A building has a 9’ deep basement (foundation) wall that is 160’ long. The wall has no windows. On average, 8’ of the wall is below grade (underground). Assume an outside air temperature of 10°F, an inside temperature of 70°F, and an average ground temperature of 45°F.
a. Determined the rate of heat loss through the wall below grade if it is uninsulated.
b. Determine the rate of heat loss through the wall below grade if it is insulated with an R-value of about 12 hr*°F*ft2/Btu.
A commercial building is built on a slab on grade
foundation that is a 120’ by 48’ rectangular shape.
Assume the outside design temperature is -5°F. Determine the rate
of heat loss through the exterior
edge of a concrete slab.
a. For an uninsulated slab edge perimeter.
b. For a slab edge perimeter insulated with 1” of perimeter insulation (an R-value of about 2.5).
c. For a slab edge perimeter insulated with 2” of perimeter insulation (an R-value of about 5).

Building rapport as a leader allows for the leader to develop a
deep sense of respect, trust and honesty with their team. These
shared understandings ultimately lead to a mutual understanding and
allow team members to feel heard and seen. Rapport is in an
important factor in developing overall trust within teams. By
considering all points of view and listening to understand, leaders
increase their effectiveness (Manning 2014, 41). Leaders who focus
on gaining their teams trusts, will also be...
