Putting it all together:
Energy is a 3 legged stool:
1. Harvesting: solar (PV and solar thermal), wind, geothermal, tidal, hydro
2. Storage: Hydrogen fuel cells, Concentrated solar thermal (CST), batteries, pumped storage hydro (PSH)
3. Conservation: energy efficiency, insulation (house and hot water heater), buildings, transportation
Smart grid ties all three of these together.
Metaphor- think of food: harvest the food, store the food, don't waste the food.
What is a smart grid?
1. resource aware
2. demand aware
3. time aware
4. storage capacity
5. load balancing/shedding
Energy audit (sources, loads, times, fingerprints)
Environmental audit (sound, air, lighting, etc.)
Social aspects (penalty or reward?)
Old testament approach: bad guys and good guys-not very effective, alienates those who can make change happen
Better: graduated approach
HPA Energy Audit:
Go to elab2.hpa.edu (credentials in class)
Look under telemetry for "HPA Energy"
Main buildings: IT, GPAC, Pool, Tennis, cottages, VC
Look for trends, max and min, times and fingerprints (ask Jacob)
Mauna Lani example
Energy lab example: consumption and production
Hands-on example: heat camera
Hot water container demo
Hot water heater demo
HPA campus environmental audit: LEED and LBC
Air Quality: CO2, ACH (air changes per hour), RH, temp (other schools look for Radon, VOCs, CO as well-we are passively ventilated, so these are likely to be low, we will test for them anyway)

- What is the night time energy load for our campus?
- How could we reduce this?
- Now that you have access to such fancy data gathering, what would be your plan for making HPA energy neutral?
