| Abstract |
The objective of this research was to devise a methodology for quantifying the lighting energy conservation benefits afforded by dimming controls in daylight-responsive buildings, utilizing the ECO2 program. Initially, the influx of natural light into the designated area was quantified via RELUX simulation, allowing for the tailoring of artificial lighting levels at each location to correspond with the fluctuating density of daylight across different seasons and times of day. Through employing varying proportions of natural illumination during both clear and overcast conditions throughout the year, the artificial lighting intensity was accordingly modulated. Upon implemention of this approach, the maximum achievable lighting energy efficiency through dimming control was identified to be 58.6%. Furthermore, correction coefficients for the established ECO2 lighting intensity were determined by comparing the lighting intensities with and without the implementation of dimming control. Hence, by integrating these calibrated lighting intensities that account for dimming controls into daylighting environments, the energy-saving potential can be effectively depicted in ECO2. |
