News Holcim launches Singapore Centre of Excellence
The opening of the CoE also marks Holcim’s 100 years in operation worldwide Singapore: In an effort to increase the level of sustainable construction in Singapore, Holcim has unveiled its Centre of Excellence (CoE), the first in Asia, in Singapore recently. Officially launched by Lam Siew Wah, Deputy CEO of Singapore Building and Construction Authority, the event was attended by among others, Jörg Al. Reding, Switzerland’s Ambassador to Singapore and Goh Chee Kiong, director of Building and Infrastructure Solutions and Cleantech at the Singapore Economic Development Board. Built at the cost of around half a million dollars, the CoE marks the Company’s commitment to developing sustainable and value-adding solutions, partnering esteemed clients - developments that encompass green solutions, productivity enhancing solutions, customised solutions and innovative materials technology solutions in contributing to Singapore’s built environment and beyond. The opening of the CoE also marks Holcim’s 100 years in operation worldwide. As an expression of its commitment to its stakeholders, Holcim Singapore will also be increasing efforts and programmes for human resource development and capabilities enhancement. In its latest move, it has added about 6000 sq feet to its new facility, to emphasise its presence in Singapore and its extended operations in Asia. “The importance of sustainable construction in Singapore due to the lack of natural resources affirms our strategy. With the new state-of-the-art development capabilities and the highly innovative workforce therein, we now have the infrastructure to accommodate our existing operations as well as meet the demands for on-going growth. We are firmly committed to Singapore as the ideal platform to efficiently reach our customers and supply chain. With the new office, we are also committed to providing a conducive working environment for our employees,” said Dr. Sujit Ghosh, Chief Executive Officer of Holcim (Singapore). Established in 1912, in the village of Holderbank in the Swiss Cantou of Aargau, Holderbank and then later as Holcim, the company has grown steadily to become one of the world’s leading construction materials companies. It now holds majority and minority interests in around 70 countries on all continents. Today, with 80,000 staff strength, Holcim is one of the world’s leading suppliers of cements, aggregates, ready-mix concrete, asphalt and services. “Singapore’s strong commitment to sustainable development provides a sophisticated lead market for companies to innovate and showcase new solutions. We warmly welcome Holcim’s
decision to locate its first Asia-Pacific Centre of Excellence in Singapore to develop sustainable building solutions for the regional markets,” said Goh Chee Kiong, Director of Building and Infrastructure Solutions, and Cleantech at the Singapore Economic Development Board. Establishing its Asian presence in Singapore since 1994, Holcim Singapore’s business today stretches from supplying cement and advancing ready-mix concrete technology with innovative solutions to providing application-based dry mix and wood replacement products. “Overall, Singapore’s construction industry and its sustainability journey will benefit from Holcim’s R&D efforts and innovations. With increasing pressure on global resource scarcity resulting in the volatility of commodity prices, the development of alternative resources will benefit Singapore in the long run. The opening of the Centre of Excellence is a significant milestone of Holcim’s partnership with Singapore and their firm commitment to Singapore’s sustainability drive,” said Lam Siew Wah, Deputy CEO, Building and Construction Authority. Numerous projects in Singapore have already benefited from Holcim’s innovations, including the Supertrees at Gardens by the Bay where self-compacting high-early-strength Holcim Green structural concrete was used. Since January 2009, Holcim has delivered more than 3,000 cubic meters of concrete to the Bay South jobsite alone. Another noteworthy recent development in 2010 has been “Easecrete” which is a productivity enhancing solution that was welcome by the BCA and the construction industry and several prestigious projects across Singapore are using it and witnessing its unique benefits. Many new and exciting developments are underway at Holcim Singapore like the “Floatcrete” (concrete that floats in water); structural “LightCrete”; architectural “imprintcrete” and so on, and the company is confident that several of these developments shall be heavily embraced by the building and construction industry, locally and regionally, as truly value-adding! A frequent winner of many accolades -- the Singapore Environmental Achievement Award Top Achiever 2008/2009 and Green Leadership Award at Asia Responsible Entrepreneurship Awards 2009, Holcim Singapore will continue to enrich its value propositions as it embarks on extensive development efforts to deliver innovative solutions. It is fully committed to maintaining its leadership position by building customer and stakeholder value through enhancing productivity and delivering excellent customer service. RFA
NHLA pushes for Klin Drying certification at AHEC’s meet The American Hardwood Export Council (AHEC) held its 17th Southeast Asian and Greater China Convention in Singapore’s St. Regis Hotel in June. Attended by over 400 delegates from all over Asia and the USA, the Convention was aimed at delivering the positive environmental message of American Hardwoods to Asian markets. Six keynote speakers presented papers on American hardwood under the theme ‘American Hardwood and Green Design – Life Cycle Assessment and the True Environmental Impact of Material Choice.’ Positioned as a landmark event for AHEC in South East Asia, the convention hosted trade representatives from various chambers. National Hardwood Lumber Association (NHLA) was represented by Director of Communications Renee Hornsby and Chief Inspector Dana Spessert. Michael Snow, Executive Director of AHEC and Rupert Oliver, Director of Forest Industries Intelligence, provided a detailed progress report of AHEC’s Life Cycle Assessment (LCA) study. They presented the latest data showing the lighter carbon footprint of American hardwood exports, based on scientific data as the precursor to developing Environmental Product Declarations (EPDs) for all American species shipped to Asian destinations. Speaking on the occasion, Dana Spessert reported on NHLA’s KD Certification Scheme. Ted Rossi, former NHLA president, introduced and explained the US government’s Animal & Plant Health Inspection Programme (APHIS), which is primarily to protect US agriculture. APHIS certificates have become increasingly difficult to obtain for many reasons including government cutbacks and can often lead to missed shipments. APHIS has issued a Memorandum of Understanding for NHLA to work as an administrator in the processing of an alternative to the APHIS certificate, the NHLA Certification of Kiln Drying Sawn Hardwood Lumber Program. Under the APHIS – approved program, NHLA is using a third party organisation Timber Products Inspection (TPI), which already monitors softwood, to verify the process. TPI will be inspecting kiln drying and heat treatment facilities. The new NHLA KD Certificates have already been approved by some countries including Vietnam and there has been preliminary acceptance from the EU. Dana Spessert, explained the process and requirements for the new certificate in which Plant Processing Manuals will be a requirement including a description of the species. Kiln Drying Certification includes proof of segregation of kiln dried and green lumber. Clip IDs will be provided by NHLA and that number must go on the certificate and tally with the lumber. Audit procedures were explained to delegates, that program participants must be inspected monthly for their kiln treatment records; moisture testing records; segregation etc. Countries accepting the NHLA certificate are Australia (but at a higher temperature), Brazil, Mexico, Vietnam and the EU. The latter has passed a sub-committee review and full approval is expected in autumn 2012. All delegates received a copy of the newly published American Hardwood Supplements in English and Chinese featuring a two page spread on NHLA’s expanding international influence and details of the NHLA Chicago Convention. One of the lasting images for members visiting Singapore for the first time was the welcome party at Ku De Ta high above the Singapore waterfront showing off the spectacular development of this small Southeast Asian Nation.

