The Demonstration

Eight demonstrators are included in SunHorizon.  The SunHorizon project is a “Demonstration-to-market” project aiming to identify the ultimate technical and non-technical barriers to be overcome before the commercialization of the products in 2023-2025. In order to achieve this goal a robust and wide EU demonstration campaign will be performed (18 months in order to have two compete heating seasons monitored for benchmarking) installing SunHorizon TPs in different type of buildings and climates, testing the hardware, smart monitoring and management tools in different contexts and countries. Demo sites will be also open for demo visits during SunHorizon Open Days part of the project dissemination plan.

SunHorizon demonstrators will tackle the demonstration of optimised, cost-effective H&C components and their coupling (i.e. technology packages) in different operational (TRL 7) environments across EU

  • Cold climate (C): Riga (Latvia), Berlin and Nürnberg (Germany)
  • Average climate (A): Verviers (Belgium), Le Bourget-du-Lac (Francia), Madrid (Spain)
  • Warm climate (W): San Lorenzo de Hortóns and San Cugat del Vallés, (Spain)

The spatial distribution of the demo cases, together with the consideration of most common residential and tertiary building typologies, will ensure a swift and straightforward replication of the SunHorizon results all across EU
