Precise measurement data increases building performance

Around 40 % of the global final-energy requirement is used in buildings. Many air-conditioning and ventilation systems in public and commercial buildings are not optimally adjusted, contain outdated components or are oversized and are responsible for up to 50 % of energy costs.

In order to save energy, buildings today are almost hermetically sealed. The air quality can quickly reach values that impair the well-being and performance of people and can even lead to health problems in the long term.

Precise measurement data creates the basis for both energy and cost-efficient control of the ventilation and air-conditioning systems and, in this way, ensures a healthy indoor climate and satisfied building users.

The smart sensing portfolio from WIKA ensures continuous and precise recording of pressure, temperature, humidity and air quality. Analogue and digital signal transmissions as well as LoRa®WAN radio solutions enable problem-free integration into any automation and control system as well as into cloud environments. In this way, you can also make existing systems fit for the future with retrofit solutions.
