Testing sites

Syslab Experimental Facility

Site operator:


Site location:

Roskilde, Denmark

SYSLAB is an experimental facility at DTU Risø campus, designed as a testbed for advanced control and communication concepts for power grids. The facility has been extended several times since its inception in 2005.

Today SYSLAB has different kinds of distributed energy technologies, an electricity distribution network and a fully automated control and data acquisition platform functioning within a one square kilometre campus area. An integrated district heating network will be fully functioning in SYSLAB by 2021.

The Flexhouses are three highly automated buildings which are integrated into SYSLAB and used to support relevant R&D activities. In ComBioTES, Flexhouse III will be used to test the developed solutions of EMS algorithm, hardware, and their integration. The 150m2 three-storey house (i.e., two-storey and one basement) has a water-borne central heating system which is fed from the SYSLAB district heating switchboard. The building is fully equipped with a multitude of sensors, including room temperature, light intensity, presence/motion, window, and door contacts, together with a variety of controllable energy consumers’ appliances for space heating and cooling and hot tap water. A custom-made building automation platform allows the deployment of building controllers written in Java or Python which are able to interact with the building as well as process remote control signals from SYSLAB, e.g., for demand response applications.

G3 R&D Building

Site operator:


Site location:

Grenoble, France

The G3 R&D building at CEA Grenoble is in final commissioning and will host R&D activities and a team of around 20/25 people working in it. It has been designed to test innovative solutions in the field of low carbon energy, specifically hydrogen solution and storage of renewable energy linked to heating and cooling technologies.

The building is a mix between a technical hall and offices, as it will host R&D installations, a showroom of some selected technologies and components and offices for researchers on permanent position (about 20-25 people). The building will include several testing cells dedicated to innovative solutions in the field of:

  • Solar heat with a 1000 m² rooftop in metallic duckboard able to host a solar thermal plant. The site presents an annual DNI around 1400 kWh/m²
  • Optimisation of heating and cooling with District Heating networks (the building hosts a DHN substation from Grenoble network that is the second biggest French network)
  • Heat exchanger technologies for district heating
  • Cooling technologies like absorption machines
  • Power to heat and Heat to Power systems
  • Heat Storage

The innovative idea of this building is to connect the new technologies under test to the heating and cooling network of the building and to the fluid loops that are mutualized between the different demonstrations (cooling and heating power of the building are around 500kW). Moreover, for more representativeness, the heating and cooling networks of the building are linked with a real substation of the DHN of Grenoble.

The construction of this building named “Stock ENR” (meaning “Renewable Energy Storage”) has been financed by the French AURA region with funds from the French CPER program.

The total surface of the building is 1800 m², it is composed of six testing cells which size can be adapted to host the projects (cell size of 5*9 m² is planned). A common circulation corridor connected to the cells with glass windows is dedicated to visits. It will allow CEA to demonstrate and disseminate the technologies while doing tests in a confidential area within the cells. One additional cell of the building is also designed as a “show room” of technologies developed by CEA or by partners of CEA.

The COMBIOTES system including the storages coupled to the heat pump will be installed in a specific cell dedicated to heat storage technologies and may be connected to the G3 building networks. The G3 building networks are obviously oversized compared to the specifications of the COMBIOTES storage (3kW/3h are given in the call), which allows operation of the COMBIOTES components in highly representative environment at TRL 6 without potential significant perturbation of the operation of the G3 building.

Family House

Site operator:


Site location:

Bączal Dolny, Poland

The proposed testing site is a single-family house (5 inhabitants) of 200 m2 surface. It is new building, commissioned in 2018. Construction material for walls is cellular concrete (YTONG) isolated by styroprene and for roof steel tile isolated by wood wool. Current source of heat is floor heating based on natural gas. For hot water preparation natural gas, with a 270l hot water boiler supported by air-to-air heat pump. The house is equipped in rooftop PV panels (11x285W), grid connected and operating since 2018.

Office Building

Site operator:

Henan Heating

Site location:

Henan, China

The building that will be used as the testing site is situated in the city of Henan. It is a one-stock office building from 25 people. The building is 20 years old and covers the area of 240 m2. The heating of the building is secured by gas heater. In coming months, heating system will be improved through installation of solar thermal technology.
