Starting point Provision of one of the largest and most important pavilions at the EXPO, the so called “EXPO Centre”, with domestic hot water. The centre covers an area 350 m long from East to West and 140 m wide from North to South (a total construction area of 140,000 m²). The solution has to provide and guaran- tee a huge amount of hot water and meet all different kinds of requirements. The requirements on the new system The solar panels produce hot water for the entire EXPO Centre, including the main kitchen and all sanitary facilities. After the EXPO, the building’s complete infrastructure will be used as a conference centre. This means that the system must be capa- ble of providing sufficient volumes of hot water for confer- ences and full-occupancy events. On the other hand, it must not overheat if there are no events in the centre for a few days. The ELCO systems have met this challenge successfully. They are completely reliable and very easy to maintain. Another very important point is that the outside wires and accessories of the solar tubes in the installation on the roof of the bus sta- tion are not visible to EXPO visitors. Aesthetically, the project is seamlessly integrated into the structure of the main building, the EXPO Centre. In addition, the shade provided by the in- stallation ensures pleasant temperatures in the waiting area of the bus station in the humid heat of the Shanghai summer. The new system The solution is a solar water-heating system with a total area of 310 m² which is sited on the peripheral parking roofs around the EXPO Centre. Its heat source is gas-fired boilers, and its daily hot-water capacity is 28 tonnes. • The system uses solar power as its secondary heat source. • There are two heat-collecting areas and four independent heat storage and supply sections. • The system is the only solar plant constructed for one of the five main pavilions, which will remain in use after the exhibition (the so called “remaining pavilions”). So the system is used to provide domestic hot water during and after the EXPO 2010 exhibition. It is recognised and praised as one of the most important en- vironment-friendly, renewable-energy projects after ELCO’s project in the Olympic Village in Beijing. True to the theme “better city, better life”, the project with its new environmental solution system reinforces the idea of the 2010 exhibition in Shanghai and promotes the aim of its customers perfectly.
