Warm humid climate was the task in this project. existing house was having 90 dollars bill every month on electricity too hot and no day lighting in ground floor existing building had an atm. So when i designed with clay block due to frontage was 2 m all other sides was having buildings close to wall to wall construction so big task to ventilate and day light the spaces. owner had 96 sqm of terrace which has to be converted into one 1bhk and 2 bhk. so choosen clay block for time lag and heat sink. it worked well and planning was done to cool the home by passive cooling Incorporated more jalli openings larger windows. white interior for well lit. budget was 19 k dollars which was even more harder for low cost energy efficient home yet i guided client not to paint or plaster spend more on aesthetics rather on basic needs. as project electricity bill is 19 dollars complete house. due to reduce in heat and electricity load caused by day light and ventilation. gf and 1 bhk was rented for revenue generation over all client was happy
