Audience?

´ What type of buildings do you manage ? Size…

´ Do you know how much you spend in utilities ? Hydro, NG, others ?

´ How many employees ? Rooms, parking spots?

´ Who knows what these are:

´ Solar PV System…

´ CoGeneration…

´ Smart-Tech…

…Today’s Cost?Time-of-use (TOU) Prices

CoGeneration

´ Meant for larger buildings

´ Uses NG

´ It can generate:

´ Electricity

´ Heat, steam

´ Chilled air or water

´ It can have ~92% efficiency

Case StudyResort in Caribbean

Night ~ 700KWpx 12h/day = 12.0 MWh/day

x 12h/Night = 8.4 MWh/Night

20.4 MWh/day or 20,400,000 Wh/day

+

Using the map for average solar hour radiation, USVI gives us average of 5.6 hours of full sun per day...

2 MW array x 5.6 h ~= 11.2 MW/h of power production

Calculations (estimated)

Day ~ 1MWhpConsumption:

Based on a 2MW number, then 2MW/300W panels ~= 6720 Panels

Confidential

Preferred areas for Solar PV Installation

- Fuel Tank for ground mount

- 1 & 2 = Parking area for carport

- 3 = Left Parking area for ground mount

- TE = GEN Room, are to be used for roof mount

- CB = to be used for roof mount

- A-D = to be used for roof mount if necessary

- E-H = Will not be used

- MPC = Will not be used

Confidential

Preferred areas for Solar PV Installation

- Fuel Tank layout

- 3, Left Parking area layout

2865 x 310 W = 888,150 W

Electric Car

´ 133Km with 24KWh battery

´ A 66.5Km daily trip to work and back would need 12KWh+ of battery power

´ 8,000,000 cars in ONT, ½ are daily commuters to work = 4M cars

´ Lets further say 1/2 are carpooled = 2M cars traveling daily bases to work and back.

´ Every day 12kWh x 2,000,000 = 24,000,000kWh/day or 24GWh/day has to be produced to just cover car charging.
