In this work we make a comparative study of the energy behaviour in different building types. We analyze three cases of office buildings and three residential buildings, and compare them with a previous sample. We seek to find correlations or differences in behavior in terms of potential energy losses and gains, and UL values compared with Argentinian Standards to verify the degree of efficiency. In terms of methodology, we have used the "Energo-CAD" method, based on steady-state balances. We conclude that the indicators used are clear to energetically "grade" buildings and to facilitate comparisons. In turn, smaller buildings are relatively less energy efficient than larger ones. At the same time it is noteworthy the growth of energy inefficiency over the years. Finally it is noted that none of the cases analyzed meets the National Standards.
