Reduction of heat transfer through walls in building by using local natural insulation in Iraq

الملخص EN

The energy saving is very important in the practical application engineering.

This research studies on this subject in the field of air conditioning.

A numerical program has been developed to obtain the thermal response of different walls to energy sources (solar and ambient temperature) in summer of Iraq.

Anew local natural insulation is used to reduce heat gain to air-conditioned space.

This work proposed to used local natural insulation from palm fiber, local cane mat and local plastic mat to save energy required to condition a space.

A finite element solution for heat flow through wall is used with suitable iteration solution where boundary conditions are varying due to solar radiation and environment thermal load.

The result-in saving of about 50 % of energy that may pass through walls when used mat cane local compared to the mat plastic local and palm fiber.
