Siemsatec was engaged to deliver the Building Management System (BMS) for the Willowfield building at King’s College Hospital (KCH). This project marked the first fully electrified building on the campus, relying solely on air-source heat pumps (ASHP) for heating and a Mitsubishi QTon system for Domestic Hot Water Supply (DHWS) throughout.

A Trend BMS was installed, with Siemsatec working closely alongside the mechanical and electrical (M&E) contractor, TClarke, to deliver the project on time and within budget. As a design-and-build installation, the project required close collaboration from the delivery team.

The commissioning team ensured the building was fully operational at handover, meeting rigorous timelines while implementing advanced BMS technology to manage the building efficiently

Siemsatec case studies.

In 2023, Siemsatec upgraded The Royal Society of Science’s BMS from legacy IQ2 and 963 systems to the advanced IQ4 and IQVision platforms. This modernization improved operational efficiency, enhanced building management capabilities, and reinforced the long-standing 15-year partnership between Siemsatec and the society.

Siemsatec has provided 7 years of exemplary BMS service to the South London and Maudsley (SLaM) Trust, earning the renewal of its maintenance contract. Their customer-focused approach, 24/7 emergency support, and expertise in secure healthcare environments ensure patient safety, regulatory compliance, and reliable system operation.

Siemsatec upgraded the historic Tea Trade Wharf BMS by replacing outdated IQ2 controllers with modern IQ5 units, integrating T1L network capabilities and a bespoke IQVision supervisor. The project improved energy management, plant control, and sustainability, all while minimizing disruption to residents and optimizing costs.

Siemsatec completed a three-year BMS upgrade across Battersea Cats & Dogs Home’s London, Old Windsor, and Brands Hatch sites, improving animal welfare, energy efficiency, and real-time data management through the Trend IQVision platform. The phased, budget-conscious approach ensured minimal disruption while delivering measurable operational and environmental benefits.
