    1. Preliminary Design Presentation Group 5 Arlington, VA • Kyle Desrosiers, Foundations Engineer • Mohamed Mandeel, Structural Engineer • Matthew Switzer, Fluid System Engineer • Peter Bowlin, Building Thermal Systems Engineer • Evan See, Solar Thermal Systems Engineer

    2. Agenda Foundations Analysis Roof Truss Analysis Fluid System Analysis Building Thermal Analysis Solar Thermal Analysis Conclusion/Questions

    3. Foundations Analysis Kyle Desrosiers

    4. Foundation Design • Type: Full basement, conditioned • Material: Concrete with steel reinforcements (if necessary), still evaluating • Dimensions: 50ft wide x 26ft long Rectangle • Max depth (relative to ground surface)= 7 ft • (at front of house) • Wall thickness= 10 in.

    5. Foundation Design • Footing: • Width= 16 inches • Location= 1 foot below frost line • Frost line= 10 inches • Radon Mitigation • Action Level: 4 pCi/L • Avg radon level for Arlington County=3.4 pCi/L • Methods: Spray, Air ventilation system, soil depressurization

    7. Roof Truss Analysis Mohamed Mandeel

    8. Truss Design • Truss Type: Room-in-attic truss • Beam Size: 2”x6” or 2”x4”, still calculating • Number needed: 26 trusses total for 50' of length, spacing of 2' between trusses. • Pro/E model • Calculations are done using Ansys

    9. Basic Room-in-Attic Truss Designed

    10. Fluids System Analysis Matthew Switzer

    11. Basic Storage & Pump Needs • Water Storage Needs • Approx. 1 gal per 1ft2 FPC • Estimated FPC area • 300-400 ft2 • Pump TBD by FPC needs • Most likely a centrifugal pump • Flow rate • Feet of head required

    12. Copper Long term durability Increased resale value Less bulky Corrosion Long Warranties Costly ~http://www.builderswebsource.com/techbriefs/cpvccopper.htm PVC Approved for almost all building codes Resists corrosion/abrasion Cost effective Easy installation 100 psi rated @ 180oF Self-insulating Diameter limitations (1.5”-2” max) “Plastic” water taste Easily Damaged Copper vs PVC

    13. Exchanger Types • Flow Types • Cross Flow • Counter Flow • Most Efficient • Parallel Flow • Multi-pass Exchangers • Combination of flows • Shell and Tube Exchangers • Separate “circuits” of water flow • Number of passes • Size depends on economics and maintenance needs • High pressure & high temperature

    14. Building Thermal Analysis Peter Bowlin

    15. Arlington, Virginia Monthly Weather Data Zip Code: 22201 This is data typical of a moderate to colder climate, so the required R-values of the insulation used will be fairly high.
