An Experimental Study of Indoor Air Quality Enhancement Using Breathing Walls

Recently, many studies have focused on studying indoor air quality, especially with the outbreak of COVID-19, which is one reasons for increased need to improve quality. Many ideas and applications are available incorporate nature into buildings quality (IAQ) thus secure a higher percentage natural ventilation pollution reduction. One these use "breathing walls" (BWs), envelope components based porous materials. They decrease energy consumed heating, ventilation, air-conditioning buildings. The study discusses effect using BW approach thermal comfort in Moreover, improvement IAQ when two models - BWs (applying industrial materials together BWs, composed wooden concrete hollow bricks (WCHBs)), other model built solid traditional (STB) was studied through an experiment compare temperature, carbon dioxide (CO2) concentration, relative humidity behavior. experiments were conducted five months summer 2019, results both compared. From results, it may be concluded that exhibits improved behavior than by recording average three degrees lower outside temperature. WCHB STB ~41.66% same conditions; however, CO2 concentration (ppm) ~28.5% conditions.
