Honeywell has worked in building controls for more than a century, growing from early thermostat control into one of the world's largest building technology businesses. Through Tridium, the company behind the open Niagara Framework, it also underpins many of the multi-vendor BMS integrations found in UK commercial buildings. Honeywell also owns Trend, which is listed separately.
Honeywell position themselves as a single source for building automation, from field devices and controllers through to supervisory software and analytics. Their BMS controls heating, ventilation, air conditioning and lighting, and connects with fire, security and access systems, with cloud tools for monitoring performance across a portfolio.
Honeywell suits owners and asset managers of larger buildings and portfolios who want a long-established vendor with a broad product range and a large UK integrator network behind it.
