Dear Miss Rana Kumari Thank you very much for this wonderful lecture in UGR Do you have Lecture like this but to evaluate the glare probability DGP for non direct sun. Yours sincerely, Prof. Elgendy
i dont get why the aperture of the 200mm UGR is lower than the 130mm as the contrast [luminance to background] is higher [created by the 200mm aperture luminance] compared to the 130mm...as i know the higher the contrast the higher the UGR, which comparison between 2nd and 3rd case makes sense - lower wall reflectance creates higher contrast..
First of all appreciate you watch till end :), Yes thats the whole point of the video is, We usually miss to see the aspect relative brightness at aperture as I took constant intensity in both cases of 130mm and 200mm, hence intensity w.r.t the aperture have greater impact., which mostly be neglected by many planners who are using photometrics for calculation instead of plugins the importing luminaire size have impact in UGR results.
Hi Riya, both measurements are two different methods of measuring brightness from observer's point UGR(interior) - in the view direction (1 direction in grid form) and GR (exterior and few interiors with flood light arrangements)- 360 deg measurement from the observer point. Will sure find time to ellaborate this

That was a great high quality video.
Great Design, Great order of info and Great examples !
thank you for sharing.. sana may matutunan din ako sa sini shared ninyo
Knowledgeable video clip n thank you for detailed explanation
Thank you Ratna nice explanation of ugr
Awesome video and thanks for the great explanation. Can you please do a video for an outdoor area / path lighting for our learing and thanks.

@@RatnaKumari thank you for the explanation, helps alot 👍
can u please make an video for Diff between UGR and GR