Designer Gardens Grant Associates has created a new landmark in Singapore by completing first of the three planned gardens under ‘Gardens by the Bay’ project.
he first phase of Singapore’s dramatic ‘Gardens by the Bay’ project was opened to public on 29th June following completion of the 54-hectare US $785 million Bay South Garden by a British design team led by Bath-based landscape architects, Grant Associates. Considered as one of the largest garden projects of its kind in the world, the site will ultimately have 101 hectares of land comprising three distinct gardens – Bay South, Bay East and Bay Central. Located on reclaimed land in Singapore’s new downtown at Marina Bay, the site will provide a unique leisure destination for local and international visitors. The project is an integral part of Singapore’s “City in a Garden” vision, designed to raise the profile of the city globally whilst showcasing the best of horticulture and garden artistry. "Our brief for Gardens by the Bay was to create the most amazing tropical gardens in the world, incorporating cutting-edge environmental design and sustainable development principles. We had to factor in the challenges of both the Singaporean climate and working on a reclaimed waterfront. We wanted to capture people’s relationship with nature and use innovative technology to create rich lifestyle, educational and recreational experiences for both local residents of Singapore and visitors from around the world. All these elements informed the vision and creation of the gardens,” says Andrew Grant, Director of Grant Associates. Following an international design competition, a team led by Grant Associates was appointed in 2006 by the National Parks Board of Singapore to master plan Bay South Garden, the first and largest of the three planned gardens at Gardens by the Bay. Alongside the lead designers Grant Associates, the British design team for Bay South includes Wilkinson Eyre (architects); Atelier Ten (environmental design consultants); Atelier One (structural engineers); Land Design Studio (museum and visitor center designers) and Thomas Matthews (communication designers). 6 | Roof & Facade Asia Asean Edition | July May 2012 June 2012
A fusion of nature and technology
Taking inspiration from the form of the orchid, Grant Associates’ master plan is a rich fusion of nature, technology and environmental management. Stunning architectural structures are combined with a wide variety of horticultural displays, daily light and sound shows, lakes, forests, event spaces and a host of dining and retail offerings. The whole plan has an intelligent environmental infrastructure, allowing endangered plants, which could not normally grow in Singapore to flourish, providing both leisure and education to the nation. "We were very fortunate to work with the right team to make the vision for Gardens by the Bay work. Our ethos as landscape architects is collaborative. Working with great architects, engineers and environmental specialists we created some very imaginative and innovative ideas that the National Parks Board championed. With these elements, the end result at Gardens by the Bay is wonderful, impactful and powerful. It’s been a dream project to work on," says Keith French, Project Director for Gardens by the Bay at Grant Associates.
Cooled Conservatories The Conservatory Complex is an architectural icon, a horticultural attraction and a showcase of sustainable energy technology. Two giant biomes designed by Wilkinson Eyre Architects – the Flower Dome (1.2 hectare) and the Cloud Forest Dome (0.8 hectare) – display plants and flowers from the Mediterranean-type climatic regions and Tropical Montane (Cloud Forest) environments and provide an all-weather “edutainment” space within the Gardens. The Flower Dome replicates the cool-dry climate of Mediterranean and semi-arid sub tropical regions like South Africa and parts of Europe like Spain and Italy. The Cloud Forest Dome replicates a cool-moist climate found in Tropical Montane regions between 1,000 to 3,500 metres above sea level, such as Mt Kinabalu in Sabah, Malaysia, and high elevation areas in South America. To ascertain the environmentally sensitive energy requirements of the Conservatory, NParks commissioned an energy modeling study. The study shows that, by applying the latest cooling technologies, the energy consumption for the Conservatory is comparable to that of an average commercial building in Singapore of the same footprint and height, normalised to a 24-hour cooling period.
Supertrees Between 25 and 50 metres in height, the 18 Supertrees
designed by Grant Associates are iconic vertical gardens, with emphasis placed on creating a “wow” factor through the vertical display of tropical flowering climbers, epiphytes and ferns. At night, these canopies come alive with lighting and projected media. An aerial walkway suspended from the Supertrees offers visitors a unique perspective on the gardens. The Supertrees are embedded with sustainable energy and water technologies integral to the cooling of the Cooled Conservatories. Supertree comprises four major parts created by structural engineers Atelier One. • Reinforcement concrete core – Inner vertical structure that upholds the Supertree. • Trunk – A steel frame attached around the reinforcement concrete core. • Planting panels – Installed on the trunk in preparation for the planting of the living skin. • Canopy – Shaped like an inverted umbrella, the canopy was assembled and hoisted via a hydraulic jack system (with the exception of the 50m Supertree canopy assembled at its final height). Other Bay South Garden attractions include: Dragonfly Lake, which is one-km-long lake creating a dramatic setting to the Supertrees and Conservatories; Marina promenade, a one-km tree lined walkway along the Marina edge linking the city centre with the Barrage; Tadpole Play Area, a nature themed playground set within a planted rainforest; Fragile Forest – this has been created using native species to simulate a typical Southeast Asian Rainforest and Events Lawn, a large open space capable of holding outdoor concerts and events for more than 10,000 people.
Horticultural Gardens Two collections - Heritage Gardens and World of Plants - centre on the subjects ‘Plants and People’ and ‘Plants and Planet’. Together with mass flowering and coloured foliage landscape, they form a spectacle of colour and texture and fragrance within the Gardens, providing a mesmerising experience for visitors.
Heritage Gardens This is a collection of four gardens -- Malay garden, Indian garden, Chinese garden and Colonial garden -- that reflect the history and culture of Singapore’s main ethnic groups as well as the city-state’s colonial heritage. Each Garden explores the rich cultural significance of different plant species including their symbolism, religious significance, trade, food and medicinal uses etc
World of Plants The second collection of gardens is based on the theme “Plants and Planet” and showcases the biodiversity of plant life on our planet. There are 6 gardens in total -- Secret Life of Trees, World of Palms, Understorey, Fruits and Flowers, Discovery Garden and Web of Life. "Gardens by the Bay provides a unique green space and horticulture-themed leisure destination in the heart of the new downtown at Marina Bay, for everyone to enjoy and cherish. It has been an incredible journey for our horticultural and development staff to bring the gardens to life. We are excited to finally share the treasures of this new garden with Singapore and the rest of the world,” sums up Dr. Kiat W. Tan, CEO, Gardens by the Bay.

New look V on Shenton A new UIC building will help rejuvenate the area of Shenton Way in the heart of Singapore’s Central Business District.
he UIC building has been part of the Singapore skyline since 1973 and, for some time, remained the tallest building in Singapore. Located along Shenton Way in the heart of Singapore's Central Business District, the new UIC redevelopment, ‘V on Shenton,’ will remain as a signifier of the business and architectural strength of Singapore. Today, the area is undergoing rejuvenation and transformation and V on Shenton forms part of this redevelopment. The dual programming of office and residential is a unique situation in this area and the massing of the towers is designed to reflect this. The office tower corresponds to the scale of the area opposite the residential tower, which rises up to distinguish itself from the surrounding buildings. The twin tower of V on Shenton is comprised of a 23-storey office building and a 53-storey residential tower. The angle in the office tower roof corresponds to the upper of two midlevel sky gardens of the residential tower, which rises up to distinguish itself from the neighbouring buildings. Above this sky lobby, the unit mix of the residential tower changes with a subtle display of its split core. This separation also exhibits the natural ventilation concept of the tower,
8 | Roof & Facade Asia Asean Edition | July 2012
which is further effected through ventilation slots next to the cores. Distinctive to V on Shenton, designed by UNStudio, these slots are covered by façade cladding with openings for air circulation, resulting in a continuous, uninterrupted hexagonal façade pattern on the residential tower.
