Which of the following is NOT considered when calculating full-time equivalent (FTE)?
- A.
Full time employees
- B.
Building occupancy
- C.
Students, customers or visitors
- D.
Part time employees
Correct Answer
B. Building occupancyExplanation
Building occupancy is not considered when calculating full-time equivalent (FTE) because FTE is a measure of the total number of hours worked by full-time employees. It is used to determine the number of full-time employees that would be needed to perform the same amount of work as the current workforce, taking into account both full-time and part-time employees. Building occupancy, on the other hand, refers to the number of people present in a building at any given time and is not directly related to the calculation of FTE.Rate this question:

A commercial office building with a footprint of 70,000 square feet has an overall site area of 200,000 square feet. The site is in an urban setting and the zoning requirement mandates a minimum of 20% of the net lot area must be public open space. The project design includes 15,000 square feet of pedestrian oriented hardscape and 18,000 square feet of vegetated open space. Does this project satisfy requirements for SS Credit 5.2 Site Development?
- A.
Yes
- B.
No
- C.
Not enough information
Correct Answer
B. NoExplanation
To determine if the project satisfies the requirements for SS Credit 5.2 Site Development under the LEED rating system, we need to calculate the percentage of the site area that is dedicated to public open space.
First, we calculate the total site area dedicated to public open space: Total public open space = pedestrian-oriented hardscape + vegetated open space Total public open space = 15,000 sq ft + 18,000 sq ft Total public open space = 33,000 sq ft
Next, we calculate the percentage of the net lot area that is public open space: Percentage of public open space = (Total public open space / Net lot area) * 100% Percentage of public open space = (33,000 sq ft / 200,000 sq ft) * 100% Percentage of public open space ≈ 16.5%
The zoning requirement mandates a minimum of 20% of the net lot area to be public open space. Since the calculated percentage of public open space (16.5%) is less than the required 20%, the project does not satisfy the requirements for SS Credit 5.2 Site Development.Rate this question:

A new bank project is implementing high energy efficiency strategies to support their goal to achieve 10 LEED points under EA Credit 1 Optimize Energy Performance. Process energy for the bank makes up 35% of the energy costs for the project. A whole building energy simulation resulted in $145,295 for the bank. What should the project team target as their design case energy cost savings in order to reach their EA Credit 1 Optimize Energy Performance goals?
- A.
$29,059
- B.
$94,440.75.
- C.
$50,853
- D.
$72,648
- E.
$101,707
Correct Answer
B. $94,440.75.Explanation
To calculate the design case energy cost savings, we need to determine the baseline energy cost (without energy-efficient strategies) and the proposed energy cost (with energy-efficient strategies).
Given that process energy makes up 35% of the energy costs for the project, we can calculate the baseline process energy cost:
Baseline Process Energy Cost = 0.35 * $145,295 = $50,854.25
Now, the proposed energy cost is the result of the whole building energy simulation:
Proposed Energy Cost = $145,295
Design Case Energy Cost Savings = Baseline Process Energy Cost - Proposed Energy Cost Design Case Energy Cost Savings = $50,854.25 - $145,295 = -$94,440.75
However, the negative value indicates that the proposed energy cost is already less than the baseline process energy cost, meaning there are significant energy cost savings with the implemented energy-efficient strategies.
Therefore, the correct answer is $94,440.75.Rate this question:
