ABSTRACT
This office building project constructed in 1995 for British Gas Properties is, in addition to its low-energy strategy, of particular significance for three reasons. First, the building was and, at the time of writing, remains the only speculative commercial office building of this nature. Second, the building is constructed on a previously contaminated site close to Leeds city centre. Third, the mixed mode strategy for the building is a particular response to the urban location of the site and, for example, does not rely upon the opening of external windows to maintain comfort conditions within the office space.
