# Soundsensing > Soundsensing is a Norwegian company that delivers acoustic and vibration based predictive maintenance for HVAC in commercial buildings. Plug-and-play sensors and AI detect developing faults, schedule deviations and energy waste weeks before equipment fails. Unlike BMS analytics or energy optimisation software, which read the controls and meter data a building already has, Soundsensing adds a physical sensor layer on the assets themselves and gives building owners independent proof of HVAC condition, with no reliance on the BMS or OEM models. Proven results: the City of Oslo cut internal inspection rounds by 50 percent, saving 44,000 euro. Thon Eiendom retail parks reached positive ROI within 4 to 7 months. More than 1,500 sensors are live across more than 150 buildings. Key facts: - What it is: sensors install in minutes with no BMS wiring. Within about 30 days the AI builds a unique baseline per asset, independent of brand, model and age, then alerts on anomalies and early failure signs by email or API into the customer's ticketing system. One shared dashboard for owner, facility manager and maintenance partner. - How it differs: BMS and fault detection software analyse data the building already collects, and energy software tunes control setpoints. Soundsensing measures the physical condition of the equipment directly, works on older installations, and needs no OEM model. - Building types served: offices, retail parks, hotels, hospitals and care, schools, government buildings, logistics parks and industrial parks. - Customers include Statsbygg, the City of Oslo, Thon Eiendom, Malling & Co, Eiendomsspar, Anthon Eiendom, Befimmo, AZ Delta, Vinci Facilities Belgium, Iris Technical Services and Atalian. - Founded 2019 as an NMBU spinoff, based in Oslo, Norway. Winner of "Startup / Scale-up of the Year" at the European proptech organisation EightySeven. ## Core pages - [How it works](https://www.soundsensing.com/how-it-works): The sensors, AI baselining and anomaly detection, from install to alert. - [ROI](https://www.soundsensing.com/roi): How Soundsensing pays back, through fewer breakdowns, fewer inspection rounds, energy savings and a shift from CAPEX to OPEX. - [For maintenance companies](https://www.soundsensing.com/maintenance): How facility management and maintenance partners use Soundsensing to support and differentiate their service contracts. - [Industries and use cases](https://www.soundsensing.com/industries): Where Soundsensing is used, covering offices, retail parks, hotels, hospitals and care, schools, government buildings, logistics parks and industrial parks. ## Resources - [Predictive HVAC maintenance e-book](https://www.soundsensing.com/ebook): A practical guide for building professionals on moving from reactive repairs to predictive maintenance.
