The WELL Building StandardTM was founded on seven concepts of wellbeing in the built environment. One of these concepts is lighting, which WELL version 1 organizes into 13 lighting “features.” Note: The WELL version 2 pilot is built on 10 concepts with features being evaluated as pre-conditions or optimizations.
Ketra’s high degree of tunability and control along with its pre-programmed Natural Light show offered a solution that tightly aligned with WELL’s lighting requirements. Caitlin Toczko, along with the Delos project team selected Ketra lighting because:
Uniformity of color across Ketra’s individual diodes produces extremely high quality light output
Control system and individual addressability of each Ketra lamp fulfills a WELL feature requiring small control zones
Lighting designers can tune Ketra's spectral power distribution (SPD) and correlated color temperature (CCT) to meet WELL's EML requirement without increasing light intensity and power usage that could jeopardize LEED requirements
Post-installation adjustments for specific CCTs within distinct zones and rooms can be easily addressed from Ketra's mobile app to its wireless lighting system
To meet WELL’s lighting feature requirements, the fixture layout was meticulously plotted to ensure luminaires were mounted in the best spots for employee workstations. In the open work area, daylight from surrounding windows fills the space while Ketra lamps and linear pendants mimic sunlight to extend natural light to every corner. Lamps are set to an astronomical timeclock to shift dynamically throughout the day, so employees feel more connected to the outdoors, and sensors are installed throughout the space so that indoor lighting dims in response to daylight. In meeting and training rooms, employees can override the natural show and personalize the light for collaboration, team presentations, or focused task work.
