Theme B: Creating a livable, healthy and environmentally viable citiesin between these platforms, every opportunity has been sought to maximize greencoverage on the inclined surface. Slope greening using hydro-seeding on soilslope has been adopted comprehensively through out the site. Hard surface suchas retaining walls are softened by creepers, colour treatment and introduction ofplanters. More innovative solutions of bio-engineering planting such as hydromulching system have been adopted to sustain round-the-year plant growth on thedry, rocky surface originally not suitable for plant growth.5. LONG LIFE LOOSE FIT GREEN TECHNOLOGYInnovative concepts are underpinned by the enabling force of technology. Theconcept of long life, loose fit vertical green panels in the form of thin claddings isdeveloped jointly with the contractor and applied in EHC Site Phases 4 and 5.Recognising that truncated pocket greening at the ground level could not bereconciled by roof greening at 30-40stories above ground, the solution tomeaningfully increase greening percentage for pedestrian comfort is to extend ongradegreening to the vertical dimension.The vertical green panels compose of 1000 x 500mm aluminium trays with 40mmthick proprietary product l as the growing media. Plant Species commonly used inHA projects, such as Parthenocissus himalayana, Zephyranthes grandiflora,Lantana montevidensis, Nephrolepis exaltata, etc, are selected for trial. Tofacilitate ease of operation, networks of automatic irrigation pipes have beenintroduced to form an integral part of the system. Trial panels have been set up toexplore various possibilities of optimizing the design. They have been installed atthe roof top of the site office to serve as green roof during construction stage. Atotal of around 240 nos. of the panels will be permanently erected at EHC Phase 4.Some of these green panels will be installed at the vertical walls of lift tower androck slopes, others will be installed at roof areas with limited loading allowance.189
