[EN] Energy save in buildings can be reached by several ways: Walls isolation, air
conditioning or efficient ventilation are some examples. In this project, studies of
new window systems are going to be done, comparing all the possible solutions
to conclude which one would be the best in order to reduce the overheating in
rooms.
Phase Change Materials (PCM) are introduced as innovative materials which
can absorb heat due to its properties. Research in these window systems will
determinate whether this material can reach significant improvements or not.
Japan, due to its location, suffers this summer overheating. With range
latitudes between 31º (Makurakazi, 31º 15¿N), and 45º (Wakkanai, 45º 28¿N)
(only Honsh¿ island will be considered), extreme hot conditions are affecting
this island due to the Sun radiation.
To compare these window systems, Japanese weather conditions will be
considered, since they will be implemented there.The main aim of this project is to quantify how much incoming energy will be
avoided within the use of Phase Change Materials. Results will be provided and
compared within heat transfer procedures, obtaining every moment the
temperature in different window zones.
Results will be used to be compared with results obtained in an experimental
project. The analytical procedure will be useful to modify different window
elements, obtaining with it sufficient data to determinate whether a Phase
Change Material (PCM) achieves an energy safe in the life cycle of a building.
For this purpose, six different windows will be compared, in order to determinate
the efficiency of this system.
The hottest day in the data base will be used for this purpose (19th July).
