the lighting issue was pretty annoying. using the simple guides that are out there, BS8206-2008 states daylight factors that we should adhire to, stating them in percentages not lumins which he used. second, its a very obvious trick to express how dark a room is by painting it black, so why not use black backed card with cut outs to really absorb any light that would pass in.

having recently looked into this my self, i changed grey deep window frames with white, and had a factor increase of 0.1-0.4 on average (note the guide requires 2.0 for kitchen areas for norm referencing here). so when he used black backed card windows i felt very disapointed..... if your going to try to identify problems please please don't knowingly distort the outcomes by doing things like this... and if he didn;'t know what he was doing, shame on c4 for allowing this blatent bias.

this of course is not detracting from the issue he was making, but he should have looked at the regulations we have in place and asked if they were suitable.

we should also be very aware, large windows mean greater energy loss. smaller openings are infact a much more sustainable approach.
