In order to promote multi-level greening, Urban Renewal Authority
(URA) has appointed a multi-discipinary study team led by Architecture
Design and Research Group Limited (AD+RG) in October 2006 to
review the best practices of vertical greening design and to formulate
standards and guidelines for future reference with regard to existing
local building regulations, codes of practice as well as management
and maintenance issues etc.
THE STUDY PROCESS
Stage 1 – Background Study
There were two parts in the background study. Part one of the study
covered an extensive literature review on the policies, technologies,
benefits, and good practice case study of vertical greening while part
two of the study recommended different greening treatments that
could be applied to the local context of Hong Kong.
Stage 2 – Schematic Detailed Design
This part of the study provides viable and innovative vertical greening
design and practices with respect to the local context, using a generic
project as illustrative example to ensure practicality in application and
with reference to Government regulations. Under this study, schematic
sketches and illustrations, written control clauses, specifications and
schematic installation details with rough cost estimates were provided.
THE MAIN FEATURES OF THE STUDY
Originality
It was the first attempt by a professional multidisciplinary
team including architect, university
researchers, landscape architect, structural
engineer and quantity surveyor to study vertical
greening in local high-rise context. The study has
identified six vertical Greening treatments that
can be applied including Planting on Wall, Podium
Garden, Sky Garden, Roof Garden, Edge Planting
and Planting in Balcony.
Learning experiences from overseas policies, regulations and guidelines.
Local constraints on Vertical Greening application were studied in terms
of physical (solar radiation availability, maintenance, air pollution and the
side effects created by harmful insects and animals) and non-physical
(user perception) aspects, for instance, many urban inhabitants would
be against the idea of greening their property walls and roofs for fear of
attracting harmful insects mentioned above.
Practicality
The output consists of six greening treatments covering practical
issues such as growing medium, plant species, supporting devices,
maintenance and etc. The treatments are based on international studies,
local climatic, botany and landscape context.
Innovation
Previous studies were conducted in low-rise cities in temperate climates.
This research systematically defined six vertical greening treatments and
explored the application of Vertical Greening in a high rise, high density
urban environment in Hong Kong in order to improve environmental
quality.
