|Here are thumbnails of two schemes, each of|
which were presented in 3 A0 panels.
The students of the unit submitted 9 schemes, and 7 were chosen as finalists, and the remaining 2 were highly commended. Only one other scheme from the UK was included in the total of eight finalists.
Phil and I set the students the task of designing the upper residential sections with ZERO energy cost from any form of burning - no gas, oil or direct electricity! They have all designed apartments with heating based on the Surya interseasonal technology of my Peveril Solar house, with solar thermal panels on the south elevation, and large thermal stores on every floor, or every fourth floor, and underfloor heating from heat pumps in each apartment.
At a height of 200 metres, it is too distant to send heat to and from thermal stores deep below the underground parking so the geothermal stores have to be 200 metres high too. As we could not use vast amounts of clay at that height, we would use large water tanks or stores of PCM blocks. The stores have to store an entire summer's heat, and it is clear from my own system that there is additional real-time heat in equinox and winter to avoid total cooling of the store during winter. More of this later. At the second stage, we will get engineer colleagues to validate the quantities required.
We shall be showing these schemes on our model of New York - all nine of our designs - at Ecobuild 1-3 March 2011, Excel Centre in east London, on one of the largest stands of the show. Please call in!
The best three from the UK will be invited to Prague for the final in May, so at least 2 of our groups will have an invite and a prizes.
April 2010 Postscript: the one illustrated top won the FIRST prize in the UK stage of the competition, and the one illustrated below came 4th as decided by the competition judges, but was declared FIRST choice of the public attending EcoBuild.
