BIGG Project Greek pilot: Business and use cases
The project BIGG (Building Information aGGregation, harmonization and analytics platform) launched in December 2020, demonstrates the application of big data technologies and data analytic techniques in the complete buildings life-cycle, in more than 4000 buildings in 6 large-scale pilots, 3 in Spain (Catalonia) and 3 in Greece.
BIGG is firmly grounded in reality and will start from a set of 6 high-level business cases, spanning a broad range of use cases as well as distinct international settings. A bottom-up business-case based methodology will be followed to define a widely applicable reference architecture. Each of the cases will be demonstrated in its own real-life pilots, building on the common architecture and toolbox.
The following picture represents a high-level view of the 6 business cases considered in BIGG pilots.
The first newsletter discussed the business cases supported by the Catalan pilots, which were focused on the needs of the public administrations to enhance the data gathering and analysis for monitoring the performance and improving the energy efficiency of the building stock.
This second newsletter focuses on the business cases supported by the Greek pilots.
BIGG Greek Pilots Business Cases
The Greek pilots are divided into Business Cases 4&5 and Business Case 6. The first ones focus on 17 large commercial office buildings in Athens managed through Energy Performance Contracting (EPC) and Maintenance Contract. The pilot site will demonstrate the application of EPC-based management for commercial buildings, whose main objective will be continuously optimizing the building operation consumption, to guarantee the comfort of occupants, by controlling HVAC systems/lighting. The pilot scenario for Business Case 6 will focus on delivering flexibility services by managing appliances of residential and commercial consumers of electricity and natural gas, spread across various cities of Greece (Athens, Thessaloniki, Volos and others).
Business Case 4:
Energy Performance Contract-based savings in commercial buildings
The objective of this Business Case 4 (BC4) is to create a solution for a comprehensive management of EPC contracts. This solution will have to enable smooth communication between the Energy Service Company (ESCO), managing the EPC, and the customer who has to be notified in case of any major savings deviation or corrective actions required.
This BC4 will consist mainly on the control of different systems of customer buildings, as HVAC or lighting in order to improve its energy efficiency. Different steps include the definition of KPIs, KPIs monitoring and KPIs related data collection.
This business case consists in 3 use cases:
Use cases for Business 4:
Business Case 5:
Buildings for occupants – Comfort case
The idea is to optimize comfort in buildings, using Building Management Systems (BMS) and based on the outside weather, a programed occupancy schedule and forecast of energy prices.

Business Case 6:
Flexibility potential of residential consumers on electricity and natural gas
This BC will demonstrate and exploit the flexibility potential of residential and commercial buildings in electricity and natural gas.
The focus will be on characterizing the availability and distribution of flexible loads in the buildings by analyzing a plurality of data captured from heterogeneous sources: devices deployed at consumer premises (smart meters, heating controllers, Internet of Things – IoT sensors, etc.), user preferences (comfort limits, schedules, etc.) collected through smartphone applications, external services (weather forecast, balancing market prices, consumption & billing) and static information, such as the building characteristics, as captured by the building EPC.
