Question:
Design a home exterior to minimize heat gain during a summer day in Norfolk, VA. Requirements to be fulfilled:
- Home must be 196m2. One story is sufficient.
- All walls must be straight, but the shape may be any that the designer chooses.
- Walls for a one story home are 3m high.
- The interior must be maintained at 22oC.
Make reasonable assumptions for the following:
- Temperature and sun received.
- Heat generation within the home, including any parasitic electrical loads.
- Maximum number of people occupying the home. Make sure you can account for any gatherings that may occur such as a birthday party.
- Wall cross-section and layout. Calculate heat loss through the walls and roof.
Allowance must be made for six 1.5mx1m windows and two 1.5mx2m windows.
Discuss losses associated with doors. Do not include these in your design calculations.
Results should include:
- A sketch of the overall layout of the walls, including placement of windows. Discuss the choice of shape of the home and how this affects the heat transfer problem.
- A sketch of the wall cross-section.
- Calculation of thermal resistance of a wall with a window in it, as well as without a window in it.
- A discussion and supporting calculations of heat gained due to radiation.
- Estimate of the amount of heat required to be removed from the house in a day.
- Estimate of the cost to remove that heat based on reasonable thermodynamic analysis.
