Aiken Info:


 * Heat-compare occupancy with usage
 * Data from Chuck Norton on the physical plant (Marc Rosenbaum?)
 * Solarium:
 * fan coil for heat to kick on
 * passive ventilation
 * no active heating
 * passive solar/south facing
 * **Possible Net-Zero Updates:**
 * motion sensors in hallways to sense occupancy
 * focus on retrofitting other Rub. buildings for energy efficiency
 * add timers on projectors
 * get mini-fridges out of professors private offices
 * turn off staircase lighting during the day-skylight
 * light redirecting blinds
 * copy room exhaust fans
 * change sensor fail switches (to not overheat)
 * capture solar electricity
 * plug loads
 * current solar output from solar is 17% min for LEED
 * bigger vestibule=higher airlock
 * infared sensors in rooms for ventillation and temp.
 * seperate ventillation and temperature systems
 * CO2 sensors=decreased air turnover
 * convection heat flow


 * The Gund Institute/Johnson House Tour Notes**
 * Pros
 * Recently refurbished
 * Insulation in walls


 * Double Pane windows
 * Cons
 * Front Door
 * Poorly Insulated
 * Light always on/ No Timer
 * Plasma TV
 * Always no/ No timer
 * Thermostat
 * Only ONE for the entire building
 * Solutions
 * Inexpensive fixes
 * Timers for lights/electronics
 * Costly fixes
 * New front door
 * Add a thermostat to second floor


 * Rubenstein Lab notes: **
 * Amount of energy used vs. time spent in lab?
 * walk-in cooler freezer (produces heat by cooling, capture in summer, release in winter?)
 * no automated lights- awareness of light switch
 * hallway lights and staircase lights- LED replace
 * skylight- light sensor
 * thermostat- adjustable, programmable
 * capacity sensors
 * hoods always on- energy recovery?
 * 2 water chillers in lab- insulation, efficiency?
 * compressed air- timer?
 * reverse osmosis water filter
 * nighttime offsets (temp, ventilation, lights)
 * ghost power, plugs on light, off switch connected to everything
 * ultra cooler
 * water pumps- store and use
 * replacing gaskets on doors
 * PV outside- Echo has solar panels but the lab is not hooked up to them

Tour 2 AUDIT: 1st floor- Staircase-
 * Lake water cooling
 * nighttime setbacks
 * OSRA occupied/unoccupied
 * compressor motor? cooling units
 * daylighting, sensors, setbacks
 * disable onside hallway light switch
 * **wireless sensors**
 * **maintenence on reverse osmosis water pump**
 * **Hoods setting to lowest**
 * **lighting retrofit-swap out the 40 bulbs from 32 watts to 28 watts; some already failing anyways (lighting hours?)**
 * ** 2 sensors, on on each side of the lab area- ultrasonic 500 sq. ft. each **
 * ** light logger **
 * ** downstairs **** work room w/ hood : light sensor, 50% standard over/under switch **
 * **50% sensor- rebates**
 * **mandatory low (LED?)**

Upstairs-
 * **Daylight sensors**
 * **permanently disable half of the lights? - Rich check**
 * **upstairs classroom- 207- teaching hood- shut off (broken?)**
 * **CO2 sensor instead of occupancy**
 * **programmable dimmers**
 * **skylight summer shading?**
