Cities are considered to be energy consumers, because of transport and buildings,
which both make up almost 75% of the total energy consumption.
In France, the
most criticized buildings are the towers built during the 1960s and 70s.
paper aims to show an architectural concept that proposes to consider the
sustainable refurbishment of towers, instead of their demolition.
This concept is
called the Core-Skin-Shell concept.
The paper firstly describes the context that
leads up to a sustainable renovation of 1960s existing real-estate.
describes in detail the Core-Skin-Shell concept, which is based on a distinction
of the building functions into three “stratums”: the Core, which consists of the
structure of the building and brings thermal inertia; the Skin, which is a heat
shield and which ensures natural lighting and ventilation; and all around them,
the Shell, which both protects against outside threats and produces energy from
the sun or wind.
Thanks to this layering, this concept expects to optimize every
function of the building and to solve the two conflicting energy exigencies in
buildings: reducing the size of the envelope to minimize heat losses, and
increasing it to receive as much renewable energy as possible.
To study this
concept, a first work consisted of the analysis of a few architectural projects.
revealed some interesting potentials concerning energy production and losses,
comfort and even architecture and space qualities.
In conclusion, from this
analysis, this paper shows that the Core-Skin-Shell concept enables great
possibilities in energy saving and comfort in the case of tower refurbishment.
