2  Team Members  Project Partner introduction  Stakeholder information  HVAC/ERV introduction  Overall Problem  Design Process  Progress  Issues  Goals  Questions 2

3  Samir Solaiman  Project Leader  First Year Engineering, Freshman  Kevin Choi  Project Partner Liaison  Electrical Engineering, Sophomore  Nicholas Horein  Financial Officer  Interdisciplinary Engineering (Nanotechnology), Senior 3

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

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

14 14

15  Study construction plans of church  Split up church into eight arbitrary zones  Chapel  Multipurpose room  Five zones of classrooms  Roof/attic area 15

17 17

18 18

19  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 19

20 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

21  Budget (lack of sensors)  Lack of knowledge on subject  HVAC/ERV system  Problem itself 21

22 Project Activity:Week completed (Tentative): 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 the church and collecting data Weeks 5-6 Analyze dataWeeks 6-10 Transferring data to TRNSYSWeeks 9-14 Create alternative energy modelWeeks 9-14 Develop solutionWeeks

23 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, CO 2 -control, demand- controlled features 23
