Abstract
Ljudje veliko časa preživimo v notranjem okolju. Kakovost zraka je za zdravje in dobro počutje bistvenega pomena. Za vzdrževanje kakovosti zraka je potrebno prezračevanje, kar pa je povezano s povečano rabo energije stavbe. Alternativo prezračevanju predstavlja filtriranje zraka. Razvoj živih sten in bioloških sistemov v notranjem okolju prodira tudi na področje filtracije zraka oziroma biofiltracije. Z namenom ugotavljanja vpliva takšnih sistemov na kakovost zraka v prostoru je bil izdelan prototip aktivnega biofiltra zraka. Z vključitvijo prototipa v zasnovano merilno progo nam je pri normalnih sobnih pogojih uspelo znižati koncentracijo CO2 v zraku za 13,78 %, pri meritvah s povišano začetno koncentracijo CO2 pa za 14,89 %. Koncentracije prašnih delcev PM10 smo znižali za 29,37 %, PM2,5 za 29, 37 % in PM1 za 33, 33 %.

Title:Impact of active biofilter on indoor air quality
Abstract:
As people spend most of their time indoors, indoor air quality is essential for their health and well-being. To maintain sufficient indoor air quality, we need to ventilate the indoor environment, which requires additional energy. Alternatively, the air can be filtered to reduce the need for ventilation. The development of green living walls and other bio systems in the indoor environment is making the use of indoor air biofiltration possible. We have built a working biofilter prototype and used it to measure the impact of these systems on the indoor air quality. In the controlled volume that we have set up, we were able to measure 13.78% lower concentration of CO2 in conditions with normal indoor air quality, while measurements with a higher starting CO2 concentration showed a reduction by 14.89%. A reduction in the concentration of airborne dust particles was also measured; the PM10 dust particles were reduced by 29.37 %, PM2.5 by 29.37% and PM1 by 33.33%.
