Delos has established itself as a pioneer in creating indoor spaces that promote human health and wellness. Most notably, the company helped develop the International WELL Building Institute and its WELL Building Standard, the first rating system to focus attention on the health of the people who live or work inside a building. When it came time for Delos to upgrade its own offices, it only made sense that the firm would partner with us to build their space, officially certified as WELL Platinum in Spring 2017.

The 19,000sf space leaves no wellness stone unturned. Flexible work stations encourage movement. Lighting systems mimic circadian rhythms. Plant walls and other foliage—plus floor-to-ceiling exterior windows and an outdoor terrace—support the space’s biophilic design. A “wellness” café even provides healthy snacks for employees and visitors alike.

To get a handle on the requirements, our project team compiled the requirements for each rating system into one master checklist. A seven-page RFI form not only outlined the criteria we needed to follow as we worked with subcontractors to purchase materials, but also left a clear paper trail of each decision. Doing this upfront kept us organized and pinpointed where we needed to do some extra work.

Delos’ space is a comfortable, healthy environment for employees, as well as a test lab for the methods and outcomes the company’s work fosters. Sensors are located throughout the office to collect data on air quality, acoustics, thermal lighting, steps taken up and down the staircase and a myriad of other factors. The office also serves as the “model home” for Delos as they meet with companies about the potential of applying health and wellness principles in their own spaces.
