A highlight of IGBC is a tour of exemplary projects awarded the BCA Green Mark, which is the de facto yardstick for sustainable development in the tropics. Participants will get to experience green buildings in operation.

There are 8 routes for delegates to choose from.  Here are some of the tour sites:

	Zero Energy Building @ BCA Academy BCA’s Zero Energy Building (ZEB) @ BCA Academy is BCA's flagship R&D project to showcase various advanced green building technologies, with emphasis on energy efficiency. The first of its kind in Singapore, ZEB will be grid-connected but will be net zero, i.e. not drawing energy from the grid over a 12 months period.  The 3,000-sq metre building is expected to be 60 percent more energy efficient than conventional buildings, and to be fully powered by solar energy.
	Changi Airport Terminal 3 Changi Airport Terminal 3 (T3) features a unique roof architecture which allows soft natural light into the building while keeping the tropical heat out. The one-of-its-kind roof design has more than 900 skylights with specially designed reflector panels which automatically adjust themselves to allow an optimal amount of soft and uniform daylight into the terminal building. At night, the skylights glow with artificial lighting delicately concealed below the reflector panels. The overall effect is a soothing ambience at all times of the day. Another key highlight of T3 is a 5-storey high vertical garden, called the “Green Wall”. Spanning 300 metres across the main building, it can be admired from both the Departure and Arrival Halls. The “Green Wall” is covered with climbing plants and is interspersed with four cascading waterfalls.
	Xilinx Asia-Pacific Headquarters Xilinx Asia Pacific Headquarters consist of a 6-storey office cum business park development located within Changi Business Park.  Xilinx uses high performance low-emissive double glazing unit for all external windows and full height ‘shop-front’ glass.  Daylighting into the office floors is maximised by limiting floor depth to not more than 10 metres.  M&E cores are carefully planned and located at corners facing eastern and western sun as heat buffers. Green features include innovative use of heat pipe and desiccant dehumidifier; extensive use of T5 lights in offices, car park and operational floors; use of motion detection system integrated with lighting in meeting rooms, toilets, carpark, staircases etc.; use of VSD for air conditioning system; use of solar cum heat pump hot water system; and collection of condensate water for landscape irrigation.
	Tampines Concourse This is a 3-storey office building with green building approach including design for sustainable construction, tapping natural elements and harnessing innovations. Tampines Concourse is the first in Asia Pacific to incorporate an innovative, indoor non-compressor fresh air cooling system for smart temperature and humidity control.  The system uses water as a cooling agent instead of ozone-depleting chemical refrigerants to cool incoming outdoor air through a natural heat exchange process.  Eliminating the need for a compressor, the highly energy efficient fresh air cooling system maximizes the use of fresh air and reduces energy consumption. It is capable of saving an equivalent of 21 tones of carbon emissions annually. Structural elements are all sustainable and of recycled materials. This project is the first in Asia to use green concrete in structural element and it contributes to reducing Carbon Dioxide (CO2) emission, pollutants emission and energy consumption. Other green features include double glazing and facade greenery to reduce solar heat gain, use of low Volatile Organic Compounds (VOCs) paint for all interior surfaces, use of solar tubes and light shaft to introduce natural lighting for atrium and toilets.
	9 Tampines Grande 9 Tampines Grande is an 8-Storey office building with one level of basement carpark. It is one of the first office developments to be awarded with the prestigious Green Mark Platinum Award. The use of Building Integrated Photovoltaic Panels (BIPV) with extensive use of PV and solar thermal panels on the roof make this one of the biggest projects in Singapore to harness solar energy. The unique Solar Air-conditioning system using hot water from the solar thermal panels and the efficient adsorption chillers is the first of its kind for commercial application in Singapore. The external facade is designed to provide a significant reduction in solar heat gain through the use of low E coated double glazing, insulated spandrel panels and horizontal sun shading devices.
	National Library Building Located at Victoria Street, the National Library Building (NL Building) is a 16-storey state-of-the-art library with three basement levels. The NL Building consists of two blocks, one to house library collections and the other to provide social spaces for library and public activities. The building also houses a 615-seat drama theatre.  As early as the conceptualisation stage, design considerations took into account the building’s impact both on the environment as well as its energy and water consumption efficiency.  Computer simulation and modeling was done to determine the best building orientation and configuration to buffer it from direct solar heat, while optimising natural ventilation and use of daylight. The NL Building also combines its passive design solutions with the adoption of environment-friendly technologies to create an environment-friendly building, to strike a balance in integrating both the passive and active approach to building design.
