The BP Headquarters at the Victoria and Alfred Waterfront
has been heralded for incorporating a number of Sustainability
measures, which include batteries of photovoltaic cells
on the roof, dramatic roof lights which serve a dual purpose
of admitting light into the building and allowing hot air
to escape. It also employs the use of metre-thick facades,
to moderate interior/exterior temperature differentials.
The architectural quality of the building is to be found
in the arrangement of the interior spaces - light-filled,
airy atria which form the major organising elements of the
building around which the office spaces are clustered and
the more public and semi-public facilities such as coffee
bars and meeting rooms are arranged. This hierarchy of spaces
is reinforced through the cross-sectional treatment of the
building, promoting legibility and transparency and allowing
natural light to penetrate from the roof to the lowest levels.
The exterior treatment responds to the Portswood Ridge context
in which the building is located and makes use of a restrained
palette of robust materials. It is considerably enlivened
by the play of light and shadow on the deep recesses of
the façade with its balconies, ventilator shafts
and sun-baffles.
