What information is needed to calculate the SRI of a material? choose 2
- A.
Thermal gradient
- B.
Reflectance
- C.
Emissivity
- D.
Thickness of the material
Correct Answer(s)
B. Reflectance
C. EmissivityExplanation
To calculate the Solar Reflectance Index (SRI) of a material, two pieces of information are needed: reflectance and emissivity. Reflectance refers to the material's ability to reflect solar radiation, while emissivity refers to its ability to emit thermal radiation. These two factors are crucial in determining the SRI value, which is used to assess a material's ability to reflect solar heat and maintain a cooler surface temperature. The thickness of the material and the thermal gradient are not directly related to the calculation of SRI.Rate this question:

- A.
Shortening the construction schedule
- B.
Reducing change orders
- C.
Decreasing the project costs
- D.
Reducing the amount of materials used
- E.
Determining the materials that best fit the project over the building's life
Correct Answer(s)
D. Reducing the amount of materials used
E. Determining the materials that best fit the project over the building's lifeExplanation
Completing a life-cycle assessment (LCA) of a building during the design process aids in reducing the amount of materials used by identifying areas where materials can be minimized or substituted. It also helps in determining the materials that best fit the project over the building's life by considering factors such as durability, maintenance requirements, and environmental impact. However, it does not directly impact shortening the construction schedule, reducing change orders, or decreasing project costs.Rate this question:

A school building consumes electricity from the grid at night while contributing energy back to the grid during the day from on-site solar panels, resulting in the school having no electricity costs. This is an example of:
- A.
Zero waste
- B.
Net-zero energy
- C.
Water balance
- D.
Carbon neutrality
Correct Answer
B. Net-zero energyExplanation
The given scenario describes a situation where a school building consumes electricity from the grid at night but contributes energy back to the grid during the day through on-site solar panels. This results in the school having no electricity costs. This aligns with the concept of net-zero energy, which refers to a building or system that produces as much energy as it consumes over a given period of time. In this case, the school's energy consumption and energy production are balanced, making it an example of net-zero energy.Rate this question:

What best defines the project boundary?
- A.
Portion of the project site submitted for LEED certification
- B.
Total area within the platted property line not including any non-constructed areas
- C.
Platted property line of the project defining land and water within it
- D.
Total area within the legal property boundaries of the site; this encompasses all areas of the site, including constructed and nonconstructed areas
Correct Answer
C. Platted property line of the project defining land and water within itExplanation
The project boundary is defined by the platted property line, which includes both land and water within it. This means that any area within the legal property boundaries of the site, whether constructed or nonconstructed, is considered part of the project boundary. This definition ensures that all areas of the site are included and accounted for in the project.Rate this question:
