- *********** HEATING ***********
-
- The heating outside design temperature is 10 degrees fahrenheit.
- The heating inside design temperature is 72 degrees fahrenheit.
- The heating temperature differential is 62 degrees fahrenheit.
-
- The heat loss for this building is 92,994 BTU's.
-
- The heating unit must handle 1,056 CFM's for proper heating.
-
- The above figures include outside ventilation of 20 CFM's.
-
- Any heating unit must be rated as close as possible to the heat loss
- calculated in this study, but not less than that amount.
-
- The above CFM allows an 80 degrees rise in inlet to outlet air temperature.
-
-
- *********** COOLING ***********
-
- The cooling outside design temperature is 95 degrees fahrenheit.
- The cooling inside design temperature is 72 degrees fahrenheit.
- The cooling temperature differential is 23 degrees fahrenheit.
-
- The heat gain for this building is 39,880 BTU's.
-
- This translates into 3.3 tons of cooling.
-
- The preferred cooling CFM is 1,196 CFM's for proper cooling.
-
- For high humidity areas use 997 CFM's
- For normal humidity areas use 1,196 CFM's
- For low humidity areas use 1,395 CFM's
-
- The above figures include outside ventilation of 20 CFM's.
-
- Any cooling unit must be rated as close as possible to the heat gain
- calculated in this study, but not less than that amount.

- *********** Structural analysis is based on the following data ***********
-
- Based on 1055 square feet, total exposed outside wall area.
-
- Wall construction is : Frame wall w/R-11.
- The wall has a heat transfer factor of .07 heating or cooling.
-
- Based on 2 doors, assuming 20 square feet per door.
-
- Door construction is : Solid wood, no storm.
- The door has a heat transfer factor of .713 heating and .46 cooling.
-
- Based on 345 sq. ft. of window glass.
-
- All window construction is : Single glazed, plain, no storm.
- All windows have a heating factor of 1.505
-
- There are 75 sq. ft. facing north, with a cooling factor of 30
- There are 0 sq. ft. facing northeast/west, with a cooling factor of 65
- There are 195 sq. ft. facing east/west, with a cooling factor of 90
- There are 0 sq. ft. facing southeast/west, with a cooling factor of 80
- There are 75 sq. ft. facing south, with a cooling factor of 50
-
- Based on 1800 square feet total floor area.
-
- The foundation is : Over uncond. basement/enclosed crawl.
- The floor has a heat transfer factor of .312 heating and 0 cooling.
-
- The ceiling is : Ceiling under/vent. attic/uncond. room.
- Ceiling insulation is : R-11.
- The ceiling has a heat transfer factor of .088 heating and .083 cooling.
-
- This analysis is based on a moisture content of 20 grains.
