Fexillon

Fexillon, formerly Integrated Facilities Solutions, makes a platform for owner-operators of buildings and infrastructure. It collects and checks asset information from the strategy stage through design, construction and handover, ending with an approved digital building record for operations teams. The core platform uses a six-stage framework and a Digital Plan of Work that ties information delivery to roles and assets. The aim is a single trusted asset record and consistent asset tagging. Fexillon Twin extends the platform. It runs on Microsoft Azure Digital Twins and combines BIM, IoT sensor and building management system data in one model. Twin modules cover space occupancy, indoor air quality, energy, water, asset data and AI-assisted custom analytics. The air-quality part is a RESET-accredited data provider, and projects such as Microsoft Dublin and the JE Dunn headquarters in Atlanta use it. Alongside the software, Fexillon sells information management and operational readiness services for the move from construction to operations. Its main markets are healthcare, data centres, education and residential portfolios, and its client logos include Microsoft, CBRE, Kier, Balfour Beatty and Irish Rail. Pricing is not published, and buyers have to contact sales. The main limitation is that there is very little independent review evidence or public technical documentation. The platform is also aimed at buildings rather than heavy industrial plants, so it does not cover maintenance execution such as work orders.
