| How can Energy in the Home be Transferred Usefully and Wasted? | -Usefully: Radiators [Things that give out Heat]
-Wasted: Windows [Things that Lose the Heat] |
| How can Homes be Better Designed to Lose Energy? [1] | 1. Loft Insulation Fibreglass wool be Laid on the Loft Floor and Ceiling = Less Energy leaving the House via Conduction and Convection
2. Hot Water Tank Jacket: Simply reduces Conduction [Water is Hot]
3. Double Glazing: 2 Layers of Glass, with an Air Gap reduces Conduction
4. Thick Curtains: Reduces Heat Loss by Convection and Conduction through the Windows
5. Draught-Proofing: Simply strips of Foam and Plastic around the Door and Windows that stops the Hot Air from going Out. |
| How can Homes be Better Designed to Lose Energy [2] ? | 6. Cavity Walls and Cavity Wall Insulation: Two layers of Bricks + a Gap reduces Conduction, but not really Convection in the Gap, so Squirting the Insulating Foam in the Gaps can Trap Pockets Air |
| How can the Energy be Reduced, from Hot Water Pipes? | -Covering the Pipes with the Insulation reducing Conduction and Convection
-Painting them White, reduces Radiation
-Making them as Short as Possible so that the Water doesn't spend a lot of Time in the Pipes
-Making them as Wide as Possible, meaning it has a Smaller Surface Area to Volume Ratio. [Less Volume of Water is next to the Pipe --> Less Conduction] |
| How can the Thermal Conductivity Factor in making the Building most Efficient? What about Thickness? | -If a Material has a High Thermal Conductivity, then that means it will have a High Rate of Transfer of Heat.
-If a Material is very Thick then the Rate of Transfer is Lowered down |
| How and Why is Reducing Friction important? | -Friction in a System that lead to Energy Loss, via Heating
-This can be Reduced using Lubrication, or changing the Shape of an Object |
