About the project
The 5 years EU funded project aims to set up a multidisciplinary team in the NZED field which gathers several competences: Urban planning, Energy demand in buildings, Heat and cold production and storage, Electricity production and distribution, Control strategies. To cover all these disciplines, five departments from the UMONS Research Institute for Energy are involved:
- URBAINE (Research Center of the Faculty of Architecture and Urban Planning)
- Thermal Engineering and Combustion Department (Faculty of Engineering)
- Thermodynamics Department (Faculty of Engineering)
- Electrical Engineering Department (Faculty of Engineering)
- Automatic and Control Department (Faculty of Engineering)
The scientific Team is expected to develop and implement the appropriate R&D&I program to develop and validate knowledge, ready-to-use tools and methodologies that make possible the future development of Net Zero Energy Districts meaning that heat and electricity consumed by the fixed appliances (mainly buildings) are balanced by a local production based on renewable energies. This net zero energy balance should be reached by promoting use of energy produced locally (inside the city area) rather than massive energy exchanges through the city district boundaries which means that the will is to evolve towards the concept of Zero Energy City Districts. Reaching a high level of energy autarky (100% for heat demand with a green contribution of 90%, more than 50% of green electricity produced and used locally) is therefore a major objective. The city districts of interest are new suburban areas.
Thus, the R&D objectives of the RESIZED Project are:
- For electricity, the city district to be equipped with a micro-grid to ensure the best and most of the local use of green electricity produced by the city district itself; the micro-grid will be connected to the global grid (or otherwise main grid) and energy transfer will be allowed as a way to guarantee the grid stability; the micro-grid and the local production system should ensure that 50% of the needs can be covered by the local and green electricity production without any transfer from the global grids.
- For heat, the city district to be equipped with a centralized heat storage system (medium- and long term storages) connected to solar collectors and to a heat distribution system (inside the city district); the back-up heat production will be a heat pump. 90% of the needs should be covered by local green production.
- For the built environment – buildings to be low energy (heat demand for space heating <50 kWh /(m2 year)) or passive buildings (heat demand for space heating < 15 kWh /(m2 year)) designed in such a way that (i) their envelope ensures electricity and heat production, (ii) their heat load profile facilitates the operation of the centralized heat storage, (iii) their cooling load profile does not require any active cooling.