Facade Just as the office and residential towers are of the same family of forms, so do their facades. The basic shape of the hexagon is used to create patterns that increase the performance of the facades with angles and shading devices that are responsive to the climatic conditions of Singapore. The office tower is based on a curtain wall module and an optimised number of panel types, recombined to create a signature pattern. In contrast, the residential facade is based on the stacks of unit types. The pattern of the residential facade is created by the incorporation of the residential programme (balcony, bay window, planter and a/c ledge) and the combination of one and two storey high modules with systematic material variations. These geometric panels add texture and cohesion to the building, whilst reflecting light and pocketing shade. The texture and volume of the facade are important to maintaining the comfort of those living and working in
the residential and office buildings. Shading devices and high-performance glass are important for developing a sustainable and liveable facade. Each tower is framed by "chamfers"; a line that unifies the composition of the residential tower, the office tower and the plinth. During daytime the chamfer appears smooth in contrast to the textured surfaces of the towers. At night the chamfer lights up as a continuous line framing the towers, car park and sky gardens. The chamfers at the North end of the office tower also open up the corners to views of Marina Bay, Buket Timah Hill and the Central Business District.
Lobbies On the ground floor of the development stainless steel lines are inlaid into the floors and lines of light are traced across the ceiling, guiding pedestrians to their destination. The design of the residential lobby uses the car park ramps to bring continuity from interior to exterior. The lines of light move from the exterior covered walkway into the lobby, accentuating the ramps above, while the ceiling rises into a double height space at the elevators. The office lobby is divided into a reception area and a
large cafĂŠ which extends along the view corridor to create a lively atmosphere in the public areas.
Sky Gardens The sky lobbies and the sky garden are an integral part of V on Shenton and provide 360 degree views of Singapore. The most ample and diverse of the three sky gardens covers the entire 8th storey of the development. Here residents are able to take full advantage of the amenities while still having privacy to train or entertain guests. Along with the facades, the sky gardens are an integral part of developing the sustainable lifestyle. These lush green spaces provide a refuge from the city with the climate and vegetation naturally providing fresher and cleaner air. At the two sky lobbies in the heart of the residential tower, residents are given even greater privacy combined with views of the city or the ocean from both the 24th and the 34th storeys. The residents of the penthouse levels will also have exclusive access to the outdoor roof terraces on the 53rd and 54th storeys.

Trumps Up! Broadway Malyan-designed Trump Tower Manila breaks ground in The Philippines
round works have begun on the Trump Tower Manila, designed by global architecture, urbanism and design practice Broadway Malyan, with the tower set to be the tallest residential skyscraper in The Philippines, when completed in 2016. Being developed by Century Properties, the four hectare mixed-use development will become a landmark in Manila’s most prestigious financial and commercial district, Makati City. When completed, the 58-storey building will stand approximately 250 metres tall and have 220 residential units. Director Ian Simpson, who has led the practice’s team, said, “Ground breaking is a major milestone in the delivery of this landmark project, which has drawn on the skills, expertise and experience of our world-class design team working in partnership with the client, with the tower set to redefine lifestyle living in Asia as well as the Makati skyline."
Peeled façade Broadway Malyan’s design, which won the ‘Best Residential High-Rise Architecture’ (The Philippines) category at the Asia Pacific Property Awards 201213, is based on the concept of a 'peeled façade’ of an extruded square, articulated with internal box ledges and external terraces at the top and bottom corners that peel away and accentuate the dynamic form of the tower. 10 | Roof & Facade Asia Asean Edition | July 2012
An environmentally-responsive skin, featuring light shelves and shading systems to react to the building's orientation in relation to sun's path, will help to improve building performance whilst maximising the spectacular panoramic views of the city.
Design features The building’s compact footprint and extruded form are designed to balance the architectural delight, of what is set to be the most noticeable icon in the Philippines, with sustainable restraint, with energy consumption reduced through a low surface to volume ratio to set a new benchmark in lifestyle green living. Suites of approximately 613 square feet comprising of one to four bedroom apartments, and penthouses of approximately 425 square metres (4,574 square feet), will provide a diversity of unit types to cater for different spatial and economic needs. The luxury residences will offer world-class city living with exclusive facilities, with the tower set to be the first condominium in the world to offer a selection of Hermès home collections for its amenities and common areas. Lifestyle is central to the concept and a range of different recreational, health and well-being facilities will be positioned throughout the tower. The intermediary skygarden located on the 30th floor will host amenities including an infinity lap pool, juice bar, gym, stylish spa lounge, treatment rooms, sauna and steam rooms, as well as a beauty salon.
Mixed Use Buildings
Meanwhile, the business centre will provide an exclusive space with meeting, function and video rooms, a library, lounge and garden terrace, and a fine-dining restaurant will be located on the ground floor. The towerâ€™s green credentials are further enhanced by a high-performance curtain wall system that incorporates light shelves that act as shading devices as well as a means of bouncing light deeper into the apartments. Vertical fins to the east and west elevations will also counteract the negative attributes of low angle sun, while preserving the panoramic views across the City. A series of sky terraces and extended box ledges of differing sizes will peel back from the faĂ§ade at the top and bottom corners of the tower to counteract the highest impact of the sun and function as an effective shading device.

et Zero Energy Building (NZEB) is a concept, where by the building is designed to achieve the highest standards of energy efficiency. Due to the complex nature of the term’ zero emissions’, it is measured and reported differently. The four definitions accepted by National Renewable Energy Laboratory (NREL) and U.S. Department of Energy (DOE) to describe different types of ZEBs are as follows: n Net Zero Site Energy: A net zero site energy building is one that produces at least as much renewable energy in a year as it uses in non renewable energy, when accounted for at the site. n Net Zero Source Energy: A building that produces at least as much energy as it consumes in a year, when accounted for at the source, is defined as net zero source energy building. To calculate a building’s total source energy, imported and exported energy are multiplied by appropriate site-to-source conversion multipliers to account for the energy losses through conversion inefficiencies and losses in transmission and distribution. n Net Zero Energy Costs: A net zero energy costs building is one where the amount of money paid by the utility to the building owner for the energy sold by the building to the utility grid is at least equal to the amount the owner pays the utility for the energy services and energy used over the year. In this case the owner’s net energy bill is either zero or negative. n Net Zero Energy Emissions: A building that produces and exports at least as much emissions-free renewable energy as it uses from emission-producing energy

sources annually. Carbon, nitrogen oxides, and sulfur oxides are common emissions that net-zero energy emissions buildings offset. Even with advancements in the concept of zero emissions building world over, it is still in the conceptual stage in the Asia-Pacific region. A few pilot projects have been applied to buildings, such as research institutes, commercial office buildings, but these have been largely for demonstration purposes. The following section, discusses case studies of zero emission buildings from four different nations in South Asia; namely China, India, Malaysia and Korea.
