. Water Management 3. Energy Management 4. Material Use 5. Indoor Environmental Air Quality 6. Innovation & Design Process

15. Test Levels of NAHB Ratings White Green Buildings worldwide are certified with a voluntary, consensus-based rating system. USGBC has four levels of LEED.

17. 2030 Challenge: architecture2030.org architecture2030.org All new buildings, developments and major renovations shall be designed to meet a fossil fuel, GHG-emitting (greenhouse gas), energy consumption performance standard of 50% of the regional (or country) average for that building type (targets).targets At a minimum, an equal amount of existing building area shall be renovated annually to meet a fossil fuel, GHG-emitting, energy consumption performance standard of 50% of the regional (or country) average for that building type. The fossil fuel reduction standard for all new buildings shall be increased to: –60% in 2010 70% in 2015 80% in 2020 90% in 2025 Carbon-neutral in 2030 (using no fossil fuel GHG emitting energy to operate). These targets may be accomplished by implementing innovative sustainable design strategies, generating on-site renewable power and/or purchasing (20% maximum) renewable energy and/or certified renewable energy credits.
