Daylight – Shading devices - KBCN1815

If any of the assessed spaces are expected to contain moveable shading device (such as blinds), then a dynamic modelling of their use should be included in the calculation for options 2 and 3, consideration should be made to the shading guidance in EN 17037 or IES LM-83-23, respectively. Option 1 does not have to include dynamic modelling of moveable shading devices. This will be updated in the next re-issue of the new construction version 7 schemes.

Glare control – Modelling - KBCN1800

The ‘Glare control’ criteria do not require a specific methodology to be used to identify areas at risk of glare, and in most situations, a simple solar path analysis would be suitable. Alternatively, detailed hourly modelling methods, such as DGP and ASE, may be more appropriate. However, in either case, compliance cannot be assumed. Regardless of the methodology used, the modelling must be supported by robust reporting to demonstrate that each aspect of the criteria has been met.
