Wireless sensors fit the bill

Sontay’s SonNet wireless sensor system is regulating temperature and improving comfort levels for occupants at the renovated No. 1 Kingsway, Aldwych London. Completely rebuilt behind the original 1920 Portland Stone facades, the stunning building features 105,000sq ft of Grade A sustainable office space as well seven high-specification residential apartments.


Achieving a BREEAM rating of Excellent, No. 1 Kingsway is located in central London at the junction of Aldwych and Kingsway and houses The Delaunay restaurant, sister to the renowned Wolseley in Piccadilly. Keeping the original aspects of the building meant that a wireless system was the ideal choice. The main contractor on the project was ISG and Matrix, a nationwide controls company, commissioned and installed the Sontay SonNet system.

Peter Ball, Commissioning Engineer at Matrix comments: “We needed to create a flexible and energy efficient HVAC system and, because we could not re-wire the whole space, we needed a reliable and robust wireless system. We have worked with Sontay before and knew about the SonNet system. It was perfect for this application and with the help of the Sontay team we were able to commission and install the wireless system with no problems.”


Following a detailed site survey, fully supported by Sontay’s field representative, Matrix were able to prove that the equipment would work correctly, prior to installation. Throughout the project there are 29 routers and eight receivers as well as the 276 sensors. Each sensor measures internal temperature of the building, helping to regulate the HVAC services for optimum efficiency.


Installation was quick and easy. Since sensor operation is based on the latest 2.4 GHz licence free radio technology, specifying SonNet sensors eliminated the need for Matrix to run any structured cabling to the products.
