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.

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.

With the construction industry moving rapidly towards Building Information Modelling (BIM), it is essential that various analysis tools used in the Architecture, Engineering and Construction (AEC) domain are interoperable with a non-proprietary data exchange standard such as the Industry Foundation Classes (IFC). Governments worldwide have committed to incorporate fully collaborative BIM in all public sector projects and are also targeting to achieve a zero-carbon building stock. This dual target will require the use of renewable energy system (RES) analysis tools in the early stages of the building design process and establish the need for these tools to be IFC compliant. This book captures the development of a methodology to support RES simulation by using architectural BIM models based on open data exchange standards thereby enhancing their interoperability. Various methods currently used in RES assessment and integrated BIM tools have been reviewed in this research. This book culminates with the idea of a prototype that can be used by architects for RES analysis in conceptual design stages which would facilitate decision making in creating zero-carbon buildings of the future.

Bachelor Thesis from the year 2017 in the subject Energy Sciences, grade: B, Institute of Technology Carlow (Department of Built Environment), course: BSc Energy Management (Buildings), language: English, abstract: In response to climate change mitigation, the EU has implemented challenging regulatory targets in relation to reducing energy consumption in newly-built dwellings. The introduction of the proposed NZEB standard for newly-built dwellings indicates the requirements needed to achieve such standard. By utilizing technologies, such as Building Information Modelling, NZEB dwelling design can be achieved more easily than traditional 2D drafting methods. This thesis investigates the use and accuracy of BIM-based performance analysis technologies in the design of new build NZEB dwellings in Ireland. The background to this research is discussed in the first chapter and in the second chapter energy efficient design strategies along with the fundamentals of BIM and related software are discussed. A NZEB fieldwork case study is investigated in order to gain knowledge into the building requirements required to achieve the proposed NZEB standard. Finally, a NZEB design is implemented using a design framework methodology from conceptual design through to detailed design and compliance checking. It was found that the BIM energy analysis results were 95% accurate in comparison to the official Irish compliance checking software.

"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.