Case Study 1: Ningbo’s Sustainable Energy Technology Center, China
The University of Nottingham Ningbo’s, Sustainable
Special Feature Energy Technology Research Centre building in China, has been built using sustainable technologies to achieve the status of the first Zero Carbon University in China. The 1300m2 building has been built with a budget of 5million Euros. Much of the energy requirements of the building are met by renewable energy sources, like photovoltaic power generation systems, geothermal energy, passive systems like natural light and ventilation, rain water harvesting and water recycling. It has been calculated that in the next 25 years, this building can reduce coal consumption by 448.9 tons and carbon emissions by 1081.8 tons. Design Strategy: The building design is based on environmental design strategy, where by the building envelop is designed to utilize the natural elements to maximum. The building features exposed thermal mass, daylight & solar control, natural ventilation to the tower, and piped ventilation to the laboratory & workshop areas. Exposure to any excessive radiation is reduced by double glazing, with a printed screen in the middle. The rooftop has large openings to allow for ventilation and natural light; however, the excess radiation through the windows is reduced by providing a tilt to the openings. The building is designed so that its electrical energy needs for cooling are only 7-8 kWhr / m2 a year. The shell of the structure is well insulated with high thermal capacitance in internal floors & walls and a ventilated, glazed south façade. Energy Performance: The building does not require a conventional heating system. In extremely cold season, the ventilation air is preheated and the surface temperatures are raised using additional heat. The south façade of the building passively pre-heats ventilation air, supplied by natural convection to the teaching rooms, offices, & meeting rooms. A reversible ground source heat pump is used to provide heating through coils embedded in the soffit of the concrete floor.
Figure 3: Ningbo’s Sustainable Energy Technology Center (Source: http://www.archello.com/en/project/centre-sustainable-energytechnologies)
During other times when cooling is required, the thermal capacitance of the internal concrete surfaces are designed to keep the internal areas cool. The ventilation air is pre-cooled using ground tubes and dehumidified mechanically by an air handling unit. The treated air is then channelled through the light well into the working areas and exhausted naturally through the façade openings. Solar collectors provide energy to absorption package chillers to deliver cooling to the AHUs. The reversible ground source heat pump provides cooling to the ceiling of the concrete floor, and the electric power for dehumidification is provided by the photovoltaic system. During months when the weather is fine, natural ventilation is encouraged. For maximum benefits, the vents are controlled automatically by means of vent opening gear within the perimeter glazing. The photovoltaic system produces enough power during peak periods of sunshine to run other equipment such as lifts, mechanical ventilation, & chilled water systems. Any extra power that is generated is either stored in batteries or is transferred to the nearby sports centre, depending on the requirements.
Case Study 2: Bayer EcoCommercial Building (ECB), India As part of its sustainability program, Bayer is building net zero energy/emission commercial buildings in major regions of the world. Their aim is to showcase the viabil-
ity of its EcoCommercial Building initiative which has net goal to save energy, cut emissions, increase comfort, and reduce lifecycle costs. The EcoCommercial building, in Greater Noida, India, is the first example of a zero-emissions building to be developed as part of the commercial buildings. The design of the building was developed in cooperation with Bayer Technology Services, architects Banz & Riecks, and energy specialists Solares Bauen GmbH and takes into account both the local climatic conditions and the technical infrastructure at the site. Design Strategy Comprehensive computer simulations were used to develop the design for this cubic, two-story building. The building with 900m2 of floor space receives 100 percent of its power requirements from a photovoltaic plant situated on its roof top and needs about 50 percent less power in comparison to other buildings in the region. In its response to the extreme climatic variations, the walls, roof and floors of the building have been insulated with rigid foam called, Polyisocyanurate Thermal Insulation (PIR). The insulation foam protects the building envelope from the extreme heat, and reduces the amount of energy required for keep the internal space cool through air conditioning. The products and systems used were sourced locally to reduce the carbon footprint of the building. Over its service life time, it is estimated that the insulation material will help save about 70 times as much energy as is needed to produce it. Highly efficient air-conditioning and lighting systems are also used in the building for energy saving. Thermal modelling has been used to get the precise ratio of openings to walls to achieve highest level of efficiency in energy management. Transparent surfaces have been used very innovatively to allow natural light while cutting out on extreme heat radiations, unwanted strong breeze etc that may disturb the working environment inside the building. These transparent surfaces make up about one third of the total building area. The openings have also been protected by Polycarbonate glazing, use of which along with other design features, have reduced the total energy consumption of the building far below than the average in India. Energy Performance: The building has a photovoltaic (PV) system on the roof, which is aligned with the path of the sun and meets 100 percent of its energy needs. This has enabled the building to avoid the emission, equivalent to the CO2 emissions of around 20 vehicles. The PV system generates 72,000 kilowatt hours (kWh) of energy, whereas the building used nearly 64,000 kWh over the same period which results in a surplus of more than 8,000 kilowatt hours of energy. The building is CO2 neutral as the energy consumption for heating, cooling, ventilation and lighting is completely produced by PV system, a renewable energy source. The building, apart from being ecologically beneficial, is also economically attractive as it is anticipated that the ecologically sound measures implemented in the project will pay for themselves in no more than ten years.
Case Study 3: Pusat Tenaga Malaysia’s Zero Energy Office (ZEO) Building, Malaysia Pusat Tenaga Malaysia (PTM) headquarters showcases that sustainable and energy efficient technologies can be used to achieve a Zero Emission Office Building (ZEO). The building uses rage of active and passive systems to achieve net zero emissions building, using only 286 kWh per day and thus leading to energy savings of 576,000 kWh per year and mitigating 350 tonnes of CO2 per year. The building meets its overall objective of zero energy consumption with minimum investments required. The building uses passive features like North- South orientation of building to reduce unwanted extreme solar gains, heavy insulation of walls and roofs and double glazing for the openings. The building is primarily lit
using natural daylight systems, where energy efficient bulbs are provided for dark and overcast periods. Measures have been taken to reduce the energy requirement for functioning of the building, like use of high efficiency chillers, use of high efficiency lighting controlled according to demand, high efficiency pumps and fans, and use of energy efficient office equipment. The building has integrated PV system which is connected to the grid. During day time, the power generated from solar energy is exported to the grid; whereas, during the night power is brought back from the grid to run the chillers. This way, power is utilised during the off peak hours. Cooling is stored in the concrete floor slabs and in a chilled water tank. During daytime, the building areas are cooled passively from the chilled floors and the ceilings. A downsized mechanical ventilation system connected to the chilled water tank provides fresh and dehumidified air into the building, improving the working environment. The precise temperature range of 24- 26 degrees Celsius is maintained using active ventilation systems. The building roof, covered by the Photo Voltic panels serves dual purposes. Along with capturing sun power to generate electricity during the day time; at night time, the PV roof becomes the “cooling tower” for the chiller. The roof will be covered by a thin water film, which will emit heat from the chiller to the sky and to the cool night air.
