One of the advantages of a window assembly that uses an inert gas in the air gap is: (a)Inert gases are not explosive. (b)The inert gas acts as an insulator and reduces the heat transfer through the window. (c)These windows can use single pane glazing. (d)Windows with inert gases are low cost.

For air conditioners and heat pumps, we size the wires and circuit breakers in accordance with the information printed on the label, not the simplified sizing charts that we typically rely on.
Should Low-E coatings be used in a hot climate area?
Core systems A. Use a central plumbing core, where plumbing areas are placed in close proximity to the water heater. B. Pipe hot water directly to each fixture or group of fixtures using smaller diameter piping when appropriate and as direct a path as possible. C. Are more expensive and take longer...
Demand-Initiated Recirculation Systems A. Consist of one continuous hot water supply loop that recirculates water throughout the home. B. Save water because they can reduce the wait time for hot water and return ambient-temperature water stored in the piping back to the heater. C. Are considered...
Manifold Plumbing Systems A. Uses larger, inflexible piping. B. Are also called parallel pipe or home run systems C. Use small diameter, flexible piping (such as PEX) that run directly to each individual fixture from a central manifold. D. Use of flexible piping allows these systems to be installed...
Trunk and branch systems A. Are the most common type of hot water delivery system. B. Are most suitable for larger homes in terms of maximizing hot water delivery system efficiency. C. Are characterized by one long, large diameter main line (i.e., the “trunk”) that runs from the water heater to the...
These lecture notes provide information about the improtance of system design and a balanced system.
These lecture notes provide information about the basic principles of heat transfer in buildings.
The “Four Ds”of controlling moisture and fungal growth resulting from moisture are: Deflection, drainage, drying, and durable components Diffusion, drainage, drying, and durable components Diffusion, deflection, drainage, and drying Deflection, diffusion, drainage, and durable components
These lecture notes provide information about how to control moisture in buildings.
Air sealing can unintentionally make the air inside a building: 1. Better 2. Worse
The Impact of Buildings Using Energy
In this video, the fundamental concepts of power and energy are described to provide a baseline understanding of these two important terms. Discussion includes dimensions, units, and example calculations associated with power and energy.
Video that details and explains Building and Energy Codes.
Basic Video on the on the introduction of Heat Pump systems
Using knowledge on heat pumps and HVAC systems from previous videos in this module, this episode dives deeper into the sample calculations for reducing the electrical load on a residential building.
Technical video on water heating. Not Heat pump specific. This video addresses ways to produce hot water and the energy impacts of using hot water in a building.
In this video, we will discuss the most common technologies for heating water, including storage, tankless, heat pump, and solar water heaters. We will also discuss best practices for saving energy with water heating systems.
