EVENT | BUILD2PERFORM schools designed today are going to struggle with a warming of two degrees, and even more so with four degrees. In another study, using Department for Education building in-use surveys of 70 schools over three years, it was found that they used twice as much energy as predicted, said Joe Jack Williams, of Feilden Clegg Bradley Studios. However, environmental rather than energy data was difficult to obtain because the schools didnt want to share it for liability and PR reasons. Digital trailblazers The Society of Digital Engineering Awards and Building Simulation Awards were announced at Build2Perform. They showed how technology can be harnessed to create accurate building models quickly, which can be used during a buildings lifetime to ensure environmental targets are on track. The winners (see page 13) are pioneers, and there are fantastic examples of digital models of buildings being used as real-life models such as Newcastle Universitys Urban Sciences Building Centre, which multiple winner BuroHappold Engineering helped design. A more downbeat assessment of the industrys practical use of digital technology was made by Thayla Zomer, a researcher at the Centre of Digital Britain. Evidence shows BIM is not yet business as usual, she said, referring to a NBS 2019 survey that revealed 40% of respondents who said they had adopted BIM werent actually using standards essential for it. Dan Cash: IoT is in a trough of disillusionment ZERO INCIDENT, DEFECT AND WASTE At the session on offsite construction, Is zero incident, defect and waste possible?, Dale Perini, of Bryden Wood Technology, spoke about the GlaxoSmithKline (GSK) Beta building prototype a pharmaceutical facility that can be built to international standards anywhere in the world, using local skilled labour. The Ikea-inspired factory in a box produced in response to GSKs need to develop factories and packaging facilities in Africa and Asia fits into a shipping container, and comprises a simple set of instructions and made-to-measure components. Perini said eight former Gurkhas, unskilled in construction, built a defect-free pharmaceuticals facility from components delivered in shipping containers, packed in reverse order for the reassembly process, in 12 weeks, resulting in a 60% reduction in programme and 70% reduction in labour compared with a standard build project. David Bradley, of E+I Engineering Group, said offsite manufacture cuts out time on site, as equipment is tested and commissioned in the factory and does not need to be tested again. To ensure their electrical rooms and skids which are pre-cabled can be delivered on lorries, he said the switch gear has been narrowed to ensure no road closures for wide loads are needed. The equipment within the units has also been equally balanced, to allow easier lifting by crane. There are social benefits too, said Lewis Jones, of Prism. Its manufacturing facility is not a construction site, so workers who have four-day weeks spend less time travelling and looking for accommodation. This cuts emissions associated with travel, and power to keep things on, he said. There was a decoupling of policy and practice, Zomer added, with an overemphasis on technology by academia and not enough focus on the change in processes required to implement BIM. Adoption needed to be motivated by legitimate reasons rather than technology, she said. In the same session, Dan Cash, senior lecturer at the University of the West of England, spoke about how the Internet of Things (IoT) is struggling to be implemented in buildings. Expectations for the technology had been over-inflated, he said, and IoT was currently in a trough of disillusionment. He quoted a report by Cisco, which found that 60% of IoT initiatives stall at proof-of-concept stage. Cash said it should be used to optimise building systems, and that automated seasonal commissioning offered an opportunity to improve building performance. He showed an example of how IoT could be achieved, at a demonstration project by Atamate in Cardiff. Six new, insulated flats had all-electric building services installed, with one featuring occupancy-based heating and ventilation. Sensors communicated with the buildings local hub. This connected to the cloud, where algorithms are being developed to optimise and maintain services. Energy demand for the flat with occupancy sensors was 11.7kWh.m-2 per year and Cash claimed the capital costs were below average. We need to get to a process of continually collecting data so buildings can perceive 26 January 2020 www.cibsejournal.com CIBSE Jan20 pp24-27 Build2Perform v2.indd 26 20/12/2019 15:14
