Problem Set
Circle all letters that apply to PEX (cross-formulated polyethylene): A. PEX is a soft plastic that comes in coils. B. PEX is remarkably durable within a wide range of temperatures, pressures, and chemicals. C. PEX is flexible. D. PEX stretches to accommodate the expansion of freezing water and then...
Problem Set
Explain how the “robustness” feature of resilience should be applied to prepare for or respond to a natural disaster.
Teaching Material
This series of videos explains everything from basic types of windows, to the physics associated with cold and warm weather window performance.
Lecture Notes
These lecture notes provide information about how weather barriers are different than vapor barriers.
Problem Set
Weather barriers (aka air barriers) differ from vapor barriers in that: Weather barriers are breathable and go on the outside of wall sheathing, while vapor barriers are not permeable and go on the interior side of wall insulation. Weather barriers are not breathable and go on the outside of wall...

Problem Set
Which of the following is NOT a factor that affects heat transfer? A. Temperature difference B. Time C. Lumen level D. Surface area
Problem Set
Heated air rises because: A. the molecules in warm air move more quickly and therefore are more buoyant. B. warm air is less dense and therefore is more buoyant. C. cold air is less dense and therefore is more buoyant. D. cold air falls, pushing the warmer air out of the way.

Problem Set
What is the most airtight window operation method? (a.) Double hung (b.) Casement (c.) Fixed (d.) Awning
Problem Set
A. Would a building in a cold climate benefit more from a window with a high U-value or a low U-value? B. Would a building in a hot climate benefit more from a window with a high SHGC or a low SHGC?
Teaching Material
