Appliances
The
question we are trying to answer is you are building a new house. Your
contractor gave you
specs on four appliances, one refrigerator, dishwasher, water heater,
and clothes washer. Your
contractor will let you use a different appliance but you will have to
pay the difference in price. In
this section of the website we will be analyzing three Refrigerators,
Dishwashers, Water Heaters,
and Clothes Washers. Below will is a table that will describe each of
the appliances, comparing
them to one another.

Life Cycle Analysis:
This portion of the website will be to explain the life cycle analysis
of each appliance,
which is the best way to describe which appliance is the best.
-Life
Cycle Analysis is:
- (The Cost of The Appliance) + (Energy Used Per Year)+(Lifetime of
Appliance)+(Cost of Energy)+(Replacement
Costs)-(The Salvage Costs)
-For this project the lifetime of all appliances is 10 years.
-The cost of energy is 0.08 per kWh and $11.00 per MMBTU.
-There is no replacement for these appliances since we expect that all
will be able to work correctly for the entire 10 years.
-There is no salvage costs since we are not trading in any previous
appliances.
-Life
Cycle for Each Appliance:
-Appliance #1:
$1,103.60
-Appliance #2: $809.60
-Appliance #3: $4153.20
-Appliance #4: $938.00
-Appliance #5: $1588.4
-Appliance #6: $3012.80
-Appliance #7: $845.20
-Appliance #8: $1050.00
-Appliance #9: $3229.90
-Appliance #10: $3223.99
-Appliance #11: $982.80
-Appliance #12: $1379.60
Questions For Us to
Answer: By
the resources we have gathered, we have the information to complete
the following questions.
-How much additional money (if any) you need to invest to make your
house appliances more energy efficient?
-We have found that the only one of the appliances that we have
researched besides the ones given by the contractor
is the best for our new home. Therefore to answer this question we take
the price of the appliance(water heater) which
we found was more cost effective minus the price of the appliance(water
heater) that the contractor gave us. Therefore
the amount of money we have to spend is $179.99. To calculate this take
the price of appliance #10 minus appliance #3.
-What will the total energy savings (kWh) per year if you replace the
appliances with the energy efficient appliances?
-Actually the Water heater which we are using uses more kWh then
the other water heater, but is less expensive
because it uses gas. We used 2563.1 more kWh.
-How much money will you save per year if you replace the appliances
with the energy efficient appliances?
-To figure out this question we take the amount of money we save
over the 10 year period which is $929.21(to get this
amount you take the life cycle analysis of appliance #3 minus appliance
#10) divided by the number of life years of the
appliance which is 10 years. We will save $92.92 a year.
-What will be the overall (all appliances together) pay back period?
-To figure out the pay back period you take the amount of
additional money we spent($179.99) divided by the amount
the amount of money you will save per year as in the last
question($92.92). This will give us 1.94 years.
-How much money will you save over a period of 10 years.
-To figure this out we take the extra amount of money we have to
spend($179.99) and minus that from the total money
we will save which is ($929.21) which is equal to $749.22.
-We were suppose to put our kWh reduction into a simulator online, but
since my kWh usage went up i can not do this.
