Modeling Applications - an overview of our three main types of projects:

Shadow Impact Assessments - related to proposed development and building projects - we have represented proponents as well as objectors.  Project types range from proposed house additions to 75-storey condo developments.

Solar Access Studies - related to passive solar energy, architectural daylighting, and pedestrian comfort.

Collision & Crime Scene Reconstruction - related to the investigation and reconstruction of collisions of all kinds (e.g. involving pedestrians, cars, trucks, buses, trains, aircraft and watercraft) where sun glare or blinding is suspected to have been a contributing factor, and crime scene reconstruction where there are issues related to visibility / ambient lighting / suspect identification.  We also provide forensic shadow analyses of photos and videos to determine and/or confirm the date and time they were taken.  Our analyses assist in establishing timelines and proving/disproving witness statements in criminal, civil and collision investigations.
