MBS Daylight for SketchUp
A VSC & APSH calculator that also produces a Waldram Diagram
MBS Daylight for SketchUp

The Extension requires 3D models of a proposed development and the surrounding impacted buildings; calculations can then be performed to determine the Vertical Sky Component (VSC) and the Annual Probable Sunlight Hours (APSH). The results are delivered in both graphical format, as Waldram Diagrams and as a quick visual pass/fail/nearly ‘traffic light’ system within the SketchUp programme itself.

Any modifications or cutbacks to the proposed scheme can rapidly be re-analysed.

Hours of sunlight to an amenity space can also be tested and facade analysis can be performed for all these tests. Transient shadow images can be generated for a specified date and time interval. The colour of the shadow cast will match the proposed or existing building making it easy to see the impact of a scheme.



Recommendations for light levels in new buildings and surrounding properties are provided by the Building Research Establishment (BRE) within a document called ‘Site Layout Planning for Daylight and Sunlight - A Guide to Good Practice', 2011 by P J Littlefair. Many local authorities have adopted this guide, so these recommendations provide a foundation upon which planning permission is granted, or refused, in the UK.

Whilst the software has been designed to comply with the Daylight tests as laid out in the BRE Guide, the system is fully customisable by the end user.

A full free 7 day trial ( we recommend using it on a real project) can be downloaded from our company website.

The plug-in is available from SketchUp 8 up to the present version.
