Sensor technology revolutionises indoor climate optimisation
Empa researchers are using innovative sensor technology and mathematical models to investigate smart solutions for optimising the indoor climate. The aim is to improve well-being in the workplace and at the same time utilise energy more efficiently.
While heatwaves are a nuisance, many companies are looking for solutions to make the room temperature in offices and workspaces comfortable and energy-efficient. Empa researcher Agnes Psikuta is focussing on advanced sensor technology. Her “smart dummies” called ANDI and HVAC, equipped with a large number of sensors, analyse the indoor climate in real time and help to bring workplaces to a comfortable temperature in the long term.
The intelligent HVAC dummy measures the air temperature, humidity and air movement in offices in detail and analyses heat sources in order to better understand the interaction between heating, cooling and air circulation. ANDI, on the other hand, records the entire heat balance of a typical person under these conditions. These measurements make it possible to air-condition buildings more efficiently without sacrificing comfort.
Optimisation potential for offices and operating theatres
The data collected should not only help to reduce energy requirements in offices, but also contribute to improving climatic conditions in operating theatres. The precise measurements by HVAC and ANDI support the ideal positioning of heat lamps to protect patients from hypothermia without overheating the operating theatre team.
