Energy storage systems (MESSIB)– ACCIONA
Case: Multi-sourceEnergy Storage System Integrated in Buildings (MESSIB). Thermal storage systeminstalled in a residential house located in Greece
ACCIONA is a large Spanish construction company and is the Coordinator of the MESSIB project funded under the FP7- NMP 2007: 126.96.36.199Resource Efficient and Clean Buildings. The MESSIB project began on 2nd January 2009 and is scheduled to finish on 28th February 2013.
The MESSIB Project is dedicated to developing, evaluate and demonstrate multi-source energy storage systems integrated in buildings and are based on new materials, technologies and advanced intelligent control systems to manage energy demand. Energy storage is a way to conserve energy in one form and release it when needed inthe same form or another form. Energy storage is used to store both thermal(heat and cold) and electrical energy by electrochemical, electrical,mechanical and thermal methods.
The CILECCTA software will be tested on new energy thermal storage system installed in the MESSIB demo house also known as I-SSB house,located in Greece (Mediterranean climate). This building was designed as atypical Greece residential house with two floors. In the walls of the house itwas installed a new phase change material (PCM) which is a part of the thermal storage system. The PCMs are capable of storing a large quantity of heat and are a kind of micro capsules that contain a latent heat storage material made from a special wax mixture. When the temperature rises above a certain level(indoor temperature) the material absorbs the excessive heat energy and stores it in phase change. When the temperature decreases, the capsule releases the stored heat energy again.
The MESSIB project offers a good opportunity for a large scale testing of the CILECCTA software to assess the environmental and economic aspects of new energy thermal storage system at an early stage of development.The analysis of LCCA and LCC by CILECCTA software demonstrated with MESSIB technologies will help in making future decisions in the field of thermal energy management of buildings.
