The Trellick Tower as other constructions of the 70's has some deficits in its environmental performance. The principal target of this work was to analyse it from an energy consumption point of view and develop ideas to improve its performance through changes in the architecture and construction. Two flats were monitored: one duplex on the 24th (flat 170) floor and one single story on the 21st (flat 167). Both of them are corner flats in order ro establish comparison between them. 

The main tools used to achieve this target wereEcotect, Radiance, Tas, climate dataloggers, surface temperature tool and daylight levels.
