Description of vertical greenery systems in HortPark with Summary of average wall surface temperatures on 28 Apr 08 (Pérez et al. 2014; Wong et al. 2010)
| S.No | System typology | Description | Maximum reduction of average wall surface temperature (ºC) |
|---|---|---|---|
| 1 | Living wall – Modular panel, vertical interface, mixed substrate | Combination of 2 systems: the versicell-based and ‘plug-in’ slot planter system. Versicell planters have drainage cells with selected mixture of green roof and soil planting media wrapped in geo- textile membrane while the slotted planters are mainly planter cages system | 10.03 |
| 2 | Green façade – Modular trellis | Climber plants in planters forming green screens across mesh panels on the wall | 3.33 |
| 3 | Living wall – Grid and modular, vertical interface, mixed substrate | Plant panels embedded within stainless steel mesh panels inserted into fitting frames | 11.58 |
| 4 | Living wall – Modular panel, vertical interface, inorganic substrate | Employed the Parabienta system with a patented growing medium (composite peat moss) as a planting media inlay. The peat moss panel encased in a stainless-steel cage is hung onto supports lined with integrated irrigation | 10.94 |
| 5 | Living wall – Planter panel, angled interface, green roof substrate | This system uses a UV-treated plastic as a molded base panel with integrated horizontal planting bays | 10.03 |
| 6 | Living wall – Framed mini planters, horizontal interface, soil substrate | Individual mini planters placed and secured onto stainless steel frame | 6.85 |
| 7 | Living wall – Vertical moss-tile, vertical interface, inorganic substrate | Patented ceramic tiles shipped with pre-grown moss species. Suitable for creating tiling designs | - |
| 7a | Living wall – Flexible mat tapestry, horizontal interface, soil substrate | Lightweight panel comprising 2 layers of moisture retention mats secured onto a supporting grating or mesh. Plants slotted and pre-grown in between mats. Suitable for flat and curved surfaces. Allows ease of change | 6.58 |
| 8 | Living wall – Plant cassette, horizontal interface, soil substrate | Use of planters to hold wider variety of plant types and of larger sizes. Planters are secured onto the wall through hinges. Lightweight growing medium is used | 9.27 |
