Research of Artificial sites green roof for energy-saving efficiency in Taiwan Taichung

In this study, set the empirical plane pilot area planting the groove (long 425cm x width 300cm x Height 20cm) in the Taichung City residential area on the second floor roof, planting the groove bottom-up sequence laying frame high-rise, water proof layer, drainage layer,filter layer (non-woven, water-pottery-stone), the medium layer and planting of layer, planting the groove around the hollow brick interval income side to lighten the load. Noon hours exposed roof temperature of 25.49-37.56 degrees C, green roofs surface only at 16.45-24.69 degrees C, 17.74-24.79 degrees C indoor temperature on the second floor, effectively prevent the roof surface temperature rise, and thus reduce the interior roof of the second temperature7.75-12.77 degrees C. Building green roofs to cooling, mainly to reduce the building temperature, reducing air conditioning electricity consumption, accomplish cooling and energy-saving benefits.Compare different annual electricity consumption in the same period, extensive green roof to total electricity consumption of 860 K.Watts/hours, exposed roof to total electricity consumption in 1767 K.Watts/hours, 48.67% of the electricity consumption savings, to achieve energy efficiency.
