BUILDING MANAGEMENT SYSTEMS
Controlling energy consumption during textile manufacturing
optimise the technology of the new system to offer a minimum 15% saving on top of what the existing system was achieving. It also provides the opportunity to assess where system improvements could be made by using knowledge of the V16, adjusting sensor locations to improve the overall energy-saving strategy. In the first 12 months after the system
upgrade, Pilot Group EMS guaranteed Nottingham Textiles an additional saving of 15% on their existing system, but the upgrade installation actually exceeded this, saving the customer a total of 26.3% on the V16. This was a reduction of 152,927kWh, which equates to £4,444.96 saved or a staggering 26.2 tonnes of carbon prevented from being produced. By investing in the upgraded system,
Nottingham Textiles has been able to future proof its business for the next 15-20 years, using the latest EMS technology to manage its energy consumption.
A V16 Energy Management System was installed at Nottingham Textiles’s site in 2008 by the Vickers team,
guaranteeing a 25% reduction in their energy consumption. An upgrade ten years later by The Pilot Group, however, offered even more benefits for the company…
A
ble to trace its history back to the 19th Century lace trade, Nottingham Textiles
moved to a new factory in 2000 which would house a wide range of production machinery within the same building. A V16 Energy Management System was installed at the site in 2008 by the Vickers team, guaranteeing a 25% reduction in their energy consumption. However, after using the V16 system for
over a decade, the company had observed the benefits of using an EMS to control energy consumption within their operations. Then in May 2019, Nottingham Textiles was contacted by the now Pilot Group EMS team to discuss a potential upgrade to the system. Following advances in the technology of
the EMS, sensors with greater capability and accuracy were now available that could be used throughout the building. This was identified as a key benefit to a potential upgrade given the nature of manufacturing taking place at the factory. Temperature was a fundamental factor in production as the thread being produced could snap and potentially break a machine should conditions change quickly and temperature fall below a certain level.
THE SOLUTION The EMS team conducted a comprehensive site survey and put forward the option of an upgrade to a V42 EnergyMgr system. The modern sensors, accurate to 1.2 of a centigrade, would allow the system to eliminate more waste energy through greater precision and more accurately help safeguard against any

temperature changes that could impact operations. A pivotal upgrade to the
V42 system was the self- learning optimisation program which calculates the necessary burn time for each heater to reach the target temperature and establishes how much gas it needs to burn to reach the set level. External temperature sensors also work with built-in algorithms to process the outside temperature, calculating how long heaters should be running and automatically adjusting them when required. The V16 control panel was replaced with a
touchscreen, featuring enhanced functionality to offer more control and flexibility, and an inbuilt router for remote access with secure cloud-based technology. With this, it is possible to control the heating times from the panel and generate reports to manage usage as well as monitor live consumption, ensuring any spike in energy generates an alert so that issues can be investigated in real-time. The benefit of upgrading the system with the
same supplier is the existing knowledge of the previous system. Significant time was saved as Pilot Group EMS already understood the site and its operations, ensuring it was possible to
MAKING THE MOST OF THE SYSTEM Annual service agreements are invaluable in making the most of an energy management system. Nottingham Textiles secured an ASA to guarantee all technology upgrades are implemented by the Pilot Group team and ensure they are operating correctly. The site has seen significant further savings since the

implementation of the V42 system and has the potential to extend its capability to air conditioning and lighting control, as well as a metering function for gas and electric. Shayne Wilson, senior sales and
business development manager at Pilot Group, commented: “We are delighted to have implemented this system upgrade for Nottingham Textiles and enjoyed helping our client save more money and reduce their carbon footprint with the latest heating technologies.”
