UNIT 1
Passive Zone Glazing Visible Transmittance
The living unit 1 represents the single bedroom with kitchenette (Fig. 4.3.1.), that locates in the West Block, which has best daylight potential. Due to the minimum obstructions the area of the windows was estimated as only 2 sq/m.. The window to floor ratio estimates 22% that is very usual for local housing and match the typical student accommodation bedroom. Compact floor layout allow to keep the area of the window 45% smaller comparing to an average (Appendix C. Case Study) in the case study. It reduces solar heat gains in the summer as well as heat loss in the winter. To compensate the minimized area inside bedrooms, the extensive communal program provided on each floor. The simulation (Appendix A. Software Simulations) shows that within the passive zone the average daylight factor estimates 3.8% and the 83% of the area receive the required daylight what guarantee good quality of the daylight on the surface of the working desk and kitchenette. The window in the bathroom allow it to be daylited with an average Daylight Factor of 1.8% that allow to use it use during the most of the daytime without addition artificial lighting. 46
