QUESTION 61
During the early stages of a LEED for Schools project, the team was able to reduce the number of lighting fixtures in classrooms by 25% because the project team selected paint color whose light reflectance value was 75% instead of the initially proposed 64% value. This strategy is an example of applying which of the following credits to the project?

Innovation Credit, Innovation

Integrative Process Credit

Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control

Materials and Resources Credit, Interiors Life-Cycle Impact Reduction

QUESTION 62
The project landscape architect suggests reducing the area planned for surface parking and replacing it with additional vegetated space. What benefit would this strategy provide to the owner?

Increases the rainwater infiltration capacity

Decreases the amount of bicycle parking that must be provided

Increases the overall SR (solar reflectance) of the hardscape area

Decreases the required amount of on-street parking that must be provided

QUESTION 63
Which of the following groups of documents is most likely to support both Indoor Environmental Quality Credit, Thermal Comfort, and Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control?

Architectural floor plans, mechanical plans, lighting plans

Photometric plans, mechanical schedules, lamp specifications

Lighting plans, surveys of occupants, sequence of operations

Surveys of occupants, photometric plans, mechanical schedules

The most likely group of documents to support both Indoor Environmental Quality Credit, Thermal Comfort, and Indoor Environmental Quality Credit, Interior Lighting, Option 1. Lighting Control is C, lighting plans, surveys of occupants, sequence of operations.
Lighting plans show the layout and type of lighting fixtures, as well as the lighting controls, such as dimmers, timers, occupancy sensors, or daylight sensors. Surveys of occupants provide feedback on the satisfaction and comfort level of the building users regarding the thermal and lighting conditions. Sequence of operations describes how the mechanical and lighting systems operate and respond to different scenarios, such as occupancy, temperature, or daylight levels.
These documents can demonstrate that the project meets the requirements for both credits, which are:
For Thermal Comfort, the project must design the HVAC systems and the building envelope to meet the requirements of ASHRAE Standard 55-2010, Thermal Environmental Conditions for Human Occupancy, or a local equivalent, and provide individual thermal comfort controls for at least 50% of the individual occupant spaces, and group thermal comfort controls for all shared multi-occupant spaces1.
For Interior Lighting, Option 1. Lighting Control, the project must provide individual lighting controls that enable adjustments to suit individual task needs for at least 90% of the individual occupant spaces, and provide lighting system controls for all shared multi-occupant spaces that allow occupants to adjust the lighting to meet group needs and preferences2.
The other groups of documents are less likely to support both credits, because:
Architectural floor plans, mechanical plans, and lamp specifications do not show the lighting controls or the occupant feedback.
Photometric plans, mechanical schedules, and lamp specifications do not show the thermal comfort design or the occupant feedback.
Surveys of occupants, photometric plans, and mechanical schedules do not show the lighting controls or the thermal comfort design.

Any changes in schedules during peak times, or for different seasons, peak-usage days of the week, and times of day

Any changes in schedules or setpoints focusing on only the hottest and coldest periods of the seasons, peak-use days of the week, and times of day

QUESTION 65
