Cut rack energy, not food quality.
We optimize your stores so you can focus on selling product.
Technician-led, supermarket-focused energy management — not generic facilities consulting.
MarketZero helps supermarkets lower energy spend, protect product quality, reduce shrink, and keep case and walk-in temperatures in the health department’s comfort zone — while reducing unnecessary contractor invoices and staying ahead of EPA/CARB refrigeration rules.
Serving: Supermarkets, multi-site grocery, cold storage, and convenience stores that want lower bills, better product integrity, and fewer headaches from regulators.
Three pillars to keep your stores efficient, predictable, and compliant.
MarketZero plugs into your existing refrigeration, EMS, and contractor network to drive measurable savings and reduce risk — without adding work to store or facilities teams.
Energy Management
Optimize existing equipment first, then prioritize upgrades where the ROI and rebates make sense.
- Floating suction, floating head, defrost, and case temperature optimization.
- Recommendations on doors, efficient cases, subcoolers, and heat reclaim.
- Utility rebate navigation to lower upfront costs.
- Protecting product quality while reducing shrink and energy use.
Contractor Management
Keep service partners honest, scopes tight, and spend aligned with uptime and food safety.
- Scope, quote, and invoice review before approval.
- Verification that repairs solve root causes — not symptoms.
- Identify pattern failures and “parts-changer” behavior.
- Free your team to focus on store operations.
Compliance Management
Close the loop on leak checks, timelines, and paperwork so you avoid fines and audits.
- Tracking leak inspections, repairs, and retests store-by-store.
- Ensuring complete EPA/CARB documentation after repairs.
- Monitoring leak rates and flagging at-risk stores.
- Alignment with health department temperature standards.
A real store, a real rack, real savings.
This case study highlights how MarketZero optimized a poorly tuned DX rack at a regional supermarket chain — improving product quality, lowering energy spend, and eliminating repeat service issues that were costing the store thousands each year.
The challenge
Temperatures in medium-temp cases were drifting, product complaints were increasing, and energy consumption had risen nearly 18% compared to the same period last year. Contractors were cycling through parts — but not solving the root issues.
- Cases running 3–5°F warmer than setpoint during peak hours.
- High head pressure due to fixed condensing strategy.
- Multiple unnecessary compressor rebuilds quoted.
- EPA leak logs incomplete across the previous 12 months.
What we did
MarketZero performed an on-site/remote hybrid audit, tuned controls, validated contractor work, and implemented a targeted sequence adjustment for the EMS.
- Enabled floating suction based on warmest case cut-in.
- Implemented floating head pressure tied to ambient conditions.
- Corrected defrost schedules and optimized case superheat.
- Audited quotes and denied two non-critical compressor rebuilds.
- Rebuilt EPA/CARB store files and established proper workflows.
How we cut refrigeration energy 10–25% without compromising product quality.
MarketZero specializes in tuning and optimizing the refrigeration strategies that have the biggest impact on rack energy consumption, compressor run hours, case temperatures, and overall store performance. Below are the most common high-ROI strategies we implement for supermarkets.
Floating Suction Optimization
Raise suction pressure whenever the warmest case allows. This reduces compressor lift, cuts run hours, and improves capacity at higher SST.
- Targets setpoint based on warmest evaporator return temp
- Protects product quality while reducing compressor load
- Often delivers the strongest kWh reduction of any EMS strategy
Floating Head Pressure
Modulates head pressure with ambient conditions, lowering compressor discharge pressure whenever outdoor temps permit.
- Reduces compressor amp draw and discharge temps
- Takes advantage of cooler nights and shoulder seasons
- Extends compressor life and reduces oil breakdown
Defrost & Superheat Optimization
Correct defrost scheduling and superheat tuning reduces frost load, improves case performance, and stabilizes case temperatures.
- Prevents over-defrosting and unnecessary heater usage
- Keeps coils efficient and reduces temp swings
- Improves product integrity and reduces shrink
Doors on Open Multi-Deck Cases
One of the highest-ROI capital upgrades. Doors dramatically reduce infiltration load and improve case stability.
- Up to 70% reduction in case infiltration load
- More stable product temps & reduced shrink
- Often utility-rebated for quick ROI
Liquid Subcooling
Subcoolers improve refrigerant quality entering the cases and allow more stable operation at higher suction pressures.
- Improves TEV performance and case stability
- Allows higher suction pressure after optimization
- Reduces compressor runtime and cycling
Compressor Sequencing & VFD Control
Optimize staging so compressors run in the most efficient configuration, and add VFDs where appropriate to reduce cycling and improve part-load efficiency.
- Improves rack stability and reduces cycling
- Protects compressor life and reduces maintenance
- Works extremely well with floating suction/head strategies
Why MarketZero instead of a generic facilities or EMS vendor?
Most “energy programs” stop at dashboards, vague reports, or one-off projects. MarketZero is built by a supermarket refrigeration controls technician who understands how racks actually run day-to-day — and how to turn that into lower bills, fewer callbacks, and fewer compliance headaches.
We plug into your existing racks, EMS, and contractor network and act as your refrigeration and energy management department — without adding headcount. Our only incentive is to reduce your total cost of ownership while protecting product quality and compliance.
- Technician-led: recommendations grounded in real-world service and controls experience.
- Supermarket-focused: no office buildings, no random facilities — just food retail & cold storage.
- Vendor-neutral: we don’t sell equipment, so our guidance isn’t driven by quotas.
- Energy + maintenance + compliance: we look at the full picture, not just kilowatt-hours.
Technician-led, not software-first
Our recommendations are made by someone who has actually commissioned racks, tuned EMS settings, and lived through nuisance alarms — not just read a report.
We sit on your side of the table
We review scopes, quotes, and invoices so you avoid unnecessary rebuilds, oversized projects, and “good for the contractor, bad for the store” decisions.
Energy + product quality + compliance
We don’t chase savings at the expense of food safety. Strategies are validated against case performance, health department expectations, and EPA/CARB rules.
Rebate and project prioritization
We translate utility rebates, case upgrades, VFDs, and doors-on-cases into a clear, ranked roadmap so you know which projects to do first and why.
Ready to see what your stores could be saving?
Book a strategy call and we’ll review one of your racks or locations, talk through current pain points, and outline where energy, maintenance, and compliance opportunities likely sit inside your portfolio.
On a typical 30–45 minute call, we’ll:
- Discuss your current refrigeration, EMS, and contractor setup.
- Review any known problem stores, high-energy sites, or chronic issues.
- Identify quick wins (setpoint tuning, control strategies, oversight) vs. capital projects.
- Outline how MarketZero would plug into your team and existing vendors.
No obligation, no hard sell — just a technician-to-operator conversation about what’s possible in your stores.
