AbstractUsing of double envelopment is one of the passive designs processor’s, Which contributed to increase energy efficiency by get same human comfort with less energy consumption in for air conditioning in building, In this investigate Was simulation the effect the effect of using double envelopment by select Existing building at same dimensions of all façade by building energy simulation program (Ecotect) based on hourly weather data of Kirkuk city, after conducting the tests was to reach the greatest savings of HVAC annual loat at rate (9.764%) when using the double envelopment of total savings optimal for situations that have been reached through the use of double walls which has achieved a rate of savings values (6.822%) were the western facade best interfaces achieved savings rate (2.822%) and contributed to the use of ground dead with a ventilated gap East / Western and when using the false ceiling below the main ceiling rates savings (1.444 and 1.44)%, respectively for the annual loads of air-conditioning.
