Integration of CCHP microgrids in NZEB with critical loads under high PQR requirements, a position paper

In recent years, many projects have been developed to reduce the energy consumption of buildings, both from the point of view of energy efficiency and the integration of renewable energies. However, few projects are related to the problem of integrating DER in environments dominated by high-tech equipment, the so-called critical loads: data centers, railroad stations, airports, and hospitals. The European Interreg Sudoe IMPROVEMENT project aim is to renovate existing public buildings where critical loads predominate, converting them into nearly zero-energy buildings (NZEB), and for this purpose, it integrates combined cooling, heat, and power (CCHP) microgrid with renewable and other distributed energy resources (DER) like hybrid energy storage systems (ESS). With still one year to go before the end of the project, the consortium partners present in this position paper the latest progress of their respective work packages to date. (c) 2023 The Author(s).

Automated summary

In recent years, there have been many projects aimed at reducing energy consumption in buildings, particularly in environments dominated by high-tech equipment. The European Interreg Sudoe IMPROVEMENT project aims to convert existing public buildings into nearly zero-energy buildings by integrating different energy resources.
