1) The document presents a case study on building energy conservation and wall thermal insulation. It discusses determining the optimal thermal conductivity value of walls through measuring existing wall thickness, insulating materials, and retrofitting. 2) The methodology section outlines measuring wall thickness, determining pre-installation R, U, and K-values, adding insulating materials like EPS and air gaps, and surface finishing. 3) The conclusions recommend improving U-values through adding EPS insulation to walls, controlling future CO2 emissions, and saving energy to meet demand from excess population growth.
