windows with a low U-factor and a low SHGC, sealing all air leaks in the building envelope, sealing all duct connections, and balancing the HVAC system

During the pre-construction meeting, the homebuyer tells you that one of his biggest complaints with his last home was that the second-floor bedrooms were very difficult to cool in the summer. Which of the following best describes construction practices that would help prevent this performance issue?

a tightly sealed home, depressurized interior, and naturally vented combustion appliances

Backdrafting can occur in which of the following scenarios?

controlling the infiltration of water vapor from the exterior to the interior

If you are building in a humid climate, on which of the following should you focus the most?

All help to guarantee low utility costs for the homeowner.

Increased thermal insulation in the walls and attic, air sealing of wire penetrations through framing, and the use of housewrap all are related in what way?

The HVAC system is properly balanced to deliver sufficient airflow. The windows to be installed are the proper U-factor and SHGC for this climate. Proper framing and structural reinforcement is added to resist wind loads.

The plan you are about to build includes a two-story living room in which one of the walls is completely windows. What should you be concerned with to avoid building performance issues?

Your customer will expect all of the options.

Upon deciding to buy a new home, which of the following performance expectations is your customer likely to have?

blower door test

What test can be described as a fan attached to an envelope penetration that will vary airflow rate along with a pressure sensor?

both wind-driven rain and air leakage

When installed correctly, housewrap is effective at controlling what?

Building inspectors aren't focused on homeowner satisfaction; their primary responsibility is to make certain that the homes you build are safe for your customers.

Which of the following best describes the responsibility of your local building inspector?

hurricane clips and flitch plates

Which of the following construction practices can be used to reinforce the home against wind and seismic loads?

increased complexity of floor plans and elevations

Which of the following have contributed significantly to an increase in building performance issues?

careful planning to align all roof trusses, floor joists and studs to reduce framing materials

Which of the following practices alone can reduce drywall cracking and nail pops, use less jobsite labor, and reduce the HVAC equipment size?

All soil conditions require foundation drainage.

Which of the following soil conditions require drainage to relieve groundwater pressure against the home's foundation?

housewrap with taped seams, windows with a U-factor of 0.30, and foundation anchor bolts

You're going to start building homes in an area where the environmental conditions are often quite cold and rainy, with moderate wind, and relatively high seismic activity. Which of the following construction practices will be the most successful in these conditions?

filter fabric and gravel over rigid foundation drainage tile, rigid insulation with taped seams, and continuous tie-downs

You're going to start building homes in an area where the environmental conditions include moderate temperatures with high rainfall, relatively high wind, and moderate seismic activity. Which of the following construction practices will be the most successful in these conditions?
