15 Life Is On | Schneider Electric www.se.com 2021 Sustainable Development Report Spotlight on Building Management Systems (BMS) Due to their high energy use and the carbon generated during their manufacturing and construction process, buildings account for nearly 40% of global greenhouse gas (GHG) emissions. Decarbonizing buildings and ensuring their efficient energy usage requires the implementation of smarter solutions and thereby helps combat climate change. Such activities are qualified as “Manufacture of energy efficiency equipment for buildings” (3.5) in the EU Climate DA. Our EcoStruxure ™ Building Operation solution is a scalable, open integration software platform at the heart of the building management system that facilitates control, monitoring, and management of building assets. It offers users a single pane of glass window for efficient monitoring and operations of building systems to enable improved building efficiency, asset utilization, uptime, and occupant comfort through integration of HVAC, electrical, lighting, security, fire, power, and other subsystems. By monitoring, controlling, organizing, and acting on disparate data from building assets to a single system through advanced connectivity and integration with heterogeneous building systems, our solution brings better visibility and decision-making processes, optimizes how and when energy is used, and enables proactive energy reduction. For example, our solution for the Cinnamon Grand Colombo, Sri Lanka’s largest hotel, helps save 4,000 metric tons of GHG emissions annually. Even though energy savings equipment had been previously installed, the operations staff was not able to identify specific areas where energy was being wasted. There was a need to gain visibility into the data to develop effective energy savings strategies. After conducting an initial energy audit, an upgrade of the hotel’s existing BMS to Schneider Electric’s EcoStruxure ™ Building Operation solution was recommended. At the Cinnamon Grand Colombo, the EcoStruxure ™ solution integrates the hotel’s electrical and mechanical plants, which include building systems for air conditioning, exhaust, ventilation fans, pumps, steam and hot water boilers, energy meters, and high efficiency, magnetic bearing chillers from Smardt. The result provides efficient energy monitoring, management, and reporting that drives savings across the entire hotel. Delivering environmental benefits through industrial automation Schneider Electric works hand in hand with industrial enterprises to automate their operations, and in doing so, helps them reduce or eliminate carbon emissions and optimize their use of resources. From smart sensors and connected devices to advanced process controllers with software analytics on the top, industrial automation systems enable better monitoring, control, and optimization strategies to directly improve energy performance, and indirectly, improve maintenance to prevent an increase in energy use due to plant downtime and resulting startup and shutdown processes, as well as defective products. Advanced supervision also enables to mitigate environmental pollution risks. As such, they are major enablers to mitigate climate change, pollution prevention and support the deployment of a circular economy Traditionally, industrial operators have been blamed for climate change, resource scarcity, and harm to the environment and the society around them. Today, industry contributes 32% of the world’s CO 2 emissions. At the same time, many of the most energy intensive industries produce the essential building blocks for society and key components of our modern world. According to the BloombergNEF report, Digitalization: An Untapped Pathway to Sustainability, industrial digitization promotes decarbonization and circularity, reduces material waste, prolongs equipment lifetime, and enables better emissions monitoring. Schneider’s teams have seen it firsthand with our industrial customers. For example, Schneider Electric supported EastLink to improve the ventilation system of the EastLink freeway tunnels in Australia for better energy efficiency and a reduction in noise levels from the ventilation stacks: • Auditing the energy usage of the tunnel system, Schneider identified areas where significant energy savings could be made. Since the opening of EastLink, the speed of airflows within the tunnels and stacks was controlled in a traditional way - by switching individual fans on and off at pre-programmed times of the day. When switched on, a fan always operated at full speed. This was inefficient, using more electricity than necessary and producing high operating noise levels. It was also causing unnecessary wear and tear on components. • To address the energy usage and noise issues, Schneider worked with EastLink to upgrade ten large ventilation fans from fixed speed fully off / fully on operation to a much more efficient self-regulating or closed loop variable speed operation. An on demand ventilation system using Schneider Electric EcoStruxure ™ architecture, Modicon M580 PACs, Altivar Process variable speed drives and an AVEVA Plant SCADA system was implemented to bring together automation, connectivity and software for real time control and visibility. • The upgrade has reduced energy use by almost 70% and the carbon footprint reduction by 9,000 tonnes per annum. This is thanks to the use of the EcoStruxure ™ for Industry solution with the variable speed drives, and the control algorithms in the M580 PAC which means the fans are only ever operating at the speed that is required at the time. This reduction in fan usage will also see an increase in the fan life because of the lower stresses applied to the drive motor and impeller. The upgrade with Schneider Electric has contributed to EastLink being awarded the top 5-star GRESB sustainability rating. GRESB has ranked EastLink number 1 private entity road company in the world, and number 5 of 280 infrastructure assets of all types around the world.
