Because of the impact on buildings energy performance, PAPIRUS will focuses on technologies and solutions that:

  • Reduce the energy losses through buildings opaque envelope;
  • Reduce energy losses in winter and solar gains through window in summer;
  • For light weight prefabricated panels with low specific CO2 emissions.
  • Provide good quality natural day-lighting;
  • Store thermal energy increasing the thermal comfort and shifting heating and cooling peak loads;


However, in the tenders the last two technologies have been left out due to lack of feedback from the market, lack of efficiency due to the high price for poor performance or lack of enough developed solutions that are not ready yet to be applied to construction sector. 

A report "State of the art of innovative solutions" has been elaborated in the framework of PAPIRUS. 

The report summarises the search and analysis of different innovative solution previously identified in the de DOW of the project. The idea is to look for materials, technologies or systems that present a considerable grade of innovativeness and whose presence among designers is limited or even nonexistent. The document initially presents a general analysis of the energy performance in the building sector in order to understand the construction reality that encloses us. Throughout the document more data related to this matter is presented in the chosen subcategories, e.g. fenestration typologies or current glazing properties. Secondly, there is an overview of potential solutions. In this overview of potential solutions five categories are suitably presented. Technologies will act reducing energy losses through building envelope, providing quality natural lighting, storing thermal energy, and using solutions that reduce the buildings construction phase related energy use.

Thermal energy storage

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.
