  1. Neighborhood Sustainability Church Team

  2. Agenda • Team Members • Project Partner introduction • Stakeholder information • HVAC/ERV introduction • Overall Problem • Design Process • Progress • Issues • Goals • Questions

  3. Team Members • SamirSolaiman • Project Leader • First Year Engineering, Freshman • Kevin Choi • Project Partner Liaison • Electrical Engineering, Sophomore • Nicholas Horein • Financial Officer • Interdisciplinary Engineering (Nanotechnology), Senior

  4. Project Partner Latter Day Saints of Lafayette • Up to 250/300 attendees • Highest number of people on Sunday morning and Wednesday night • Stakeholders: • Churchgoers • Staff • Various other activities

  5. Project Partner • Overall goal: Improve Heat Ventilation and Air Conditioning (HVAC) and Energy Recovery Ventilation (ERV) system • Goal for this semester: Develop energy model • 6 units

  6. Heat Ventilation and Air Conditioning (HVAC) • Boiling point depends on temperature and pressure:Low pressure induces boiling, high pressure induces condensation • Comparison to aerosol can: When nozzle is pushed, pressure is released thus liquid is turned into gas. • Basic process: Evaporating cooler water into cool air, then “condensating” used air into warmer water

  7. Energy Recovery Ventilation (ERV) • Passes outgoing warm air from inside the house through a heat exchanger • In heat exchanger, heat from outgoing air is transferred (heat recovery) to cool incoming air • Ultimately reduced energy consumption and heating/cooling bills • ERVs naturally bring humidity up higher

  8. Project Partner: Problems • Unit made for use in Colorado, not suited for Indiana weather • Many wooden structures so humidity affects almost everything • Up to 87% humidity • Danger of mold growing if problem not addressed quickly • Constrained by physical seasons

  9. Design Process (box on Project Identification)

  10. Developing Plan for Semester • Develop energy model • Not constrained by seasons; can roughly test anytime • Software is needed • Energy modeling • 3D modeling • Collecting data is needed • Temperature and Relative Humidity (RH) sensors

  11. Progress

  12. Progress: Software 3D Modeling software • Team will use Google SketchUp Energy modeling software • Team will use TRNSYS

  13. Progress: Temperature/RH Sensors Temperature/Relative Humidity sensors • Placed in church on 10/3/2014 • Hobo MX1101 • Collects data, uploads it to iOS app server. Can also be seen via Bluetooth. • 4 units at disposal

  14. Progress: Temperature/RH Sensors

  15. Progress: Observe Behavior in Church • Study construction plans of church • Split up church into eight arbitrary zones • Chapel • Multipurpose room • Five zones of classrooms • Roof/attic area

  16. Progress: Observe Behavior in Church

  17. Progress: Observe Behavior in Church

  18. Progress: Observe Behavior in Church

  19. Progress: Observe Behavior in Church • Arbitrary zones to observe anomalies and behaviors • Things to consider in future: • Effect of windows and doors on sun radiation • Direction where sun travels over the building

  20. Progress

  21. Issues • Budget (lack of sensors) • Lack of knowledge on subject • HVAC/ERV system • Problem itself

  22. Goals

  23. Goals Goals for this Semester • Understand problem more: • HVAC/ERV system; investigate where exhaust air and other air travels around building • Church construction plans • Develop energy model and church rendering Goals for Future Semesters • From energy model, start developing solution. • Possible Solutions: • Implement humidity-control, CO2-control, demand-controlled features

  24. Questions?
