Daylighting and Thermal Performance of Thai Modern Façade Wall

This paper reports the experimental investigation of Thai Modern Façade Wall (TMF) and Thai Modern Façade Wall with Fin (TMF-WF); the TMF composed of two layers, the outer layer is different materials (fiber glass cement and aluminum plates) and the inner layer is clear glass. The TMF-WF has three layers; both layers are same the TMF and the third layer is aluminum fin installed front of the outer layer. They are opening air vents on the bottom (room side) and the top (ambient side). The size of opening was 0.14 x 0.60 m2. TMF and TMF-WF were investigated the performance and compared to the Double Glass Window (DGW). Experimental results were showed the average indoor illuminance of TMF-WF and TMF was higher than the standard illuminance by about 1,300 lux and 2,000 lux, respectively. The air flow rate and number of air change by about 0.005- 0.013 m3/s (18-46.8 m3/hr) and 2-12 ACH, respectively.
