Abstract
The green building revolution is sweeping across not only developed countries but most of the world. It’s a revolution inspired by an awakened under- standing of how buildings use resources, affect people, and harm the environment. There are multiple green energy techniques, such as thermal technology natural ventilation, natural lighting, and renewable energy. Renewable energy, especially solar energy, is more widely using in the green building, solar building does not just pass the light and heat of the sun in order to light up and heat the building. But today, the GBs uses solar energy by adopting ‘active’ and ‘passive’ systems. During the early design phase, designers rely on general design guidelines with a lack of the use of an assessment tool to estimate the efficiency of the design results. For the past 50 years, a wide variety of building energy simulation tools have been developed which are essential in the design process to assess the complex physical interactions within buildings. The concept of Building Information Modeling (BIM) has gained international attention in recent years, up to inclusion in strategic energy policy papers in several countries. Use of BIM based energy modeling provides several benefits including: more accurate and complete energy performance analysis in early design stages, improved lifecycle cost analysis, and more opportunities for monitoring actual building performance during the design phase. BIM in conjunction with Building Energy Modeling (BEM) seeks to make this integration seamless throughout the design process. BEM can be used to improve energy efficiency through adjustments to system operations and building retrofits. Successful implementation of BIM is able to eliminate the extra cost of design changes during the subsequent phases of design process. BIM, therefore, is also capable of enhancing the performance of the project. BIM solutions can contribute to the selection of best solutions to reduce energy and resources consumption. This new technology and the approach also can generate the need of more innovative professionals and job opportunities. The thesis highlights the definitions, design process guidelines, energy analysis, and benefits of BIM with the aim of providing a clear understanding of developing energy conservation solutions. It then explains the importance of using various energy simulation software during the early design stage that influences better design of energy efficient buildings. The thesis then moves on to provide an analytical examples to manage green building construction process, including the design process, by using BIM techniques. A practical method is then outlined through an energy simulation tool Revit Graphical User Interface (GUI), incorporating the Insight 360 calculation engine, to investigate the total energy consumption and the possibility of creating an energy modeling to act as an early energy efficiency design prediction and finds the optimum choice of each stage of the design process. The finding of this thesis show that BIM is found to be ideally suited to the delivery of information needed for improved design and building performance. The most significant benefit of BIM for sustainable building design is reaching the optimum performance of buildings with the lowest cost.
