The new apartment building in Vaduz, Liechtenstein has been designed as an active energy building. Details of the project can be found at http://www.architectour.net/opere/opera.php?id_opera=6869&nome_opera=Marxer%20Haus&architetto=Falkeis%C2%B2architects&language=1 and http://www.puretemp.com/pcmatters/inspired-by-nature-marxer-haus-takes-wing-in-liechtenstein. As well as many other sustainable features, the apartment block utilises movable “wings”. These climate wings contain 1.4 tonnes of Rubitherm PCMs enclosed in aluminium tubes. Four wings on the western side contain PCMs for heating (31oC M.Pt.) whilst three wings on the eastern side contain PCMs for cooling (21oC M.Pt.). The wings fold back against the building when not in use.
