The building is located in the campus of UIB outside of Palma downtown and serves as pilot case to assess the environmental performance of the building in relation to the Mediterranean climate. Figure 1 shows the modular building designed as a single room of approx. 6 m2 with an entrance door and without windows. The total indoor space volume is 15 m3. 2.2. Cold painting solution The cold painting material selected in this analysis is an outdoor paint with a high performance as a thermal isolation and minimizing solar radiation impact. The paint is designed for application over metallic or prefabricated roofs producing an indoor temperature reduction maintaining the external roof at ambient temperature. Two layers of Quimfor Coating no7 WB where applied using a roller-based method. The Table 1 summarizes the main features of the solar paint applied reported by provider following the measurement method described in ASTM E1980:2001. 2.3. Energy savings analysis The building is equipped with an air conditioner system with solar energy capabilities to become an isolated installation from the main electric power. The air conditioner system provides an easy way to monitor the building power consumption requirements. The temperature and the electric power consumption have been monitored to observe the energy savings on the climate conditioner system during summer conditions in Mediterranean clime. The difference temperature reported during a period of time impact directly on the air-conditioner system because this temperature increment is dissipated part to the ambient and part to the internal room pushing the power consumption of cooler system. A very representative demonstration of this temperature difference is the thermography showed in figure 2. The cooler surface is oriented to South and is painted. The hotter surface is oriented to West without solar paint. The temperature maximum difference observed was about 9oC between surfaces. The differences observed between the surface temperatures are translated to power savings. Therefore, the total consumption is reduced as the working state of air conditioning is retarded, when the eco-materials and solar paint are used. This delay is translated directly amount savings because the energy consumption is reduced. The parameters summarized in Table 2 shows the benefits of the building approach.
