  4. ROOF TRUSS CONSIDERATIONS • Information Used In Analysis • Roof Structure • Standard Roof Sizes • Tiles • Factor of Safety Used • No attic necessary • Solar Panels • Most efficient between 30-40° • Each weighs around 80 lbs • Could have up to 4 solar panels • Each solar panel has a surface area of 4ft x 6ft • Environment • .2” of snow fall is the maximum ever recorded • Winds could reach up to 206 mph (F3 tornado) • Montgomery County has had 15 tornadoes since 1956

  5. ROOF TRUSS LIMITS • Beam Forces • Maximum bending stress of material is 1650 lbs/ft² • Maximum compressive stress is 1700 lbs/ft² • Forces on trusses • Flat Plate Collectors • F=3.33lbs/ft² • Forces in the negative y-direction • Plywood • F=2.15625 lbs/ft² • Force in the negative y-direction • Shingles • F=.304 lbs/ft² • Force in the negative y-direction • Wind F=.00256V² • F=102.4 lbs/ft² • Force in the x-direction

  6. ROOF TRUSS DATA COLLECTION • Factor of Safety (FOS) turns out to be 4.7 • Beam Loading(2”x12”) • Compressive loading failure is 24225 lbs • Bending moment failure is 313680 lbs-inches • Worst Case Scenario Calculations • Compressive load is 546.465 lbs • Bending moment is 66667 lbs-inches

  7. WALL CROSS-SECTION

  8. WALL INSULATION

  9. ATTIC INSULATION

  10. WINDOWS AND DOORS • Windows - Use lowE2 glass - U value of .36 • Doors • Patio Doors - use lowE2 glass - U-value of .35 • Front Door - insulated metal with a wood print - U-value of .26

  11. SOLAR WATER HEATING SYSTEMS • Hydronic System Analysis • Closed loop – Active system • Potable water routed to storage tank • Working Fluid circulates through collectors • Potable water is heated through heat exchanger • System requires auxiliary components like expansion tank, valves, etc.

  12. BASIC ILLUSTRATION

  13. MAJOR COMPONENTS ANALYZED • analysis & selection of suitable pump • selection of appropriate heat exchanger • selection of main water storage tank. • primary plumbing components – pipes For Each: • options, benefits and costs analyzed

  14. HYDRONIC SYSTEM PUMP ANLAYSIS • How the analysis was carried out : • Design analysis was based on Architectural & Solar Thermal systems & options were considered • Architectural: basement & overall house dimensions • Solar Thermal: two possible options of Flat Plate Collectors with varying flow rates, dimensions and pressure losses. • Result of Total System Head Loss :

  15. OPTIONS FOR MAIN PUMP • Grundfos UP Series Circulator • Stainless steel protects against corrosion • 3 Speed Super-Brute technology • Integrated removable check valve • Highest starting torque in its class • Quick connecting terminals • 3 yr warranty • Cost: $200-$400

  16. PUMP PERFORMANCE CURVE CLOSED SYSTEMS-UP SERIES

  17. BELL & GOSSETT WET ROTOR CIRCULATORS • Heat resistant, polypropylene impeller with closed design improves operating efficiency • Dura Glide Bearing System incorporates several components working together to eliminate seasonal freeze-up • Face plate and rotor sleeve feature corrosion resistant stainless steel • Cost : $100 - $300

  18. PUMP PERFORMANCE CURVEWET ROTOR CIRCULATOR – NRF SERIES

  19. HEAT EXCHANGER GEA FP HYDRONIC SERIES • Grazed Flat Plate • 3”X 8”, 14 plates, 8 GPM @ 5 Psi PD • Higher heat transfer co-efficient • High pressure ratings • Smaller size & weight • Cost: $200

  20. STORAGE TANK W/INTEGRATED HXSOLARIDE HE SERIES • Heat exchanger: copper tubing wrapped & secured to the tank. • Double wall, vented design for leak detection • Anode rod equalizes aggressive water action for prolonged tank life • Temperature and pressure relief valve included • Max Pressure 150 Psi • Pressure Drop thru coil @ 2Gpm is 4.8 ft • Cost : $1700, 6 yr Limited Warranty

  21. PLUMBING PIPES • PVC • Resistant to corrosion & abrasion • Lightweight, high impact strength • No water hammer • Easy, cost-effective installation compared to copper • Relative price stability over time • Cost: 3/4 In. x 10 Ft. PVC @ $2 • COPPER • Impermeable to contaminants & Biostatic • Will not burn or give off toxic fumes when exposed to fire • Withstand rapid temperature & pressure changes • Can leach lead/copper into water supply • Cost :Cerro 3/4 “ x 10 Ft. @ $18

  22. Flat Plate Solar Collector – Sunmaxx M2 Thermal f-value Output

  23. Flat Plate Solar Collector – Sunmaxx M2 21.53 ft2 aperture area 0.35 gpm flow rate Lower cost Smaller surface area and slower flow rate produce less hot water than SH Would handle 39.4% of hot water needs

  24. Flat Plate Solar Collector – Enerworks SH10US Thermal f-value Output

  25. Flat Plate Solar Collector – Enerworks SH10US 28.97 ft2 aperture area 0.52 gpm flow rate Higher cost Higher flow rate and larger surface area produce more hot water than M2 Would handle 47% of hot water needs
