“…The studies have reported that green roofs can reduce summer daily peak surface temperature by 15 °C-45 °C and peak air temperature by up to 5 °C. Energy demand can be cut by 8%-80% for individual buildings, depending on background climatic conditions and roof insulation levels [35]. When applied on a city scale, green roofs may reduce the ambient temperature between 0.3 °C-3 °C [36].…”

Most studies explored green-roof thermal effects on a few hot summer days based on short-term monitoring data. Few studies investigated the seasonal and diurnal patterns of thermal performance and associated weather effects. This research aims to address the following two questions: (1) how green-roof thermal performance varies with different season and time; and (2) to what extent can thermal performance be predicted by background weather parameters? A retrofitted extensive green roof was established on the top of a railway station in subtropical Hong Kong. Monitoring data covering a two-year period, one year before roof greening and one year after, were collected and analyzed. Results indicated notable seasonal and diurnal patterns of green-roof thermal performance. It exhibited cooling effects in spring, summer and fall, but warming effects in winter. The cooling effects were more pronounced in summer than spring and fall, on sunny days than rainy and cloudy days, and in nighttime than daytime. Air temperature, relative humidity, wind speed, solar radiation, and soil moisture could explain 83.6%-86% of the thermal effects' variation. The multiple-regression models based on the five weather variables established in this study provide an uncomplicated and direct approach to predict the thermal performance of similar extensive green roofs in subtropical areas.

“…In this circumstance, the practice of the indoor greening system alone or in combination with conventional ACMV systems in buildings may provide environmental value and in addition contribute to reduce energy consumption [8]. By employing a greening system in the interior building, the effect on indoor air temperature and humidity are significant [9].…”

Abstract. Indoor environmental quality (IEQ) objective generally focus on providing energizing and comfortable environments for occupants and minimizing the risk of building-related health problems. Living green walls are natural air-filters that creates a cleaner and revitalizing work environment that will lead to better IEQ. The research presented here describes the design (the new concept) of the botanical indoor air biofilter (BIAB) and modelling conducted to determine the effectiveness of the system in reducing the indoor airborne particulate matter levels. The BIAB was also evaluated for its single-pass filtration for particles ranging in diameter from 2.5 to 10 µm along with total suspended particles. The system is comprised of three functional components; a region of vertically grown plants as botanical section, an evaporative cooling pad as cooling section (additional section from a commercial BIAB), and a mechanical ventilation system that supply cool filtered air to surrounding. The complete system recorded highest removal efficiencies of 85% for TSP, 75.2% for PM2.5, and 71.9% for PM10. It indicated that with the additional component in the BIAB system (cooling component), it provides enhancement of the particulate removal due to the ability in absorbing the dust particles and filtration dynamics as the polluted air pass through the wetted cooling pad and the light shower of water.

The awareness of the heavy impact that the building sector exerts on the natural environment is now widely shared, leading to a wide spread of tools (rules, regulations, voluntary rating) to control and guide towards building environmental sustainability. In this shared vision, the natural environment is perceived essentially as an asset to protect. But nature is not just something to be protected, it is also a key factor to improve the quality of our built environment and our well-being. Numerous studies analyze the positive impact of the introduction of natural elements in building design (i.e. green walls, indoor green, aquatic elements, etc.), including: reduced energy consumption, improved IAQ, benefits on users' attention capacity in office settings, stress-reducing effects in healthcare environments. However, despite this evidence, the use of natural elements in common building practice is still not quite widespread. There is therefore a need to promote awareness and use of the potential of the natural elements in design. This paper aims to assess and promote the enhancement of the natural elements in the voluntary green rating systems, as active tools in promoting environmental sustainability to all the actors of the building process. To this end, the study was developed through the following steps: 1. in the literature, identification of the elements of nature-based design with more evidence on environmental performance; 2. in green rating systems, identification of the weight given to the natural elements, evaluation of their current level of enhancement within the systems and identification of possible areas of development.
