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.

View out – communal lounges, living rooms and bedrooms - KBCN1828

The default criteria for these space types requires relevant positions to be within 5m of an opening. Where larger spaces are ≥ 50m2 NIA, the standard view out criteria for the relevant scheme is applied instead. The 5m rule is intended for small scale domestic spaces where proximity to a view out is beneficial. This KBCN recognises that for larger relevant spaces in Residential, Multi-Residential and Residential Institution asset types, a scalable approach in line with commercial buildings is more appropriate.
