The simulation results show the possible façade design that can efficiently control the amount of insolation, maintain a satisfactory quality of indoor environment, contribute to the reduction in energy demand, and at the same time support and consolidate the architectural vision. The analysis done during the study highlights the importance of reducing the heat gain through the building envelope and improving the thermal comfort level and energy efficiency in residential buildings in Chennai. It is concluded from the simulation results that by proper use of shading devices and window glass help in the reduction of energy consumption wherein the roof construction showed less energy benefits. These energy consumption factors can be reduced by using appropriate technology for designing the building envelope, which plays an important role in the consumption of energy in the building. Conclusionīased on the study and analyses, there are several factors which contribute to energy consumption in the building, including: Higher efficiency panels cost more, but they produce more energy for the same floor area. Panel efficiency which is attained by the percentage of the sun’s energy that will be converted to AC energy. ![]() The efficiency in daylighting an occupancy control can be achieved by usage of advancement in technology for daylight dimming and occupancy sensor system.Ĩ. Lighting efficiency - average internal heat gain and power consumption of electrical lighting per unit floor area is lower based on the reduced usage of lighting during the day which is attained by proper availability of daylight.ħ. Wall construction helps in reducing heat loss and heat gainĦ.

The study summarizes the design parameters for effective building envelope design from the simulation results to reduce the dependency on active means of a mechanical system, which in turn helps to improve thermal comfort. The base model was developed in Revit and simulated in Autodesk Insight and Autodesk Green Building Studio. We explore how to improve thermal comfort through quantitative analysis of the effect of thermal characteristics of the exterior building envelope. This research focuses on the energy performance of the building envelope of a high-rise residential building in Chennai, India. It is not yet known in what way building envelope design measures are to be selected and the performance in hot and humid climates. Envelope systems pose a great scope to reduce the energy consumption and consequently improve building efficiency. This was an eye-opening situation for people all around the world, thus promoting energy-efficient solutions for the buildings. Greenhouse emissions due to the maximum usage of the mechanical system for active cooling of the building has created greater impact on our fragile ecosystem. Rapid urbanization has resulted in exploitation of the available energy resources. The BIM tools helped the designers to experiment with all possible design alternatives before the execution for the final design solution, which saves money and time while simultaneously contributing to more energy-efficient building design. ![]() These tools were used to study the energy performance and thermal comfort of an existing building to reduce the dependence on the mechanical system of the building through retrofitting strategies. ![]() This article shows the flexibility and consistency of energy analysis performed with BIM-based simulations such as Revit, Insight, and Green Building Studio.
