The global energy crisis has caused a double effect. On the one hand, users are increasingly aware of the energy cost they face. On the other hand, public administrations have become aware of the importance of limiting energy consumption in buildings as a way to combat climate change and reduce the energy dependence with the climate. This situation supposes a great opportunity for innovative constructive solutions with an energetic behaviour that surpasses the traditional approach of reduction of the transmittance. In this work, studies are presented to obtain potential of a new solution thermally activated with two innovations with respect to those existing in the market: its activation is done by hot / cold water produced by renewable systems; and its concrete structural element in addition to having coupled the heat exchanger presents an innovative mortar doped with PCM microencapsulated phase change material.

The objective of the work is to develop an algorithm that automatically manages the activation of the heat pump in response to the most appropriate strategies according to the pricing and operating conditions. It is interesting to see if a balance can be reached between the cost savings, the increase in energy consumed, the thermal comfort of the occupants and the contribution to the reduction of the peak loads. The study shows different results and conclusions, highlighting the important influence of various factors on the results obtained, such as user behavior, constructive quality of the building and electric pricing. Connection with a future renewable production can maximize the economic savings; it is interesting the use of buildings as thermal storage of unused photovoltaic surplus. Finally, the possibility of combining these measures with electrical storage and with the possible arbitration linked to renewable production.
