**9. Conclusions**

This chapter shows a thermal load quantities based on physical values for a typical central Mexico location. The values for the home areas are common in the actual sizes for mediumprized houses for Temixco location. A conclusion for this scenario is that the mediumprized houses must have 4.2 kN/m2 in weight capacity for a secure installation of solar roof facilities.

**Author details**

There are two aqueous solutions candidates to operate solar air-conditioning for roof applications: aqueous lithium bromide and aqueous hydroxides. Based on the working pair selection, the size for the heat exchanger must be defined by following the given methodology.

The solar devices are selected as function of the temperature and final use. These temperature values are higher than 90°C. The entire system (heat exchanger and solar devices) was evaluated just in operation phase and compared with a conventional air-conditioning system for 3.52 kW. The life cycle assessment concluded that in construction phase, the solar system is twice the emission in CO2 eq, but in operation phase, the CO2 eq is just 5.37% compared with the electrical device.
