Daylighting Street Level Offices in City Buildings with Light Deflecting Panels
The utilisation of skylight in rooms at the lower levels of narrow streets can be greatly improved by deflecting skylight into the rooms with laser cut light deflecting panels. This paper develops the theory of skylight deflection by laser cut panels for both street and atrium style facade configurations and takes into account shading of deflecting panels by higher panels. The results are presented as vertical illuminance through the window as a function of tilt angle of the panel. Optimum configurations of the deflecting panels can be obtained from these results. The predicted vertical illuminance is normalised to zenith sky luminance so as to make the results applicable to overcast sky conditions at any latitude and time. Preliminary measurements in model buildings confirm enhancement in the utilisation of skylight by factors up to ten times and provide information on the distribution of deflected daylight in adjoining rooms and on the utilisation of light reflected from the facades—aspects which are not included in the theoretical development.
