3. RESULTS AND ANALYSIS
3.1 Illuminance Evaluations
Hundreds of parametric simulations were done comprising all four orientations, but the most relevant data for the South-facing prototype is presented in this paper. Quantitative results are summarized in Figs. 3, 4 and 5. They are used to characterize how the devices perform during different seasons and also hour by hour on representative dates.
Fig. 3 is a histogram comparing the illuminance performance for all three systems year round at different depths of the room (200, 600 and 1200 cm). The basecase is detailed without blinds at all times and blinds operating as described in the previous section. To gauge their operation, absolute illuminance limits were set in the histogram [12]. The minimum was set at 300 lx, and the maximum at 4,000 lx.
