Mission
The ECOFLEX-project, where nine Belgian partners collaborate, aims to unlock the potential of electric cars and energy communities to balance the grid in a climate neutral way.
Objectives
- Development of intelligent energy management algorithms which can determine optimal setpoints for various controllable assets taking into account the behavioural uncertainty and variety of customer and community requirements
- Determine value propositions which will convince consumers to engage their asset(s) in flexibility services of the energy market
- Investigation of new market models (in contrast to the current central design of/and access rules) for the energy (flexibility) market and definition of the roles of stakeholders
- Demonstration of an user-centered and interoperable ecosystem with a level playing field for companies to enter a profitable supply chain for flexibility services
Green Energy Park
The Vrije Universiteit Brussel (VUB) and the Universitair Ziekenhuis Brussel (UZ Brussel) have set up the non-profit organisation Green Energy Park, with the aim of facilitating research. Among other things, it is developing a large living lab where companies, research institutes and governments work together in co-creation on solutions to societal challenges related to energy and mobility.
The living lab will include a large-scale, innovative electric grid, an ultra-low-temperature heat grid and extensive electric mobility facilities for research purposes. The data centre will valorise its waste heat by connecting it into a strict heating network to serve other buildings on the campus.
smart village lab
In anticipation of Green Energy Park's large-scale living lab, a smaller-scaled living lab has already been built, capable of accommodating initial research needs. This living lab, the Smart Village Lab, Lab consists of a smart distribution cabin, an EV charging plaza, a Control Centre, community batteries and the Smart Home Lab.
The Smart Village Lab was realised by Flux50 and Green Energy Park, through 2 projects: Interreg NWE RegEnergy and ERDF SMEL-1.
Smart home in a smart residential area
The Smart Home Lab consists of 6 ´flexible´ homes that will be used mainly for the development of intelligent systems that allow a home to be controlled smartly and sustainably. The homes will exchange electrical and thermal energy among themselves via a "Smart Energy Grid", an energy network to which collective energy systems such as community batteries and collective charging infrastructure for electric cars are also connected.
Each of the 'flexible homes' includes a typical residential electrical installation with its digital meter, distribution board and PV system. These can also be extended with home energy management systems, home batteries and charging stations.
In terms of electrical consumers, there is a combination of real devices and simulated devices. The simulated appliances are 'controllable consumers', consumers that can play back the real (pre-measured) load profile of the appliance (via controllable dimmers), so that the power profile on the electrical board closely resembles that of a home with real appliances.
Research, development, training and demonstration
For example, you can link solar panels to the car or a home battery, to washing machines or to heating. With the advent of a capacity tariff and the opportunity of maximum self-consumption, it will become important to spread electricity use (peak monitoring) or steer in function of the sun. Smart control is then a possible solution.
Testing such steering is an example of a project that can make use of the lab infrastructure.
The Smart Home Lab can be used for innovation, testing, demonstration as well as training.
The living lab supports Flemish and European research and development projects. Within these projects, new technologies can immediately be tested and further refined in a real environment, which greatly enhances the quality of these projects. Companies that want to test or demonstrate an integration with (community) batteries are also welcome. The living lab is also used for education and training and can be visited by schools and the general public. Thus, everyone can get acquainted with these innovations and their importance in the societal energy transition.

Negundo district
The NEGUNDO district is located at the back of the TOURNAI-WEST I economic activity park, along the highway. The district currently has business, training and innovation centers as well as relay halls and a kindergarden. The site is also equiped with its own set of energy infrastructure.
As owner of the site, IDETA (the Regional Development Agency of Piccardy Wallonia) has included the site in the e-Cloud (2019-2020) and HospiGREEN (2020-2023) energy-related pilot projects. These projects shared locally produced solar and wind energy collectively within the projects' renewable energy communities. The site is therefore experienced in collective self-consumption of renewable electricity.
