These lecture notes provide information about how weather barriers are different than vapor barriers.
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...

Which of the following is NOT a factor that affects heat transfer? A. Temperature difference B. Time C. Lumen level D. Surface area
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.

This image shows some of the more complex window componetns of a double pane window.
Make a sketch showing a “double-pane” window and label key features. Include as much information about each window element as possible.
What are energy efficient window design strategies for a building in cooling-dominated climate? (circle all that apply) (a). Increase window size on the north façade while maintaining the same overall building window ratio (b). Increase window size on the south façade while maintaining the same...
What are the energy efficiency design strategies for a building in heating-dominated climate for energy efficiency? (circle all that apply) (a). Increase window size on the north façade while maintaining the same overall building window ratio (b). Increase window size on the south façade while...
What is the most airtight window operation method? (a.) Double hung (b.) Casement (c.) Fixed (d.) Awning
This video describes how window U-value is calculated.
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?
Guidance for home owners who recently installed a heat pump system. This informs homeowners how to operate and maintain the heat pump system.
