ArchDaily announced the winning proposal for the 2012 MoMA PS1 Young Architects Program (YAP) earlier this month. In order to bring you full coverage of the annual competition, we are featuring the other four creative designs that competed against HWKN’s Wendy. Virtual Water, a collaborative design brought to you by UrbanLab, endrestudio and Method Design, formally manifests what is hidden in plain sight: RAIN. The project reveals and plays with thousands of gallons of summertime rainwater that would otherwise be discarded from the PS1 courtyard. Virtual Water refers to water hidden in everyday products. A pair of jeans, for example, has a 3000 gallon Virtual Water footprint because 3000 gallons of water are consumed in the various steps of its production chain (growing the cotton, dyeing the fabric, etc).
