ABSTRACT

The building sector accounts for 40% of the total energy consumption in the EU. It faces great challenges to meet the goal of transforming the existing building stocks into near zero-energy buildings by 2050. The development of Energy Performance Certificate (EPC) schemes in the EU provides a powerful and comprehensive information tool to quantitatively predict annual energy demand from the building stock, creating a demand-driven market for energy-effective buildings. Properties with improved energy rating have had a positive impact on property investments and rental return because of the reduced energy bills. In addition, the EPC databases have been applied to energy planning and building renovations. However, it should be mentioned that the current evaluation system faces problems, such as not being fully implemented, delivering low quality and insufficient information to stimulate renovation, therefore requiring improvements to be made. This paper provides a review of the current EPC situations in the EU and discusses the direction of future improvements. The next generation EPC should rely on BIM technology, benefit from big data techniques and use building smart-readiness indicators to create a more reliable, affordable, comprehensive and customer-tailored instrument, which could better re-present energy efficiency, together with occupants’ perceived comfort, and air quality. Improved EPC schemes are expected to play an active role in monitoring building performance, future energy planning and quantifying building renovation rates, promoting energy conservation and sustainability

ABSTRACT

Building information modelling (BIM) has been proven to be a useful tool allowing sharing information with enhanced collaboration at the building design and construction processes. To this context, BIM contains the required information that could be extracted and transferred to Building Energy Modelling (BEM) software systems to perform energy simulation. This study testified the BIM to BEM process on the most prominent BIM tool Revit and 6 different BEM tools, including Revit Green Building Studio, Openstudio, Designbuilder, Grasshopper (Honeybee), Pleiades and IDA ICE to examine the interoperability gaps from BIM to BEM. Industry Foundation Class (IFC) and Green Building XML (gbXML) are used for the data information transfer between the tools. This study seeks to investigate the recent development in building energy simulation and the technology capability of integrating BIM for building energy analysis. The BIM to BEM process contributes to the automation of building energy simulation. Compared with traditional building energy simulation practices, the creation of BEMs directly from BIMs offers great time saving in the effort for gathering data and geometry construction, and reducing the burden of work for energy study. The BIM to BEM process is testified in 6 energy simulation tools. Results show that for each tool there exists certain kind of information misinterpretation in terms of building components and material properties. Modification and additional information are required before conducting energy analysis. The potential usage of the different tools by architects for energy efficient design or by engineers for HVAC system optimization is discussed.

ABSTRACT

This paper presents a newly constructed smart low carbon district energy network in Belval, Luxembourg. The district was the site for the largest steelworks in Luxembourg and currently a majority of the site is renovated into a new modern community with university, research institutes, banks, shopping malls, hotels and residential apartments. The waste heat generated from the remaining steel factory is recovered to provide heating to the district, which covers 70% of the heating requirements. PV panels will be installed on the roofs of a building for electricity supply. The CUSP (Computer Urban Sustainability Platform) developed by Cardiff University is deployed to simulate dynamic management of the energy network to achieve the smart energy vision. Relying on a semantic framework, the system enables gathering site and building datasets together with Building Information Modelling (BIM) for building management. The platform enables interactive monitoring and informed decision making based on developed artificial intelligence for energy prediction and optimization algorithms for energy dispatch. The smart energy network will greatly enhance renewable energy penetration, reduce CO2 emission and minimize operation costs in the district.

