Cost-effective rehabilitation of public buildings into smart and resilient nano-grids using storage

About the project

The high energy consumption in the building sector, that is primarily fossil-fuel based, and the limited availability of the national electric grid in some remote or rural areas of the Mediterranean region call for new solutions that ensure stability and power quality of energy provision and higher penetration of renewable energy sources. In this context, BERLIN aims to implement cross-border pilot measures to support innovative and cost-effective energy rehabilitations in public buildings based on the nano-grid concept, the building block for smart micro-grids. The project will focus on increasing grid penetration, combined with energy storage and demand-side management, along with enhancement of energy efficiency in buildings. The goal is to reach high levels of self-resilience in public buildings and to make them greener, smarter, more innovative and sustainable. The project will implement 8 energy rehabilitation pilot actions which bring effectively together photovoltaic, energy storage, smart grid elements, home automation, etc. to achieve a self-sufficient nano-grid.

What will be improved?

In the mid-term, the project will achieve a reduction of energy consumption and CO2 emissions at the level of pilot buildings. Thanks to the case studies, tools, developed guidelines, the project hopes to foster replication in other Mediterranean/EU regions and enhanced interest and capacity of public authorities in building energy retrofits. In the long-term, the project will encourage a widespread policy adoption for high photovoltaic grid penetration and high levels of self-sufficiency in buildings. It will boost SMEs competitiveness, R&D growth, investments in photovoltaic grid integration, interest from local building professionals to train in new innovations for high efficient buildings, and business and job opportunities in building retrofitting.

Who will benefit?

  • Energy stakeholders (policy-makers, investors, distribution system operators, regulatory authorities, energy consultants, photovoltaic installers)
  • Local, regional, national authorities 
  • The scientific community 
  • Building users

Expected achievements

  • 8 case studies on the photovoltaic, energy storage solutions and demand side management hybrid technology
  • 4 country-specific recommendations to stimulate the uptake of photovoltaic, energy storage solutions and demand-side management 
  • 2 tools developed for renovating public buildings using photovoltaic, demand-side management and energy storage systems
  • 8 pilot actions in buildings in 4 countries
  • 3 cost-effective technologies in public buildings optimally integrated
  • 5 public institutions supported towards the adoption of cost-effective policies to increase the use and local consumption of photovoltaic energy
