Which of the following does not affect the demand for cooling in a given space? Select one:

List at least three variables (structures) that affect the loss of heating and cooling in the building (house).

During winter, when people are in a well-insulated house,they usually feel comfortable if the air temperature is near22°C (72°F). If you have ever spent a night in a poorly insulatedcabin in winter, however, you will recognize that paradoxically,when people are in poorly insulated buildings, they often feelchilly even when the air inside is heated to 22°C or higher. Oneimportant reason for the difference in how warm people feel inthe two sorts of buildings is that even if a well-insulated andpoorly insulated building are identical in the air temperatureinside, they differ in thermal-radiation heat transfer. Specifically,a person standing in the two types of buildings experiencesdifferent heat exchange by thermal radiation in the two. Explainhow thermal-radiation heat transfer accounts for the sense ofchill in the poorly insulated building. (Hint: Think of the outerwalls of the two types of buildings, and think specifically of thetemperatures of the interior surfaces of those walls.)

Calculate the relative humidity if the psychrometer reads 20°C for the dry air temperature and 15°C for the wet air temperature. Or = 59% Or = 52.5% Or= 51% Or = 66% %3D
