Getting the temperature just right is a common point of contention in the office – and it can be all the more frustrating for building managers when the cost of heating and cooling a commercial site is so high.
Having struggled to stay comfortable in coworking spaces around the world, Matias Acosta and Sebastian Horstmann knew there was something wrong with existing commercial HVAC (heating, ventilation, and air conditioning) systems.
HVACs are set to a fixed temperature, which, according to Cosysense, means up to 80% of people will be uncomfortable, with women and minorities disproportionately affected. HVACs also consume large percentages of a commercial building’s power – making for huge utility bills – and contribute significantly to greenhouse gases.
These are the problems that led Acosta and Horstmann to found Cosysense. The startup’s patented climate control system is powered by AI agents, digital twins, and sensors that measure the building’s indoor environment, power usage, and emissions.
Cosysense also measures occupants’ sentiment by installing feedback panels that allow them to press a button to signify that they are too cold, comfortable, or too warm.
Fed by all of this information, Cosysense’s AI keeps the commercial buildings’ climate optimised, resulting in a comfortable working environment as well as cost savings and reduced carbon emissions. It also relays the data it collects in real-time on a dashboard that building managers can check out.
Cosysense has a few exciting client announcements in the pipeline, but a key achievement so far has been getting board approval to start trialling with a major fast food chain, initially covering 2,200 restaurants and growing by 200 restaurants per year.
Within the next five years, Acosta and Horstmann aim for Cosysense to have 6,000 clients across the US, UK, EU and Latin America (specifically Mexico, Brazil, and Argentina), acquiring 1% of the projected $8.1bn HVAC market. In 2026, things are heating up for this startup with no signs of cooling down.
