الملخص الإنجليزي

Building envelope design has a considerable impact on energy consumption.

In Kurdistan region of Iraq and especially in Erbil city there is a rapid and wide buildings construction movement that uses different materials and technologies without any considerations to energy consumption and environment pollution.

The research mainly aims to reduce the embodied and operating energy.

The secondary aim is to reduce the pollution impact of materials during preparation and building construction. First of all, the research has used a historical review to discover methods of walls and roofs designing which built by ancient people to reduce energy consumption. It also has made a primary survey to discover and compare the energy consumed by modern vernacular architecture and traditional architecture in Erbil city.

The results of a roughly primary survey have showed that the old traditional architecture consumed less energy than the modern vernacular architecture in Erbil city.

The research has reviewed the main literature about building architecture envelope design and energy consumption.

Then, it has made a comparison between time lag and insulation strategies that are used in architecture.

The research presents previous studies in the world and in Iraq in order to show the knowledge gap pertinent to the problem.

The research has used the experimental method in a case study and has prepared a model of a modern vernacular architecture to be simulated by energy plus software program to examine the thermal efficiency.

The research has two independent variables : wall design and building orientations.

The wall design includes (66) cases of different materials that should be tested.

The second variable is the orientation which includes eight directions (South, North, East, West, South East, South West, North East and North West).The research has used four dependent variables: running cost (Rx) , price of units (X), (Z) value (Z = Rx + X) and space increment.

The research used descriptive statistics to analyze resulted running cost and price of units.

The results show clearly the role of thickness of materials, air gaps and insulating material in thermal efficiency of an envelope of a building .This refers to the reduction of using extra energy as fossil fuel and reduction of air pollution at the same time.
