Ngee Ann Polytechnic’s Vertical Extensive Green Wall Testing Facility
323 sf.  Greenwall

Year: 2009
Owner: Ngee Ann Polytechnic
Location: Singapore
Building Type: Educational
Type: Living Wall, Test/Research
System: Custom
Size: 323 sq. ft.
Slope: 100%
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.

The Landscape Design and Horticulture programme from the School of Life Sciences and Chemical Technology at Ngee Ann Polytechnic embarked to develop “simpler” green walls for high rise buildings where 90% of residences are dwellers. The 2-year research on sustainable plant species for the green wall involved 40 students and the outcome was a 12m x 2.5m vertical extensive green (VEG) system implemented in 2009. The VEG comprised of 120 polypropylene panels (50 x 50 x 3cm) that were pre-grown with shallow rooted vegetative cuttings and plantlets. Eleven species of grass, bromeliad, creeper and fern on shallow panels filled with cocopeat (2% osmocote) were tested for their long term growth performance.

Additional Info

Since over 90% of people in Singapore reside in high rise public housing, infrastructure needs are built on this model.  For example, public transportation is readily within sight, let alone walking distance, to the vast majority of these high density multi-family dwellings.  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.  And now indoor greening is also getting attention after the success of the  Ngee Ann Polytechnic’s Vertical Extensive Green Wall Testing Facility.

After an October 2009 student design competition where students were  “tasked to create a portable do-it-yourself vertical greenery system,”  National Parks Board  Singapore’s Centre For Urban Greenery and Ecology (CUGE) Research collaborated with the Ngee Ann Polytechnic’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 student  submissions,  researchers from CUGE and Ngee Ann Polytechnic lecturers then “put their heads together to draw out some of the good ideas behind the students’ submission and created a product that is user-friendly and practical for home owner.”  Long Seen Hui and Gregory Chow continue:

“The final invention consists of a stackable  system of modules for the support. Each unit  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 to  maintain and aesthetically pleasing. Already  patent-registered, it is designed to fit in  most living rooms, balconies or other suitable locations in the homes. Users are able to  arrange series of flexible and modular vertical  systems to suit their imaginations when greening their walls to provide a maximum impact.

The self-regulating water requirement in each  planting module allows a steady water supply  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.” ~  Vertical Greenery for Interior Spaces Made Easy: DIY Vertical Greenery at Home


The second task at the  Ngee Ann Polytechnic’s Vertical Extensive Green Wall Testing Facility  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.  Contact  Gregory Chow of  Ngee Ann Polytechnic for more information here:

GPW: Universal Studios Singapore

July 9, 2011 at 7:53 pm Project of the Week: 7/4/11
Universal Studios Singapore
376,737 sf. Greenroof

Year: 2010
Owner: Resorts World at Sentosa Pte Ltd
Location: Singapore
Building Type: Commercial
Type: Extensive
System: Single Source Provider
Size: 376,737  sq.ft.  
Slope: 1%
Access: Inaccessible, Private

Project Description & Details

Universal Studios Singapore, an integral part of Resorts World Sentosa, is a casino-resort off the south coast of Singapore occupying almost 124 acres.  Amid the make-believe world of movies, roller-coaster rides, theme dining and shopping, down-to-earth issues in the Park were not ignored.  Sustainable “green” features including solar panels and nearly 35,000 M2 of green roofs were extensively integrated into the theme park’s concept and design, showing its firm commitment to energy conservation and responsible environmental stewardship.  Resorts World Sentosa received the Singapore Building and Construction Authority’s Green Mark District GoldPlus Award.

Elmich Green Roof  was used as the wide structural spans of the immense roofs and fast track construction of the Park demanded that the system selected must be light and easy to install.  Elmich Green Roof comprises a VersiDrain ® 25P water retention and drainage layer, a geotextile filter layer and EnviroMix ® GR, a primarily inorganic soil-less lightweight planting media and drought-tolerant plant species that require little maintenance. For the metal roofs, VersiCell ® structural drainage/insulation cells were used to fill the space between the metal ridges to create a level flat surface first, on which a separation sheet was installed. For the concrete roofs, waterproofing is provided by a fully adhered layer of root-resistant Evalon PVC/EVA terpolymer membrane. An irrigation system is incorporated for use during the initial plant establishment and to provide regular irrigation and fertilization on the roofs, especially essential in prolonged periods of drought.

Additional Info

The reported $4.32 billion Resorts World Sentosa offers something for everyone, from business travelers to families in search of the ultimate holiday, and certainly to sustainable design fans looking for a greener vacation!

This unique travel destination is home to six hotels, spa villas, the world’s largest oceanarium – Marine Life Park – Asia’s largest column-free ballroom (which seats 7,300 guests), and the first and only Southeast Asian Universal Studios theme park with its multiple lush yet equatorial hardy  greenroofs.

In early 2010 Resorts World Sentosa had a soft-opening, with four hotels and the Universal Studios Singapore, among other features.

The region’s only world-class movie theme park just celebrated its official grand opening on May 28, 2011, and its red carpet event was attended by famous Hollywood and Asian celebrities including Jet Li, Maggie Cheung, Vicki Zhao and Paula Abdul.

Unseen by the celebrities and most visitors to the park, except for roller-coaster riders, a real green carpet is rolled out everyday on the rooftops of the park.   Amid the glitz and glamour, approximately 377,000 sf of lush vegetated roofs provide beyond just a touch of green to the resort – they offer a cooler environment both inside and outside the buildings.

“The resort integrates three key elements – water, greenery and built form with careful detailing in the articulation of the facades, the use of a palette of natural materials and colours, extensive planting and the consistent treatment of sun shading devices such as overhanging pitched roofs, covered walkways, awnings, trellises and latticework to fuse the resort with the tropical climate context. ” ~  Roof & Façade Asia

The Elmich Green Roof system provides a barrier against tropical temperatures.  The top photo below shows the installation of the  VersiCell ® structural drainage/insulation cells which will  fill the spaces between the roof’s metal ridges to create the flat planting level, and the bottom shows theVersiDrain ® 25P water retention and drainage layer:

Aside from eco-friendly design, other corporate sustainability efforts have included participating in Earth Hour 2011 – according to the  Resorts World Sentosa  blog,  at the stroke of 8.30 pm on March 26, “the resort dipped into limited electricity mode – with landscape, canopy and non-essential lightings as well as water fountains in areas all across the resort turned off.”

Just a couple of other sustainable initiatives include:

* Lowering energy consumption from air-conditioning across the resort through the use of extensive canopies to reduce ambient temperature and energy-friendly eco-coolers:
* Trees that were preserved during construction of the resort (122 of them!) have either been replanted or recycled into benches at the Festive Walk.

Find out more on Resorts World’s corporate social responsibility efforts here.  I wish we could have seen some of these spectacular Universal Studios Singapore greenroofs  when we visited the lovely island nation of Singapore last November!  Singapore has some incredible greenroofs, for sure, and it’s hard to beat the sheer quantity found here within the  Universal Studios Singapore:
