Modeling and Comparison of Energy Efficient Green Building With Conventional Building for Different Climatic Zones

Abstract

Green energy efficient building is one scientific approach which is gaining a lot of attention in the construction industry due to its sustainability and environment friendly approaches. In 21st century, world is seeing rapid growth in construction phases to meet the needs of people at any cost. This arise the demand for the well documented, integrated solution in pre project planning including choosing of greener materials, adopting water and energy saving techniques in and around the built environment. Various international and national organizations* are working integrally to make efficient and effective solutions to cater the ways out for meeting the maximum demands of greener solutions and rely less on demands for natural resources. This topic is worthy of study because it allows the worthy health and living by implementing improved and integrated design strategies which are surely efficient and effective. Steady heat flow is taken for modeling of the building on different climatic location. Material is selected on the basis of their thermal and mechanical properties. From the above modeling , heat loss and heat gain from inside of the house is find out so that the thermal comfort within the house is find out on the basis of maintaining the indoor air temperature accordingly w.r.t. the ambient air temperature outside of the house. Main purpose of the design is to build the house in a way to provide the maximum thermal comfort within the building without using or minimal use of thermal control devices for providing comfortable environment within the building. This strategy uses some of the designs features aided by organizations working with green environment to achieve the optimum certification level. Cold and cloudy region uses passive heating concepts and composite region uses passive cooling concepts. Maximum use of sun for the heating purpose, orientation of the walls and windows with respect to the sun, adopting shading techniques improved the thermal comfort in these locations. The thesis study is mainly is to find out the energy analysis and cost effectiveness of the green buildings built for different climatic zones and comparison of it with the conventional building. Modeling and analysis is done for the improved energy efficient structure which has improved building performance, reduced life cycle energy cost, reduced monthly heating and cooling loads, energy generation potential, savings in electricity bills. Modeling is done using software like , AUTODESK REVIT 2016 and MS EXCEL for calculating the Qi, Qm, Qc, Qv, Ti values for the spaces. Detailed construction cost for green the buildings are calculated for the different regions and it has been compared to the conventional buildings. DSR-2016 rates are taken to find out the detailed cost for each time and abstract of cost is made .
