BIMcert partners highlight energy savings

The BIMcert partners have produced a new paper called, ‘Delivering Energy savings for the supply chain through Building Information Modelling as a result of the Horizon 2020 Energy BIMcert project’.

The exploitation and utilisation of energy resources have caused severe ecological and environmental problems, including the production of emissions that contribute to global warming (Enshassi et al., 2018). The construction industry consumes up to 50% of mineral resources excavated from nature, generates about 33% of CO2 present in the atmosphere and is responsible for 40% of total global energy through both construction and operational emissions (Ajayi et al., 2016 and Zhou and Azar, 2018). This has resulted in the AEC Sector (Architecture, Engineering and Construction) out of necessity being forced to investigate new methods of practice and how best to apply resource-efficient techniques from the extraction of the raw materials to the demolition and disposal of its components.

The realisation that practices now face globalization, sustainability, and environmental concern, as well as ever-changing legislation requirements and new skills needed for the information age has resulted in technologies such as Building Information Modelling (BIM) becoming a key enabler in navigating these concerns (Jaradet, 2014). BIM can be defined as a modelling technology and associated set of processes to produce, communicate, and analyze building models (Sacks et al., 2018). BIM provides an opportunity for the Architectural, Engineering, Construction, and Operation (AECO) industry stakeholders to evaluate possible solutions and identify potential problems of the final product before the start of actual construction (Badrinath et al., 2016).

However, changing from traditional practices to BIM requires a shift not only in the technology used but also in the way design and construction teams work together (Shelbourn et al., 2017). To achieve the associated benefits that are accustomed to BIM a number of existing challenges to ICT (Information, Communication, Technology) utilisation in construction site management must be overcome which include a lack of knowledge, skills and competence, depth of understanding of decision makers and low ICT literacy (Ozumba and Shakantu, 2017). This BIM movement has also resulted in a clear, direct, and automatic impact upon engineering education systems (Jäväjä and Salin, 2014).

To assist in overcoming these barriers, so as to reach EU energy-related targets a number of funding initiatives have been put in place through Horizon 2020 with a focus on BIM, as a result of it having the potential to rapidly produce energy outputs that enable design teams to analyse and compare the most cost-effective, energy-efficient options. Such an initiative is the Energy BIMcert project, which aims to educate all areas of the supply chain in the use of BIM, to achieve better energy efficiency during the design, construction and ongoing maintenance of an asset.
