Daylighting Performance of Integrated Venetian Blinds with Horizontal Light Pipe System for Deep Plan High-Rise Office in Tropical Climate

A substantial amount of daylight is received by tropical countries like Malaysia. There are advantages and disadvantages to using this renewable resource in a high-rise office building. Such buildings' deep plan spaces make it difficult create uniform distribution across the space. solution for issue usage an integrated Venetian blind (VB) with horizontal light pipe (LP). Using overcast intermediate sky South orientation, seven (7) distinct types VB angle configurations were simulated Integrated Environment Solution Virtual (IESVE) evaluate how well they performed LP. The findings demonstrated that uniformity throughout room was improved integration LP systems. When compared only installed, 0o -15o angles had best performance. combination allowed shading front portion space at same time, illuminating rear results study encourage building designers utilise open-plan reduce use non-renewable energy resources.
