4. 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 4

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

6.  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 6

7.  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 7

8.  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 8

10. 10  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. Project Activity:Week completed: Introduction to project, assign team rolesWeek 1 Visit church, talk to project partner, understand project Week 2 Introduction to energy modeling and 3D modeling software Weeks 3-4 Placing sensors in church and collecting data Weeks 5-6 11

12. 3D Modeling software  Team will use Google SketchUp Energy modeling software  Team will use TRNSYS 12

13. 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 13
