Abstract

The study made in some sites of the Analamanga Region, which are the Fokontany of Mandroseza, Ampanefy, Isaingy, Antalata and Malaho, shows the deterioration of the physico-chemical quality of the water of well. Elements that can cause illnesses for the beneficiaries are detected. The result is marked firstly by the acidity of the well water in all the Fokontany studied, secondly, by the rise in the rates of ammonium and organic matter in the wells which are located in the vicinity of several houses and those of nitrites in samples from wells located in the slums, near fields and rice paddies. Finally, for the Fokontany of Isaingy which is characterized by a very high number of hearths compared to other Fokontany, the waters of the wells are turbid and contain high levels of organic matter, total iron and nitrites.

Abstract

This study aims to provide any assistance in the design of a green thermal comfort solution that is aware of the current climate change and considers sustainable development. This concept is helpful to the environment and offers a possibility of popular use. The process results are reproducible to a maximum of eventuality in the thermal building field, but in this article, we discussed the cases of Malagasy thatched cottage with envelope in mud and roof in thatch and the case of an ordinary house of the popular Malagasy mass, with fired clay brick envelope, cement coating, galvanized corrugated iron roof. The approach is as follows: locate the study area, analyze the scenarios of ecological thermal solutions, carry out the heat balances according to the scenarios, and classify the optimal solution. To do this, METEONORM is used for geographical location, the heat balance is carried out using the THERMEXCEL tool, and the multi-criteria analysis is made by the PROMETHEE tool in the educational version.
