Select one of the following:

  • True
  • False

Explanation

Question 2 of 20

1

One can assume that individual room heating loads are proportional to room floor area.

Select one of the following:

  • True
  • False

Explanation

Question 3 of 20

1

The R-value of a material is not directly proportional to its thickness.

Select one of the following:

  • True
  • False

Explanation

Question 4 of 20

1

Many residential and commercial buildings have concrete floor slabs rather than crawl spaces or full basements. Downward heat losses are relatively small from interior areas of the floor slab.

Select one of the following:

  • True
  • False

Explanation

Question 5 of 20

1

The U-value of any material or assembly is simply the reciprocal of the R-value of that material or assembly.

Select one of the following:

  • True
  • False

Explanation

Question 6 of 20

1

Heat is lost through all building surfaces that separate heated space from unheated space.

Select one of the following:

  • True
  • False

Explanation

Question 7 of 20

1

It is relatively easy to assess the location and magnitude of all the air leakage paths in a typical building.

Select one of the following:

  • True
  • False

Explanation

Question 8 of 20

1

The number of heating degree days that accumulate in a 24-hour period is the difference between 72 F and the average outdoor air temperature during that period.

Select one of the following:

  • True
  • False

Explanation

Question 9 of 20

1

Knowing how many MMBtu a building requires over a typical heating season is not of much use to most owners.

Select one of the following:

  • True
  • False

Explanation

Question 10 of 20

1

A boiler, furnace, or small space heater operating on the same fuel, at the same assumed conversion efficiency, would produce the same estimated annual heating cost.

Select one of the following:

  • True
  • False

Explanation

Question 11 of 20

1

The heating load is __________ of heat flow from the building to the outside air.

Select one of the following:

  • a rate

  • the quantity

  • the cost

  • one unit

Explanation

Question 12 of 20

1

The proper approach is to perform a heat load calculation __________.

Select one of the following:

  • factoring seasonal requirements

  • for each room

  • for the entire building

  • based on the owner's usage

Explanation

Question 13 of 20

1

An object's thermal __________ can be defined as its thickness in the direction of heat flow divided by its thermal conductivity.

Select one of the following:

  • reactivity

  • reproduction

  • reciprocity

  • resistance

Explanation

Question 14 of 20

1

Heat flow from a basement or slab-on-grade foundation is determined by complex interactions between the building, the surrounding soil, insulation materials (if present), and the __________.

Select one of the following:

  • depth of the foundation

  • orientation of the structure

  • air temperature above grade

  • planned usage of the room

Explanation

Question 15 of 20

1

All building surfaces that separate heated space from unheated space (walls, windows, ceilings, doors, foundation, etc.) are called the __________ of the building.

Select one of the following:

  • thermal envelope

  • heat load variables

  • resistance factors

  • thermal qualifiers

Explanation

Question 16 of 20

1

The U-value of any material or assembly is simply the reciprocal of the __________ of that material or assembly.

Select one of the following:

  • heat load

  • temperature

  • exposure

  • R-value

Explanation

Question 17 of 20

1

In addition to conduction losses, heat is also carried out of buildings by uncontrolled air leakage. This is called __________ heat loss.

Select one of the following:

  • anti-thermal

  • infiltration

  • insulation

  • environmental

Explanation

Question 18 of 20

1

Select one of the following:

  • prognostication

  • thermometers

  • historical records

  • degree days

Explanation

Question 19 of 20

1
