Sontay has supplied sensors and measurement devices for the new Incity Tower in Lyon, France. They are combined with products from Distech Controls. This office building peaks at 200 m and is the first large-scale building (40 000 m2) to achieve HQE (High Environmental Quality) certification in a city centre in France and also has a BREEAM ‘Excellent’ rating. It is the tallest tower in Lyon and the third tallest in France.
Working with Distech Controls, Sontay provided 240 carbon-dioxide sensors, which were installed by a local systems integrator. These sensors use a non-dispersive infra-red sensor to measure carbon-dioxide concentration. They have a self-calibration algorithm to improve long-term stability and accuracy.
