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.

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...
The definition of a balanced HVAC system is: A system that operates under neutral pressure, where the amount of air blowing out the supply ducts should match the amount of air getting pulled into the return ducts. A system that operates under positive pressure, where the amount of air blowing out...
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
Air sealing can unintentionally make the air inside a building: 1. Better 2. Worse
Identify and explain the role of 3 building-related stakeholders that are affected in a natural disaster.
1. Explain three benefits of air source heat pumps compared to fossil fuel heating systems.
1. True/False: A salesperson must remain consistent to his/her communication style, without taking into consideration the customer’s communication style. 2. True/False: Talking about the company’s expertise and experience regarding heat pump installations might be harmful for closing the sale.
1. As a technical expert in heat pump technology, you should have a ‘Design Questionnaire’ to go over with the customer. What is the purpose of the ‘Design Questionnaire?’ a. Assess if the building is appropriate for such a system, where to place the system, the size of the system, and an estimate...
1. The installation of a heat pump has both economic and environmental benefits. A heat pump reduces the amount of energy use and therefore energy costs. Also, switching from gas-powered heating to electricity-powered systems will avoid air pollution from burning natural gas.
1. Closing the heat pump installation deal might raise objections regarding which of the following? a. Capital investment cost of the system. b. Worries about the system working in the customer’s climate/location. c. Maintenance cost of the system. d. Aesthetics of the system. e. All of the above.
For the plumbing layout below, assuming all pipes are copper M and 3/4 inches in diameter (0.824 inches for the inner diameter), calculate the theoretical volume of water stored between the water heater and the farthest fixtures, to determine if the system can meet the EPA’s WaterSense® 0.5 gallon...
What is the most common cause of moisture failure in a building? Improper management of bulk water Air movement Evaporation Diffusion
What are some characteristics of gas fills?
Which type of low-emission coating is characterized by a low solar heat gain coefficient (SHGC), and a low visible transmittance (VT)?
Which of the following professionals need an understanding of building codes but do not apply building codes in their normal job duties? A. electricians B. plumbers C. realtors D. architects
