adjust conditions of the space itself. While adaptable spaces have the potential to benefit all occupants, sensory customization opportunities are particularly important for neurodivergent individuals — approximately 15–20% of the population — who may experience heightened sensitivities to environmental factors or stimuli like noise, light, and textures. [172173]

Rating system requirements are flexible to encourage highly specific design strategies. Projects must demonstrate optionality between zones or flexibility through personal comfort options for categories outlined in Table 4.

Table 4. Optionality or flexibility strategies

CategoryExamples
Thermal environmentPersonal control systems, warm or cool enclaves, radiant heating or
cooling, transitional spaces that act as buffer zones between indoor and
outdoor areas, or spaces with varying sun and shade exposure.
Sound environmentCombining active, high-sensory collaboration zones with quieter areas
featuring sound masking, white noise, nature sounds, or acoustic alcoves
for focused work, which aligns with the requirements under Option 4.
Sound Environment.
Lighting environmentCombination of task lighting, dimmable lighting systems, circadian lighting
that mimics natural daylight cycles in intensity and color temperature,
zoned lighting controls, natural light zones, or gradual transition lighting
designed to change in intensity to help eyes adjust.

Project specific strategies that do not fit within the three categories, but meet the intent of Option 2, to create diverse sensory spaces, may be submitted for compliance. This may include spatial character, degree of stimulation, or other strategies to enable people to manage their own sensory needs. [174]

QUIET ZONES

Quiet zones are required for all projects pursuing this option. Quiet zones are crucial for neurologically inclusive spaces because many neurodivergent individuals, including people with autism, experience hypersensitivity, or sensory processing differences that make them more sensitive to environmental stimuli, particularly sound. For these individuals, everyday sounds that some individuals might easily filter out — like HVAC systems, conversations, or equipment noise — can trigger sensory overload, leading to increased stress, decreased focus, and
