2012伦敦奥运会的十个“第一次”

The first completed venue of the Olympic Park was the Velopark’s Velodrome, a giant indoor cycling track. Fitting the “green” theme of the games, the venue is outfitted with rooflights to cut back on artificial lighting, and natural vents to minimize air conditioner usage. Also, the roof is designed to collect rainwater as a supplemental water source.
奥林匹克公园中最早建成的就是自行车赛车场——一个巨型的室内自行车赛道。该场馆与本届奥运会“绿色环保”的主题相呼应，采用了采光屋顶以减少使用人工照明，使用自然通风也减少了空调的使用。同时，房顶的设计使其能收集雨水来作为补充水源。
