HMW Questions• 10/11 HMW Questions:• HMW make sure our house has good insulation?• HMW make an efficient use of heat?• HMW convert the solar energy?• HMW keep a steady heat source?• HMW use windows effectively?• HMW make the heat last longest?• HMW use dark colors to our advantage?• HMW use materials with a high thermal mass?• HMW use our knowledge of the sun to our advantage?
Brainstorming• Some of the ideas we came up to convert the solar energy (into heat)?• Dark Colors• Solar Panels• Insulation in Walls• Full (constant) contact with sunlight• Warm Material-Fabric, Felt• Amplifier-Magnifying Glass• Water
Brainstorming• Some of the many ideas we came up with to make sure our house has good insulation were• Dome Roof• Latch for thermometer• Foam• Wool• Insulation in Floor• Put it out of the shade of trees-Open Space• Black Box• Double Wall with insulation in between
Prototyping-Phase 1- Basic Idea: - Four Walled House - Double Walls - Towels (Insulation)
Prototyping-Phase 2- Dark Surface Idea: - Painting Everything Black - Walls - Insulating Foam - Using Black Duct Tape
Prototyping-Phase 3- CD Design - Four-way CD Pyramid - CD’s on inner Walls
Prototyping-Phase 4- Finding Heat Conservers - Collecting Stones - Spreading them in the bottom of the house
Prototyping-Phase 5- Allowing more light in: - Adding CD’s on top
Prototyping-Phase 6- Final Touches - Sealing plastic covering - Attaching roof to base - Adding foam to bottom to reduce conduction
Testing• Our goal was to get the base temperature of the House above 68 degrees• We achieve a temperature of 12-15 degrees• The final result was great but disappointing because we found out how to make a solar house colder than the outside temperature, yet we never achieved our goal.
