Buildings and communities that help people thrive – A look at the WELL standard

2019-04-02 01:01 Blog


The WELL Building Standard 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.

WELL Building Standard

WELL is grounded in a body of medical research that explores the connection between the buildings where we spend more than 90 percent of our time, and the health and wellness of its occupants. WELL Certified™ spaces and WELL Compliant™ core and shell developments can help create a built environment that improves the nutrition, fitness, mood, and sleep patterns.

Within the Light concept, feature requirements provide illumination guidelines that aim to minimize disruption to the body’s circadian system, enhance productivity, support good sleep quality and provide appropriate visual acuity where needed. Key terms include ambient lighting, illuminance (lux), visible transmittance (VT), equivalent melanopic lux (EML), glazing, color rendering index (CRI), correlated color temperature (CCT), light reflectance values (LRV), spatial daylight autonomy (sDA) and annual sunlight exposure (aSE).

The circadian rhythm

The circadian rhythm is fundamental to the health and well-being in the long term. Our biological clock requires exposure to darkness at night and the clear blue light during daytime, especially in the morning. This should be done in a rhythm of 24 hours otherwise; the clock starts to go out of tune. Disruptions in circadian rhythms leads to direct health problems in the long term and also increased risks of accidents.

Examples of WELL certified buildings

An example of a WELL project is Castellum’s Eminent property in Malmö is the first WELL-registered office building in the Nordic countries. Interest in Eminent has been massive. Eminent’s approx. 10,000 square metres are distributed over seven floors. The building contains a bistro, a gym, common conference facilities and coworking features. Eminent also has a common roof terrace with a kitchen garden for the bistro as well as outdoor workplaces.


Another example is the Citi Tower at One Bay East with its first WELL Certification in Hong Kong. The project also achieved LEED Platinum Certification, the first RESET Certification in Hong Kong, the AIA International Region Design Awards 2017 – Honor Award for Interior Architecture and the RICS “Sustainability Achievement of the Year” Award in 2016 and 2018. This is the world’s largest WELL Certified project for New and Existing Interiors. The project includes 38 separate business units and provides a home base for 3,000 staff members, formerly spread over five leased buildings, now brought together in a single multistory headquarters.

Spreading natural sunlight in the building

Via the Parans system with thin, flexible fiber optic cables you can get daylight far from windows and deep into the building where the sunlight from windows cannot reach. With the Parans system you are also able to balance the light dynamic in the room with light from the windows. As common as it is to have windows along the facade and that way bring in the natural light, as common it could be to have daylight via a Parans system deeper in into the building.
