As case study

As case study, a row house in the old town of Ostuni was analyzed. The results of the study have shown there is no need for cooling system in the house. In the case of the winter week, instead, energy requirements for heating are higher in the case of the white external finishing layer.
Also the simulation of summer week in Bolzano shows that the cooling system is not necessary in summer (thermal inertia of the walls) and the different climate conditions in Bolzano, characterized by summer temperatures lower than those in Ostuni. For cooling there are used passive strategies and for heating it was used fireplace. The level of luminance in the street between the buildings is depends on the color of finishing layer. In the case of light color, the average value of the Daylight Factor is 49.54% with a minimum value of 36.90%, due to the height of buildings that provides shading in the urban canyon. In the case of dark color (Red Bricks), average Daylight Factor is of 37.45% and the minimum value is of 23.8%. The analysis of the external visual comfort analysis shows that the white external finishing layers, reach adequate levels of luminance comparing to the dark ones. Also the white color provides a better hygiene, inside buildings and urban environment. (Figure 10) (Fabiana Convertino, 2017)