Solar BIVP System All the energy requirements of the building is provided for by its own solar BIPV systems. Four different solar BIPV systems utilising four different technologies have been installed into PTM’s ZEO. The first and biggest component features the 47.28 kWp polycrystalline BIPV system on the main roof; the second component lies with the 6.08 kWp amorphous silicon BIPV system incorporated into the second main roof; the third system stored in the atrium of the building highlights the use of the 11.64 kWp monocrystalline glass-glass BIPV system; and lastly, the car park roof is fitted with 27 kWp monocrystalline BIPV system. These systems are all linked up to grid-connected inverters that convert the direct current (DC) electricity into alternating current (AC) power. The system does not have batteries, as the generated solar power is directly consumed and the net surplus is sold to the grid, Tenaga Nasional Berhad (TNB), on a net meter basis. The building sets an example of the use of energy efficient technologies, with solar BIPV setting a new standard for sustainable buildings in the ASEAN region
Case Study 4: National Institution of Environmental Research in Republic of Korea: To demonstrate zero-energy technologies, the National Institution of Environmental Research, has constructed a carbon-zero building, with funding support from the Korean Government. The project took three years to complete (2008–2010), at a cost of US$3,000 per square metre. US$93,577 of annual budget saving through energy Reductions are expected, along with 100 tonnes per year of CO2 emissions. The total annual energy consumption in the carbon-zero building amounts to 123.8kWh per square metre. The building has used about 30 energy consumption reduction technologies, 18 energy efficiency technologies, and 13 new and renewable energy technologies.

Beyond Beyond Green Green
Engineering: What is Green Engineering?
Green engineering consists of environmental friendly, sustainable chemicals and processed whose use results in reduced waste, safer outputs, and reduced or eliminated pollution and environmental damage. Green engineering encourages innovation and promotes the creation of products that are both environmentally and economically sustainable. Green engineering typically consumes 40 – 50 percent less energy. The greatest environmental challenge facing our industries today is presence of toxic substances. Many organizations wants to turn green as a increasing number of consumers want to associate themselves with environmental friendly products.
Environmental Control systems : Energy storage systems (ESSs) and renewable energy sources are critical technologies that combine to create power generation and transportation. ESSs also need to be renewable. There are many types of ESSs including chemical,electrical, mechanically and thermal.
Air Scrubber : Wide range of scrubbers that are air pollution control devices used for high energy, liquid spray to remove various gaseous pollutants from air stream. The gases are removed either by absorption or chemical reaction process. Scrubbers are commonly used to help control emission of gases into the atmosphere. ECS has also developed other innovative technologies that underscore our commitment to providing total environmental solutions. And like everything, ensuring the highest level of confidence and protection in the industry today. ECS specializes in the application bio-remediation technology to reduce and/or remove organic pollutants from contaminants soil and groundwater. This process, in which in-house laboratory grown bacteria is safely introduced and managed at the site, is an effective, low-cost, reliable waste-management option whose benefits.
Green products design and packaging : A growing number of companies are making green IT initiatives a higher priority and have dedicated budgets for such projects as the pursuit of environmentally conscious strategies becomes more of a standard practice in the business world. Green engineering is the process and design of products that conserve natural resources, and impact the natural environment as little as possible. The term is often applied to housing, but it can be used for automobiles, Industries, lightings or any other sort of systems or device that require engineering, and in corporate sound environment principles. Though green engineering is some what more expensive in many countries, recognizing the value of such work, have begun to offer tax breaks, and other incentives to those who incorporate its use. Green engineering often have special training in the field, perhaps attending special classes to understand how materials and other components can be made in an environmentally friendly way. For example, engineering and architects concerned with home design may learn about the latest building materials and techniques. This may include the use of solar powered equipments, especially water heaters, solar lights, Wind energy or windows and other design elements.
Green employees & Jobs: There is a colorful distinction in the different kinds of jobs that exist in the market. White, Kakhi and blue collar jobs have become passé. Of late there has emerged another category referred to as green/low carbon. The phrase green/low carbon has become the most used phrase in the lexicon of politicians and corporate big wigs. For some it is emergence of new employment opportunities 14 | Roof & Facade Asia Asean Edition | July 2012
Why Go Elsewhere When The Grass Is Greener On Your Side !
in a limited job market and particularly for the environmental, green/low carbon jobs are crucial for combating climate change. It does not come as a surprise that what perhaps began as rhetoric to counter climate negativity is now developing into an area with extraordinary promises. In the United States green jobs are often defined solely as those related to renewable energy and energy efficiency. The ILO (International Labor Organization) refers to low carbon employment as “economically viable employment, which reduces environmental impacts to sustainable levels”. While some refer to employment in sectors that ‘make up the clean energy economy’, including energy efficiency, renewable, alternative transport and fuels as low carbon job. There are two types of employing green jobs i.e. direct and indirect. Direct employment includes jobs created in manufacturing, design, construction, installation, operation and maintenance of the different components of the technology. Indirect jobs created in the supply chain or consultants, professionals like energy auditors and energy managers who are key actors in the growth of renewable energy technologies as they play a vital role in the penetration of these technologies. The job of a welder at a wind turbine factory is considered as a green/low carbon job, but what about the factory’s accountant? The first is a direct job while the latter is an indirect job. India is emerging as one of the destinations with a huge low carbon employment potential. A study which assesses the potential of direct employment creation in India with regard to the transition of the energy sector to a low carbon pathway with a focus on the solar and wind energy sectors, notes that if government targets are achieved as scheduled, up to 243,225 jobs could be created in the wind sector by 2020. For solar photovoltaic, these numbers add up to 234,350
jobs. The study also notes that up to 10million jobs have been estimated by various studies in the biofuels sector if the government achieves its target of village coverage and industrial bio-fuel production. Though these numbers are indicative in nature, they put forth a strong case for low carbon employment potential that exists in India and how it can be one of the important co-benefits of investment green engineering or so called the renewable energy sector
Saving resources in Industries Green engineering are designed to be efficient in energy and water consumption, right from the outer design shell of the factory to the use of eco friendly equipments and materials. Green engineered factory also designed to incorporate systems such as rainwater harvesting, waste management, wind mills, solar panels to replace their energy guzzling alternatives to make factory more environmentally friendly. Going green is not just about cost. It is about using resources more wisely, as well as a shift in the professional attitude of architects, managers, corporate as well as everybody else. When the multinational corporations started coming in their initial directive to architects was to build the same structures they were used to elsewhere. Corporate, have been taken in by the ‘glitz’ of glass, which does not make either environmental or architectural sense in an environment like India where sunlight is not scarce.
i electricity A web based solution that allows factories to measure, analyze, control and save electricity – all that, over the web on connectgaia network containing inlet and outlet connectors, GPRS and Zigbee antennas, and sensors are installed on the consumers network. The unit draws information about the power consumption in the premises, at different areas or locations. It allows access of metered electricity data, and also allows the customer to remotely manage electrical consumption on their premises over the web, even though he may be on the other side of the globe. It is widely accepted that action such as construction of windmills, solar power and biomass plants will continue. This will not only have positive implications for energy security but aso have environmental, economic, and technological development.
