Climatic Parameter Analysis on Building Materials for Kolkata, Eastern Zone of India

Abstract

AbstractAdvanced building materials have significant contribution for developing better construction and retrofitting of present buildings, and this can be possible by understanding the various building performance parameters through proper planning and design. However, today’s unpredicted climatic variation has a major role for the selection of building materials for construction of house and buildings all over the world. Keeping these on mind, the current investigation is focused on the influence of climatic condition on the existing and advanced buildings materials. The climatic zone of Kolkata as a major city from eastern zone of Indian subcontinent is selected. The overall year’s performance on different building materials, considering these materials for wall as well as roof of a building. The objectives will focus on the influence of the conventional materials, advanced alternative building materials and bio-based insulating materials. This will be helpful in developing thermal comfort building and an energy-efficient occupation. Apart from these, the role of overall heat transfer coefficient will definitely be helpful for the designers to develop a building. The effect of various wall and roof configurations on thermal load is studied according to all-weather conditions. The investigation exhibited that addition of bio-based insulation increased the time lag value up to 10.97 h and thermal transmittance value around 0.665 W/m2 K.KeywordsBuilding materialsClimate comfortWeather conditionsBio-based insulating materials
