Natural Cash: An
Presented by Nolan Jones, Tommy Horne and Lin Lau
Current methods are harmful
Purpose of our study:
Investigate alternate energy
Reduce carbon emissions.
• First, determine building to analyze.
• School, house, store, etc.
• Find out how much is spent on energy,
or how much is used, if not already
• Research savings with desired energy
saving mechanism, e.g. solar panels.
• Analyze data, conclude.
The three most common forms of natural energy
are solar, from the sun; wind; and hydro, from
They all come with some drawbacks, and
Hydro: Must be near a moving body of water.
Solar: Must have direct sunlight.
Wind: Must have open air.
The main focus with all three natural energies is
that they all provide free, clean energy.
Marcus Welcome Center
• Open on May 2005.
• Center provides enrollment
information to possible students, and
serves as a meeting place.
•Admission of scholarship and
•Only building on campus with its own
centralize system of energy.
•Building of analysis.

High Medium Low Questions Answers
Energy energy Energy
How are the computers
Controlled by users, but always turn off
for security purposes
How are lights controlled? Controlled by motion sensor or infrared
detectors, so they shut down
completely without occupants in the
room. Larger common areas are
controlled by timers, except for some
lobby light that are kept on for security
How are AC/heat controlled? Building heating/cooling systems are
controlled by central energy
management system, which has night
setback temperatures for energy
The Marcus Welcome Center also
recycles office paper, magazines,
newspaper, aluminum cans, and
Solar panels work by converting
the energy from the sun into the
electricity we use to power our
The sun’s rays “agitate” the
Energy is transferred and
Some will store in battery.
Some systems will put excess
power back in grid, and power
meter will reverse: lower bill!
Solar tiles work in much the same way.
Long lasting—up to forty years.
Disadvantages of solar in general:
Fragile- work in progress.
No sun—no power.
Roof—if sun is on other side, you get
Wind Turbines have angled blades
that spin in wind.
Kinetic energy is transferred to
Most wind turbines lose about 5% in
Slow down in high speed wind.
Supply direct energy when
battery is full.
Can also put excess directly into
power grid, reducing power bill.
Many safety features.
Disadvantage: Moving parts—high

More power means higher cost, but it’s worth it.
Cost to take MWC off power grid: $3,134,365.63 .
Government tax reliefs:
30% yearly tax deduction.
100% property tax reduction.
Post Incentive (after tax taken out):
Cut in half to half savings.
Payback rate always same: 31.41 years.
Information based on nine dollars per kilowatt.
Currently produce 902,881 pounds of carbon dioxide.
Equivalent to driving 1,000,501 miles.
To offset would require:2,257 trees.

To conclude, the Marcus Welcome Center is
already very efficient, and the cost to install solar
panels or wind turbines is not economically
viable, because by the time the costs are paid off,
new, more efficient and cheaper equipment
would already be on the market.
