Effect of using internal packaging materials for new building walls on heating load

Abstract EN

Experimental and theoretical investigation of three types of internal packaging materials(PVC, MDF, Gypsum board) for the residential building was carried out in the present work, to reduce heating load in winter.

Experiments were carried out at the university of Wasit (Al-Kut city, late 32.5N), winter season by building small room from sandwich panel.

The room's dimensions were 2m width, 2m length and 2.4m height.On the south wall, made two slots, the slot dimensions are 0.3m width and 1m height.

Two types of walls built in the two slots.

The first wall was built from common bricks.

The second wall was built from bricks covered with packaging material.

The radiant time series (RTS) method was used for calculating the experimental heat losses through the walls.ESP-R used to calculate the theoretical result.

The results of the experimental work show that.

The maximum values of percentage energy saving as follows: Internal packaging materials; 22.87% MDF, 20.48% PVC and 16.45% Gypsum board
