Assessing the impacts of living moss panels on the quality of indoor classrooms

Project Details


The nature of the learning environment has a direct impact on how well children learn at school. Studies show inadequate temperature control, air quality and acoustics have detrimental effects on children and teachers - on concentration, mood, well-being, attendance, and ultimately, attainment (Higgins et al., 2005). Providing the appropriate conditions in a classroom is not only important for learning attainment but needs to be done in such a way that limits energy consumption, thereby reducing bills and minimising CO2 emissions. As many schools are situated near busy roads, such conditions also need to be delivered in a way that limits the effects of pollution. In a post COVID 19 world, understanding the ingress of pollutants is especially important as the transmissibility of viruses is linked to particular pollutant types often found in urban environments (Harvard University, 2023).

Like living walls, moss walls create a comfortable, welcoming atmosphere to reduce stress, elevate moods, and improve concentration. Moss also provides an additional air filtration system, taking in pollutants while producing oxygen. Moss offers a cheaper alternative to other forms of living walls and do not require costly ongoing maintenance, regular plant replacement, or pesticides (Archdaily, 2019). However, the use of living moss walls (LMWs) as an alternative has not been explored in schools.

This project investigates the impacts of living moss walls in a classroom of an existing school. The analysis will be based on a parametric evaluation of the impact the LMWs could have on thermal and air quality characteristics of classrooms. Indoor temperature, humidity and VOCs as well as outdoor temperature and humidity will be monitored regularly. Particulate matter in the classrooms and immediately outside will be periodically monitored. Finally, schoolchildren’s views will be gathered regarding the impacts of the moss panels on their wellbeing.
