Abstract:

The Pradhan Mantri Awaas Yojana-Gramin (PMAY-G) has delivered pucca rural housing at an unprecedented scale, but almost entirely in burnt brick and cement. The resulting dwellings overheat through the summer months and abandon the climatic intelligence of the vernacular Ekra house, whose woven bamboo-lattice walls have long provided passive comfort in the same climate. This thesis investigates whether a prefabricated bamboo-Ekra sandwich wall panel can reconcile the thermal performance of vernacular walling with the durability and permanence that the scheme and its beneficiaries rightly expect. The proposed 95 mm panel consists of two 10 mm bamboo-Ekra skins enclosing a 47 mm core of loose rice husk, rice-husk-stabilised mud, or an air cavity, finished with mud plaster internally and cement plaster on the weather face.

The investigation proceeds along five linked strands: a focused literature review; a pilot household survey of thirty-two respondents in two Maharashtra villages, including Katri in Nandurbar district; a hot-box-type field experiment comparing the three wall cores under three roof types; the architectural design of an incrementally expandable PMAY-G house derived from the survey findings; and a whole-building performance simulation of the proposed design under the Nandurbar climate, carried out in the Rhino–Grasshopper environment using the Honeybee and Ladybug toolchain.

The field experiment identified the roof, rather than the wall, as the first-order determinant of indoor temperature: a metal roof raised the interior peak by approximately 4 °C, whereas the three cores differed by only 1–2 °C among themselves. Of the cores, the rice-husk-stabilised mud panel exhibited the strongest thermal damping and the longest time lag, matching a manufactured mineral-wool reference using only a local agricultural by-product. The survey established that households assess walls by appearance but decide by durability and cost, and would accept the panel when presented with a plastered, pucca-equivalent finish and credible assurances on longevity. In simulation, the proposed house maintained an annual mean operative temperature near 28 °C in the habitable rooms, held about three-quarters of all hours within the adaptive comfort band under natural ventilation alone (rising to nearly 88 per cent with ceiling fans), returned an energy-use intensity of approximately 27 kWh/m²·yr, and achieved a net-positive annual electricity balance of roughly 20 per cent with a modest rooftop photovoltaic array. The findings collectively support a future PMAY-G house that is vernacular in its material logic, passive in its environmental strategy, and near-self-sufficient in energy.
