Research Abstract	Patterned cementitious surface conrolling sunlight reflection were designed and developed to increase heat transfer from sunlight in winter and decrease in summer. A heat transfer model for the concrete surface considering heat irradiation on the surface microstructure is proposed and compared with the experimental results. As a results the surface of the concrete, which has seasonal heat selectivity, is developed and the effects of CO2 reduction are calculated quantitatively based on degree-day methods.
