Hygrothermal properties of building materials, climatic conditions and energy performance are interrelated and have to be considered simultaneously as part of an optimised building design. In this paper, a new approach to evaluate the energy consumption of residential buildings in Morocco is presented. This approach is based on the effect of coupled heat and moisture transfer in typical residential buildings and on their responses to the varied climatic conditions encountered in the country. This approach allows us to evaluate with better accuracy the response of building energy performance and the indoor comfort of building occupants. Annual energy consumption, cooling and heating energy requirements were estimated considering the six climatic zones of Morocco. Based on the results, terms related to coupled heat and moisture transfer can effectively correct the existing energy consumption calculations of the six zones of Morocco, which currently do not consider energy consumption due to coupled heat and moisture transfer.

Properties Of Soil

Abstract Ground-heat transfer is tightly coupled with soil-moisture transfer. The coupling is threefold: heat is transferred by thermal conduction and by moisture transfer; the thermal properties of soil are strong functions of the moisture content; and moisture phase change includes latent heat effects and changes in thermal and hydraulic properties. A heat and moisture transfer model was developed to study the ground-coupled heat and moisture transfer from buildings. The model also includes detailed considerations of the atmospheric boundary conditions, including precipitation. Solutions for the soil temperature distribution are obtained using a finite element procedure. The model compared well with the seasonal variation of measured ground temperatures.

The Heat Transfer Coefficient

This paper investigated the effect of different initial moisture contents on the characteristics of coupled heat and moisture transfer of a reinforced concrete-EPS thermal insulation composite wall in Harbin. The change of the moisture content with time and the change of the heat transfer coefficient with time of the reinforced concrete-EPS thermal insulation composite wall at different initial moisture contents in Harbin were numerically simulated. The relative humidity and the quantity of condensed water in the air layer of the reinforced concrete-EPS thermal insulation composite wall were also calculated. The paper provides a scientific proof for the influence of the process of construction of a reinforced concrete-EPS thermal insulation composite wall on the energy-saving of buildings.
