We take your proposal (in CAD or 3D form), and set out a scope of tests appropriate to the situation: own project (self) tests, neighbour impact tests or both, and whether  for daylight, sunlight/ overshadowing or both. From there we develop the analysis regime to cover daylight (spatial daylight autonomy/ daylight availability for  self tests and VSC for neighbours), sunlight exposure (1.5 hours on  March 21 for self and  APSH for neighbour tests) and amenity sunlight (to outdoor areas) for both self and neighbour impacts. We can also help you achieve daylight credits in LEED and HPI. The analysis  is specific to your location whether it's Cork, Dublin or the rest of Ireland. 

​

Analysis results are then set out in an authoritative report for your planning submission, with  individual and  project wide results across the different metrics illustrated and interpreted. Potential impacts  are presented clearly, and any remaining challenges are contextualised wih mitigation or compensatory actions set out convincingly so as to  balance daylight and sunlight performance against competing goals (density, mixed use, scale, heritage) as the guidance allows.    

Our modelling and analysis are of course grounded in the methodologies set out in  the recently updated BRE 209 2022-Site Layout Planning for Daylight and Sunlight,  BS EN 17037, the stricter EN 17037, and other local and national standards, all presented in a professional report suitable for submission to planning authorities.
