In Behind the Intent, add the following paragraphs at the end:
Daylight and views are especially important in a residential building as these buildings may be inhabited continuously. For Multifamily, Option 1: Daylight Measurements requires minimum access to daylight in each living space. Since all the spaces may be frequently used by the occupants, it is essential that the regularly occupied areas have access to daylight. This is important to connect the occupants with the outdoors, reinforce circadian rhythms, and reduces the use of electrical lighting thus reducing energy usage. Maintenance of circadian rhythms are controlled by exposure to daylight and the changing levels of daylight throughout the 24-hour cycle. Circadian rhythm maintenance is critical for determining of healthy sleep patterns, hormones regulation, psychological health, and overall improved human health. Data has shown that circadian rhythm disruptions in adolescent and teen-age children adversely impacts hormonal patterns and results in increased illness levels later in life, such as cancers.

For Multifamily, Option 2: Quality Views of the LEED credit specifies at least 50% of the regularly occupied spaces in each residential unit have one window including two of either 1) flora, fauna, or sky; 2) movement; and 3) objects at least 25 feet (7.5 meters) from the exterior of the window. Access to views has been shown to improve health and psychology of the occupants. Humans have an inherent affinity for nature, thus access to views offers a sense of belonging, security, and harmony.

In Step-by-Step, add subheader above Option 1. Daylight Measurement and Option 2. Quality Views: EBOM, SCHOOLS, RETAIL, DATA CENTERS, HOSPITALITY, WAREHOUSES & DISTRIBUTION CENTERS

In Step-by-Step, add new subsection, after Option 1. Daylight Measurement, step 4, with the following text:
Multifamily
Option 1. Daylight Measurement
STEP 1. PREPARE FOR MEASUREMENTS
• Determine when the measurements will be taken. Measurements may be taken anytime during the day in September, October, March, or April.
• Draw the measurement grid and the measurement nodes (usually at the center of the grid space) on a floor plan. Alternatively, tape or mark off the measurement grid on the floor of the actual space and document the grid with photos or a video.

STEP 2. PERFORM MEASUREMENTS
Use a light meter to take a daylight illuminance measurement at 30 inches (760 millimeters) above the floor (or at kitchen counter height for kitchens).
• Refer to the IESNA Reference Guide, 10th edition, Section 9.7, for more information on light meters.
• Locate each measurement node in the actual space.
• Record the measured illuminance at each node on the floor plan or in a tracking table.
• If the reading exceeds 5,000 lux, note whether blinds or shades are incorporated.
• All measurements do not need to be taken on the same day.

STEP 3. EVALUATE ILLUMINANCE COMPLIANCE
Review the measurement results and complete the calculator provided by USGBC, or similar tracking table, to determine compliance with the two separate requirements: minimum access to daylight in each living space, and adequate daylight for the building.
• Minimum access to daylight in each living space: For each residential unit, record the regularly occupied spaces with illuminance levels of at least 10 lux for at least 90% of the floor area. Confirm that all spaces comply.
• Adequate daylight for the building: For the entire building, record the regularly occupied floor area with illuminance levels between 150 lux and 5,000 lux. Also include areas with levels exceeding 5,000 lux if blinds or shades are incorporated. Confirm that more than 50% of the regularly occupied floor area complies.

In Step-by-Step Guidance, add new subsection, after Option 2. Quality Views, step 6, with the following text:
Multifamily
STEP 1. EVALUATE PROJECT SITE
Review the project’s surroundings to identify the presence of elements that meet the view quality requirements of this credit, such as parks, green roofs and walls, nearby buildings, and pedestrian and vehicle movement.

STEP 2. IDENTIFY SIGHTLINES TO EXTERIOR VIEWS
Identify the spaces with a window that includes views to at least two of the following: (1) flora, fauna, or sky; (2) movement; (3) objects at least 25 feet (7.5 meters) from the exterior of the glazing.
• For each residential unit, evaluate each regularly occupied space.
• Only include windows with a clear image of the exterior, not obstructed by frits, fibers, patterned glazing, or added tints that distort color balance (see Further Explanation, Vision Glazing).
• Movement includes such activities as people walking, cars driving on the street, and boats moving through water. Movement of plants and trees from wind does not qualify.
• Identify whether the view from the window is to an interior atrium.

STEP 3. CONFIRM COMPLIANCE
Complete the calculator provided by USGBC, or similar tracking table, to confirm that for each residential unit, at least 50% of the regularly occupied spaces have a window with a qualifying view. If the building has interior atria, confirm that no more than 30% of the qualifying views are from views to interior atria.

Add a second Required Documentation Table, for Multifamily

In Exemplary Performance, add the following:
For Multifamily, achieve both options, and:
• For daylight, achieve the adequate daylight for the building requirements for at least 75% of the regularly occupied floor area.
• For views, achieve the requirements for at least 75% of the regularly occupied spaces in each residential unit.
