In Hong Kong, extremely high land price drives design for the absolute maximum in profitability from the developer?s perspective. The efficiency rate of the property, which means the ratio of saleable area to gross floor area, is the pre-dominating grading index in the property industry.

Higher efficiency the layout, more competence the architect is. Somehow, individual owners do agree on this only index and have little concern on physical liveability. Sustainability is somehow perceived as a trendy fashion, and even a good-to-have or optional item.

How can we stand on the frontier to bargain yet not compromise liveability & sustainability against efficiency & profitability in design of all buildings not just green architecture?

Design wants no limitation. To a certain extent, however, some government restrictions give bargaining power to architects to fight for more green against efficiency & profitability. Once liveability and sustainability is a mandate, there is more room for green movement.

Enjoyable green, abundant daylight and naturally-ventilated air are essential for health and well-being. Such provisions shall be pre-requisite rather than marginalized in high-density high-rise built environment or gimmicky in green buildings. The next frontier of green architecture shall be advocated, including a new set of Practice Notes for Architects' Pre-emption (PNA’P) - Advocacy (ADV).

Link Chairs: “PNA’P ADV076 - Sky Gardens for Co-living” The higher the building, the more the liveable green spaces at high levels. Daily urban living shall be extended to outdoor and neighbour sharing spaces for nature and social interactions.

Link Chairs: “PNA’P ADV099 - Light and Air for Biotope” Design paradigm shifts from mitigating urban adversity to regenerating the natural environment by revealing sky views with light and air and fostering the positive impact on flora and fauna.

聯繫自然與城市生活需要一個選擇嗎？居所離地面越高，與自然和社區的聯繫就越疏離，越需要充滿綠色、陽光、涼風，與家人和鄰居互動的宜居環境。這是高密建築之基本，人與自然與生俱來互動聯繫之延續，我們要堅守。
