Our Story

LightFi’s vision is to make old buildings into smart buildings  that cater to our wellbeing while being energy efficient at the same time. Retrofitting workplaces, especially to reduce energy use, often fall to the bottom of the to-do list of landlords and tenants. It is notoriously complicated to upgrade building systems: not only does it cost a lot of man-hours and capital to install, rewire and reprogram, but it's also disruptive, with office downtime and the end result doesn't benefit the users. LightFi changes all this. We created a smart building automation retrofit solution that enables responsive HVAC and lighting to give you a more comfortable and healthier working environment.

Through WiFi based, IoT technology our customers know  how, where and when people are using the building in real time. Through integration this enables demand based HVAC automation that is responsive to what is actually happening in the room. This way your building provides a comfortable working environment that caters to your wellbeing, while saving energy in the background. It’s a true retrofit solution, no rewiring, no hand-waving, no monkey business.
