Daylighting: Natural Light in Architecture

Conclusions

The results are very encouraging, and meet the requirements of the
CIBSE Guidelines.
As expected the results for the upper level are slightly higher.
Whilst measurements were not taken directly up to the glazing line, it
is expected that the figure would be higher at this point.
The comparison of the model at the street lower level with the
subsequent computer results, shows acceptable agreement; 7 per cent
average below the North lights and 4 to 12 per cent over the office
place.
