  8. Guidelines Competition Rules Compromise between Engineering and Architecture Energy Efficiency System Compatibility Market cost Supply Cost Biggest factor in product selection Product Selection

  9. Energy Consumption

  10. 43 Bosch Solar Module 255 Wp (Monocrystalline) Solar…Sun Energy Branches • SolarMount Evolution (UNIRAC) • Compatibile with Canopy House Modular Design

  11. Sunny Boy 8000 and 3000 inverters • TigoEnergy Module Maximizer • Gateway and Management Unit • Web-based module level monitoring Solar…Sun Energy

  12. Solar…Sun Energy • 36.5161 kW per day

  13. SunDrum • Increases efficiency of solar panels by 7% • Estimated 463 MJ of thermal energy produced per day Solar…Sun Energy

  14. SunDrum V V PCM Storage Tank Radiant Flooring E Hot Water Outlet V Hot Water Heater Cold Water Inlet Solar…Sun Energy Integrated Solar Thermal System

  15. Mitsubishi products: Wall-Mounted & Cassette style units • Multi-Zone Capability • i-See Sensor & Directional Vanes • Redlink control • Directional Air Flow HVAC Selection

  16. HVAC Mini-Split Components Supply & Return Max Cooling Capacity: 29400 Btu/h Max Heating Capacity: 34800 Btu/h - Units were initially selected based on estimated load requirements

  17. Home HVAC Loads

  18. Heat Collection

  19. Selected Vitocell–B dual heat exchanger as auxiliary storage tank • System is comprised of a 30/70 ratio of water to phase change material • To meet target temperature (120°F), Puretemp 48 was chosen as PCM Thermal Capacity http://www.jwderyan.com/images/vies-vcc.jpg http://viessmann.kotelki.ru/users/images/viessmann/vitocell/vitocell_100_b.jpg

  20. Thermal Capacity

  21. Radiant Flooring • Utilizes the excess heat stored in the water holding tank • Multiple zones are supplemented by secondary heat source • Decreases the heating loads that may be placed on the mini-splits. Radiant Flooring Hot Water Radiant Floor Heat

  22. Radiant Flooring Heat Transfer Rate: Q = m*Cp*T

  23. Pump Selection

  24. MQ Pump (Grundfos, Olathe, KS)

  25. All Solar Decathlon houses are required to have a wet sprinkler system to comply with: 2013 Solar Decathlon Building Code 2012 International Residential Code 2013 National Fire Protection Association System is separate & independent from potable supply water system Dedicated supply tank Dedicated pump for pressurization Dedicated piping system Fire Suppression

  26. Sprinkler Head Selection Tyco Rapid Response LFII Flush Residential Sprinkler Head ½” 20 x 20 Q = 22gpm P = 27.4psi Fire Suppression Selection Criteria Temperature Rating Coverage Area Coverage Density Pressure Demands Calculations (D) Density D = 0.1(gpm/ft2) (QEND) End Head Flow Rate (K) Coefficient of Discharge K = 4.2 (PEND) Pressure at End Head P = (Q/K)2 QEND = 21.6gpm PEND = 27.43psi
