5 The Problem The quantity of energy we use is high, increasingly more expensive, and results in negative environmental impacts.

6 The amount of energy used in U.S. buildings is greater than that used in transportation or industrial sectors. US Primary Energy Consumption * Transportation, 28% Buildings, 40% Industry, 32% *DOE, EIA, 2007 Buildings Energy Data Book

7 There are over 124,000,000 households in the US. Much of the US housing was constructed before energy efficiency was a high priority. US Housing Years In Which Structures Were Built* 4% 8% 8% ** 5% 13% % % 13% % * As of 2005 ** Period through % <=1919

9 Case Study Levittown, PA Circa Construction

10 KC Environmental, Inc Evaluating Levittown Pennsylvania Homes for Energy Savings Part 1 A Case Study in evaluating the potential for energy conservation in existing tract housing developments.

11 Levittown PA ~17,300 SF Homes ~ 5,500 Acres Four Jurisdictions: Bristol Township Falls Township Middletown Township Tullytown Borough From the ASRO Collection

12 Features Six basic house models Slab-on grade construction Wood frame Oil-fired, hot water radiant floor heating Insulation R-11 to R-13 Single paned glass w/storm windows Note: Heating Oil Cost at Time Of Construction - $0.16/gallon.

13 Vintage of Homes Constructed in Levittown Municipalities 1% 8% 6% 1% 2% 8% 3% 3% 1% 3% 4% 14% % <= % 18% <= % Bristol Township Falls Township 3% 4% 1% 10% 10% 0%2% 8% 35% 13% 19% <=1939 2% 12% <= % 66% Middletown Township Tullytown Borough

14 A Few Numbers Levittown housing stock is probably valued at over $3.5 billion (assuming ranges of cost from $180,000 to $340,000 over the 17,311 homes that were built).

15 A Few More Numbers Levittown housing is estimated to: - consume 10,000,000 gallons of fuel oil per year and - use 155,000,000 kwh of electricity per year at a combined annual cost of $65,000,000.

16 A Few Numbers For the 50+ years of Levittown s existence: - 500,000,000 (500 million) gallons of #2 fuel have been used for home heating. - 7,750,000,000 (7.75 billion) kwh of electricity have been used.

17 A Few Numbers In environmental terms; for the 50+ years of Levittown s existence: 21,000,000,000 (21 billion) pounds of CO 2 have been emitted related to residential energy use.

18 We ve done heat loss estimates to evaluate the potential for savings to homeowners.

21 Results indicate a 43% reduction in heat load without modification to the heating system.

57 Cellulose Installation

58 Data From Homes

59 Project Plan Analyze Energy Usage From Utility Bills (100 houses) Perform Energy Audits/IR Scans Develop Solutions For The 6 Models Install Prototype Solutions Perform Post Installation Verification Training and Outreach Community Implementation

60 Current Needs We are actively requesting homeowners to submit utility bill information for this study. oil/electricity/gas

61 Current Needs Energy audits, at no cost to the home owner, will be performed for selected houses within the group of 100 homeowners that submit utility information subject to study funding. (~$500 - $750 value).

62 Current Needs Please look through your attics -we are still seeking copies of house plans for the Colonial, Jubilee, Pennsylvanian and Rancher house models.

63 A Note To Contractors And Homeowners Approval/Certification/Accreditation is required for providers under Energy Star, HUD, FHA, PA Home Energy, and KeystoneHelp programs for energy efficiency projects. Your project will not be eligible for low interest financing or rebates through these programs unless the work is performed by an approved provider.
