Shanghai Jiaotong University Research Solar Technology of Architecture Energy Saving
戴上一顶能“吃光”的“太阳帽”，就可以使这幢大楼节能六成以上。2005年8月23日王如竹教授课题组承担的“再生能源建筑一体化技术与系统研究”通过了结题验收。
据介绍，150平方米的“太阳帽”所收集的能量，可以满足460平方米使用面积所需的采暖和空调制冷，还可以在房间内每小时“吹”3次自然风，并提供15吨生活热水。在上海地区气候条件下，这个“太阳帽”可以承担年运行能源的60％以上。
一年四季中，这顶“太阳帽”的功能有所不同。夏季天气晴好时，“太阳帽”吸收的热量可以驱动“太阳能吸附式空调”为房间长时间制冷；冬季利用太阳能热水供应地板辐射采暖系统，能够提供大空间办公室的供暖；在春秋过渡季节，则可以利用太阳能热水加热太阳能通风通道的空气，强化自然通风，使自然通风量提高1倍以上。
On 23,August 2005 the topic of technology and system research for integration of renewable energy resource and architecture is checked and accepted. RuzhuWang professor topic group assumes it. The topic is about that a building in a sun hat eating sunlight would save energy more than 60％.
It is introduced that the energy that is gathered by a 150- square meter sun hat could be used in the following aspect: heating and refrigeration for an area of 460 square meters; providing 3 time natural wind in a room; providing 15 tons life water. In the climate condition in Shanghai,the sun hat can assume more than 60％ energy per year.
The sun hat has different function all the year round. In summer,the heat absorbed by the sun hat can drive a solar air condition to keep refrigeration long time for a room. It uses solar hot water to keep floor radiate heating system that can support heating for large space office in winter. In seasons of transition,spring and autumn,the sun hat uses solar hot water to heat air in the solar aeration channel,which raises quantity of natural ventilation one time more than average level.
