Abstract
In order to ensure that Italian building regulations comply with the Kyoto
Protocol, we aim to propose a classification method for building materials.
Actually, we aren’t able to choose materials comparing their energy and
environmental value. A database of building materials based on the LCA system
is not yet available (national research \“Genius loci”), but the rules about low
energy building are mostly completed; we omit the rules and methods
concerning how to choose materials in low energy buildings. Using a national
LCA based database we aim to classify building materials into several classes
and to define the possibility of choosing materials, balancing the environmental
class and their weighting in the building. In this way we will provide the
possibility for choosing materials based on their contribution to the
environmental impact of the building as a whole. The idea is not to force
designers, architects or engineers to choose all materials for a building which
belong to the best class, but to force them to balance materials to guarantee that
all of them together will produce a low environmental impact. To do this, each
material has to be weighted on its LCA results and on its quantity. This method
will agree with the spirit of the Italian law about low energy design and give to
the designer the right flexibility in choosing materials, respecting a global
environmental evaluation of building. It will also be a possible item for the
implementation of the D. Lgs 192/05 that apply to EU Directive 2002/91/CE on
the energy performance of buildings.
Keywords: building, material, legislation, policy, energy, LCA.
