Exploring Our Community...

•Neighborhood-wide Attributes

•Home Attributes

•Rationale

Project Goals

•Comfort

•Affordability

•Environmentally Attractive

•Tasteful Aesthetic Appeal

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

Neighborhood Plan

Retention Pond

Produce Garden

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.)

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

Unique Produce Garden Model

•Residents assessed small fee ⇒ Free Produce

•Maintain garden/Pay for greenhouse

•Small number of employees

•Seeds

Garden Becomes Business

•Produce garden open to public for sale

•Turn Profit ⇒ Resident Fees Decline

•Less financial burden for residents

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

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

Typical Sustainable

HomeAttractive to Middle Class

Family of Four

House Specifications

•Approx. 2,000 sq. ft.

•3 Bedrooms, 3 Bathrooms

Sustainable Design Attributes

•Energy-Star, environmentally friendly materials used wherever possible in homes

•Design emphasis: large windows (especially West-facing) ⇒ less artificial light

Powering the Home

•Average PA Home: 861 kWh/month

•Projection: 800 kWh/month

•Reason: Slightly smaller sq. footage, less need for artificial lighting

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

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

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

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

Compared To...

•Wind Power: unappealing appearance, high maintaince

•Hydroelectric Power: bad value for location

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)

Cost-Benefit Analysis

•Average Monthly PA Electric Bill: $97.75

•Sustainable Community Projection: $0

•Additional income to homeowner from surplus power sale to grid

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

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
