At least one such window is present in each room with operable windows. b. If project is equipped with heating, at least 30% of operable windows may be opened such that entirety of opening is at least 5.9 ft(1.8 m) above the finished floor (preferably as close to the ceiling as possible).5 At least one such window is present in each room with operable windows. c. Controls for window operation are positioned not more than 5.6 ft(1.7 m) above the finished floor. Option 2: Window operation Instructions for window operation are provided through signage or other communications to regular building occupants to indicate the following: a. Windows with low openings are to be used during mild and/or warm weather. b. Windows are not to be opened when mechanical cooling is in operation (not required if no mechanical cooling is present or if mechanical cooling system is configured to disengage automatically when windows are open). c. Windows with high openings (if present) are to be used in cold weather. Note: All projects are required to submit the WELL beta feature implementation feedback form for every WELL beta feature pursued during documentation review.

WELL Certification: 1 Pt | WELL Core: 2 Pt For All Spaces: Option 1: Outdoor shading The following areas (if present) are shaded for more than half of daylight hours each day by tree canopies, awnings, or other structures: a. At least 50% of pedestrian pathways and building entrances. b. At least 25% of parking spaces (if present). c. Between 25% and 75% of all plazas, seating areas and other outdoor areas of congregation. Note: All projects are required to submit the WELL beta feature implementation feedback form for every WELL beta feature pursued during documentation review. More information on WELL v2 beta features can be found at https://resources.wellcertified.com/articles/introducing-well-beta-features/. OR Option 2: Temperature modeling For pedestrian pathways and building entrances, parking spaces, and plazas, seating areas and other outdoor areas of congregation, project provides the following: a. Highest expected measure of thermal perception for each month (e.g., highest Physiologically Equivalent Temperature, highest Universal Thermal Climate Index). b. If the highest measure of thermal perception is associated with “moderate” (or more severe) heat stress, a list of countermeasures within at least two of the following categories and the expected reduction in heat stress that they provide: 1. Landscaping and greenery. 2. Manufactured shading systems (e.g., canopies). 3. Reflectance of manufactured surfaces (e.g., sidewalks, rooftops). 4. Water features (e.g., ponds, fountains). Note: All projects are required to submit the WELL beta feature implementation feedback form for every WELL beta feature pursued during documentation review. More information on WELL v2 beta features can be found at https://resources.wellcertified.com/articles/introducing-well-beta-features/. Note: Interior projects may achieve this part if the grounds of the base building meet the requirements, even if they are outside of the interior project boundary. WELL Core Guidance: Meet the requirements in the whole building.

WELL Certification: 1 Pt | WELL Core: 2 Pt For All Spaces: A computational fluid dynamic model of the building and any adjacent buildings that takes into account at least one day per season (i.e., per quarter) demonstrates the following: a. Winds are not expected to exceed 11 mph(5 m/s) for more than 5% of hours in the year in seating areas or 10% of hours on paths and parking lots.14 b. Winds are not expected to exceed 33 mph(15 m/s) on paths, parking lots or seating areas for more than 0.05% of hours in the year.14 Note: All projects are required to submit the WELL beta feature implementation feedback form for every WELL beta feature pursued during documentation review.
