We are highly experienced in the computer modelling and analysis of sunlight, daylight and artificial lighting in both new and existing buildings. Through the use of state of the art software we are able to provide rapid assessments of your design proposals.

Sunlight and Daylight Impact Assessments are commonly required for planning applications for urban sites. Planning Authorities are keen to demonstrate due diligence in the protection of sunlight and daylight amenity for existing buildings.

We can assess development proposals to ensure that they do not infringe the BRE guidelines used by planners and provide an iterative and fast assessment of alternative massing and design solutions where required. A typical Sunlight and Daylight Assessment might include:

• Vertical sky component
• Daylight or Average Daylight Factor
• Sunpath and shadow analysis
• Alteration to no-sky line
• Probable Sunlight Hours Calculations

We can also provide design input where specific internal daylighting conditions are required. We can model complex and innovative daylighting systems including sun-pipes of any scale and relate specific daylight/lighting design proposals to predicted energy consumption or savings.

We can also complete the daylighting calculations for EcoHomes assessments.
