On the influence of concrete-straw-plaster envelope thermal mass on the cooling and heating loads for different climatic zones of India

On the thermal performance of naturally ventilated room with straw insulation retrofitted envelope for different climatic zones of India

“…In a review, Gupta et al [47] noted the suitability of straw as a construction material for buildings in India. The potential for energy and cost savings on implementing straw insulation retrofitting for conditioned spaces in Indian climatic zones was evaluated in a recent work [48] by the current authors. The decision to use any material including straw in the building envelope is intrinsically linked to its thermal performance and the highly subjective and localized thermal comfort preferences of occupants of a building for a particular climate.…”

Investigation of the Effect of Optimum Insulation Thickness of Building Exterior Walls on Energy Consumption and Reduction of Emissions

“…Where C I is the cost of insulation material in $/m 3 and x is the insulation thickness in m. The optimum insulation thickness is obtained by minimizing equation (12). Hence, the derivative of C t with respect to x is taken and set equal to zero from which the optimum insulation thickness x opt is obtained as:…”

“…The insulating potential of straw, which is an agricultural waste in the context of India's broad climate, was the focus of this study. They concluded that energy savings in the range of 67-96% can be achieved in the different climatic zones by introducing straw to the outer shell only 10cm in thickness [12].…”

On the thermal performance of naturally ventilated room with straw insulation retrofitted envelope for different climatic zones of India

“…While (1), (2), and (4) comprise of purely quantitative results, the criterion in the transient simulations [48]. Therefore, the DOE-2 model is used in the present study as well.…”

“…The DOE-2 model was found to be giving the results closest to the experimental data. In addition to that, in the work involving the evaluation of energy and cost savings on using the straw insulation in the envelope of a conditioned space[48], the results between the 1-D and 3-D simulations were compared for the experiment duration to reiterate the adequacy of the 1-D model for the analyses carried out on a conditioned space. The DOE-2 model was used in the comparison study as well as later…”
