During the Building Simulation and Optimization (BSO12) held at Loughborough University, UK on September 10-11, 2012, the Best Paper Award in Modeling and Simulation was granted to an article by John Mardaljevic from DeMontfort University (who joined Loughborough University since) and Marilyne Andersen from EPFL, also co-authored by two collaborators from VELUX, Nicolas Roy and Jens Christoffersen.

The BSO12 conference was the first IBPSA-England conference, national edition of the International Building Performance Simulation Association (IBPSA) organized in partnership with Chartered Institution of Building Services Engineers (CIBSE). The award-winning article, entitled « Daylighting Metrics: Is there a relation between Useful Daylight Illuminance and Daylight Glare Probability? », raises the difficult issue of reconciling illumination objectives with visual comfort constraints, which are typically based on different quantities (horizontal versus vertical, illuminance versus luminance). The article proposes to extend the limits of horizontal illuminance calculations to glare considerations via a simplified glare metric that was recently proposed by a research group at Fraunhofer ISE in Germany, and to test its correlation with upper bounded annual (climate-based) illuminance data.
