In this article, indicators of annual energy intensity 13 residential complexes with different characteristics were evaluated and compared. These features include the type of facade, heating and cooling systems, windows, and separate or shared type gas meters are units available in the complex. Introducing selected complexes, specifications hull, heating and cooling systems as well as the energy used in the study and analysis of energy flows in the complex have been discussed. The data processing methodology for calculating the energy consumption rate index have been studied conglomerate. The indices are calculated energy intensity of buildings and structures with different properties in terms of energy intensity compared. Compare energy intensity indicators show that the use of new energy Mtalh like metal siding board (decorative panels) instead facade, windows UPVC windows instead of metal, instead of single-wall and double glass instead of heaters and boilers as well as the use of semi-centralized heating systems or room in the building's energy intensity has considerably decreased. Also, instead of using a separate gas meter gas meter joint, by influencing the behavior of the occupants of the building and create a financial incentive to reduce energy use saves natural gas consumption and decreasing energy intensity building.
