Services BEAM, LEED and sustainable design Cundall was appointed as the BEAM, LEED and sustainability consultant for Phase 3, aiming to achieve one of Hong Kong’s first LEED v2009 Platinum rating and a HK BEAM Plus Platinum rating. The 'Back to Basic' design approach was adopted, incorporating cost effective and functional green building design concepts, stepping away from services overprovision using passive devices and avoiding over-complicated systems.The development aims to create a sustainable working environment, encouraging cultural change, with a 'green education programme' consisting of a guided tour including a smartphone app to showcase the building design, its features and its measured performance to influence visitors and tenants. The buildings' courtyard atriums allow for daylight diffusion as well as for natural cross-ventilation. Energy efficient envelopes for the buildings include: the insulated west façade, insulated green roof, optimised window areas, the highly insulated spandrel area and use of double-low-E glazing. The site boasts an extensive green landscape that covers 40% of the site. A weather-control low pressure drip irrigation system featured in the design, which should result in potable water efficiency.The masterplan and the buildings are thus designed to target best performance in: Energy - 30% reduction against EMSD typical office benchmark Water - 40% reduction in consumption against LEED baseline Effluent discharge - 50% reduction in effluent discharge against LEED Baseline Zero potable water for Irrigation – use of local and adaptive planting, irrigation supplied by efficient irrigation from collected rainwater (LEED - July Baseline) Outdoor quality – 40% planting of site area including soft landscape, water features and green roofs Material use – use 20% of recycled content, 20% regional material and 50% of timber to be FSC Waste – recycled 60% of construction waste, automatic refuse collection system provide for separation of paper waste Awards Hong Kong Green Building Award (2012), Building Project under Design, Grand Award winner
