IES Consulting provided daylight (cr 62) and thermal comfort analysis (cr 76) services toward the WELL Building Standard.
The SCENEO project, a 130,000 square-foot office building in Bezons, France, is the first building in Continental Europe to achieve a WELL Building Standard Certification at Gold level. IES Consulting provided daylight (cr 62) and thermal comfort analysis (cr 76) services toward the WELL Building Standard.
IES Consulting used RadianceIES climate based daylight modelling (CBDM) technology to model the space performance. CBDM utilises an annual simulation linking location, shading, climate data (including solar intensity and cloud cover) together with the building properties. This provides a complete overview on how the daylight performance varies throughout the year due to changes in these factors.
The analysis included performance against sDA (spatial daylight autonomy) and ASE (annual sunlight exposure).
CBDM is more detailed than a static calculation which provides only a snap shot approach. Daylighting varies throughout the year, primarily due to the solar position, so it is essential daylighting variance is properly considered toward the impact on building design.
To achieve WELL credit 62, it requires that:
The analysis performed by IES consulting showed that the sDA criteria would not be met with the design conditions at that time, however the ASE criteria was met sufficiently to comply with that part of the credit. These results equipped our client with knowledge of the changes required to fully comply with WELL credit 62.
