The Team

            Project Overview
Goals:
  • To learn about the energy usage within a home
    and how to make it more sustainable
  • To critically think and understand how to use
    appliances to create a Zero Energy Home
  • To work together as a team to make this dream
    home possible



                                                    3
                  Researching
• Common traits we found in ZEH
  •   Solar Water Heaters
  •   Large amounts of South facing windows- Passive
      Solar
  •   Photovoltaic System
  •   Energy efficient appliances




                                                       4
         Styrofoam Experiment
• Through this we learned how even the
  slightest opening (about 1 inch) causes more
  air changes per hour (air leakage)
• Based off of this box- a larger R value for wall
  and ceiling along with a more tightly sealed
  house will cut down the air changes per hour




                                                     5
Decisions For Our Home
           • Less floor levels leads to
             an easier time
             conserving energy for
             the whole home
           • Larger R value for
             insulation helps
             conserve heat
           • Two Northern wings
             included to increase the
             aesthetic appeal of the
             home

Physical Model




                 20
       Andrew’s Favorite Part
• Putting up the walls to the house
• “It was awesome to finally see the whole
  house coming together physically.”




                                         21
           Josh’s Favorite Part
• “Making the Sketch Up Model was the
  highlight for me. The computer stuff is what I
  am best at so doing that was great.”




                                                   22
           Kurt’s Favorite Part
• I thought it was great working with the team
  and sharing ideas. Everyone communicated
  very well with each other, which made
  transferring the house from the computer to
  the physical model easy.




                                                 23
          Steve’s Favorite Part
• “I really enjoyed designing the house and
  sketching it out on paper. It was fun being
  creative and planning out the rooms and the
  size of everything.”

                            Review
Challenges                           Important Aspects
• Putting together the roof          • U-shape with wings
   • With so many measurements         branching out North
     and different parts, building
     the physical model required     • One story
     so much effort                  • Zero Energy
• Combining everyone’s
                                     • Energy Star Appliances
  thoughts of what to have in
  this home                          • 7kW PV system
• Making truly a Zero Energy
  Home, so many calculations
  made it challenging

                                                                25
                Conclusion
• Lesson Learned-
1. How to keep track and reduce energy use
   within a home
2. How our roles as engineers is to not only do
   our jobs but to do them in a sustainable and
   eco-friendly fashion
3. How to work together as a team and put
   everyone’s thoughts and points of view into
   the decision making process of this home
