jailcd2020077: The Influence of Active Living Wall on Indoor Temperature and Humidity Conditions in the Coastal City of Oingdao in Winter

Abstract

Living walls are systems that take into account the development of flora in a vertical surface attached to building facades or indoor walls. Traditionally, they have behaved as 'passive’ bio-filters, but new approaches and engineering sciences are going towards their integration within the building's air conditioning and ventilation systems. In an Active Living Wall (ALW), air is forced to go through the vegetated wall to acquire vantage of their evaporative cooling potential as well as the capability of these biological systems to purge air. In the case of indoor ALWs, air is cooled, bio-filtered and humidified thus potentially reducing ventilation requirements. This work describes a prototype indoor ALWs installed at the Qingdao University of Technology. Preliminary effects of its public presentation of indoor air conditions (temperature and humidity) are shown and talked about. The average air temperature of the room with active living wall was 1.9-2oC lower than another room without it, while the average relative humidity of the room with active living wall was 3.4-4.1%higher than the other. Preliminary research results show that ALW is effective for cooling process and humidification of central heating room in winter in the coastal city of Oingdao.
