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...
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 “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.
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
In general terms (i.e., not required to list the specific code and standard), explain for a specific type of natural disaster (e.g. earthquake or flood) how local codes and industry standards could prepare and protect a building from a natural disaster.
Over half of the indoor air quality problems result from ____________________? 1. Increasing toxicity of mold 2. Inadequate ventilation 3. Excess dust due to insulation 4. Low oxygen levels.
Evidence of moisture problems in a building can include: Damp feeling, odors; mold and mildew; peeling paint and sweating pipes Shrinking, warping, rotting wood; drawers that stick Condensation, frost and ice dams on windows Discoloration corrosion, oxidation, or rust of building materials All of...
What are the conditions that must exist for mold growth to occur? Mold spores must be present. Temperatures must be between 35°F and 100°F. A naturally occuring food source must be available. Moisture must be available in sufficient quantities. All of the above
