Energy Efficient Construction Using Carbon Neutral Blocks

Abstract:

The present paper highlights the adoption of carbon neutral building blocks in various structural elements of building to reduce GHG emissions. The Soil-Cement Fly Ash (SCF) blocks developed can be used in masonry, lintels and slab panels to reduce energy to a greater extent. While the energy content of the block developed is zero (carbon neutral), the energy content of the masonry wall can be reduced from 100% for a conventional masonry to 8% for energy efficient masonry wall. With the use of the blocks in the floor/roof as filler material, the energy content can be reduced from 100% for a conventional slab to 59% for SCF block panel. As the blocks are true and square, there is no need of plastering and on an average the overall reduction in energy achieved would be 74%. The reduction in GHG emissions with energy efficient construction using carbon neutral block (SCF block) is 68% compared to conventional construction. The research work presented in this paper envisages high potential for carbon neutral block in reducing GHG emissions besides making the house cost effective to the extent of 40%.
