st 1 International Symposium Workshop on Low Carbon Buildings in China , April 2, 2010 Professor Jo Darkwa 教授 Director, Centre for Sustainable Energy Technologies (CSET) 可持续能源技术中心主任(CSET) CONTENT 目录 • SITUATION IN CHINA 中国的现状 • EXAMPLES OF LOW CARBON TECHNOLOGIES AT CSET • 在CSET中的低碳技术 • CONCLUSIONS 结论 1990-2030年，世界各地区的二氧化碳排放量 CO2 per capita per country 各国人均二氧化碳排放量 USA = 19.1 CHINA =4.6 ENERGY IN BUILDINGS –CHINA 建筑中的能源—中国 • China produces 2 billion square meters of new buildings every year - equivalent to about 80,000 new skyrise buildings annually. 中国每年新增20亿平方米的新建筑，相当于每年新建8万座摩天大楼。 • Energy consumption in China’s building sector has increased more than 10% each year for the last 20 years and now represents 25% of total energy usage in China. 中国建筑领域能耗在近20年保持每年10%的增速，目前已占用了全中 国1/4的总能耗。 5 RESEARCH AND DEMONSTRATION BUILDING THE DESIGN设计 • The building has two parts (semi-basement and the tower) 该楼有两部分（半地下室和塔楼） • The semi-basement area is partly glazed on east and west sides in order to maximise the penetration of natural light and avoid the direct solar radiation. 半地下室在东西侧安装了玻璃，既能最大限度利用自然 光源又能避免太阳直射。 • The tower has been carefully insulated and protected from winter cold wind and strong direct summer solar radiations. 塔楼具有良好的隔热性能，能有效阻隔冬季的寒风和夏季强烈阳光的 直射。 • The opaque parts of the building consist of concrete walls which are externally insulated and cladded. 大楼不透光的部分是外表面隔热并 由金属包裹的水泥墙。 LOW CARBON TECHNOLOGIES 低碳技术 • Solar PV and Wind mill for electricity • 太阳能和风力发电 • Geothermal Heat Pump for cooling and heating 地源热泵制冷和取暖 • Green roof tec
