 DIGITAL DECARBONISING 
 FMJ AIMS TO SUPPORT TECHNICAL EXPERTISE IN THE FM MARKET 
 Sadaf Askari, ICL Partner Business Manager at IES explains the beneƛ ts to FMs in bringing digital innovation into ESG strategies 
 Robust ESG (Environmental,  
 Social and Governance)  
 strategies are important not just  
 to curb global warming, but to  
 reflect an increasing awareness by  
 consumers, partners and investors  
 that net-zero buildings also have a  
 financial benefit. 
 Facilities managers can turn to  
 digital innovation to assess the carbon  
 e iciency of a single building or an  
 entire portfolio, to see where changes  
 need to be made to reduce the carbon  
 footprint. One area that has had  
 some incredibly beneficial results is  
 Digital Twins. This technology allows  
 building managers to see a digital  
 or virtual version of their facilities to  
 assess and improve their e iciency and  
 sustainability status. 
 CREATING THE WORLD’S GREENEST  
 CAMPUS 
 Digital Twins are arguably the key to  
 decarbonising the built environment.  
 These virtual replicas are fully scalable  
 from a single building to an entire city  
 and respond and behave just like their  
 real-world counterparts. Delivering  
 the data-driven information needed  
 to uncover significant energy, carbon,  
 capital and operational savings, also  
 takes resource use, transport and

 socioeconomic factors into account. 
 With the improved e iciency  
 a orded to buildings through Digital  
 Twin analysis, organisations can not  
 only improve the eco-credentials of  
 their buildings but also help to make  
 financial savings. 
 Demonstrating these savings is  
 Nanyang Technological University’s  
 (NTU) 250-hectare EcoCampus in  
 Singapore. NTU wanted to understand  
 at campus level which energy-saving  
 solutions would perform best and  
 identify the optimum scale and  
 location for its deployment. Digital Twin  
 technology enabled NTU to see a full  
 visualisation of its 21 campus buildings  
 complete with virtual testing for  
 building performance optimisation. 
 A masterplanning (iCD) model of the  
 EcoCampus, detailing energy signatures  
 for each building, was created and used  
 as a baseline to simulate and analyse  
 testbed technologies. These ranged  
 from building envelope improvements,  
 to light sensors, chiller optimisation  
 and smart plugs that ensure appliances  
 are switched o  a er hours. 
 During the implementation phase,  
 the best testbed solutions were put into  
 practice by calibrating operational data  
 from utilities and Building Management  
 Systems (BMS) into virtual models.  
 Data was gathered and analysed  
 to investigate faults across the  
 campus’s 21 buildings, for example,  
 high or low CO levels, unstable o   
 coil temperatures and faulty energy  
 meters.  
 A selection of the proposed  
 energy-saving interventions were  
 simulated using the digital twin to  
 determine potential savings, helping  
 to uncover 31 per cent average energy  
 savings, 9.6kt of carbon savings and  
 a total cost saving of approximately  
 $4.7million. 
 DESIGNING THE WORLD’S  
 FIRST NET-ZERO FAST-FOOD  
 RESTAURANT  
 The US’s first net-zero designed  
 fast-food restaurant – McDonald’s at  
 Walt Disney World Resort, Orlando,  
 combines modern architecture with  
 technology to generate enough  
 energy on-site to cover its energy  
 needs on a net annual basis.  
 WSP used IES’s Virtual Environment  
 so ware – part of its Digital Twin  
 technology suite - to conduct detailed  
 and extensive energy analysis to  
 inform the design and ensure it was  
 on track for net-zero targets. 
 With the high volume of meals being  
 served, even the heat gain from the  
 food has an impact on the space. The  
 team virtually tested natural ventilation  
 options using MacroFlo resulting in the  
 eventual implementation of a hybrid  
 HVAC system that uses standard VRF  
 cooling as well as natural ventilation. 
 By gathering data from another  
 McDonald’s, a schedule for each piece  
 of equipment could be created in the  
 Virtual Environment, revealing that  
 grills and fryers were not run all day,  
 despite it being a 24-hour premise.  
 Using real-time data and translating it  
 into more e icient scheduling in the  
 model facilitated a lower energy usage  
 and also gave understanding of the  
 most energy-intensive equipment.  
 OPERATIONAL DASHBOARDS 
 One of the greatest benefits of  
 embedding Digital Twins within ESG  
 strategies is the ability to leverage the  
 ever-growing Internet of Things (IoT)  
 infrastructure to e ectively gather,  
 manage and interrogate operational  
 data across your building or portfolio,  
 in a single pane view. 
 In the case of one UK city council, the  
 energy management team were able  
 to use IES Digital Twin technology to  
 facilitate centralised data monitoring,  
 analysis and proactive maintenance  
 across a portfolio of 35 public  
 buildings. 
 The physics-based simulation,  
 machine learning and AI capabilities  
 of the Digital Twin make it possible to  
 learn from historical data patterns to  
 detect anomalies and create alerts to  
 notify of any unexpected behaviours.  
 This enables energy and FM teams  
 to be much more proactive in their  
 maintenance approach, prioritising  
 repairs and, in some cases, predicting  
 faults before they happen. 
 Digital Twins present an allencompassing  
 solution to analyse and  
 address such considerations, alongside  
 energy and carbon targets, providing  
 yet another compelling reason to bring  
 the technology central to your facility’s  
 ESG strategy.