	City Square Residences City Square Residences (CSR) is set to take its place in the league of other iconic residential developments across the region as a cutting edge, environmentally friendly and sustainable development. The condominium units are strategically orientated toward north-south to minimise heat gain and reduce cooling load. The units come with large full height windows allowing superb natural lighting and ventilation. CSR incorporates numerous green innovations that include energy efficient lighting and water conservation practices such as the use of rainwater irrigation system. The use of solar energy is practised with the use of solar energy in light emitting tiles and bollard lightings. Motion sensors and Solatube for lighting up basements are also used within the development. CSR also places a strong emphasis on recycling efforts such as the setup of Green Corners for recycling and the use of environmentally friendly materials for construction; all done with the aim of providing residents better air quality and environment.
	Republic Polytechnic Republic Polytechnic is designed as an environmentally sustainable facility that encourages interaction and holistic development. The campus is oriented along a North-South and East-West axis for optimal daylight and thermal efficiency. It is the first building project in Singapore to make use of a purpose built Thermal Energy Storage (TES) System designed to reduce its energy bill substantially. The design of the Campus deliberately incorporates lots of greenery. This includes the Agora Lawn – 4 hectares of grassed area where trees are planted to provide shade and to minimise heat transfer to facilities below air-conditioned spaces of the lawn. The rooftop garden at the Promenade helps to reduce solar heat transfer, hence reducing the need for air conditioning. The multistorey carpark features a “green wall” and “green roof”, which reduce the effects of a “heat island” in and around the carpark.
	Bosch South East Asia Regional Headquarters This landmark building elevates seven storeys. The 0.98 hectare site is bestowed with a gentle slope rising from the road-frontage.  This physical attribute is capitalised by designing a raised entrance, thus freeing the space and vista at street level for a pedestrian-friendly entrance-court replete with waters and greens. The automated external aluminum-blind system, which operates under the command of a computerised programme, is twined to roof-mounted solar/wind sensors.  Fully covered with thin-film, mono-crystalline and poly-crystalline modules, the roof of the building becomes a contributor of power, as well as a test-bed for photovoltaic research.  The photovoltaic system feeds into the building grid, having a total power in excess of 90kWp.
	Poh Ern Shih Temple Poh Ern Shih Temple (or Temple of Thanksgiving in English) is located on the West side of Singapore.  It completed its first phase of construction in 2008. The temple takes advantage of Singapore's abundant sunlight by having three different kinds of solar energy cells on its rooftop. These systems are used for heating piped water, for generating electricity from solar energy and for collecting and magnifying the sunlight for use in the dark areas through reflective cum magnification mirrors.  With its breezy location, wind generators have also been erected to convert wind activity into electricity for use in charging in-house batteries and night lights.   Rainwater which falls on Poh Ern Shih is collected from roof run-offs and used for producing electricity via micro hydro generators, for passive irrigation of landscaping and for emergency supply of drinkable water through Natural Filtration & RO technology. Furniture is made from bamboo and non chemical fertilizers are used for landscaping.
	InnoVillage@SP (Singapore Polytechnic) The first of its kind in Singapore, InnoVillage@SP is an ecosystem for innovation at Singapore Polytechnic where academics, researchers and industry partners from all disciplines converge and innovate in Living Labs. InnoVillage@SP is designed to be a “bright green” building that is both intelligent and green.  Constructed using recycled materials from a prior development called Phase Z.RO, InnoVillage@SP incorporates many green features such as the National Solar Repository, the Green Gallery, photovoltaic panels, sunlight tubes and smart lighting that are displayed in an Interactive Eco Trail. This physical infrastructure will be layered over in phases. These layers of ambient intelligence, cloud computing and intelligent energy management will work in unison to create unique user experiences and manage energy conservation through these experiences.
	Twenty Anson Twenty Anson, designed by HOK International, is a modern Grade A office which sets new standards in sustainable eco‐friendly office design and development in Singapore. Daylight is a major design focus. Tapered ceilings at the perimeter funnel daylight indoors while the high‐performance glazing minimises glare and solar heat. External sun shading devices designed as internal light shelves shade the building while bringing glare‐free reflected daylight deeper indoors with less heat. Light sensors turn off artificial lighting when not needed. Thermal performance of the building envelope is enhanced by high performance low‐emissive glazing to reduce solar heat gain, glare, and noise. The podium green roof also reduces heat.  Thus, air conditioning loads and carbon emissions are reduced.  Water management strategies include rainwater capture through the green roof, for irrigation and greywater flushing, while efficient plumbing fixtures and sensors are installed throughout.