Going green will be the mantra in the future.
Wood in Colour 'White' Maple flooring
American White Oak
Michael Buckley, MPhil, FIWSc
Wood species come in many colours although the perception of wood is often just ‘brown’. In these days of bright colour fashions, one can consider colour as well as ‘fit for purpose’ when specifying wood. In fact wood offers a wide palette of natural colours to inspire designers while also knowing that they are using a low impact 4/18/12 material. FA-Terreal Facade-19.6x29.7-OL.pdf 5:30:24 PM
Red: American Red Oak and Red Elm, Western Red Alder and North American Red Cedar are all colourful options for interior joinery and some for external cladding. Of all the red woods that exist, a favourite must be American ‘Black” Cherry which is, in fact, red not black and darkens with age, as do many species when exposed to the air and oxidation takes place. Many tropical species are also red, especially from Africa and Asia such as Padauk and Red Balau respectively. And although some consumers may have reservations about using tropical hardwoods their avoidance may eventually cause forests to be converted for other uses and therefore lost by default. White: White Maple from USA, Canada, and Europe, is one of a huge number of very pale species that are classified as white – some hard and strong as in white Ash, Sycamore, white Birch, and some soft as in European Poplar and American Aspen. White Oak however is a misleading name as it is anything but white, but more a variety of beautiful browns from gold to pale yellow. Softwoods from Russia and Scandinavia are often
nominally classified by colour as in Redwoods and Whitewoods. Yellow: There are so many yellow woods, which are not quite white. Tropical Ramin and Jelutong are also known for their uniform, almost white colour and American Yellow Birch mainly from the Lake States is valued for its colour and hardness. Many tropical species are yellow. Silver: This needs real consideration because left to its own devices, and subject to some architectural detailing, wood can turn a magnificent natural silver to give a long term, low maintenance, silver sheen to a building. Wood exposed to the elements will often turn silver within a year or two, especially Cedar, Oak and many tropical species. Black: No description of wood colours would be complete without black, such as Ebony Blackwood – an Acacia from Australia. Whereas other species such as American Black Walnut (Juglans nigra) are not really black. Brown: As mentioned, a high percentage of wood species are naturally one shade of brown or another Malaysian Balau, Meranti, Keruing, Chengal and Nyatoh being examples. Finally what about ‘green’ wood? One response might be that all wood is ‘green’ given its very low impact on the environment and its ability to store carbon, indefinitely in the case of heritage buildings and inheritance furniture. The great ancient Japanese temples are testimony to that. So when considering what to specify it may be good to remember the choice of colours wood offers to a global market currently very colour-conscious. Note: Michael Buckley is a Permanent Resident of Singapore and consults with wood industry clients in USA and all over Southeast Asia including the American Hardwood Export Council and Malaysian Timber Council.

Indonesia – Marching Ahead Increase in government spending to upgrade infrastructure of various sectors provides excellent growth opportunities for Indonesian construction industry.
onstruction activity in Indonesia, driven by investment in transport and energy infrastructure as well as industrial construction related to the country's growing mining sector, will be robust between 2012 and 2016, averaging 7.2% growth per annum. According to an estimate, the country’s construction sector will reach a value of US$78bn in 2013, up from US$38.8bn in 2008. Since Indonesia’s economy is better placed to wither economic downturn, the outlook is certainly among the most positive ones in Asia Pacific region. However, analysts caution significant risks to Indonesia's infrastructure and construction sector in the next two years despite the vast available opportunities, due to lack of improvement in the country’s business environment and sluggish global economy. According to Indonesia Bureau of Statistic, construction sector growth in the first half of 2012 was pegged at 7.3% showing the steady growth even during the adverse global cues. The realisation of national construction spending in this quarter has reached US$ 4.25 bn compared to last year’s US$ 3.9 bn. More so, infrastructure projects signed in 2011 amounting to US$ 3.8 billion are likely to augur the growth momentum of construction industry. In July 2011, three state-owned Chinese companies -- China Building
16 | Roof & Facade Asia Asean Edition | July 2012
Civil Constructions, Changjiang Waterway Engineering Bureau and China Foundation for Desertification Control had signed a memorandum of understanding for several infrastructure projects in East Java amounting to around US$3bn. In August 2011, Malaysian company Markmore Labuan had signed an agreement with Prodexim, a company owned by the South Sumatran provincial government, for the construction of a toll road in South Sumatra. The 137-km road, requiring an investment of US$882 mn, will connect Kayu Agung in Oki with Betung Banyuasin. These two investments highlight foreign interest in the sector which is largely dominated by domestic companies. However, on the negative side, the Jakarta administration in September 2011 had aborted US$630mn monorail project that had started in 2004. According to available information, the project was failed to move forward due to lack of financiers. The capital city has since move towards the development of a separate urban railway system.
Infrastructure is the key Increasing government spending on upgrading overall infrastructure, focusing on developing road, rail, energy and communication infrastructure, will provide growth opportunities in the Indonesian construction industry. Increasing population and urbanization will lead to a high demand for residential and industrial units. The country also wants to develop other cities besides Bali and Jakarta as tourist destinations. This will need development of all types of infrastructural facilities. Indonesia’s mining sector has also received large investments for developing rail networks and ports to transport coal. The government has earmarked US$250 billion to spend on various infrastructure developments till 2015. This will be funded by both public and private investment with more than 60% of the funding coming from the later. Another major development which would spur the infrastructure growth in Indonesia was the passing of Land Acquisition Reform Bill into law in last December. The Bill is designed to address several issues currently hampering government projects, particularly those relating to infrastructure. The Trans-Java toll road, for
instance, has been delayed significantly due to problems with land acquisition, with only 24 percent of the land required for the 650-kilometer highway purchased as of August 2010. The Bill will expedite land acquisition for public purposes while ensuring that these procedures conform to international best practices, put in place a comprehensive system for compensating landowners (with prices based on independent appraisal) and limit opportunities for speculation — at present speculators often buy land targeted for public projects, only to flip it to the government at a healthy mark-up. “Without improved infrastructure, Indonesia will not be able to break free from growth in the 6%-6.5% range, Muhammad Chatib Basri, Vice Chairman of the National Economic Committee of the President of the Republic of Indonesia, said recently, adding, “We need to grow by 9% because, beyond 2025, we have an ageing population.” According to Wijaya Seta, chief of the land acquisitions sub-directorate at the Public Works Ministry, the Bill would cut the time needed to start infrastructure projects in half. “Currently land price negotiations can last for more than a year,” he added. The Bill should help to spur investor interest in publicprivate partnerships for infrastructure development. With the National Development Planning Board estimating that the government needs to spend some $216 billion on infrastructure between 2010 and 2014, private sector involvement will be crucial going forward.
