In this study, a novel trigeneration system is conceived to produce heat and electricity and to provide cooling for the health treatments and touristic facilities of a spa, based on the natural hot water and solar sources. The power generation components, individually considered, are commercially available ones, but their novel combination and the complex power flow management represented a challenge. The proposed system is composed of a low‐temperature driven adsorption chiller, thermally activated by a low enthalpy geothermal source, and by hybrid photovoltaic/thermal panels.

This paper deals with the potential role of new hybrid energy systems application along with the heating share concept. It analyses the possibility to develop new plant refurbishment strategy so as to promote the deployment of small scale smart energy systems. Up to now, many new technologies have been implemented can be used for achieving the NZEB objectives. The paper clears up how is possible to share the heat for a small group of dwellings arranged in a single lot.
