The concern for Global Warming and environmental degradation is increasing day by day. Amongst all developmental activities housing and infrastructure development are considered as major contributors of environmental degradation. One of the oldest building materials still in use in building industry is burnt clay brick. The brick masonry is extensively used in building construction where good clay is available for brick making. The process of manufacturing bricks has significant contribution in environmental degradation. For example, one million square feet of residential built up space in R.C.C.frame structure requires about ten million numbers of country bricks which shall cause to emit about 9,200 MT of CO2 and consume 40,460 m3 of top soil in the process of manufacturing them. The figures will be much higher for traditional buildings with load bearing structures. With an objective to curtail the emission of CO2 and restrict exploitation of top soil in building industry the present author has recently developed a new construction technique and termed as Eco-pan Building System. This system introduces a pair of prefabricated concrete modular units, A-1 and A-2, with nominal wire reinforcement. When laid in a parallel layers in a course they form a 200 mm thick cellular wall panel. The cellular cores can be filled with any light weight material, even with waste plastics. The purpose of filling the cores is to minimize the entrapped air. The light weight plastic in-filled wall panels add to the thermal insulation property of the panel. This system saves about 68 % of CO2 which otherwise would have caused to generate if conventional brick masonry was used. The author has implemented the system in an experimental prototype to study its technical feasibility, economical viability, and also the behavioral performance of the experimental unit. This discourse describes the new building system and its application in buildings with r.c.c. frame structure.