Housing sector Among the emerging South East Asian markets, Jakarta has shown robust growth in the residential market on the back of a strong economy registering 4.3 percent in the first quarter of this year. With the economy likely to post a strong growth during 2012, and a positive and stable outlook beyond, the property sector, according to analysts, looks set to continue its steady advance. The robust growth is likely to have positive consequences on the real estate market, as rising income has increased purchasing power for middle-and upper-income groups in particular, allowing them to invest in new residential properties. Growth is also feeding into demand for
commercial real estate as Indonesians’ disposable income has risen significantly, supporting the retail sector and the country’s growing mall segment. Furthermore, domestic and foreign companies are again looking to expand after slowing corporate growth during the global downturn, pushing up demand for office space, particularly for Grade A property, which has historically been in short supply. According to Todd Lauchlan, Country Head, Jones Lang LaSalle Indonesia, a leading global real estate research firm, “The first quarter increase is a continuation of a trend we have witnessed over the last 18-24 months in the Indonesian residential market, where price increases have been consistently pushed through by developers on the strength of robust demand levels. Demand is being driven by significantly increased affordability, and with record low interest rates, high consumer confidence levels and strong income growth we expect to continue to witness the rise of the Indonesian middle class.” However, majority of small and medium construction companies are feeling the pressure due to increasing fuel and input material costs. Despite high demand for residential units, prices are not going up as expected due to oversupply of housing units, high mortgage and interest rates (which have started to drop) and high inflation which discourages people from borrowing money. The existence of established construction companies and entry of new foreign contractors have led to high competition in the construction industry. With strong economy, expanding middle class, growing housing loan market and increasing demand for highend real estate in the residential, commercial and retail segments, the fundamentals for the local property market are solid. If the government can put an enabling legal framework in place to support investment and resolve issues related to land acquisition, this will give the sector a welcome fillip and should help to maintain sustained growth over the long term.
Retail sector Due to strong consumer confidence and rising household consumption, the retail market had seen active expansions in 2011. Local and overseas retailers have been actively expanding and opening new outlets
and existing projects, taking advantage of vibrant momentum. With the completion of five new retail centers – Grand Paragon, Kalibata city square, Tebet green, Kuningan city and MT Haryono square—totaling about 96,589 sq m and after the offset of two existing leased retail centers (Kalibata Mall and Kramat Jati Indah Plaza) being under renovation, the total aggregate supply of shopping malls of Jarkata in 2011 increased by 2.3 % to 3.87 million sq m. The largest supply was from South Jakarta, with 42 per cent of the total supply. The central business district remained the largest concentration of premium buildings which represented 86.2 % of the total existing supply in CBD. About 12 retail projects totaling 461,469 sq m are expected to be completed during 2012-13. The pipeline will consist mainly of rental shopping malls, supporting retail facilities within mixed use developments and the remaining being strata-title retail centers with the proportionate distribution area of 59% of CBD area and 41 % in the non-CBD area. South Jakarta will supply about 55% of the total new supply in the current fiscal. Last year in February, Indonesia’s largest listed integrated property developer and mall operator, Lippo, had secured a deal for space at two of its malls with Mitra Adiperkasa (MAP). Lippo agreed to lease 44,500 squaremeters of retail space to MAP, one of the country’s leading retailers, for its Kemang Village Mall and St. Moritz Shopping Mall, which are due for delivery in 2012 and 2013, respectively.
Major infrastructure projects
In July 2011, three state-owned Chinese companies, China Building Civil Constructions, Changjiang Waterway Engineering Bureau, and China Foundation for Desertification Control, indicated their intent to invest in East Java and signed a memorandum of understanding for several infrastructure projects amounting to US$3bn. This move once again highlighted the robust interest companies from stagnant domestic markets have for Indonesia. In August 2011, Malaysian company Markmore Labuan had signed an agreement with Prodexim, a company owned by the South Sumatran provincial government,
for the construction of a toll road in South Sumatra, Indonesia. The 137-km road, requiring an investment of US$882mn, will connect Kayu Agung in Oki with Betung Banyuasin. In September 2011, the Jakarta administration had announced that it is aborting its US$630mn monorail project, a project that had originally started in 2004. The project, which started in 2004, failed to move forward due largely to the lack of financiers. The capital city has since move towards the development of a separate urban railway system. In January 2012, PLN announced that it has identified 96 locations that are suitable for new hydroelectric power plants across the country, reports thejakartapost. com. PLN will develop 60% of the proposed facilities, with the remaining 40% to be offered to independent power producers (IPP) through a series of tenders. The power plants will have a total production capacity of 12,800MW. In February 2012, the Indonesian government announced that it will undertake a feasibility study for the proposed US$13.9bn Sunda Strait bridge project during 2012. However, the government said that it would only pay US$164mn, equivalent to 1% of the project's total cost for the feasibility study. The 31km bridge will run between Anyer on the island of Java to Bakauheni on the island of Sumatra and be the largest inter-island edifice in the country. Construction is scheduled to start in 2014 and the bridge is expected to be operational by 2025. The development of the project is led by the consortium PT Graha Lampung Banten Sejahtera. In March this year, PLN announced plans to launch a tender for the US$2.18bn Sumatra-Java high-voltagedirect current interconnected project in April 2012. Construction is expected to start in 2013, with completion scheduled for 2017. Once completed, the system is expected to distribute 3GW of electricity from Sumatra to Java and Bali Island, or vice versa. The project involves the construction of a converter station in Muara Enim (South Sumatra) and an inverter station in Bogor (West Java). The line will be used to supply power from South Sumatra to fulfill the rising demand for power in Java, with several coal-fired power plants being built in the former region. RFA

Bridging with BIM
BIM helps AECOM design and construct pedestrian bridge in Canada
ickering's new landmark, the $22.5 million pedestrian walkway over 14 lanes of Highway 401, is nearing completion. Being built by AECOM, a global provider of professional technical and management support services to a broad range of markets, the ‘Pickering GO Station pedestrian bridge’ in Ontario, Canada, has been designed and constructed using Building Information Modeling (BIM). AECOM was responsible for the full design, including architectural, structural, electrical, mechanical and civil engineering services while Teeple Architects Inc. provided preliminary design concepts for the project. Once fully completed, the structure will be wrapped in a metallic, meshlike skin, giving it a fluidic and organic appearance. The bridge is spanning more than 200 meters across Highway 401 in Pickering between the Pickering GO Station site to the south and Pickering Parkway to the north. GO Transit, a division of Metrolinx, is the regional public transit service for the Greater Toronto and Hamilton Area of Canada. The bridge is designed as a fully accessible pedestrian bridge with elevators at each end, as well as two elevators and direct stair access to the GO platforms at the Pickering GO station. The main structure is a series of linked steel trusses, with concrete floor systems and membrane roofing on a steel deck. The bridge features special effects lighting to illuminate the metallic panels at night, and though it will not be heated or cooled by mechanical means, it is designed to make use of passive ventilation.
