"Energy conservation has become a priority for many governments and sustainable building standards such as LEEDS and Estidama. This is largely due to the high energy demand of buildings and the rising concerns over the impact fossil-fuel-generated electricity has on the environment. With buildings consuming up to 40% of global energy, the demand for energy-efficient buildings has steadily increased. This study employs the Building Information Modelling (BIM) technology namely Autodesk Revit and the energy modelling software, IES-VE, to analyze the effectiveness of passive design measures such as the building’s orientation and external envelope on its energy consumption. The analysis was performed on a case-study office building and both thermal imaging and the experimental measurement of the building envelope's U-value were conducted to assist the investigation. The study proves that with just basic knowledge about the HVAC system, the building can be modelled to within 3% of the actual consumption when comparing the colder months. The case-study building was also found to have an EUI of 357.8 kWh/m2/yr according to the model’s consumption, this is relatively lower than the actual EUI of the building of 411.2 kWh/m2/yr obtained using the building’s total estimated consumption. Furthermore, the total savings achieved by increasing the insulation levels of the external wall, adding 100 mm of insulation to the slab on grade, fitting high performance windows, and optimizing the orientation of the building, was 2.77%. The maximum savings achieved from any one efficiency measure, however, was about 1.6%, achieved when using high-performance glazing. It was also shown that although the case-study building had no thermal bridges, all thermal bridges detected on other buildings were about 2°C different from the insulated elements. The study also showed that the U-value calculated by the IES-VE software was 0.2354 W/m2K, differing by 31% when compared to the 0.339 W/m2K as measured in-situ. The study finally concludes that a modern office building gains little benefit from retrofit measures that minimize heat gain, however, the framework of BIM, IR camera, and in-situ U-value measurement proved effective."--Abstract.

This textbook teaches the fundamentals of building energy modeling and analysis using open source example applications built with the US DOE’s OpenStudio modeling platform and EnergyPlus simulation engine. Designed by researchers at US National Laboratories to support a new generation of high performance buildings, EnergyPlus and OpenStudio are revolutionizing how building energy modeling is taught in universities and applied by professional architects and engineers around the world. The authors, all researchers at National Renewable Energy Laboratory and members of the OpenStudio software development team, present modeling concepts using open source software that may be generally applied using a variety of software tools commonly used by design professionals. The book also discusses modeling process automation in the context of OpenStudio Measures—small self-contained scripts that can transform energy models and their data—to save time and effort. They illustrate key concepts through a sophisticated example problem that evolves in complexity throughout the book. The text also examines advanced topics including daylighting, parametric analysis, uncertainty analysis, design optimization, and model calibration. Building Energy Modeling with OpenStudio teaches students to become sophisticated modelers rather than simply proficient software users. It supports undergraduate and graduate building energy courses in Architecture, and in Mechanical, Civil, Architectural, and Sustainability Engineering.

This book charts the path toward high performance sustainable buildings and the smart dwellings of the future. The volume clearly explains the principles and practices of high performance design, the uses of building information modelling (BIM), and the materials and methods of smart construction. Power Systems, Architecture, Material Science, Civil Engineering and Information Systems are all given consideration, as interdisciplinary endeavours are at the heart of this green building revolution.

Building Information Modelling (BIM) is being debated, tested and implemented wherever you look across the built environment sector. This book is about Heritage Building Information Modelling (HBIM), which necessarily differs from the commonplace applications of BIM to new construction. Where BIM is being used, the focus is still very much on design and construction. However, its use as an operational and management tool for existing buildings, particularly heritage buildings, is lagging behind. The first of its kind, this book aims to clearly define the scope for HBIM and present cutting-edge research findings alongside international case studies, before outlining challenges for the future of HBIM research and practice. After an extensive introduction to HBIM, the core themes of the book are arranged into four parts: Restoration philosophies in practice Data capture and visualisation for maintenance and repair Building performance Stakeholder engagement This book will be a key reference for built environment practitioners, researchers, academics and students engaged in BIM, HBIM, building energy modelling, building surveying, facilities management and heritage conservation more widely.

This research book aims to conceptualise the scale and spectrum of Building Information Modelling (BIM) and Artificial Intelligence (AI) approaches in energy efficient building design and to develop its functional solutions with a focus on four crucial aspects of building envelop, building layout, occupant behaviour and heating, ventilation and air-conditioning (HVAC) systems. Drawn from theoretical development on the sustainability, informatics and optimisation paradigms in built environment, the energy efficient building design will be marked through the power of data and BIM-intelligent agents during the design phase. It will be further developed via smart derivatives to reach a harmony in the systematic integration of energy efficient building design solutions, a gap that is missed in the extant literature and that this book aims to fill. This approach will inform a vision for future and provide a framework to shape and respond to our built environment and how it transforms the way we design and build. By considering the balance of BIM, AI and energy efficient outcomes, the future development of buildings will be regenerated in a direction that is sustainable in the long run. This book is essential reading for those in the AEC industry as well as computer scientists.

When used appropriately, building performance simulation has the potential to reduce the environmental impact of the built environment, to improve indoor quality and productivity, as well as to facilitate future innovation and technological progress in construction. Since publication of the first edition of Building Performance Simulation for Design and Operation, the discussion has shifted from a focus on software features to a new agenda, which centres on the effectiveness of building performance simulation in building life cycle processes. This new edition provides a unique and comprehensive overview of building performance simulation for the complete building life cycle from conception to demolition, and from a single building to district level. It contains new chapters on building information modelling, occupant behaviour modelling, urban physics modelling, urban building energy modelling and renewable energy systems modelling. This new edition keeps the same chapter structure throughout including learning objectives, chapter summaries and assignments. Moreover, the book: • Provides unique insights into the techniques of building performance modelling and simulation and their application to performance-based design and operation of buildings and the systems which service them. • Provides readers with the essential concepts of computational support of performance-based design and operation. • Provides examples of how to use building simulation techniques for practical design, management and operation, their limitations and future direction. It is primarily intended for building and systems designers and operators, and postgraduate architectural, environmental or mechanical engineering students.

A sustainable building is constructed of materials that could decrease environmental impacts, such as energy usage, during the life-cycle of the building. Building Information Modeling (BIM) has been identified as an effective tool for the virtual analysis of a building's performance in the design stage to determine the designs that have the largest impact on the building's performance. The main aim of this study was to assess the applicability of BIM in analyzing and reducing the energy consumption of buildings. In the design and pre-construction stages, the building information model (BIM) should be taken into account as a comprehensive simulation method that can be used to create opportunities to assess and improve the performances of buildings. This integration of the BIM concept into the design stage can be used to select the best green building designs and reduce the need for later design modifications that require extra time and cost. The results of the study will be useful to architects and building designers as they use the BIM concept and tools to develop energy-efficient buildings in the future with the goal of achieving sustainable development for society.

The combined challenges of health, comfort, climate change and energy security cross the boundaries of traditional building disciplines. This authoritative collection, focusing mostly on energy and ventilation, provides the current and next generation of building engineering professionals with what they need to work closely with many disciplines to meet these challenges.A Handbook of Sustainable Building Engineering covers: how to design, engineer and monitor a building in a manner that minimises the emissions of greenhouse gases; how to adapt the environment, fabric and services of existing and new buildings to climate change; how to improve the environment in and around buildings to provide better health, comfort, security and productivity; and provides crucial expertise on monitoring the performance of buildings once they are occupied. The authors explain the principles behind built environment engineering, and offer practical guidance through international case studies.
