*********** 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 77,790 BTU's.
The heating unit must handle 883 CFM's for proper heating.
The above figures include outside ventilation of 100 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 47,465 BTU's.
This translates into 4.0 tons of cooling.
The preferred cooling CFM is 1,423 CFM's for proper cooling.
For high humidity areas use 1,186 CFM's
For normal humidity areas use 1,423 CFM's
For low humidity areas use 1,661 CFM's
The above figures include outside ventilation of 100 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.

*********** Commercial analysis based on the following data ***********
There are 18 persons used for this analysis.
This area is being analyzed as a Residence.
There are 10 office equipment units used for this analysis.
There are 40 office lighting units used for this analysis.
*********** Structural analysis is based on the following data ***********
Based on 1055 square feet, total exposed outside wall area.
Wall construction is : 8 - 12 in. block w/19.
The wall has a heat transfer factor of .048 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 : Roof on exposed beams or rafters.
Ceiling insulation is : R-30.
The ceiling has a heat transfer factor of .033 heating and .033 cooling.
This analysis is based on a moisture content of 20 grains.
