The house used for this simulation was a 70 m2 apartment with a concrete ceiling, a mosaic-ceramic floor and 16 cm-thick brick walls. The orientation was north to south, with four 3-mm thick single-pane soda-lime glass windows facing north and four facing south. The ratio of window to wall area was 20%. The simulation process compared the energy consumption for the building when Mexican standard recommended data were used against the energy consumption when the experimental data were used. The apartment in both cases was considered to be inhabited by 5 persons. The simulation also considered the use of heating by electrical resistances, as well as air-conditioning equipment with a direct expansion cycle and a COP of 2.6. The geographic locations used in this simulation were: Mexico city, Chihuahua city, located in the north-central part of Mexico, Mexicali city, located in the northwest of Mexico, and Merida city, located in the southeast of Mexico, all of them with very different weather conditions. Table 2 shows the annual average and extreme values of temperature, as well as the average relative humidity (Ministry of Livestock and Hydraulic Resources, 1981) and global horizontal solar irradiation (Almanza et al., 1992), for each locality. The interval of comfort temperature was taken as 22-25.5°C.
