MEP delivers ASHRAE-style, ISO 50001-compatible energy audits for industrial and commercial sites in Mexico. No equipment sales, no vendor affiliations, no commission on what you buy. The audit is the product, built on measured data and documented to hold up in front of your CFO, your procurement committee, and an external auditor.
The first step is not a site visit. It is a short conversation about the plant and the decision in front of you. NDA offered up front.Audit experience across industrial and commercial operations
An audit is only worth having when the firm doing it has no stake in the answer.
The firm running them sells solar, capacitor banks, chillers, or a service contract, and the report tends to recommend exactly that. You repay the free walkthrough later, in the equipment you were steered toward.
The walkthrough is free because the answer was decided before anyone looked at the bills. If the fix at your site is a load-schedule change and compressed-air repairs, MEP says so, because there is nothing else it is trying to sell.
Where capital is genuinely warranted, you get a vendor-neutral specification and an honest bid evaluation on identical terms, not a nudge toward one brand.
Four tests every finding has to pass before it reaches your CFO, your procurement committee, or an external auditor.
Built from your real electricity, demand, gas, load-factor, and power-factor history rather than a single month or a rule of thumb.
Consumption allocated across HVAC, compressed air, chilled water, lighting, process loads, cooling towers, and support areas, with a focused measurement campaign where the data does not already exist.
Each energy conservation measure comes with a defined scope, an investment estimate, quantified savings, an annual peso impact, a payback, and an avoided-CO2 figure.
Methodology maps to ASHRAE 211, EN 16247, ISO 50002, and ISO 50001, with savings verification aligned to IPMVP and ISO 50015. A full Level 2 report commonly runs past 300 pages, because that is what it takes to make each number defensible.
Systems covered
Not every system is in scope on every engagement. The audit level and the decision in front of you set the boundary.

Figures shown are for one facility with its own baseline and tariff. Identified savings, not verified under M&V. MEP does not guarantee savings.
The full report runs past 300 pages. A redacted sample is available under NDA, so your finance and engineering teams can judge the depth before any commitment.
Request a redacted sample reportIdentified savings and savings verified under M&V are kept separate throughout, so finance books only what has been proven.
What can we defensibly book, and what is only identified?
Measure-level investment, savings, payback, and CO2, with sources traced
Can this be done without risking production, quality, or reliability?
Measurement plan, operating constraints, implementation window
Can vendors bid the same scope on identical terms?
Vendor-neutral specification and normalized bid evaluation
Does this support our energy management and disclosure obligations?
Baselines, Energy Performance Indicators, and ISO 50001-compatible reporting
Representative schedule
An ASHRAE Level 2 audit at an industrial manufacturing facility in Mexico, from first data request to presentation of results. Stages overlap by design: processing begins while recorders are still in the field.
| No. | Stage | Principal activities | Start | End | Days | AugSepOctNovDec |

In a completed ASHRAE-style audit of a manufacturing facility in San Luis Potosí, roughly MXN $8.4 million in annual savings was identified across five categories of energy conservation measures, with the audit fee recovered within the first billing cycle after implementation began.
That is one facility with its own baseline, and these are identified savings rather than savings verified under M&V. Identified savings across audited sites have historically ranged from around 10 percent to more than 50 percent, depending largely on plant age and operating condition. The only way to know where your site lands is to measure it. MEP does not guarantee savings.
A no-obligation assessment of where savings and any tariff or power-factor exposure likely sit at your plant. You do not need the heaviest tool to start. Match the audit to the decision in front of you.
Request a scope recommendationOrganizations remain confidential. Verification contacts are available during qualified evaluation.
The energy audit recommendations were practical and supported by solid financial and operational rationale, making them easy to evaluate and act upon.
The energy study was very well done and delivered real results. The team took the time to understand how our plant actually operates and provided clear, practical recommendations.
The support we received on our Power Purchase Agreement was excellent. The team conducted a detailed and professional review.
Feedback from completed engagements. Client identities remain confidential. Individual results depend on facility profile, tariff, contract terms, and execution.
The first step is not a site visit. It is a short conversation, so you see a credible first assessment before you commit to anything. Request the assessment and MEP will show you where you stand. NDA signed first.
