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

AbstractThe researcher was noticed that through his study for Iraqi residence
building for low income people, the big similarity of its architectural
design appearance. Therefore, he was selected one of that; he was
calculated its cooling load (heat leakage through glasses, walls and roof
areas) and its electrical energy con gumptions during 12 hours/day, 30
day/month for summer months. The researcher was changed the three
parameters and replication that calculation in each once:-
• Building orientation (the researcher assumed that building would be
constructs in eight orientations.
• Building materials (the researcher assumed that building would be
constructs with five different types of walls and roofs).
• Construction position (the researcher assumed the building area latitude
would be constructs with five position in Iraq).
At last ,the researcher found that , the good orientation for that selected
building is South East – North West , which it consumed minimum
energy for cooling purpose , and that energy that building value was
increased by 8% when rotated to North East –South West and became
15% with East – West and 23% with North – South orientations and also
, the researcher found that , the good orientation is the same even if
construction position variation , but the energy required for cooling
purpose is varied , maximum energy saving about 14% when the
construction position was replaced from Basra to al-moosel , and finally
, the researcher found also , the energy saving about 16.69% when
building materials were replaced from ordinary brick to thermoston brick
with thermal insulation material and is 34.3% when usage thermal
insulation material (5 cm thickness ) in roof.
