Figure 4-37a. Thermal resistance vs design winter temperatures for two vertical lengths of insulation for barrack buildings
(from electrical analog analyses)41. See figure 4-36 for legend. Note: TM 5-810-14, Mechanical Design-Heating,
Ventilating and Air Conditioning, states: "1-03 OUTSIDE DESIGN TEMPERATURES. The outside heating design
temperature should be determined in accordance with TM 5-785/AFM 88-29. Winter design for military installations will
normally be based on the 97-1/2 percent dry-bulb temperatures tabulated in TM 5-785/AFM 88-29 and defined therein
under 'General Information'. " TM 5-785/AFM 88-29, defines this temperature as the dry bulb temperature which is
equalled or exceeded 97-1/2 percent of the time, on the average during the coldest three consecutive months.
