Green AC&DC Energy™ – Retail & Food Chains
Hybrid AC&DC efficiency for cold chains

Retail & Food Chains – cold cabinets, freezers & Smart Micro-Door™ retrofit

The Green AC&DC Energy™ retail module focuses on the most expensive part of your electricity bill – the cold chain. Vertical cabinets, island freezers, walk-in rooms and back-of-house refrigeration are optimised and upgraded, including Smart Micro-Door System™ retrofits for open cabinets. The result: less kWh per store, more comfort for customers and a transparent ΔE* model for ESCOs and investors.

Key benefits of the Green AC&DC Energy™ retail pilot

A retail pilot is not only about replacing cabinets. It is about how the entire cold chain behaves – from open cabinets with Smart Micro-Door System™ to back-of-house coolers and night covers – with clear kWh, € and CO₂ indicators per store and per m².

Cold chain

Lower kWh per cabinet and per metre

Vertical cabinets, island freezers and walk-in rooms are mapped and optimised. Inefficient units are replaced or upgraded, and operating parameters are aligned with real opening hours and product needs.

Typical result: fewer compressors working at night, less defrost waste and lower peak loads on hot days.
Smart Micro-Door

Retrofit for open cabinets – without changing the whole line

Where architecture or sales logic require open cabinets, Smart Micro-Door System™ can be used as a retrofit. It reduces cold spillage into the aisle and stabilises cabinet temperature with minimal impact on visibility and access.

Pilot stores become reference points for rolling out Micro-Door solutions across multiple locations.
Customers & CO₂

Better comfort, product quality and emissions

Warmer aisles, fewer “cold corridors”, more stable product temperatures and lower electricity bills – all tied together through ΔE* monitoring for ESCO partners, banks and your board.

ΔE* shows “before vs after” per store, per cabinet group and per m² sales area.
How the retail pilot is structured

From one model store to a chain-wide plan

The retail module starts with one or a small cluster of model stores. ΔE* is used to document the effect and build a bankable, ESCO-ready plan for replication across the chain.

1

Inventory & baseline

All cabinets, freezers and cold rooms are mapped: type, age, refrigerant, technical data and typical loading. Existing invoices and sub-metering (where available) are translated into a ΔE* baseline.

2

Scenario & Smart Micro-Door

Together with the chain and ESCO we define which units are replaced, which are retrofitted with Smart Micro-Door System™ and where operating regimes are adjusted. Only solutions consistent with Green AC&DC Energy™ logic are used.

3

Monitoring & rollout plan

After implementation we track ΔE* per store. The pilot becomes a template for the rest of the portfolio – including a technical and financial roadmap for ESCO contracts or your own CAPEX.

Are you responsible for a retail or food chain portfolio? Use one or a few model stores to test the full Green AC&DC Energy™ retail concept – from open cabinets with Smart Micro-Door System™ to back-of-house cold rooms. The result is a measurable pilot with clear ΔE* and a narrative for management and investors.
