1. 2013 Solar Decathlon Team Kentuckiana Phoenix House University of Louisville Dr. James Graham Barton DeJarnatt – ECE Martin Dombi – ECE Karl Fleischmann - ECE

2. Project Purpose/Concept Provide quickly deployed emergency housing in the wake of a natural disaster. – Designed to be inhabited in 1-2 weeks. Allow families a return to normalcy following destruction of their primary housing. – Not feel like a trailer or temporary housing (“shack”) Be a “net-zero” grid-tied home – Following a disaster, a community of displaced families could contribute back with produced energy.

3. Concept Pictures of the House

4. Our Mission Implement, integrate and improve previously designed house electrical, lighting and networking systems. – PV power wiring, grid power wiring, electrical outlets, lighting, data drops and networking equipment. Produce “As-Built” drawings to include in the project manual and formal report submission to the Department of Energy (DoE) – Wiring schematics, elevations, schedules, detailed equipment specifications and supporting systems drawings

5. Project Necessity Power generation is shifting away from centralized facilities (power plants) The consumer market is demanding a greater efficiency with reduced environmental impact There will still be a need for centralized generation but the increase in development will slow down

6. Background This project was necessary for entry into the US DoE Solar Decathlon. The culmination of a project 2 years in the making. Joint venture between UofL, Ball State and UK. Electrical systems needed redesign as parts that were not specified in the initial planning phase were obtained. – Design had to be altered to accommodate donated materials The completion of this project will open up research opportunities for the University of Louisville.

11. Operational Concept If used properly, the user will not experience any interaction with the electrical system. – Meant to be a background system. – If the user has to directly interact with the system, something is not operating properly. User will notice significantly reduced utility bill. User can portal in and view generation and usage details.

12. Functional Requirements Fulfill the requirements of the Building Code SD 2013 document Section 6. Electrical – Governing Code: 2011 NEC – Drawing Requirements: Detailed drawings of receptacles, switches, light fixtures, etc. PV System details Provide a key for electrical symbols

13. Functional Requirements Fulfill the requirements of the Building Code SD 2013 document Section 6. Electrical – All receptacles must be tamper-resistant – Outdoor Receptacles must be Ground Fault Circuit Protection rated and weather proof. – Arc Fault Circuit Protection and Ground Fault Circuit Protection where needed as defined by the NEC – All Electrical Equipment must have an appropriate listing – PV system must follow NEC – Each team shall provide a grounding electrode conductor from the dwelling’s main service equipment to the organizer utility panel, however, there shall not be a grounding electrode.

17. Solar Decathlon Competition The winning team produces a house that: – Is affordable, attractive, and easy to live in – Maintains comfortable and healthy indoor environmental conditions – Supplies energy to household appliances for cooking, cleaning, and entertainment – Provides adequate hot water – Produces as much or more energy than it consumes.

18. Contest Categories Architecture Contest (juried) Market Appeal Contest (juried) Engineering Contest (juried) Communications Contest (juried) Affordability Contest (juried) Comfort Zone Contest (measured) Hot Water Contest (measured) Appliances Contest (measured) Home Entertainment Contest (measured and juried) Energy Balance Contest (measured).

19. Engineering Contest The hundred points for this contest are divided amongst: – Functionality – Efficiency – Innovation – Reliability – Documentation

20. Communications Contest Challenges teams to educate others about their houses, their experiences, and their projects. The Communications Jury evaluates: – Web content quality, appropriateness, and originality – Audiovisual presentation information, the accuracy of the representation of the as-built house on the competition site, accessible captioning, clarity of the narrative, and creativity – The quality of onsite graphics, photos, displays, and signage – The delivery of messages to target audiences and people of all abilities – The use of innovative methods to engage audiences

21. Hot Water Contest The U.S. Department of Energy Solar Decathlon 2013 Hot Water Contest assesses whether a house's water heating system can supply all the hot water needed for daily washing and bathing. Teams score points by successfully completing several 15-gallon "hot water draws." The goal of this task is to deliver 15 gallons (56.8 l) of hot water (110°F/43.3°C) in 10 minutes or less.

22. Appliances Contest This contest is designed to mimic the appliance use of an average U.S. home. Teams earn points for: – refrigerating and freezing food – washing and drying laundry – running the dishwasher

24. Energy Balance Contest Each team house will be equipped with a bidirectional utility meter that enables competition organizers to measure the net energy a house produces or consumes over the course of the competition. Full points are received for producing at least as much energy as its house needs during contest week (Net Zero)

25. Net Zero status achieved

26. Contest Results 1 st in Affordability 1 st in Energy Balance – Tied with all other teams Placed 15 th out of 19 teams

27. Project Status The Phoenix House has returned to the University of Louisville – Sitting in Limbo The Dean’s office is determining the next course of action with the house, possible suggestions have been: – Sell it – Use it for research – Use it as a showpiece for prospective engineering students

29. More Lessons Learned

30. Future Recommendations Use a smart meter system such that data acquisition is a simple process for the consumer Train students in all software packages used for documentation
