Sajan's Low-Cost House

This document summarizes a conference on green homes that discussed the eco-friendly building materials and techniques used in the residence of Ar. PB Sajan and Ar. Shailaja Nair. The residence was built on a sloping hillside site using locally sourced materials like mud, bamboo, coconut trees, and reused materials. It details the treatment and use of these natural materials for the foundations, walls, floors, beams, and other structural elements. Tables are provided comparing the fuel savings from using local materials versus transported alternatives and calculating the total energy saved.
