How do cities turn stable underground temperatures into reliable, low‑carbon comfort for buildings – year‑round and at scale? In ATELIER, TELUR demonstrates a ground‑source heat pump (GSHP) approach that harnesses the earth’s thermal stability to deliver heating, cooling and domestic hot water with very high efficiency and extremely low CO₂ emissions. In Bilbao’s PED at Zorrotzaurre island, three areas (north, centre and south) are being connected via a low‑temperature geothermal loop to meet local thermal demand and export surplus – forming a backbone for a Positive Energy District. Expect practical insights on design choices (closed/open/hybrid loops), performance, lifecycle considerations, and where GSHPs make the biggest impact in urban redevelopment and retrofit. TELUR will also touch on challenges (upfront investment, perceived complexity) and evolving business models (ESCO delivery, low‑temperature district networks).
Key Takeaways:
- How GSHPs work in PEDs: Why geothermal loops enable efficient heating & cooling independently of outdoor conditions.
- Performance in practice: Typical SPF range (3–5) and a concrete Beta II example where switching from ASHP to GSHP doubled SPF (2.2 → 4.4).
- Urban deployment lessons: Designing closed/open/hybrid loops tailored to hydrogeology, space and building needs; maintenance accessibility.
- Business models & scale‑up: ESCO pathways and extending low‑temperature networks at district level.

About TELUR’s solution
TELUR’s GSHP solution uses ground thermal stability to produce renewable heating, cooling and DHW. It is highly efficient, weather‑independent, compatible with other renewables, and suitable for both new build and refurbishment. Indicative energy savings of ~40–60% have been observed, with long equipment lifetimes (up to ~50 years for ground exchangers, ~20 years for plant room equipment).
