Our building energy management system monitors, controls and improves how your building uses energy — cutting costs, boosting efficiency and supporting Net Zero goals.
Today, many companies are facing challenges due to rising energy costs, inefficiencies, and outdated building systems.
ista’s building energy management system (BEMS) is an integrated platform that monitors, controls and optimises your building’s energy performance — from HVAC to lighting to ventilation. With real-time insights, automated controls and predictive analytics, you can reduce energy waste, cut costs and improve occupant comfort, all while supporting your net zero and ESG goals.
The system collects data from sensors and IoT devices, responding dynamically to usage patterns, automating asset control and visualising performance in user-friendly dashboards. Seamlessly integrating with existing building systems, renewable sources and the smart grid, it is a future-ready solution for energy-conscious businesses.
When a Building Energy Management System is installed, sensors, controllers and software components are set up to monitor and manage your building's core systems, including the heating, ventilation and air conditioning (HVAC) system, and the lighting system. These devices collect real-time performance data and automatically adjust system outputs based on factors such as occupancy, schedules, weather conditions and energy tariffs.
This data is fed into central dashboards, providing facility teams and energy managers with instant access to valuable insights. This allows you to identify inefficiencies, compare performance across sites and respond quickly to anomalies, or simply let the system optimise itself in the background.
Unlock the full potential of your property’s efficiency and savings with ista’s BMS.
With years of experience and a deep understanding of energy billing requirements, we set the industry standard for precision, reliability, and innovation.
Our energy management solution delivers more than real-time data; it’s a high-performance system that actively improves your building's energy efficiency. Thanks to automated HVAC and lighting control, AI-driven optimisation and flexible scheduling, you can fine-tune performance without manual oversight.
Open protocols such as BACnet and Modbus ensure seamless integration with your existing infrastructure, and compatibility with tools such as ista MinuteView makes data analysis straightforward and actionable. Cloud-based dashboards and automated reporting provide your team with easy access to performance insights anytime.
Our BEMS is designed to meet UK and EU compliance standards, including GDPR and EPBD readiness. It also integrates with renewable energy sources and supports grid flexibility. Whether you are managing one site or an entire portfolio, you will benefit from a scalable solution that is ready for today and tomorrow.
A Building Energy Management System or BEMS is an integrated hardware and software solution that monitors, controls and optimises a building’s energy-consuming systems. Through a centralised digital platform, it enables businesses to reduce energy waste, improve performance and meet sustainability targets.
Sensors and controllers installed throughout the building collect real-time data from systems such as HVAC, lighting and ventilation. The BEMS software processes this data, automating control actions, visualising performance trends and enabling predictive optimisation. All of this is accessible via cloud-based dashboards.
A BEMS can manage a wide range of systems, including Heating, Ventilation and Air Conditioning (HVAC), lighting, hot water, air quality systems, and even energy storage or on-site renewables. It ensures that these systems operate efficiently and respond dynamically to changing conditions.
A BEMS system can help businesses to reduce energy consumption and costs, improve occupant comfort and gain full visibility of building performance. It also simplifies compliance with ESG and Net Zero targets and delivers a strong return on investment through automation and data-driven control.
A BEMS collects real-time data from sensors and controllers across HVAC, lighting, ventilation and other systems. This data can then be used for monitoring, performance benchmarking, predictive control and automated reporting, helping businesses to make informed decisions and reduce energy waste.
ista’s BEMS meets strict UK and EU data protection standards, including full GDPR compliance. All data is securely encrypted during transmission and storage, and role-based access controls ensure that only authorised users can view or manage it.
Yes. ista’s BEMS is designed to work in both new and existing buildings. With flexible hardware options and support for open protocols like BACnet and Modbus, it can be integrated into legacy systems or retrofitted with minimal disruption.
Yes. ista’s BEMS supports open protocols such as BACnet and Modbus, enabling smooth integration with most existing building management systems, legacy infrastructure and third-party platforms.
Our solution is fully scalable, from a single site to a complex portfolio of buildings. ista’s cloud-based platform provides centralised visibility and control across all locations, enabling consistent optimisation and portfolio-wide reporting.
Yes. A BEMS can support compliance with the Energy Performance of Buildings Directive (EPBD) and other national regulations by providing transparent and verifiable data on a building's energy use, the efficiency of its systems, and the efforts made to optimise them. It also helps organisations meet UK Net Zero and ESG reporting standards.
Automated energy management provides the real-time data and control necessary for tracking and reducing energy-related emissions. It enables continuous optimisation and identifies efficiency opportunities, ensuring that sustainability goals are backed by measurable, verifiable performance data.
The return on investment depends on the size of your building, the complexity of your system and your energy profile. Many businesses achieve measurable savings within 12–36 months thanks to reduced energy costs, improved operational efficiency, and streamlined reporting.
