This is interesting proposal awarded a special mention for 2010 eVolo skyscraper competition. This project comprised of a system of gutters to catch as much rainfall as possible. The water captured and processed by the building may be used for flushing toilets, feeding washing machines, watering plants, cleaning floors and other domestic applications. Initially, in designing the tower, the students focused on shaping and modelling the surface of the roof to optimize the rainwater collected. Yet upon working with the roof system, the students developed the skin treatment to make the building transform into a cohesive rain collecting machine.
I think is a very good design concept. I certainly believe such can be a residential building and the water catchment is a very good alternative for water consumption. I just hope the façade concept will capture rain water as the design shows.
Still a great concept and i like the form. However, storing the water in a basin at the bottom of the tower will require a lot of additional energy to pump it back to up for use on higher floors. Retaining it closer to the top (as it looks like may be the case for the water in the catchment on the roof) will allow for gravity to do the work.
