EDSGN 100 Design Project #1, Team 3

1. EDSGN 100 Design Project #1, Team 3 • Christopher Cavanaugh, Ivana Matijevic, Nicholas Petrizzo, Andrew Channel

2. Exploring Our Community... • Neighborhood-wide Attributes • Home Attributes • Rationale

3. Project Goals • Comfort • Affordability • Environmentally Attractive • Tasteful Aesthetic Appeal

4. Neighborhood at a Glance • 30 Single-Family Homes • Approx. .5 acres per lot -- Drainage • Retention Pond, Produce Garden • Integrated waste treatment, irrigation, fertilizer system • Reclaimed/recycled asphalt (FHA-approved), two-lane roads

5. Neighborhood Plan Retention Pond Produce Garden

6. Excess Water Drainage • Spacing of Homes with .5-acre lots • Vegetation: Willows, Eastern Red Cedar Trees, etc. • Retention Pond • Irrigate Community Produce Garden • Source for ancillary home use (i.e. hoses, etc.)

7. Reusing Waste • Waste treatment plant adjacent to retention pond • Plant separates liquid, solid waste • Treated liquid ⇒ Other garden irrigation source • Treated solids used as fertilizer

8. Unique Produce Garden Model • Residents assessed small fee ⇒ Free Produce • Maintain garden/Pay for greenhouse • Small number of employees • Seeds

9. Garden Becomes Business • Produce garden open to public for sale • Turn Profit ⇒ Resident Fees Decline • Less financial burden for residents

10. Advantages of Garden • Full re-use of waste water and run-off • Fresh produce nearby • No fluctuating produce prices for residents • Average family consumes 360 servings fruit/veg. per month ⇒ one flat rate

11. Community Power • Electrical Power Sourcing: 2-fold • Geothermal Energy: powers HVAC (approx. 46% of typical electric bill) • Solar: powers rest of house (remaining 54% of typical electric bill) • System on grid: piece of mind, surplus sale to grid, fund maintenance

12. Typical Sustainable Home • Attractive to Middle Class Family of Four

13. House Specifications • Approx. 2,000 sq. ft. • 3 Bedrooms, 3 Bathrooms • 2 Stories

14. Ground Floor Layout Front Text

15. Second-Floor Layout Front

16. Sustainable Design Attributes • Energy-Star, environmentally friendly materials used wherever possible in homes • Design emphasis: large windows (especially West-facing) ⇒ less artificial light

17. Powering the Home • Average PA Home: 861 kWh/month • Projection: 800 kWh/month • Reason: Slightly smaller sq. footage, less need for artificial lighting

18. Roof Solar Units • Expectation: Solar power provides up to 60% of electricity if necessary • 240-watt panels (5ft. x 3ft.) ⇒ 25 panels per South-facing roof

19. Geothermal • Intent: Power every HVAC system (projected: 46% of monthly electric power) • Expectation: supply up to 50% of community power + surplus • Surplus resold to grid

20. Typical Home Furnace Size • Given: 2,000 sq. ft., R-19, R-30 and R-11 insulation; tight-fitting storm windows or double pane windows • Minimum Load: 58,000 btus • Maximum Load: 70,000 btus

21. Solar-Geothermal Duality Advantages • Solar power: greatest value per dollar • Projection: Break even approx. 3.5 yrs. • Geothermal: easily accessible, reliable • Materials for equipment: most eco-friendly

22. Compared To... • Wind Power: unappealing appearance, high maintaince • Hydroelectric Power: bad value for location

23. Home Water System • Connected to Public Water Supply • Average American Home: 400 gallons/day • Projection: 275-325 gallons/day • Rationale: Factors lessen water demand • Recycled water for outdoor uses • Low-flow technology for some appliances (i.e. toilets)

24. Cost-Benefit Analysis • Average Monthly PA Electric Bill: $97.75 • Sustainable Community Projection: $0 • Additional income to homeowner from surplus power sale to grid

25. Cost-Benefit Analysis • Water Usage: up to 31% savings • Affordable, predictable fruit/vegetable costs ⇒ savings on family groceries • Tax Breaks (varying) for eco-friendly aspects of each property: direct savings for homeowner

26. Summary • Tasteful, affordable homes with lower water bill, without electric bill, sustainable waste system • Feasible, economical, “green” electric power • Unique garden co-op model lowers grocery bills, attracts homebuyers • Potential tax breaks for buyer and builder
