Abstract

Buildings contribute significantly to global carbon emissions, resulting in high greenhouse gas emissions that contribute to global warming. Stubble burning is a major issue in India, causing severe health and environmental problems every year. The primary reason is the disposal issues associated with rice cultivation by-products such as rice straws and rice husk. This paper aims to explore the means of using building materials made of rice cultivation waste and by-products in making a Net-Zero energy office building, also the possibility of using waste heat from the biomass boilers in running the air conditioning system. A case study of a rice processing plant situated in Karnal, Haryana, where a 3600 m2 office building is planned was selected and iterative simulations were performed to analyse the step by step reduction in the annual EPI (Energy Performance Index) while incorporating energy saving strategies. Energy simulation software Design Builder v7.0 was used to assess the building performance. Life Cycle Assessment (LCA) was also performed to assess the reduction in initial carbon emissions while using low carbon building materials over conventional materials.