	Mapletree Anson Mapletree Anson is a premium 19-storey office building located at 60 Anson Road.  Mapletree Anson provides a low energy usage environment for businesses via its state-of-the-art environmentally friendly building technologies, resulting in an estimated energy savings of 2,282,597 kWh/year and water savings of 19,000 m3/year. The building has a high efficiency central cooling plant, with VSD (Variable Speed Drive) screw chillers, VSD for chilled water and condenser water pump, and VSD for cooling tower fan.  It has also incorporated CO2 sensor and demand control system to regulate fresh air supply requirement to indoor space, and Heat Pipes at the AHU to pre-cool the outdoor fresh air through cooled toilet exhaust air.  In addition, Mapletree Anson’s innovative application of photo-catalytic TIO2 nano coating in toilets removes odours and improves indoor air quality for users.
	One George Street One George Street is a 23-storey premier Grade A office building prominently located within Singapore's Central Business District.  The building is designed with energy efficiency, environmentally-friendly features and user comfort in mind. Its facade system provides shading for the glazing, with a design that allows optimum daylight penetration while reducing glare and heat transmission.  Sky gardens on levels 5, 12, 15 and 22 reduce urban heat-island effects and cooling load required in the building. Heat pumps with higher coefficient of performance are used for the heating of swimming pool instead of conventional electrical heaters or gas boiler.  Electronic air filters are also installed at the pre-cooled air handling units to achieve higher level of indoor air quality.  The building is also structurally designed to allow future extension floors, which eliminates the need to demolish and rebuild in the future.
	Marina Barrage The vision of Minister Mentor Lee Kuan Yew, Marina Barrage spans the mouth of the Marina Channel, creating Singapore’s 15th reservoir, and its first in the city. A 3-in-1 project, the barrage creates a new water supply, acts as a flood control mechanism, and offers a venue for water-based recreation. At the same time, its iconic main building fuses function with aesthetics, and opens up a haven of recreational opportunities for the community. Marina Barrage is designed, constructed and operated on green principles, exemplifying Singapore's holistic approach to sustainable water management. The Green Roof acts as natural heat insulation for the building, while double-glazed glass panels reduce heat penetration and minimise energy consumption. The Solar Park generates 50% of daytime energy needs for indoor lighting and power points, while a rainwater collection system harnesses rainwater for irrigation. In addition, the Sustainable Singapore Gallery educates the public on environmental and water issues through multi-media displays.
	People’s Association Headquarters The People’s Association Headquarters (PAHQ), located at 9 King George’s Ave is the former Victoria School.  It has a mix of conserved and new buildings. The PAHQ’s design placed great emphasis on the environmental sustainable design considerations since its preliminary planning stage.  Concerted efforts were made to naturally ventilate the double-volume entrance foyer and 5-storey central atrium.  The north-east orientation of the buildings encourages the prevailing wind to cross ventilate through the entrance foyer and central atrium.  The openings in the central atrium also promote stack effect, capitalising on the pressure differentials for air circulation within the atrium.  Photovoltaic panels were integrated with the skylight design to harness solar energy and also to allow daylight penetration to the atrium below. Computational simulation programme was used to analyse shading and enhance energy efficiency.  Extensive landscaping such as the open field, internal courtyards and roof gardens helps to lower the ambient temperature.
	Samwoh Building Partially funded by the MND Research Fund, the objective of this project is to conduct a full scale study on the use of Recycled Concrete Aggregates (RCA) in structural concrete for building structures.  It involves determining the optimal design of concrete mix with RCA for constructing an actual three-storey building.  Extensive instrumentation is carried out on the building to monitor the structural performance of the RCA material. The building is the first in Singapore and one of the few in the world to be constructed using concrete with high dosage of RCA.
	Samwoh Concrete Waste Recycling Plant In line with the government’s goal to achieve environmental sustainability, Samwoh has set up a Concrete Waste Recycling Plant to recycle construction and demolition (C&D) waste.  The plant comprises state-of-the-art facilities to process the C&D waste into recycled concrete aggregate (RCA) which contains mainly aggregate and cementitious materials.  The processes include crushing, screening, removal of metals and foreign materials and sieving into various sizes.  The RCA is compliant with the latest Singapore Standard and can be used for construction applications such as road construction and Eco-concrete.
