Transcript of Energy Management
Q-BLDG Marty Bruzikas, Chris Jones, Thierry George, Steven Steele, Steven Sims Purpose How is Energy Use Measured? To generate as much power as the current SPSU grid or through the means of more efficient technology in order to provide power for the building, while keeping the current power grid setup as a backup and sub-backup. Kilowatt/hour
1 kw/hr = 860 kilocalories
-Eventually want to provide for the campus
-If successful, excess generation is possible so we would be returning power to provider(s). What is a BTU?
16 oz -> 1°F
1 BTU = 1,055.06 J
3,412 BTUs = 1 kWh
1 MBTU = 1 Dth
1 cubic foot (ft3) ~ 1,028 BTU
1 cubic meter (m3) ~ 36303.3 BTU
100 cubic feet = 1 CCF What’s so important about BTUs?
We are talking kilowatts, aren’t we? Single Phase Electric
Energy Meter Electric Meters
Electromechanical (Standard Meter)
Numeric Display Meter
Solid State Electric Meters
Electronic Meter What devices are used to measure building energy consumption? Gas Meters
Diaphragm Gas Flow Meter
Turbine Flow Meter
Rotary Gas Flow Meter
Coriolis Gas Flow Meter
Ultrasonic Gas Meter Missed opportunities

Totals to about 3.15640 trillion kWh
Totals to ~ 689.9 billion cu m Annual Energy Outlook 2013
Projection for 2040 Electricity Consumption
3841 billion kWh -> 4930 billion kWh
Annual rate of +0.9%
42% -> 35%
790 billion kWh -> 903 billion kWh
13% -> 16% Solar Energy 10kw Only: $18,095.00
Produces 1500KW per week
1KW = 3412.142Btu’s
We would need 24 systems to be
100% self sustained
$480k to go 100% green Application of Sources
on the SPSU Power Grid These ideas are great, but how can we apply them to SPSU’s Electrical Grid?
Can thrive off of the CO2 while generating light as well as fresh air.
Parking Deck, road ways, classrooms, walkways.
Anywhere the piezoelectric crystals can be compressed. Present Lighting Annual lighting cost estimate
35% of electrical costs
2500 fixtures at 50 watts each
$50,000 annual maintenance Proposed Lighting Solutions Lighting I/O control via digital photocell for lobby in addition to occupancy sensors. (In progress)
LED lights (ideally for emergency lighting that is required to be on at all times) Backfeeding Power into the grid Batteries are expensive, toxic, cause pollution,
and have to be replaced about every five to seven years
The large added expense of batteries makes total generation less popular than the simpler peak shaving setups. On the other hand, as technology and demand advances,
power companies are required to buy any "negative" power that comes from home or business users References http://www.energyvortex.com/energydictionary/british_thermal_unit_%28btu%29__mbtu__mmbtu.html (BTUs)
