ABOUT THESE DEMONSTRATION SITES

The systems will be demonstrated at four demo sites: a pilot office building in Seville (Spain, ACCIONA Construction); a water treatment plant in Madrid (Canal de Isabel II & ACCIONA Water); a Pulp and Paper mill in Setubal (Portugal, The Navigator Company); and a student hall in Badajoz (Spain, University of Extremadura).

During the first year of the project, the Demo sites have been evaluated in order to be equipped with their respective LowUP systems during the next year. In parallel, the individual components have been designed and customized for each one of the sites. 

Demo #1: Pilot office in Seville

CONCEPT TO DEMONSTRATE: Heat LowUP, Cool LowUP

TECHNOLOGY CONCERNED: Low temperature radiant floor technology provided by RDZ in combination with hybrid solar thermal collectors by ENDEF, heat recovery system and stratified storage.

CONCEPT OF THE DEMONSTRATION: The goal is to use solar energy to heat an office space, using hybrid thermal-PV solar collectors which also produce electricity for the system, with a heat pump as a back-up system for the moments of solar absence.

EXPECTED RESULTS: The system is expected to achieve thermal indoor comfort with lower temperature respect to actual technology, storing excess of heat efficiently for low solar radiation periods, improving energetic consumption of the system and minimising the architectural impact.

The former warehouse enclosed in Acciona’s Test Centre for Energy Efficiency and Renewable Energy Solutions (CESE3R) has become a retrofitted building that matches the regulatory conditions regarding constructive and mechanical installations.

Demo #2: Student hall in Badajoz (RUCAB)

CONCEPT TO DEMONSTRATE: Heat Low-UP

TECHNOLOGY CONCERNED: Wasenco provides a self-cleaning heat recovery system for waste water with multi-usable Ecowec hybrid heat exchanger.

CONCEPT OF THE DEMONSTRATION: The Ecowec hybrid heat exchanger is installed to RUCAB campus kitchen and it is ready for testing. Ecowec will pre-heat the dishwashers inlet water with the heat of the waste water coming from the kitchen. The target is to recycle the heat energy and lower the electric consumption.

EXPECTED RESULTS: The system is expected to reduce the electric consumption of the existing dishwashers through a preheating of the water, minimising the consumption and impact of the existing boiler.

In collaboration with the University of Badajoz, this is the second LowUP demonstration site. This hall of residence is modern and functional located next to the university campus of Badajoz (Spain). Here, the system to recover heating from the sewage will be installed and tested, as a novelty way to operate in the heating supply system.

Demo #3: Waste Water Treatment Plant in Madrid

CONCEPT TO DEMONSTRATE: HP Low-UP

TECHNOLOGY CONCERNED:  POZZI provides a self-cleaning heat recovery system for sludges out-coming from a bio-digestion tank of the waste water treatment plant, specifically selected for its heat recovery potential.

CONCEPT OF THE DEMONSTRATION: The POZZI system will be installed in life after the bio-digestion tank for waste water treatment sludges, with the goal to recover heat from the biologic anaerobic processes before dismissal.

EXPECTED RESULTS: The system is expected to efficiently recover an important quantity of energy from an effluent with residual energy actually not used in the paper factory. This heat recovered is afterwards re-injected it in the cycle to reduce the global consumption of the plant.

In collaboration with Canal de Isabel II and Acciona Aqua, this is the third LowUP demonstration site. The “Arroyo Culebro Baja WWTP” manages part of the depuration of the residual water that comes from the city of Madrid.

Demo #4: Pulp & Paper mill

CONCEPT TO DEMONSTRATE: HP Low-UP

TECHNOLOGY CONCERNED:  POZZI provides a self-cleaning heat recovery system for effluent coming from the paper and pulp manufacturing process.

CONCEPT OF THE DEMONSTRATION: The POZZI system will be installed close to the pool for primary treatment of the water treatment plant, with the goal to recover heat from the paper manufacturing processes.

EXPECTED RESULTS: The system is expected to recover an important quantity of energy from an affluent with residual energy actually not used, in order to re-inject it in the cycle and reduce the global consumption of the plant.

In collaboration with Navigator, this is LowUP’s fourth demonstration site. The Setúbal Industrial Complex is located on the Mitrena peninsula, near the city of Setúbal,(Portugal). This site is home to a pulp mill and two paper mills, one of which (About the Future) was inaugurated in 2009 and is one of the largest and most sophisticated plants in the world.
