Ngee Ann Polytechnicâ€™s Vertical Extensive Green Wall Testing Facility
323 sf.Â Greenwall
Owner: Ngee Ann Polytechnic
Building Type: Educational
Type: Living Wall, Test/Research
Size: 323 sq. ft.
Access: Accessible, Open to Public
Project Description & Details
Early efforts to green up walls and flyovers vertically in Singapore began about 40 years ago with the use of creepers and ornamental plants to increase the aesthetic values. Current vertical greening planter systems implemented in Singapore were mainly from overseas which tend to be heavy, difficult to install and suited for deep rooted plants.

Since over 90% of people in Singapore reside in high rise public housing, infrastructure needs are built on this model. Â For example, public transportation is readily within sight, let alone walking distance, to the vast majority of these high density multi-family dwellings. Â And greening the built environment is taken very seriously here as well – more so on horizontal spaces such as rooftops, or sky gardens as they are commonly referred to here, sky bridges and other connecting devices.
Above is a shot I took from when we visited Singapore last November (when I spoke at the International Skyrise Greenery Conference) where you can see multitudes of housing blocks, and below notice all the greenroofs already in place:
Greenwalls are becoming another very popular “skyrise greenery” element, as well, and there is a growing industry and government help to support it. Â And now indoor greening is also getting attention after the success of theÂ Ngee Ann Polytechnicâ€™s Vertical Extensive Green Wall Testing Facility.
After an October 2009 student design competition where students wereÂ “tasked to create a portable do-it-yourself vertical greenery system,”Â National Parks BoardÂ Singapore’s Centre For Urban Greenery and Ecology (CUGE) Research collaborated with the Ngee Ann Polytechnicâ€™s School of Life Sciences and Chemical Technology and School to develop a simple, inexpensive and attractive vertical greening system for residential homes.
Borrowing some of the ideas from studentÂ submissions,Â researchers from CUGE and Ngee Ann Polytechnic lecturers then “put their heads together to draw out some of the good ideas behind the studentsâ€™ submission and created a product that is user-friendly and practical for home owner.”Â Long Seen Hui and Gregory Chow continue:
“The final invention consists of a stackableÂ system of modules for the support. Each unitÂ can work singly, or in stacks of threes or sixes. The single units and those in stacks of threes may be free- standing on the floor, while the three- or six-unit system can be mounted onto the wall. The single units can also be displayed as miniature gardens on the table.
The system is simple to assemble, easy toÂ maintain and aesthetically pleasing. AlreadyÂ patent-registered, it is designed to fit inÂ most living rooms, balconies or other suitable locations in the homes. Users are able toÂ arrange series of flexible and modular verticalÂ systems to suit their imaginations when greening their walls to provide a maximum impact.
The self-regulating water requirement in eachÂ planting module allows a steady water supplyÂ over extended periods. With an efficient drainage system, plant stress due to lack of water or over watering is prevented, thus removing the guess work on manual watering and providing a healthy growing environment indoors.” ~Â Vertical Greenery for Interior Spaces Made Easy: DIY Vertical Greenery at Home
The second task at theÂ Ngee Ann Polytechnicâ€™s Vertical Extensive Green Wall Testing FacilityÂ was to evaluate shallow rooted plant species for its growth habit, disease susceptibility, nutrient deficiencies and its maintenance requirement.
An instructional DVD along with an instruction booklet is available for purchase at the Garden Shop of the Singapore Botanic Gardens. Â ContactÂ Gregory Chow ofÂ Ngee Ann Polytechnic for more information here:Â email@example.com.
