Choosing to build with hemp
To pre-empt the ever more stringent construction standards, the architecture firm Dumont & Legrand is open to working with experimental types of
materials, as we discover in this project using hemp concrete, a composite
that differs somewhat from those we usually report on. Of course, composite
materials as such also have their attention, but the lack of knowledge and
communication on the subject are obstacles that the composite industry
must work to overcome if it is going to become established in the building
& construction sector.

S

ince the Kyoto agreements, there
is international demand for a
"Factor 4" approach, i.e. reducing
carbon emissions by 75% to avoid the
greenhouse effect facing us today.
Standard concrete is a solution that
combines economical and mechanical
advantages, since it provides high mechanical strength and is cost-efficient.
While it remains the easiest solution
for building both fast and well, the
entire chain involved in concrete production makes it the material with the
highest carbon emission. Concrete is
very energy intensive, requiring ships,
factories, fuel, blast furnaces (for both
the steel and the lime) and intensive
human activity. You also need sand for
concrete, and sand is becoming scarcer
worldwide.

Grégoire Dumont: "Our agency installed in Paris and Bordeaux has a limited economy, with average-size projects.
Our access is relatively restricted compared to the large groups, and the use of
composite materials is more often than
not either beyond the customer's budget
or not requested, although we are free to
guide them in the direction we wish. At

the scale of my small agency, what can we
do to comply with the new standards? How
can we affect the phenomena? I'm an architect, and I'm always looking for specific
products or solutions to play, work and innovate with for our projects."
Our avenue of research:
non-traditional materials
"We, Dumont & Legrand Architectes associated with the engineer Laurent Mouly,
are turning to biosourced materials, which

emit far fewer emissions in their life cycle than concrete, and are produced for
construction purposes, like hemp (agricultural) or wood ( forestry). Both are
beneficial during their growth period
because they absorb carbon.
We are shocked by today's (poor) building quality and want to fight against
that. In recent years, we've turned to
wood and brick materials. Choosing to
build with hemp for its architectural and
environmental qualities always
