“…Evangellos Bacharoudis [5] and other experts through experimental and theoretical studies in the hollow insulating exterior walls by natural convection heat flow under certain role, get the hot summer areas, superior insulation properties of opaque and transparent board insulation board. And other research papers [6][7] also proved the correctness of its conclusions. Therefore, this paper is an opaque plate exterior walls.…”

Because of the relatively small number of the subtropical region building energy research, resulting in the construction of energy-saving measures in the area of building energy method is mainly imitate other regions. The building energy efficiency should be appropriate. And the crucial of the building energy efficiency in subtropical region is heat insulation processing. This paper presents the idea of a subtropical region suitable for natural ventilation insulated exterior wall structure. A new kind of suitable natural ventilation and heat insulation building structure for exterior wall in hot summer and warm winter area is proposed in this paper, which thermal properties is calculated by Maple software. And this paper demonstrates that this kind of structure is the feasibility of the structure. The result of the comparison of thermal properties of different insulating structure by using the finite difference method for unsteady heat conduction calculation presents that the insulation performance of the buildings which have the natural ventilation and heat insulation structure is better than the ones without this ventilation. In the end of paper, the authors descript the hope that this kind of structure will be further research and analysis.

This paper investigates thermal walls behavior as elements of buildings and low-consumption energy residences. The problem is formulate based on the transient and unidimensional model, and numerically solved using the finite volumes method to discretize space and the implicit formulation to discretize time. Numerical tests were realized to optimize the mesh. Three different materials, heat transfer coefficient and color incorporation were tested in each wall layer A and B. The influence of these variations in the internal wall was calculated for each case. It was found that the best material for A and B walls are plaster mortar and common brick, respectively. This is a result of the inverse correlation between thermal resistance and the heat transfer rate. For a lower temperature in the external and internal walls, the thickness ratio for the external wall was  < 0.5 and for the inner wall was  > 0.5. The best value of absorptivity was 0.156 and the external heat transfer coefficient was variated to increase heat change. With all these parameters analyzed, it was possible to decrease significantly the heat transfer to the inner space and enhance the thermal comfort.
