The Effect Of Changing Iraqi Residence Building Orientation , Materials And It's Construction Position On Energy Consumption

Abstract

The researcher was noticed that through his study for Iraqi residencebuilding for low income people, the big similarity of its architecturaldesign appearance. Therefore, he was selected one of that; he wascalculated its cooling load (heat leakage through glasses, walls and roofareas) and its electrical energy con gumptions during 12 hours/day, 30day/month for summer months. The researcher was changed the threeparameters and replication that calculation in each once:-• Building orientation (the researcher assumed that building would beconstructs in eight orientations.• Building materials (the researcher assumed that building would beconstructs with five different types of walls and roofs).• Construction position (the researcher assumed the building area latitudewould be constructs with five position in Iraq).At last ,the researcher found that , the good orientation for that selectedbuilding is South East – North West , which it consumed minimumenergy for cooling purpose , and that energy that building value wasincreased by 8% when rotated to North East –South West and became15% with East – West and 23% with North – South orientations and also, the researcher found that , the good orientation is the same even ifconstruction position variation , but the energy required for coolingpurpose is varied , maximum energy saving about 14% when theconstruction position was replaced from Basra to al-moosel , and finally, the researcher found also , the energy saving about 16.69% whenbuilding materials were replaced from ordinary brick to thermoston brickwith thermal insulation material and is 34.3% when usage thermalinsulation material (5 cm thickness ) in roof.
