ABSTRACT

The paper discusses the influences of the mass of components on temperature distribution in a model house built with PPECB (Paper Pulp and Earth Composite Brick) bricks. CFD Code, CFX-4.3, has been adopted for the calculation. Governing equations for mass, momentum and heat transfer were solved for the transient situation. The momentum equation was closed with κ-ε turbulence model. The results show that the thermal conductivity of the ground floor is a very important factor in adjustment of the microclimate in the house. Partitions can contribute to moderation of the microclimate in the house. However, a raised-timber floor is not so much thermally effective. These quantitative results for the effects of the structural components on temperature distribution are expected to be useful to guide the designers and engineers in the design and construction to achieve a more equable microclimate in housing with PPECB bricks.
