The main objective of this paper by Er.Deepak Bansal ad Ar.Poonja Nandy is to study the embodied energy values of walling materials used for cost effective houses up to 50 sq.m. The most important criteria for judging the energy efficiency of this housing typology has to fixed- whether Embodied energy or Maintenance/ Operational Energy.
