Table 2. Simulated metrics according to CS autonomy. Metrics: cDA (233lx, 50%) Points 276

illuminance of 233 lux for 50% of the hours available covering at least 75% of the area), it is noticeable that in 100% of the studied area the metrics were observed. Similarly, to the study of the IES LM-83 Standards, ASE meets the criteria since only 7.6% of the area exhibits illuminance higher than 1,000 lux for 250 hours. As for UDI metrics


(considered useful illuminance ranging from 233 to 2,000 lux) criteria were met up to 96% of simulation points (criterion for approval is 80%), which means that in only 4% of the ward area light and thermal discomfort may occur.

Conclusion In conclusion, the results indicate that, despite some technological limitations, the value of the computer programs are confirmed – providing useful tools to support project decisions in line with the concept of Building Information Models (BIM). DesignBuilder stands out in thermo-energetic simulations for having a use-friendly interface. In addition, NBR 15.575-1 (ABNT 2013) standards recommend the use of Energyplus as a simulation program, demonstrating reliability in the results. The study has illustrated how CS metrics and the concept of Daylight Availability (DA) could be utilised to assist with the identification of problems related to the circadian rhythm in prolonged-stay environments, such as wards. Solving these issues, whether by natural or artificial light, has the potential to benefit hospital users.
