The use of new solutions that are much lighter and that have the capability of storing energy and releasing it when it is needed may help to improve this indoor air quality and reduce buildings energy consumption. New solutions with phase change materials (PCM) within building Tª range that contribute to stabilize indor air temperature and that building’s reduce energy demand in at least 20% are suggested.
These materials have the availability to change their state within the operation temperature ranges of buildings releasing/storing high amounts of energy. Depending of the temperature in which this phase change takes place, these solutions can be suitable for cooling or heating dominated climates.
Thermal energy storage on the other hand, can be promising solutions for off peak electricity energy storage as renewable electricity production can be forecasted and smart grids are introduced.
Some examples of these type of solutions that can be integrated in buildings are as follows:
- Plasters or wallboards with microencapsulated PCM in theirmatrix,
- Tiles with PCM,
- Macro encapsulated PCM connected with buildings HVACsystems,
- Windows with PCM.
With new buildings being lighter, these types of solutions may help to satisfy more demanding comfort standards. On the other hand, as far as renewable energy power supply is increasing and smart grids are becoming more common, the thermal storage may represent a huge opportunity for peak load shifting and reducing procurers’ energy bills.
The performance validation of these products in different type of buildings and climatic zones (heating and coooling demand), may help to foster these type of solutions within EU.
