Abstract

Energy efficiency strategies based on daylight-artificial light integrated schemes have been augmented exponentially in recent years. Taking into account the dynamics to be considered for the control and the dependence of natural and occupancy factors, it is better to have a test workbench prior to setting up the final control scheme. This work describes a climate responsive test workbench for the real time testing of the control of luminaires and window blinds in daylight-artificial light integrated scheme. The established climate model based control scheme suitable for the optimum integration of visual comfort, thermal comfort, and energy consumption can be tested for any ecological conditions. The input irradiance from BF5 sensor, internal temperature from Micro DAQ logger, occupancy and photo sensor associated with the luminaire provide input data for the test workbench. A fuzzy logic based motorized window blind controller and a look-up table based dimming of LED luminaires are used to set the required illuminance with reduced load on HVAC (Heating, Ventilation, and Air Conditioning) system. The anticipated synergetic effects of the test workbench have been validated using real time climate data. The test work bench is established on LabVIEW platform and developed standalone system using myRIO
