“…The indoor level of relative humidity decreased (48%) and the air temperature (26.3°C) and CO 2 concentration (1125 mg•m −3 ) were constant in the classrooms with indoor plants. Previous researchers have reported that indoor plant placement can regulate air temperature and relative humidity in indoor spaces through evapotranspiration (Davis and Hirmer, 2015;Mangone and van der Linden, 2014;Moya et al, 2018;Qin et al, 2014). Other previous studies pointed out that a classroom is a unique space because of its overpopulation of students (Becker et al, 2007) and the increased indoor level of CO 2 mainly by the metabolic processes of indoor occupants (Cetin and Sevik, 2016).…”

This research evaluated the attention capacity of 70 pupils in the sixth grade with the intervention of indoor air quality regulated by indoor plant placement in the classrooms of two elementary schools in Seoul, South Korea. Two sets of three-week measurements were conducted with an interval of 12 weeks from 27th June to 7th October, 2016. We divided subjects into two groups (Group I and II): subjects in Group I occupied classrooms without indoor plants and those in Group II occupied classrooms with indoor plants. The classrooms with indoor plants had indoor levels with constant air temperature (approximately 26°C), relative humidity (around 50%), and carbon dioxide (CO 2) (around 1100 mg•m −3). Additionally, 12-week placement of indoor plants reduced the indoor concentrations of airborne contaminants. After 12 weeks of the experiments, the subjects' attention capacity improved as demonstrated by a standard questionnaire (Frankfurt Aufmerksamkeits-Invertar, FAIR). Indoor plant placement showed little difference in terms of efficiency (FAIR-E) and continuity (FAIR-C) scores, but exhibited a significant improvement for performance (FAIR-P) (increasing from 0.964 to 0.989) and quality (FAIR-Q) scores (increasing from 0.945 to 0.973). Based on multiple regression, the current study suggested that indoor plant placement was one of the most important factors to improve the attention capacity of pupils in classrooms.

“…Based on the growing medium, indoor plants are generally grouped into soil-based, non-soil based (such as hydroponic [96], aeroponic, or aquaponic [97]). In additional to conventional indoor potted plants, innovative indoor vertical greenery has also been investigated [37,98]. However, there is still a need to explore how indoor planting can be integrated into building services design.…”

Characterisation of Nature-Based Solutions for the Built Environment

2017

Nature has provided humankind with food, fuel, and shelter throughout evolutionary history. However, in contemporary cities, many natural landscapes have become degraded and replaced with impermeable hard surfaces (e.g., roads, paving, car parks and buildings). The reversal of this trend is dynamic, complex and still in its infancy. There are many facets of urban greening initiatives involving multiple benefits, sensitivities and limitations. The aim of this paper is to develop a characterisation method of nature based solutions for designing and retrofitting in the built environment, and to facilitate knowledge transfer between disciplines and for design optimisation. Based on a review of the literature across disciplines, key characteristics could be organised into four groups: policy and community initiatives, multiple benefits assessment, topology, and design options. Challenges and opportunities for developing a characterisation framework to improve the use of nature based solutions in the built environment are discussed.

a b s t r a c tThe evaporative-cooling roof is a popular passive energy conservation technique. This article presents a novel approach for modelling and analysing the influence of evaporation on roof thermal performance. A multivariate nonlinear model was developed for the prediction of the evaporation rate from porous tile. A computer program was then developed based on the one-dimensional roof unsteady heat transfer theory. Finally, the computer program and hourly weather data of Guangzhou, China, were used to analyse the impacts of evaporation (including the evaporation start time and water-application frequency) and slope orientation on roof thermal performance. Evaporation beginning at 11:00 can reduce the external surface temperatures of a horizontal roof and 30 • -inclined east-sloping and west-sloping roofs by up to 11.3, 10.7, and 9.8 • C, respectively, from those of a non-evaporative roof. This, in turn, can reduce the peak-hour (16:00-20:00) internal surface heat flux. Additionally, with the horizontal roof, the reduction in the peak-hour heat flux can be doubled if the evaporative layer is frequently replenished with water.
