Poor concentration and reduced learning capacity in schools and educational institutions is a frequent problem. And no wonder: up to 30 pupils in one classroom require a high quantity of fresh air to ensure a healthy room climate. But in practice this can’t be achieved with mechanical (window) airing during the brief breaktime airing periods. Too much CO2, fine dust or vapours emanating from building materials and furniture result in a muggy atmosphere within minutes.
However, fresh air not only helps concentration but also costs a lot of energy: with conventional window airing, heat escapes to the outside, and after airing the cooled room air has to be warmed up again by the heating system. It also makes effective airing more difficult: energy-saving windows, safety aspects and outside noise or pollen counts are just some of the factors in play. It means that airing is restricted to periods that are too short for sufficient air exchange. The CO2 concentration therefore quickly passes 2000 ppm – a value at which German environmental agency recommendations require more extensive organisational, ventilation-related or structural measures.
LTG air/water systems have devised for these applications to ensure fresh air while saving energy. Moreover, convenient and efficient LTG air diffusers and high-precision LTG components for air distribution are also used to achieve an effective air change and optimum air supply to the rooms.
