The construction of environmentally friendly houses can reduce building costs by nearly twenty-seven percent, it was revealed at a workshop on environmentally friendly housing technologies yesterday.
Organized to commemorate Environment day by the Sri Lanka Association for the Advancement of Science (SLAAS) and Practical Action South Asian Programme (ITDG), the Rat Trap Bond method of building walls and the Filler Slab concrete roofing method were said to cut down on costs.
“With the Rat Trap Bond method you can get a slightly better saving on bricks with not the usual amount being used,” said Priyanth Yaggahahewage of Practical Action adding that 35 percent of the usual cost can be reduced by this method.
Furthermore, even though with the Filler Slab method saving is less proportionate to the walls, it would contribute to lessening unwanted concrete and metal as well as reducing the weight of the slab.
Around 125 houses have already been built in the East and the South while over 300 masons have been trained in the construction technology countrywide.
