Arup and the WaveGo- Health and Wellness in Buildings

Arup, a global engineering and consulting firm, requires accurate, easy to use tools to monitor lighting for its customers interested in constructing and maintaining healthy building environments.

WaveGo is a simple, smartphone-connected device for characterizing light. When paired with its smartphone application, the handheld device can measure lighting characteristics important to human-centric lighting, such as melanopic lux, blue light exposure and absolute irradiance.



Employee well-being is a hot topic. Workplace wellness initiatives are linked to increased productivity and decreased medical absences. Wellness characteristics are frequently cited as a company selling point, helping employers in their efforts to attract top talent.

With increased corporate interest in wellness, the International WELL Building Institute (IWBI) has developed lighting guidelines as part of its WELL Building Standard (WELL, for short). They aim to quantify and standardize one aspect of employee wellness in the workplace. WELL ensures lighting has been designed to aid circadian rhythms, which regulate sleep, contributing to increased wellness for building occupants.

As a global engineering and consulting firm, Arup frequently trials lighting innovations in their own workspace before using them in design work and recommending them to clients. This includes measuring lighting parameters that meet WELL.

Equivalent Melanopic Lux (EML) is the key metric of the circadian lighting design section of WELL. Currently, EML measurement requires time-consuming and complicated calculations. These complex calculations, coupled with the laborious nature of commissioning individual lights (a type of quality assurance process), makes assessing the EML of lighting especially cumbersome.

The Arup office in Chicago, Ill., turned to Wave Illumination to measure the EML of newly installed lights in its office, as our WaveGo equipment captures data quickly and requires minimal background technical knowledge to operate. Additional support is available via WaveCloud, an integrated cloud storage platform.

The new lights in question aim to meet the WELL target EML level. Arup now have a quick commissioning tool, usable not only for this project, but for future lighting tests too. Within 10 minutes, we had assessed 10 lights for EML throughout Arup’s open office space.

Why is the WaveGo the difference?

Currently, there are limited light measurement solutions on the market accessible to a wide range of user types. Few technologies allow engineering firms like Arup to quickly take measurements of their lighting and automatically record the results.

With a WaveGo unit of their own, Arup’s users can assess any luminaire for key lighting metrics, conforming to WELL. This will aid Arup’s internal product assessments and demonstrations for visiting clients in the office and in the field.
