Focal Point

The WELL Building Standard™ (WELL) is the premier standard for buildings, interior spaces and communities seeking to implement, validate and measure features that support and advance human health and wellness.

 

Both the current standard, WELL v1, and WELL v2, which is in the pilot phase are available for projects seeking registration. The WELL website offers a comparison tool to evaluate both versions of WELL and determine key similarities and differences.

 

Focal Point lighting and acoustic solutions may contribute to achieving the following Features of WELL v1 or WELL v2 pilot. Read on to learn more or contact us with your specific questions.

 

WELL v1
 

 

FEATURE 54 – Circadian Lighting Design (Precondition)

 

Intent: To support circadian health by setting a minimum threshold for daytime light intensity.

 

Melanopic Light Intensity

Part 1

Work Areas

150, 200 EML

Part 2

Living Environments

50, 200 EML

Part 3

Breakrooms

250 EML

Part 4
