METHODOLOGY FOR EVALUATION THERMAL PERFORMANCE OF EARTH BERMING SYSTEM FOR PASSIVE BUILDING DESIGNS

Earth berming is a storage device and helps space conditioning inside building envelope, if used carefully and tact fully. The guide lines can be used for designing passive building. The thermal analysis of wall plus earth filling outside become composite structure and can be used for maintaining IEQ. The thermal analysis of earth berming composite wall become complex if it is added with passive land scapes. This work is associated with development of methodology for evaluation of thermal performance of c omposite earth berming systems. The composite materials, considered are, 1. Lawn plus lateritic soil, brick wall with plaster on either side 2. Lawn plus black cotton soil, brick wall with plaster on either side 3. Lawn plus porous soil, brick wall with plaster on either side These composite materials are further analysed for techno - economical feasibility. It is reviewed that, the composite system of l lawn plus lateral soil, external plastering, brick wall, is better suited for low cost and durable passive s olution for hot and dry climate .Design guidelines are provide for its applications to other climate zones
