Following an approach by AVN-Mali and our National Coordinator Alexe Dembele, Mali's International NGO Forum (FONGIM) has approved AVn-Mali's membership of its 'Energy and Climate' panel. Read more...
This report by experts at the London office of Environmental Resources Management (ERM), based on data provided by AVN staff in Boromo, indicates that a typical NV house of 25m2 floor space makes a saving of 2.0 tonnes of CO2- equivalents (CO2e) compared to the available alternative construction methods. Since the start of the AVN ’Earth roofs in the Sahel’ programme, one can estimate total savings of over 2,500 tonnes of CO2e.

By French builder Pierre Le Signor, this is a report of a visit he undertook in 2007 to study and describe the traditional rendering and waterproofing techniques used for walls and roofs of earth buildings in Burkina Faso. In French, with many illustrations.
This exploratory study on research into the thermal and comfort properties of VN houses was initiated in 2006 by the engineer Urs Wyss with the assistance of Balima Neya in Boromo, and written up in 2007 by Hugues Sauret. The research involved daily monitoring of internal temperatures of a VN house, compared with a ’modern’ (breeze block walls, tin roof) house of comparable size, in Boromo, over a four month period: June - Sept 2007. The initial results, despite various technical problems encountered in the monitoring process, and the limited period of the study, are promising, demonstrating effectively better thermal and ’comfort’ properties for the VN house. The report is in French.
This very detailed report is a technical and cost evaluation of the Programme for the three year period 2003 - 2005, prepared by the Swiss civil engineer Urs Wyss, for the French Ministry of Foreign Affairs (Oct 2005, in French).
This is a master’s degree semester project by three students from the Ecole Polytechnique Fédérale de Lausanne (EPFL), Christelle Cocco, Raphaël Dauphin, and Karim Ganour. The study was carried out in collaboration with Urs Wyss. It reviews the materials used in VN constructions, and establishes rules and guidelines for calculating dimensions (Spring 2007, in French).
A second semester project from EPFL students, Vincent Wurtz and Mathias Malquarti, under the supervision of Dr Lestuzzi Pierino. The study uses computer modelling techniques to analyse VN constructions (Oct 2007, in French).
