Madrid (Spain)

Demo responsible: Empresa Municipal de la Vivienda y Suelo de Madrid SA (EMVS) and Veolia (VEO)

Type of building: Large residential Social housing apartment block, envelope under retrofit, 10 flats with a ground floor + 4 floors (1072 m2) near the town center of Madrid. Solar energy potential: 62 m2. Existing individual appliances per flat: gas boiler supply DHW and space heating through radiator circuit and air/air split for cooling. Yearly thermal demand estimation after envelope retrofit: 13 MWh DHW, 18 MWh electricity, 60 MWh space heating, 4 MWh cooling

Demonstration action:

  • TP4, Parallel integration: reversible HP (BDR) for space heating + cooling + DHW; Thermal output from solar hybrid PV-T (DUALSUN) to cover heat demand and to assist boostHEAT evaporator; PV-T (DUALSUN) electricity production to cover building appliances electricity consumption. HP boiler Adsorption chiller Reversible HP Solar thermal PV Thermal E. Storage RES installed14 — 3×27 kW 35.3 kW 10.5 kW 300 l 94.5 kW
  • Installation of solar panels and HPs’ outdoor fan coil units on the flat roof and connections to technical room
  • Installation of HPs’ indoor unit and tank either in a box on the roof or technical room on ground floor.
  • Redesign centralized space heating, cooling and DHW distribution system for 10 flats
  • Integrated control system for the smart operation of H&C and electrical systems
  • Improved performance on space heating and DHW through heat supply by solar hybrid PV-T (DUALSUN) and thermal energy storage (RATIOTHERM) and reversible heat pump (BDR)
  • Improved self-consumption of electricity from solar hybrid PV-T (DUALSUN) by the reversible electric heat pump in heating and cooling season (BDR) and specific electricity demand of the building

Replicability potential:

  • Large residential and tertiary. New and renovated buildings.
  • Sunny climates

Technical risks:

  • Very limited risk in coupling both innovations (i.e. reversible HP and solar hybrid PV-T).
