NREL — Hybrid DER Systems Report
Our microgrid architecture is based on NREL’s finding that hybrid systems (PV + battery + generator) consistently outperform single-source designs in both reliability and lifecycle cost. This is why VEVA uses a 5-layer energy stack, not just solar.

NREL — Neighborhood-Scale Microgrids
Validates our cluster approach: 10–20 homes sharing distributed energy resources is the optimal scale for microgrid resilience. Directly informs VEVA settlement sizing.

US EPA — Green Power Equivalency Calculator
Source for our EV energy math: 36.7 kWh/100 miles (≈22.8 kWh/100 km). Used to calculate per-home EV charging demand and size the smart charging pool.

IEA-PVPS — Spain National Survey 2023
Our solar yield calculations: 1,350–1,450 kWh/kWp/year (fixed-mount) and up to 2,127 kWh/kWp (tracking) for Spanish sites. Basis for all PV array sizing.

NREL — Energy Storage Technology Review
Critical distinction between power capacity (kW) and energy capacity (kWh) for battery sizing. Informs our BESS specification: 500 kWh–2 MWh usable with 2–3 day autonomy target.

INE — Spain in Figures 2025
Official Spanish domestic water consumption: 128 L/person/day. Our target of 90–120 L/person/day is set against this benchmark — economical but not ascetic.

MITECO — Water in Spain
Spain’s national water stress data, irrigation demand patterns, and seasonal variation. Critical for sizing water storage and understanding peak summer agricultural demand (3–5× domestic use).

Garrigues — Spain Water Reuse Regulations
Legal framework for greywater reuse in Spain under Royal Decree 1620/2007 and 2023 updates. Determines what VEVA can legally do with treated wastewater for irrigation.

Nature (2024) — Decentralized Water Systems
Peer-reviewed confirmation that decentralized water/wastewater systems significantly strengthen settlement resilience vs. centralized municipal dependency. Validates our multi-source approach.

MDPI (2023) — Land Footprint & Food Self-Sufficiency
Quantifies how animal-heavy diets dramatically increase land requirements. Basis for VEVA’s plant-forward + eggs + poultry strategy as the land-optimal protein mix.

WHO — WASH (Water, Sanitation, Hygiene)
WHO directly links WASH to disease prevention. Sanitation failure is the #1 historical cause of settlement collapse. This drives our insistence on professional wastewater treatment, not DIY septic.

WHO — Antimicrobial Resistance
All antibiotic use in VEVA follows WHO protocols with diagnostic criteria. Improper use drives resistance — a critical risk for any community with limited pharmaceutical resupply.

WHO — Essential Medicines Lists
Framework for our essential medicines stockpile. The WHO Model List defines the minimum needed for a basic healthcare system — our pharmacy follows this structure with 90-day reserves.

FAO — Community Seed Banks
FAO promotes community seed banks as tools for resilience and preservation of locally adapted varieties. VEVA’s seed bank follows this model with annual viability testing and cross-settlement duplication.

FAO — Sustainable Food Cold Chains
Post-harvest losses from weak cold chains destroy a significant share of production. This is why VEVA cold rooms are priority loads on the energy system — always powered, never shed.

Passive House Institute — Building Certification
Passive House envelope cuts heating/cooling demand by ~80%. Every VEVA home targets this standard — the single biggest leverage point for energy autonomy.
