Singapore: the unveiling of a clean place for clean tech

Singapore’s CleanTech Park, located near Jurong West, is being developed to house clean technology companies in a central location and encourage greater research and development in renewables.

CleanTech Park is situated within a 50 hectare site adjacent to the Nanyang Technological University. It is managed by JTC Corporation, a Singaporean industrial infrastructure specialist in planning, promotion and development.

The first building at CleanTech Park, CleanTech One, is a 37,500 m² multi-tenanted building on a 1.5 hectare plot that brings together clean technology corporations, public research institutes and laboratories to encourage collaboration and innovation in one cluster. Construction of the building was completed in early 2012.

Private sector companies located at CleanTech One include:

DHI Water & Environment, a Danish firm specialising in water and environmental research and consulting
Sinomem Technology, a China-based water purification firm
Solid Asia, a specialist in large-scale solar thermal systems
Advantec, a semiconductor company
The Sustainable Energy Association of Singapore, an industry multiplier.

Japan-based Toray Industries, the world’s largest producer of carbon fibre, has also established its Toray Water Technology Laboratory at CleanTech Park to conduct research and development of water-treatment technologies.

Public sector organisations at CleanTech One include:

The Nanyang Environment and Water Research Institute
The Energy Research Institute from Nanyang Technological University
The Solar Energy Research Institute of Singapore (SERIS).

Laboratories for photovoltaic (PV) module performance analysis and solar-powered air-conditioning are also located in CleanTech One, including the SERIS Testing and Certification Lab, a joint undertaking between SERIS and VDE-ISE Pte Ltd on PV module certification.

JTC has broken ground on the second building in the park, CleanTech Two, kicking off the construction of the second building to meet demand from industry stakeholders requiring space that can accommodate both dry and wet laboratories for clean tech activities. Located next to CleanTech One, CleanTech Two will offer 22,300 m² of office space, laboratories and workshop spaces on a 0.9 hectare site. The building is slated for completion by the third quarter of 2014.

The anchor tenant for CleanTech Two, the Advanced Remanufacturing Research Centre, is a collaboration between public sector research laboratories, academia and private companies aimed at advancing remanufacturing technologies in Singapore. JTC says that while CleanTech One provides laboratories and office spaces, CleanTech Two will be specially configured to support research and prototyping activities that require heavier loadings, higher height clearances and greater electrical power requirements.

The overall development of CleanTech Park is being carried out in three phases over 20 years. Phase one commenced in July 2010, starting with the development of the infrastructure within the park, and has provided approximately 14 hectares of business park land ready for allocation. The park is projected to house a working population of 20,000 when it is fully built in 2030.

The close proximity to the Nanyang Technological University is designed to enhance the integration between academia, research institutes and the Asian clean energy industry, providing synergies for a full value chain from research and development to downstream manufacturing.

CleanTech Park is being developed around a central ‘green core’, a 5 hectare greenfield site containing natural streams that is expected to serve as a social node for the community of researchers and professionals at the park.

Features of CleanTech One

A combination of smart building design and implementation of clean energy infrastructure has helped to create a sustainable surrounding environment for the companies at the first building in CleanTech Park.

Building orientation

Heat gain is minimised by reducing the exposure of air-conditioned area in the east-west façade. Its building staircase and core areas are located in the east-west direction, minimising heat gain and energy consumption.

Naturally-ventilated spaces

This reduces the need for more air-conditioning. Perimeter corridors are utilised to create a buffer between the façade and the laboratories or offices, cutting the envelope thermal transfer value of the building. The atrium is naturally ventilated, with the façade carefully designed with a wind wall that channels wind through the two tower blocks, improving air circulation.

LED lighting

CleanTech One employs LED lighting for all common areas. Occupancy and sensor-controlled dimming and switching capabilities are also installed; lights will dim depending on the intensity of sunlight in the room.

Sky trellis

This project is designed to lower heat build-up on the building façade. A green canopy will be constructed between adjacent buildings to lower heat built up on the building façade as well as the immediate area between the buildings. With the lowering of ambient heat, there is reduced demand for air-conditioning.

Clean energy generation

A 231 kilowatt solar PV system occupies the roof space on CleanTech One.

A 1 megawatt integrated hydrogen fuel cell plant is on site to drive fuel cells. Hydrogen is produced through the thermolysis of water in the presence of a proprietary technology. Hydrogen generated is used in an array of Proton Exchange Membrane fuel cells to produce electricity that powers up to 20 per cent of CleanTech One’s electrical loads.

Use of recycled building and civil work materials

Eco-concrete and green concrete were used for non-structural and structural works respectively through the partial substitution of concrete constituents and recycled aggregates. CleanTech One contains green concrete extensively throughout the structural elements, which include bored piles, pilecaps, columns, walls, beams and slabs.

CleanTech One also re-used construction waste; soil excavated during construction was retained for reuse in planting operations. The use of a formwork system helped to promote faster casting, and – coupled with a better quality of form finish – helped to reduce material waste.

Waste segregation

A comprehensive building level program for recycling takes into account how the output of a waste stream can be used as an input for another process. A recycling program is in place to recycle key waste streams such as paper, plastic, aluminium, glass waste and e-waste from CleanTech One.

The clean tech industry is a strategic growth area that is expected to contribute $S3.4 billion to Singapore’s gross domestic product and create jobs for 18,000 by the year 2015.
