摘要：
This work proposes an environmental analysis based on the life cycle assessment (LCA) methodology. LCA was applied to determine if energy savings are large enough to balance the environmental impact caused during phase change material (PCM) manufacture and its installation on tiles. Inputs and outputs of each management stage have been defined and the inventory emissions were calculated by SIMAPRO v 7.3.2. Emissions were classified into several impact categories; climate change, human toxicity, acidification, ozone depletion, particulate matter formation and eutrophication. Three commercial PCMs, evaluated using five different Spanish weather climates, were studied to explore a wide range of conditions. The main results conclude that the use of PCM can reduce the overall energy consumption and the environmental impacts. This reduction is strongly influenced by the climate conditions and the PCM introduced. (C) 2012 Elsevier B.V. All rights reserved.