“There were several challenges our team encountered during this project,” said Scott Patterson, BIM specialist and senior architectural technologist for AECOM’s design + planning practice, North America. “Challenges included doing construction work over one of the busiest highways in North America, meeting the requirements for full accessibility, meeting a tight construction timeline and incorporating unique and iconic design features that had not been attempted before, and that posed real design challenges with respect to constructability,” he further added. Revit BIM software was used in the design to model the complex shape of the bridge and to provide accurate geometry of the structure. The model was also used to demonstrate constructability issues and to simulate construction sequencing that was necessary to attain permits and approvals. In addition, Revit was used during the construction to utilise integrated project delivery (IPD) methods by communicating with the sub-trades and quickly getting design feedback for shop drawings and material quantities. “Without the use of 3D modeling generated from BIM, we would not have been able to convey the bridge’s complex shape any other way,” said Patterson. “Using Revit allowed us to undertake the complex design in-house, without the need for additional costs using an outside consultant.” The Pickering GO Station pedestrian bridge is the first in Canada to utilise a fully enclosed and fully accessible design mandate, and the first to utilise the perforated metal mesh material. “The Pickering GO Station pedestrian bridge project is a great example of AECOM’s continuous integration of technology software programs to offer solutions that add value to our clients’ projects,” said Jim Walsh, AECOM senior vice president and chief technology officer. The project is expected to be completed in August 2012. RFA July 2012 | Roof & Facade Asia Asean Edition | 19
Interview RFA: Which are the new emerging markets in Asia you are looking at for business expansion? Ghosh: Holcim Singapore operates within the local boundary, but Holcim Group has established its presence in the Asia-Pacific region for many years. We have an operational network that spans from emerging economies to mature markets, including China, India, Thailand, Indonesia, Vietnam, Bangladesh and Sri Lanka to Australia . With this strong network, we synergize each of our expertise to value-add in the large and infrastructure projects sector for our clients. That way, we work beyond the limitation of our Singapore boundaries. RFA: About your products and services… Ghosh: The competitiveness in the construction industry makes us realize that quality products must be paired up with quality service. To improve our customer service experience, we recently invested into a vehicle status control (VSC) program where all our customer sites are “geofenced” and mapped and our mixer trucks are tracked and monitored in real-time setting through a GPS tracking system and thus we craft the best possible route to ensure timely delivery to job sites. Holcim Singapore ‘s product lines are all application-based. Our two main product lines are ready-mixed concrete and drymix mortars. The drymix mortar line consists of the following categories: façade, flooring, concrete repairing, waterproofing and tile fixing. The ready-mixed concrete line is segmented into 4 strategic solutions:
Dr. Sujit Ghosh, Chief Executive Officer of Holcim (Singapore) RFA: Sustainable construction is the need of the hour due to fast depletion of resources. How does Holcim respond to the demand from construction industry for such need? Ghosh: Singapore is a resource hungry city-state and availability of raw materials is getting scarce. In our production, we have been implementing various initiatives to improve efficiency in the past few years. We embraced a ‘zero-discharge plant’ practice where we recover raw materials from production residue and reuse our water With Holcim Singapore’s strength in innovation, we have been persevering to reduce consumption of virgin materials in our product development. We have been successfully introducing sustainable alternative materials in previous years and strive to stay ahead in our innovation on sustainable substitute. RFA: You are spearheading concrete technology using recycled materials. Can you explain about it? Ghosh: It all started during sand crisis in 2007. It was a tough hit for us; especially we were supplying the mega project of Marina Bay Sands at that time. We took 20 | Roof & Facade Asia Asean Edition | July 2012
fancy of the abundance of copper slag, the shipyard industrial waste that was just disposed of in Semakau Island. Holcim took initiative to study it and realized its potential as the ideal substitute for natural sand. The usage of washed copper slag in our concrete also gives positive attributes such as higher compressive strength, heat-resistance and denser structure as compared to conventional concrete. Subsequently, we established a new product line which is now known as ‘Holcim Green’ concrete and has been applied extensively for non-structural and structural concrete use in various projects. The industry has also adopted the novel use of this sand substitute and now we can proudly say that not a single ton of this material goes to landfills anymore. Keeping our commitment to sustainable construction, we shall continue our efforts to find environmentally friendly alternative materials. To date, we have adopted fly ash (a by-product from power plant) and ground granulated blast furnace slag (in short known ‘GGBS’, a by-product from metal industry) into our concrete production. We recently just launched the first Centre of Excellence in Asia, through which we will further develop resource- and energy-efficient solutions to bring the industry more towards sustainable construction practices.
1. Productivity enhancement: The construction industry in Singapore has become challenging with more stringent requirements. We have to deal not only with limited availability of materials, but also with the shortage of manpower. We face the impact of labour shortage and increase of cost significantly. We took this challenge and offer solutions to improve efficiency at job sites. These solutions also shorten the project completion time and consequentially reduce the project costs. 2. Unique architectural finish: Apart from our main task to realize safe structures, we also understand the importance of aesthetics to make a conspicuous finish. We are able to custom-design our decorative concrete to fulfil the client’s landscaping and interior needs. 3. Special application: With Holcim's strong competencies in product development, we are able to alter the concrete elements and attributes. We have a multifarious range of customized concrete for special requirements of our customers. 4. Green concrete: Concretes that are made with recycled and alternative materials to support sustainable construction. These concretes contribute to the making of green building under BCA’s Green Mark Scheme. RFA: What are the new eco-friendly products we can expect from Holcim's lab in coming days? Ghosh: With the rewarding experience in the utilization of washed copper slag,
fly ash and GGBS, we are continuously exploring other sustainable alternative materials. At the moment, we are in the midst of implementing another wasteresource, incinerator bottom ash (in short ‘IBA’), into our next product lines in green concrete. To enrich the range of our product lines, we also offer new solutions to the Singapore market, namely, Conwood-an innovative and high quality eco-friendly wood replacement product that has a beautiful texture of wood and a durability of concrete. RFA: Can you tell us about the recently launched Singapore Centre of Excellence and aims and focal areas? Ghosh: The Centre of Excellence is our new facility that aims to gain better insights on our customer needs, especially with the increasingly stringent requirements in the construction industry, and to develop innovative application-based solutions that add value to our customer projects. Through the Centre, we invite customers to partake in developing and utilizing innovative solutions. The focal areas of product development are aligned with: Energy-and-resources efficient solutions; productivity enhancing solutions; innovative materials technology solutions; and customised solutions for special application needs, for the building and the construction industry. RFA: About awards you have won for eco-friendly products… Ghosh: We have an array of ‘Green Labelled’ products for our ready-mixed concrete and drymix mortar products. All of the products in our ‘Holcim Green’ line are Green Labelled. We have a special Green Labelled product for each of our drymix mortar product line. Internally, the Holcim Group also organizes the Holcim Global Commercial Awards to recognize best practice in the industry globally, in which our Holcim Green and Holcim Supercrete HS received the Bronze award in 2009, judged globally. RFA: Can you unravel the philanthropic side of Holcim (Singapore)? Ghosh: Holcim Group has a long history in sustainable development. What is widely known as corporate social responsibility (CSR), has been an integral part of Holcim’s operations. In 2008, we co-sponsored the screening of The Alps Exhibition and movie at the Singapore Science Centre’s IMAX theatre. The exhibition highlighted the contribution from Holcim Foundation for the Monte Rosa resting house on the Alps to provide shelter for the climbers which is a model for sustainable construction. 2012 is a special year for Holcim as we are celebrating our 100 years of our global operations. We commemorate this moment and the spirit of corporate volunteerism with the theme of ‘Together for Community’, where all Holcim employees around the world will be involved in community activity and contribute back to the society.
