Daylight Calculations

Improve the quality of life in your building and reduce the need for energy to light the building through good daylight.

Daylight calculations are required for the Code for Sustainable Homes and BREEAM Assessments. Energy Rating Services also offer this service independently of these schemes.

The calculation works by ascertaining the daylight factor. This is a ratio between the luminance (from daylight ) at a specific point on the plane within a room, expressed a percentage of the luminance received on an outdoor unobstructed horizontal plane. This calculation is based on an assumed overcast sky.

To complete your daylight calculations, Energy Rating Services will need some information from you. This includes site plans, room dimensions, position and dimension of windows and other glazed areas, external building and other potential obstruction.

Call us on 01865 378885 or email us today if you require advice for your daylight calculations requirements or would like us to quote for this work. We will always provide tailored, competitive estimates promptly upon request.
