Poor air quality at university? Lufft’s products ensure perfect room climate

Considering that we spend no less than two thirds of our lives in enclosed spaces, the quality of indoor air plays a crucial role for our health and our well-being. The indoor climate is a major factor influencing our physical and spiritual condition. This makes it all the more important to strive for an excellent room climate, especially in offices, classrooms and lecture halls – i.e. in places, where many people gather.

Four factors play a key role here: air temperature, the temperature of surrounding areas, air humidity and airflow inside the room. It is generally accepted that the optimum air temperature in closed premises should be between 19 °C and 22 °C and that air humidity should be within the range between 40 and 60 percent. In most rooms, however, the temperature is too high while the air humidity is too low. Excessively low air humidity causes headaches, fatigue, reduced concentration and may dry the mucus membranes. The latter effect makes bacteria and viruses spread faster and this in turn leads to diseases. On the other hand, excessively high air humidity is generally perceived as part of a “sweltering” climate – this condition often arises if the ventilation is insufficient.

Regular ventilation can decisively influence and improve the room climate. It not only balances out oxygen content in the air, but also increases airflow inside the room. By breathing, we take in oxygen and release moisture and carbon dioxide. We often feel tired and have trouble concentrating whenever the CO2 content of the air gets too high. Another way of balancing out our room climate is by using plants. The most suitable plants for this purpose are those with large leaf surfaces, such as banana trees, vines and ivy. In the course of photosynthesis, plants convert carbon dioxide into oxygen. Regular ventilation offers one further advantage: it can significantly reduce the formation of mold, because the spores only have a chance to reproduce if there is a sufficient build-up of moisture inside the room.

Lufft data logger OPUS20 TCO

Lufft made it easy to monitor room climate by developing the OPUS20 TCO. The data logger measures the indoor temperature, the air humidity and the CO2 concentration. This data can be retrieved directly via a LAN connection, which lets you spot every change instantaneously. The applicable guideline for classrooms in the USA calls for a maximum threshold value of 1000 ppm (parts per million), whereas the required MWC (Maximum Workplace Concentration) value for workplaces is set at 5000 ppm. Additional sensors can be installed in larger rooms. This makes it possible to adjust the automated ventilation systems in buildings with a high degree of precision without opening any windows. Thanks to its compact dimensions and battery operation, the OPUS20 TCO is easy to install on any wall. The OPUS20 THI provides data on the indoor temperature and relative humidity for the industrial monitoring of room climate. With this device, Lufft now offers the perfect tool for the monitoring of data centers, switch cabinets, wind turbines, storage rooms and museums.

    Dear Tifany,

    We are glad to help you understanding the reason for tiredness in lecture halls better – it’s not always because you hadn’t enough sleep ;-). If you feel tired next time, maybe you should go out and get some fresh air or open a window. Hope it helps!

    Warm regards,
    Helena