ABSTRACT

Construction industry has a wide  impact on the  socio-economic development of any nation. It employs a large number of population and contributes to a nation’s built wealth -buildings and infrastructure. In  contrast,  this sector  has  an  adverse  environmental  impact  and  is responsible  for  high  energy  use,  greenhouse  gas  emissions, resource  consumption,  solid  waste  generation,  environmental  damage  and  pollution.  Energy efficient  (EE) buildings are an important and cost-efficient  way today to mitigate  the  release  of greenhouse  gases. Moreover, technological changes namely building information modelling (BIM) has brought about a digital transformation in the industry and have  significant  interest  across  Europe.  This  has  created  a  potential  for  a  better  digital management of energy-efficiency of buildings and –concurrently -a huge demand in new skills and competence requirements for the construction workforce -professionals, managers, labors as well as engineering students. This paper presents the objectives and discusses the challenges and initial results of BIMEET (BIM-based EU -wide  Standardized  Qualification  Framework  for  achieving  Energy  Efficiency)  research  program  funded  under H2020 program. BIMEET project aims to leverage the take-up of ICT and BIM through a significant upgrade of the skills and capacities of the EU construction workforce. The paper provides an overview of the BIMEET project and discusses the use cases that especially will need a description of skills related to BIM and energy-efficiency. Such descriptions should rely on the European Qualifications Framework in order to be standardized across Europe and countries’ specific competencies and training schemes. The paper finally defines the purpose of the training platform aiming to widely disseminate  the  BIMEET  outcomes.  The platform will support registering  labelled training offering and finding suitable BIM training in different levels of AEC sector.

ABSTRACT
Construction industry has a wide impact to our built environment. It plays a vital role for governments and supports in both developed and developing economies. The industry supports economic growth of a nation through various trades and activities as well as provides new jobs. It is one of the largest industrial sectors that has a projected output of 13.5% by 2025. Climate change, resource depletion and rapid urbanization are the most severe amongst the challenges we face today. The construction industry alone is responsible for 20% of the global energy consumption and approximately one-third of energy-related CO2 emissions. The industry entails the high energy saving potentials and provides various opportunities to implement sustainable solutions to decrease the environmental impacts and  thus  lower  greenhouse  gas  emissions.  In  the  construction projects  today,  we  can implement  different  energy  efficiency  strategies  and  products virtually  during  the  planning  phases  of  the  construction  projects  using  model  based environment  and  tools  commonly  known  today  as  virtual  design  and  construction (VDC) as well as building information modeling (BIM). We can  accurately simulate and  calculate  the  impacts  and  thus  support  the  increasing  demand  of  complex  high-performance  buildings  in  order  to  effectively  address  energy  and  carbon  reduction targets.  However,  one  of  the  key  challenges,  the  industry  faces  is  the  availability  of skilled workforce and experts that have enough BIM and energy efficiency skills.  The paper addresses such needs and presents the current status of a H2020 project with a focus on defining roles and responsibilities construction project stakeholders have for the energy efficiency measures along the different project phases. It also provides an outlook for the development of the learning outcomes based on knowledge, skills and competence   (KSC)   framework   as   well   as   systematically   presents   the   base   for harmonization of the learning outcomes at the EU level.

ABSTRACT

With the new regulations and policies related to climate change, the construction industry has been put under pressure to increase the sustainability of its practices. Many organizations are now adapting their processes to meet government legislative targets (e.g. reducing carbon emissions) and consider the environmental, social and economic performance of buildings. Such strategies have managed to improve current practices in managing buildings, however decarbonizing the built environment and reducing the energy performance gap remains a complex undertaking that requires more comprehensive and sustainable solutions.

In this context, Building Information Modeling (BIM) can help the sustainability agenda as the digitalization of product and process information provides a unique opportunity to optimize energy efficiency-related decisions across the entire lifecycle and supply chain. BIM is foreseen as a mean to waste and emissions reduction, performance gap minimization, in-use energy enhancements, and total lifecycle assessment.

A virtual collaborative platform that provides integrated access to BIM resources in the form of interactive, dynamic, and user-oriented services that fully exploit latest advances in computing technologies may address these barriers. 

In this paper we present how a virtual collaborative system can be efficiently used for implementing BIM based energy optimization for controlling, monitoring buildings and running energy optimization, greatly contributing to engaging BIM construction community with energy practices. The solution described, known as energy-bim.com platform, disseminates energy efficient practices and community engagement and provides support for building managers in implementing energy efficient optimization plans.
