The present work evaluates the environmental impact of including phase change materials (PCM) in a
typical Mediterranean building. A Life Cycle Assessment (LCA) is developed for three monitored cubicles
built in Puigverd de Lleida (Spain). It is possible to control the inner temperature of the cubicles using
a domestic heat pump for cooling and an electrical radiator for heating: The energy consumption is
registered to determine the energy savings achieved. The aim is to analyze if these energy savings are
large enough to balance the environmental impact originated during the manufacturing of PCM.
Some hypothetical scenarios, such as different systems to control the temperature different PCM types
or different weather conditions are proposed and studied using LCA process to point out the critical issues.
Furthermore, a parametric analysis of the lifetime of buildings is developed.
Results show that the addition of PCM in the building envelope, although decreasing the energy consumption
during operation, does not reduce significantly the global impact throughout the lifetime of
the building. For the hypothetical scenario considering summer conditions all year around and a lifetime
of the building of 100 years, the use of PCM reduces the overall impact by more than 10%.The work was partially funded by the Spanish government
(projects ENE2008-06687-C02-01/CON, CTQ2009-14420-C02 and
DPI2008-04099I) and the European Union (COST Action COST
TU0802), in collaboration with the companies Synthesia, Honeywell,
and Cityhall of Puigverd de Lleida. The authors would
like to thank the Catalan Government for the quality accreditation
given to their research group (2009 SGR 534). The authors
also wish to acknowledge support of this research work from the
Spanish Ministry of Education and Science (DPI2008-04099/DPI
