BIM based Energy Efficiency Evaluation of Modern Buildings

Building information modelling (BIM) processes, technologies, and applications are rapidly re-engineering the work methodology in the AEC & FM industry. BIM provides a more interactive and integrated approach to design, construction and operation of facilities and aims to provide high end benefits for all. Energy efficient buildings with minimal or positive environmental impacts are considered important in countries worldwide and energy efficiency evaluation is one of the major fields that BIM supports today. The book describes the present scenario with the help of the two case studies and a comparative analysis of the major Energy Performance Evaluation tools. Important aspects such as transition of BIM to BEM and its contents such as building energy management, building performance indicators etc have been discussed. Some light has also been shed on the present building regulation in Germany, since the site location of both the buildings included in the studies is Berlin, Germany. The paper provides a comprehensive insight and points out various aspects that can be used for improvement of the tools, for better energy management and to achieve highly energy efficient buildings.
