Pasaia (Spain)
Pasaia (Spain)
The Spanish pilot project will take place in Pasaia in the region of Guipuzkoa. The building contains eight dwellings homes owned by a public social housing. The climate is typical of the Cantabrian coast, with cold winters and mild summers.
Climatic zone (Köppen): Climatic zone (Köppen): Cfb (temperate oceanic climate)
Weather characteristics:
- Mild winter, with average temperature clearly higher than the other pilot sites
- Summer: temperatures remain also moderate
Building description
Built in 2008, multi-family building with 8 dwellings, split into two floors. All the dwellings are similar in size: 2 or 3 room apartments, ≈75 m2/each.
Ownership: Building owned by a public non-profit social housing company
Existing heating and DHW System: Individual gas boilers for space heating and DHW and a solar thermal installation (never started) in the roof with individual thermal storage in each dwelling (100 litres). Radiators as heat emitters in the main rooms. Supply/return temperatures: 80/60 ºC.
Existing control and monitoring System: There is no monitoring system installed. Basic control system in each dwelling: water supply controlled by ambient thermostats (on/off control strategy).
Building energy consumption
Consumption data (estimations based on “Plan Zero Plana”):
Space heating and DHW ≈ 32,3 MWh/y
Electricity consumption ≈ 12,8 MWh/y
This pilot has now successfully entered the operation and monitoring phase
Since October 2023, the newly installed HAPPENING system at Pasaia has been running efficiently, with continuous control adjustments and improvements enhancing its performance.
Installation process
Preliminary results
Even though the monitoring of photovoltaics (PV) has not started yet, preliminary results indicate substantial energy savings, with significant reductions in primary energy (PE) consumption compared to traditional natural gas boilers.
