Report on baseline and boundary conditions of SunHorizon demo sites, including monitoring aspects

The current D6.1 report 1 about T6.1 activities is aiming to gather relevant information from the 8 demo sites visit and available historical data to feed appropriate inputs in TRNSYS modelling task 2.4 and detailed engineering of the demo sites in following Task6.2. SunHorizon participants are elaborating technology packages to be deployed during "WP6 Demonstration" in the 8 demo sites across Europe, to meet the requirements related to the different climatic conditions and different building typologies. The organisation of the partners according to their roles in every demo site demonstration work referred as T6.1.x has been regularly updated since the beginning of the project. For each of the 8 demo sites managed in SunHorizon, the T6.1 work focuses on the analysis by simulation/support partners of the data collected by every demo responsible during T2.1. The main objectives are: - to extract and to summarize the relevant information for the building and energy system modelling in T2.4 (moderate level of detail for overall energy assessment), relying on the KPI definition in parallel in T2.3 (D2.4 report), - to help the technology manufacturing partners to understand the boundary conditions of existing heating/cooling system for the partial or full scope of the Technology Package (TP) new system to be deployed in the building, - to highlight any specific technical, economical, regulatory requirement that the TPs have to face The D6.1 report illustrates the main activities followed by each T6.1.x demo group during this task T6.1 until delivery of the current D6.1 report at M18. In parallel to WP4 work related to on-site TP Monitoring, a sketch of the monitoring to be installed along the TPs at M24 was issued by the 8 groups during T6.1.x time since it has to be performed during the general preliminary definition phase of the project. This preliminary monitoring plan will be refined further with Schneider Electric as monitoring solutions suppliers during the next T6.2 detailed engineering phase lead by RINA. The 8 demo specific sections of D6.1 report contain: a general description of the demo case, local weather characteristics, building geometry, building use and occupants, existing heating and cooling systems, specific requirements for the coming TP integration in the building, preliminary monitoring plan. The crosswork performed in task T6.1 and T2.4 allowed to draw such energy baseline for the 8 SunHorizon demo cases. It was required to design and size the components of TP1-4, including the control, prior the detailed engineering in the T6.2 next phase of the demonstration. The conclusion shows an overview of the key aspects of the 8 demo cases from T2.4 building energy baseline simulation work. It emphasizes that the demo case groups working in parallel had to consider very different integration constraints (single family to multi-apartment buildings or type of building's use like swimming pool, sport center, civic center, or variations in envelope's renovation level, or variations in availability of the monitoring data details). Some demo cases show already good energy efficiency performance level for the envelope (range 32-250 kWh/m² in space heating) or the primary energy consumed by the existing heating / cooling system (range 100-495 kWh/m² as whole non-renewable primary energy demand) or both while others shows poor ones. The report highlights also different system boundaries when including the specific electricity consumption of the whole building for the evaluation of the TP2 and TP4 with PV electricity production or only the electricity consumed by the DHW / heating / cooling system for the evaluation of the TP1 and TP3 with renewable solar thermal production.
