SMART BUILDINGS & IOT FEATURE


From standard to smart S


Isle of Wight council staff have more information about the energy use and environmental impact of a local leisure centre, following a project to provide data for an EU-wide study analysing how the smart cities of the future may operate


iemens and the Isle of Wight Council chose the Heights Leisure Centre as a


pilot project to see whether energy demand could be reduced, as well as using it to evaluate how smart building management systems can be incorporated into existing infrastructure to create a smart building. As part of the project, Siemens’


engineers, working in conjunction with local controls and automation engineers from FW Marsh, integrated the existing building control and energy infrastructure with a smart building management system, turning a conventional building into a connected building. The work, part of the ongoing


EU-funded InteGRIDy project, included analysis of how the centre’s building management system worked, looking at where improvements could be made, and which loads could benefit from remote demand response control. While the centre had a functioning


building management system to control many of the primary energy sources, it didn’t provide the level of data needed to analyse energy use effectively. To be able to analyse the data, the team installed the Siemens Navigator system, a cloud-based data collection and analytics platform which helps the user understand where


and when energy is being used and what is happening in the centre’s spaces. Once installed and working with the


existing system, the platform began to provide engineers with 18,000 new readings from 60 data points daily for analysis. This includes data which helps identify continued operation of systems when the building is closed, to finding the optimal air temperature that balances energy, comfort and impact to the building. This could lead to changes being


implemented which would allow people using the building to experience more comfortable temperatures, the Council seeing reduced energy bills, and reduced carbon emissions. Mark Byvelds, energy engineer from


Siemens Building Technologies, says: “This has been an incredible project to work on which has started a conventional leisure centre on the journey to becoming a smart and connected building. “We live in a world of big data where


buildings and more importantly, their occupants, have a great opportunity to benefit from detailed analysis of this data. “The result of this could lead to greater


transparency on how the centre operates using the data analysis services running in the background to identify opportunities


to reduce operating costs, increase energy efficiency and improve comfort for the centre’s visitors. “This project demonstrates how a


conventional building can become a smart building and proves that existing buildings can become easily connected with the right know-how.” The Isle of Wight Council’s cabinet


member for environment and heritage, Councillor John Hobart, says: “We are very pleased to be supporting this innovative approach to understanding the energy used by council facilities, and the potential for closer control of our systems offers great opportunities for reduced running costs and a more comfortable environment for users.”

Gateway device helps unlock smart sensor data


Pressac Communications has unveiled a new gateway device which makes it easier than ever to get sensor data into the cloud - ready for use wherever its needed


T


he new device means that information on everything from room


occupancy to temperature can feed easily into software or IoT platforms. The gateway works by turning the


data gathered by the sensors into MQTT format, the most commonly used language for IoT devices. The data is then securely available locally or via the cloud. Jamie Burbidge, digital solutions -


product manager at Pressac, says: “Before we introduced this device our customers would often be concerned


about how to get the data out of their smart sensors and into a format that worked for them. “They would usually need to purchase


an additional piece of equipment from another manufacturer to get the data where they needed it. Our gateway device eliminates the need for this by taking the data and converting it in to MQTT. “The information can then be sent


straight to popular platforms like IBM Watson or Microsoft Azure, giving you instant access to data about your buildings.


 “It’s a simpler, cost-effective way for


our customers to unlock sensor data and means they can get everything they need to do this all in one place.” The gateway can be connected via a


wired ethernet cable, or wirelessly via WiF or LTE (4G), meaning it can be kept off main IT networks if necessary. It comes with ready-made connections


to leading platforms, with future connections planned for Amazon Web Services and Google Cloud IoT.
