Integration of BIPV design and energy efficient technologies for low energy building in meeting net zero target

Based on the World Energy Transition Outlook, almost two thirds of the CO2 emissions released in the world are related to energy emissions with 36 Gigatonnes of energy related CO2 released in 2015. To reduce CO2 emissions by 70% before 2050, energy efficiency parameters and renewable energy systems will have to be incorporated together to achieve a more sustainable future. The synergy between these two systems could potentially decrease the total final energy consumption of the world by 25EJ, which is by 5% by the year 2030. One of those synergy methods would be the incorporation of energy efficient building designs and technologies with BIPV systems. Energy efficient building design is the process of upgrading or constructing buildings or elements that are able to maximize the consumption of energy supplied to them by reducing energy losses, through various innovative and effective systems and technologies. BIPV systems are PV products and components that are integrated into the buildings structure. In Malaysia, research and applications of BIPV are just emerging and is still in early development. In the final report submitted to the United Nations Development Program, Malaysia aimed to achieve an increase of 330% in installed BIPV capacity. This paper aims to simulate an energy efficient building through a specific 3D modelling software, Autodesk Revit, that incorporates BIPV design systems. The method used to create this model will be performed in four stages. First, the development of a comprehensive 3D model of a suitable building. Second, analysis of photovoltaic system of the model. Third, an intricate energy analysis of 3D building and BIPV system via Revit and Autodesk Insight. Lastly, evaluation of the energy consumption of the building and CO2 emissions. This research has managed to reduce the Final Energy Use Intensity of the building from 194 kwh/m2/year to 140 kwh/m2/year and the CO2 emissions from 258 metric tonnes CO2e to 186 metric tonnes CO2e a year. This research presents the integration of energy efficient designs and technologies, with BIPV systems toward low energy building target.
