09+Daylighting+Design+Performance



I found the average daylighting factor of one bay to be about 0.057 or 5.7% and the minimum daylighting factor is 0.0285% or 2.85%

According to Table 14.2 (MEEB Page 601) the average recommended daylighting factor that my room falls into is Difficult, prolonged tasks such as drafting, proof reading and fine inspection. This probably isn't a good idea for my restaurant or retail spaces. (Gallery utilizes panels in front of the glazing to shield the gallery of memorabilia) Knowing this, the glazing area of my project probably needs to be rethought in order to make the interior space more comfortable for the occupants.

The day light ratio of my building is 0.5 and according to MEEB the minimum daylight factor in any portion of a space, which relates to contrast ratios, should be no less than 30%. The minimum daylight factor in any portion of a space should not drop below 0.5%, which is sufficient for circulation.
