    What is the safest type of glazing to use in a sidelight adjacent to a door?

    • Ceramic

    • Wire

    • Float

    • Tempered

    Correct Answer
    A. Tempered
    Explanation
    Tempered glass is the safest type of glazing to use in a sidelight adjacent to a door because it is designed to be stronger and more resistant to breakage compared to other types of glass. Tempered glass undergoes a special heating and cooling process that increases its strength and makes it shatter into small, rounded pieces when broken, reducing the risk of injury. This makes it ideal for areas where safety is a concern, such as near doors where accidental impact or breakage is more likely to occur.

    An interior designer has just finished reviewing the plans for a large office suite when the building departments states that the lighting budget has been exceeded. If the design is composed of 80% fluorescent lighting and 20% incandescent lighting what is the BEST course to begin redesign?

    • Reduce the number of luminaries by spacing them farther apart.

    • Substitute all incandescent lights with fluorescent lights.

    • Change to a task-ambient lighting system.

    • Investigate whether lamps with higher efficacies will bring the design within the budget.

    Correct Answer
    A. Investigate whether lamps with higher efficacies will bring the design within the budget.
    Explanation
    The best course to begin redesigning the office suite in order to bring the lighting budget within limits is to investigate whether lamps with higher efficacies will help achieve this. This means exploring the possibility of using more energy-efficient lamps that can provide the desired lighting while consuming less power and therefore reducing costs. By considering lamps with higher efficacies, the interior designer can potentially find a solution that meets both the lighting requirements and the budget constraints.

    Exit access corridors in nonsprinklered building must have a rating of 

    • 30 mins

    • 45 mins

    • 1 hour

    • 2 hours

    Correct Answer
    A. 1 hour
    Explanation
    Exit access corridors in nonsprinklered buildings must have a rating of 1 hour. This means that the corridors should be able to resist fire for at least 1 hour, allowing occupants enough time to evacuate safely. This rating is important in ensuring that the exit routes remain protected and usable during a fire emergency. It provides sufficient time for people to exit the building and reach a safe location before the fire spreads and becomes a significant threat.

    If a material supplier says that adding his product to a wall assembly in a critical acoustic situation would increase the noise reduction (STC rating) between two rooms by slightly more than 3dB, what should the designer's reaction be?

    • Determine what the additional cost would be and the decide whether or not to use the product.

    • Thank him for stopping by, but explain that the amount of noise reduction his product provides does not make it worth the effort or cost.

    • Specify the product as longs as it does affect the construction cost by more than 5%

    • Inquire whether some modification can be made to the product to increase the rating to 6dB.

    Correct Answer
    A. Thank him for stopping by, but explain that the amount of noise reduction his product provides does not make it worth the effort or cost.
    Explanation
    The designer's reaction should be to thank the material supplier for stopping by, but explain that the amount of noise reduction his product provides does not make it worth the effort or cost. This response suggests that the designer acknowledges the supplier's input but recognizes that the minimal increase in noise reduction does not justify the additional cost and effort of using the product.
