  4. Bill Cox Lisa Major Nick Henthorn David Koenig Keshav Prabhu Bill Cox Architecture / Web Team

  5. Bill Cox Web Team Objectives • Increase access to team deliverables • Provide one location for all resources • Gather feedback from Habitat staff and volunteers to maximize effectiveness of the Web Project http://epics.ecn.purdue.edu/hfh/web_project

  6. Bill Cox Go to Web • Habitat Home Efficiency, Selection and Construction Online Resource Enter Guide http://epics.ecn.purdue.edu/hfh/web_project

  7. Keshav Prabhu Architectural Team Objectives • Materials list program • POS and database program

  8. Keshav Prabhu Program Attributes • Capabilities • Many different styles of homes • Cost comparison between vendors • Limitations • Electrical, plumbing, and HVAC

  9. Keshav Prabhu Materials List Input

  10. Keshav Prabhu Materials List Output • Sections • Quantity buy • Quantity O/H (out of house) • Material description • Piece cost • Total cost

  11. Keshav Prabhu Edit Donor Information Edit Store Stock Resale Store Volunteer Ring Up Customer Inventory POS and Database • Purpose • Track inventory in the Habitat resale store • Track material donors • Provide user with point-of-sale terminal functionality • Status • Gathering requirements • Creating tables in database

  12. Keshav Prabhu Resale Store POS and Database • Resale store sells donated building materials not used by Habitat • Inventory tracking and cash register system is required • System must be intuitive so volunteers can be quickly trained

  13. Keshav Prabhu POS and Database Overview • Keep track of donated materials • Donor name • Item donated • Quantity • Cost estimation • PC used to run database and cash register applications • Cash register application will modify database and track sales • Handheld barcode reader • Label printer

  14. Donnie Austin Doug Crook Matt Selvey Brian Waller Rosann Magnifico Brent Phillips Doug Crook Energy Team

  15. Doug Crook Energy Team Objectives • Five basic analyses were performed to reduce energy costs: • Cellulose vs. Fiberglass • Caulking wall joints • Attic fan • Window film • Future cost

  16. Assumptions R-values Cellulose: 38-40 Fiberglass: 31 Costs Cellulose: $0.43 (labor + material) Fiberglass: $0.41 (material) Payback period Approximately 1.5 years Doug Crook Cellulose vs. Fiberglass

  17. Assumptions Reduces air infiltration by 15% Infiltration through walls accounts for 20% of total infiltration No reduction in R-value of insulation $30 to caulk a house Results Average Savings = $10.27 Doug Crook Caulking Wall Joints

  18. Assumptions Flat roof (no tilt), no solar absorption Ambient temperature Results Reduction of air conditioning energy costs = $14.50 Operating cost = $30 Modification not recommended Doug Crook Attic Fan Analysis

  19. U-Value = 0.45 Btu/hr-ft2-F U-Value dependent upon distance between window and film Simulated from Nov 1 to March 1 $8.97 per roll of film Average of $27 per home (3 rolls) Reoccurring cost each year Doug Crook Window Film Analysis Information provided by ASHRAE Handbooks, Manco Consumer Hotline 800-321-0253 and www.3M.com

  20. Doug Crook Future Cost Analysis: Natural gas price outlook: .2% cost decrease per year Electricity price outlook: .5% cost decrease per year Electricity consumption outlook: 1.1% increase per year Source of information: www.eia.doe.gov linked from www.energy.gov

  21. Doug Crook Future Cost Analysis: Typical Habitat for Humanity house showing total analysis (both electrical and natural gas combined) for current and future energy costs.

  22. Habitat for Humanity • Web Team • Home Selection guide • Home Construction guide • Home Efficiency Options • Architectural Team • Plans added to Floor Plan Selection Guide • Material lists program • Energy Team • Recommended Efficiency options: • Caulking Wall Joints • Cellulose Insulation

  23. Rosann Magnifico Future Plans • Web team • Upgrade deliverables • Feedback • Link to Habitat’s web site • Architectural team • Home plans • POS database • Energy team • Efficiency options • National involvement
