Case Study

Operational Resilience & Circular Design

Galicia, Spain Sector: Food & Beverage (Viticulture)

The Mandate

Develop an integrated sustainability and decarbonization roadmap for a new-build artisanal winery, transitioning from “green intent” to a defensible, site-specific operational strategy.

The Challenge

Wineries are energy-intensive environments where refrigeration, pumping, and waste management are tightly linked to margins. The client required a strategy that reduced long-term grid reliance and resource risk without adding unnecessary operational complexity or “performative” technology.


The Advisory Framework

The engagement resulted in a four-pillar roadmap grounded in the site’s specific climate ($1,300$–$1,400\text{ mm}$ annual rainfall) and the subsoil’s thermal stability ($10$–$16\text{°C}$).

1. Passive Thermal Infrastructure

Rather than relying on energy-intensive chillers to fight external temperature swings, we utilized the site’s natural subsoil stability.

  • Strategy: Semi-underground architecture combined with the high thermal mass of stone and concrete.
  • Outcome: Significant reduction in refrigeration and space-conditioning loads, utilizing the building itself as the primary temperature regulator.

2. Four-Part Energy Decarbonization

Energy was identified as the largest emissions lever under direct control. We moved beyond simple “renewables” to a demand-first hierarchy

  • Passive Reduction: Gravity-assisted product flow to minimize pump runtime.
  • System Optimization: Variable-speed drives and heat pumps to smooth peak loads during harvest.
  • Data Infrastructure: Sub-metering to eliminate “phantom loads” and non-production runtime.
  • Renewable Integration: A solar PV array sized to utilize 50% of the available roof space while providing approximately 75% of the total annual electricity demand.

3. Circular Water Architecture

Leveraging regional rainfall to close the loop on freshwater abstraction.

  • Capture & Storage: Large-scale cistern collection of roof runoff.
  • Nature-Based Treatment: On-site constructed wetlands using gravel beds and microbial processes to treat wastewater.
  • Recovery: Treated water is diverted back to non-potable use (cleaning/irrigation), creating a self-sustaining cycle.

4. Vineyard Waste Valorization

Treating organic by-products as an energy and soil-health asset rather than a disposal cost.

  • Thermal Recovery: Repurposing vine prunings for on-site combustion to provide winery water heating.
  • Nutrient Cycling: Implementing composting and biochar pathways to enhance soil carbon sequestration and long-term vineyard health.

The Commercial Outcome

The final roadmap moved the project from a standard facility design to a low-risk, resource-efficient asset. By treating sustainability as an operational discipline, the winery is projected to operate with $75\%$ less grid-reliance and a closed-loop water system, significantly lowering its long-term OPEX and environmental exposure.
