This book introduces a number of vertical greenery systems that are commonly used. It also explains the key environmental benefits of greening walls, and why vertical greenery can be more pervasive feature of urban landscapes. Listed in its Appendix are over 20 suggested plants.
Green Prospects Asia
In recent years, skyrise greenery has come into vogue as green building certification moves into mainstream consciousness in major cities across the world. Much has been published about incorporating vegetation into urban planning to beautify cities, reduce sound pollution and the urban heat island effect, mitigate rainwater runoff and provide general health benefits to city dwellers.
A lot of the literature on green walls (the vertical counterpart to green roofs, or rooftop greenery) is still geared, however, towards addressing conditions in temperate climates, where skyrise greenery is more established, making otherwise excellent books on the topic unsuitable for landscapers and building designers in tropical regions.
One valuable exception to this is Vertical Greenery for the Tropics – a full-colour illustrated introduction to planting green walls where sunshine, heat and humidity are abundant nearly all year round.
Written with Singapore’s “City in a Garden” vision in mind, the book features illustrated examples of green walls from around the island republic. Also included are studies, supported with relevant data, charts and diagrams, that can be used to make a business case for investing in vertical greenery as a means to enhance property value with screening/privacy benefits, acoustic insulation, facade protection, or lower energy bills from the thermal impact of plant shading.
Those new to the topic will find this book accessible introductory reading. This slim 100-pager walks the reader through basics like green wall typologies (support vs carrier systems); key planning considerations such as indoor/outdoor application, desired shading ability, lighting and wind intensity, and suitable profile thickness; installation and maintenance considerations; and irrigation types, including options to incorporate rainwater harvesting into the system. There is also an appendix on suggested plants with the appropriate tolerance or needs for variables like temperature, climbing support, sunlight intensity, soil moisture and growth media. The second appendix is a list of suppliers and irrigation specialists in Singapore that may be useful to local readers.
