HYBUILD

The overall objective of the HYBUILD project is the development of two innovative compact hybrid electrical/thermal storage systems for stand-alone and district connected buildings. The two concepts will be developed for ensuring comfort condition in residential buildings located in two different climates: one for Mediterranean climate, where cooling season operation is particularly critical, and another one for Continental climate, where criticalities mainly concern the heating season operation. Both systems will be able to efficiently cover also heating and cooling demand respectively.
The aforementioned systems aim to enhance the penetration of renewables in the building sector, by efficiently converting solar energy to electricity (via photovoltaics) and heat (via a DC driven heat pump) and storing the produced energy either in batteries (as electricity) or in high density latent thermal storage modules (based on PCMs). Especially for the Mediterranean concept, solar thermal collectors will drive a two bed sorption chiller, providing an extra storage module or increasing the electricity-to-heat conversion efficiency.
