ABSTRACT: The paper discuss inside illuminance of the workplace illuminance with daylight regulation by outside blinds. Daylight regulation is advantageous for more than inside illuminance regulation but also for reducing solar load from sunshine, due to this reduction it may not be necessary using cooling systems or its energy consumption is reduced to minimum. When outside blinds are used for regulation of the inside illuminance the standards requirements may not be fit. In this case, the artificial lighting is necessary to use. It is important to correctly regulate daylight and eventually supplement it with artificial lighting to set the system for minimum energy consumption to meet all standard requirements. The measurement was performed in laboratory of lighting systems for twelve inside points and one outside point, inside points represents workplaces. With outdoor illuminance daylight factor was calculated. Results indicated expected trend, reducing inside illuminance with increasing angles of blinds.

KEYWORDS: workplace illuminance, blinds, illumination measurement, simulation, daylight factor, tilt of blinds
