Summary

• We have designed a Zero Energy Home that will produce all the energy it needs on its own. The home will have 1,085 square feet and will use sunlight and solar panels installed on its south roof to generate enough electricity to power the house and the appliances inside each year. This innovation will cut down on utility costs and at the same time will be a benefactor to the environment because it will use purely renewable energy.

Introduction

• Our assignment was, to design a Zero Energy Home that can produce all the energy it needs through the use of solar panels, and to configure the house and appliances inside so that we can fit just the right amount of solar panels on the south roof.

Customer Needs Analysis

• A house built for a family of four.• A house that can produce all the energy it

needs on its own through the use of solar panels, all placed on the south roof.

• A house that, while being energy efficient and good for the environment is still comfortable to live in.

External Research

• www.consumerspower.org – this site helped us decide on the number and type of appliances inside the house so that we could calculate our monthly KWh number

• www.writing.colostate.edu – this site showed us how to write a technical report

• www.sunelec.com www.homedepot.com www.globalindustrial.com – these sites gave us three examples of solar panels and helped us decide on the right one

External ResearchWashing Machine

Payback Time:

Whirlpool vs. Kenmore: ($1,000.00-$613.99)/ ($55.25-$54.26) = 389.91 yearsWhirlpool vs. GE: ($875.00-$613.99)/ ($55.25-$48.65) = 39.55 years

Based on our research we are picking the Whirlpool WTW6800W*+ as the washing machine for our ZEH. We have come to this decision based on the fact that the Whirlpool is a lot cheaper than the other two washing machines. In addition, despite the fact that the total cost of utilities is slightly higher for the Whirlpool, the payback time is exceptionally high.

External Research

Light Appliance

Based on the data above, we decided to pick LED lights as our choice of lighting because, LED lights are most efficient and have the longest lifetime out of all three light appliances.

Calculations• 100-Watt Solar Panel – (.100 KW)(5 hours)= .5 KW/day• .5KW/day (30 days)= 15KW/month (1 Solar Panel)• Estimated Monthly KW Usage: 2,288 KW• 2,288/15= 152.5333333 – We need 153 Solar Panels• 100-Watt Solar Panel Dimensions: 40.8 in. long by 20.7 in. wide (Surface

Area = 844.56 sq. in.)• South Roof Dimensions: 35 ft. long by 26 ft. wide (420 in. by 312 in.) • Surface Area of South Roof = 131,040 sq. in.• 131,040 sq. in. / 844.56 sq. in. = 155.1577153• We have enough room for over 153 Solar Panels.

Final Design Description

• We designed a Zero Energy House that's 35 ft. long by 31 ft. wide, with a surface area of 1,085 sq. ft. The house has 7 rooms which include, a kitchen, dining room, bathroom, laundry room, living room, and 2 bedrooms. The walls inside the house are 1.5 ft. wide and 9 ft. high. The house has 153 solar panels placed on its south roof. The south roof is 35 ft. long by 26 ft. wide, with a surface area of 910 sq. ft. (131,040 sq. in.). The north roof is 35 ft. long by 8 ft. wide. The two roofs are slanted away from each other. All 4 sides of the house have windows that are 4 ft. long by 3 ft. wide, with a surface area of 12 sq. ft. The south side has 8 windows, the north side has 4 windows, and the east and west sides both have 3 windows.

Conclusion

• After much work, we have completed our design for a Zero Energy Home that produces all the energy it needs on its own. We have configured the dimensions of the house and the size and number of the appliances inside to yield an appropriate Kilowatt number that allows for just the right amount of solar panels so that the house produces 100% of its energy. In addition, we also configured the floor plan so that its occupants can live comfortably.
