“We’ve been working with Cognition Controls for about a year and our office space is much more comfortable and easier to manage as a result. We had two areas that were always too hot or too cold. We used Cognition Controls’ historical data to troubleshoot what was happening, which led us to adjust the vents in one area. We also used their wireless sensors to better manage these spaces. Both are now as comfortable as the rest of our building – as evidenced by a significant reduction in complaints from the employees in those areas!”
