The Synergy of Building Information Modelling (BIM) and the ETL

Maximising energy efficiency

As digital technologies continue to advance, Building Information Modelling (BIM) is transforming the construction landscape, by providing a comprehensive digital platform that combines data, processes, and stakeholders to optimise building performance and sustainability.

This article, the second in our series, further explores how BIM principles and methods correspond with the goals of the ETL. It examines the synergy between BIM, which enables collaborative decisions during a building’s lifecycle, and the ETL, emphasising their combined effect on improving energy efficiency in buildings.

Understanding BIM and the ETL

The alignment with government strategies for the adoption of BIM in the UK is a key subject of discussion. As a government-funded programme, the ETL is well placed to support these initiatives by listing technologies relevant to UK building projects, which are within the scope of BIM. By collecting and publishing product information used in the digital description of built assets (i.e., BIM), the ETL plays an important role in standardisation efforts, streamlining the specification process for energy-efficient equipment. Ultimately, facilitating access to this information is a significant step towards accelerating the adoption of energy-efficient technologies.

The journey of integrating BIM into the ETL began with a comprehensive thematic study as part of the 2020/21 ETL Research Programme, conducted collaboratively with industry experts, technology providers, and other key stakeholders, to assess the potential synergies between BIM and the objectives of the ETL. Notably, the study highlighted the complexities inherent in specifying ETL-listed products within an evolving digital landscape. For example, while the procurement of ETL-listed products like refrigerated display cabinets in supermarkets exhibits a straightforward chain of decision-making, the challenge lies in integrating ETL products into new build and retrofit projects through BIM.

The consultation process

The ETL consulted with a number of stakeholders in the digital engineering space, these included Building Smart Data Dictionary (bsDD), CIBSE, NBS, CPA, BEAMA, BSI, UK BIM Alliance, Trade Associations and individual product manufacturers and suppliers. As part of this consultation process qualitive questionnaires were shared with relevant stakeholders.

These consultations highlighted both the opportunities and challenges of integrating BIM objects into the ETL, with stakeholders emphasising the importance of standardising product data and aligning with industry standards to better serve the evolving needs of the construction sector. The diverse input received during this process has been instrumental in shaping the ETL’s approach to potentially supporting BIM compatibility and enhancing digital collaboration.

Challenges and opportunities

To effectively realise the potential synergies between digital construction and energy-efficient technologies, a number of strategic recommendations were proposed for consider for further evaluation. These include:

• Support standardisation of product information for digital design and construction by aligning digital data on the ETL, with national initiatives led by the Government, chartered professional institutes like CIBSE and standardisation entities including the UK BIM Framework, BSI, and NBS.
• Adapt and align the ETL sub-technologies with Product Data Templates (PDTs) and adjust the eligibility criteria and application process to correspond.
• Streamline and simplify the ETL application process by incorporating Product Data Sheets (PDS), including completed PDTs to increase product application rates.
• Allow manufacturers and suppliers to upload PDS and BIM Objects for ETL listed products onto the ETL website. This would enable information to be downloaded from the ETL site and delivered via the ETL API promoting specification of ETL listed products and supporting the effective implementation of BIM.

The proposed enhancements align with the digitalisation efforts spearheaded by the former Centre for Digital Built Britain; a partnership between UK Government and the University of Cambridge, that completed its 5-year mission to cater to the evolving needs of stakeholders in the construction ecosystem in 2022.

The ETL is also currently evaluating the possibility of adding the functionality to upload PDS and BIM objects for listed products. As part of this evaluation, the ETL will be surveying both manufacturers and purchasers in the Autumn of 2024 to gauge the level of interest and potential uptake.

Government and stakeholder involvement

The UK government, and all centrally funded government departments, currently sponsor projects at BIM Level 2 reflecting a commitment to fostering collaboration and digitalisation within the construction sector. The UK BIM Framework, based on ISO 19650 standards, provides the overarching approach to BIM implementation, emphasising the need for efficient transfer of information and informed decision-making throughout the asset lifecycle.

Stakeholder feedback underscores the need to standardise product parameters and focus on PDTs and PDSs. By aligning with industry standards and embracing interoperability, the ETL can meet the needs of building designers and stakeholders, encouraging the use of energy-efficient technologies.

Advancing sustainable practices

Ultimately, the interoperability of the ETL with BIM offers a pathway towards maximising energy efficiency and sustainability in the built environment. By leveraging digitalisation and standardisation, the ETL can enhance its reach, streamline decision-making processes, and foster collaboration across the construction ecosystem.

In doing so, it not only advances the government's energy-saving objectives but also reinforces its position as an advocate of sustainable practices.
