Commercial energy audits in Nashville.
Flux runs commercial energy audits for Nashville buildings, from a walkthrough that finds control fixes to an investment-grade study on the measures you plan to fund.
Find the waste before you buy the upgrade.
Most commercial buildings are paying for energy they never use. A proper commercial energy audit puts numbers on it: where the waste is, what the fix costs, and what it returns. From there, efficiency consultants sequence the upgrades so the cheap wins pay for the big ones.
The audit also tells you when the answer is bigger than efficiency. High demand charges point at battery storage; aging equipment points at a mechanical replacement that pays back in utility savings. Either way, you decide with real numbers on the table.

How Flux audits energy use in Nashville commercial buildings
A commercial energy audit is a full, on-site review of how your Nashville building uses energy, run by a certified energy auditor. We walk the building, read your utility history, and check how HVAC, lighting, controls, and the envelope really run day to day. You get a ranked list of energy conservation measures, not a binder. Nashville is served by Nashville Electric Service, a TVA local power company, so the audit cannot stop at the property line. We mark which measures are worth taking to NES, which ones are no-cost control fixes you can make right away, and which ones need a permit from Metro Codes before a crew starts.
Line your Nashville audit up with NES and TVA EnergyRight
Power in Nashville comes from Nashville Electric Service, a TVA local power company. TVA runs EnergyRight programs, and NES was named a TVA Top Performer across several of those categories, including demand response and PowerFlex participation. That changes how we score your measures. A measure that only cuts kilowatt-hours is judged one way. A measure that also shifts or sheds load during a peak is judged another way, because it can matter twice. We name the measures worth taking to NES, and we ask you to confirm current program terms directly with them before you budget. We do not set those terms.
Audit intake
What we need before a commercial energy audit in Nashville
NES billing history
BASELINE
We pull your NES electric history and read usage against billed demand. If demand drives the bill, control and load-shifting measures rank ahead of a lighting swap. If total use drives it, that order flips.
Nameplates on every unit
EQUIPMENT
We log make, model, and capacity on rooftop units, chillers, boilers, and water heating. A unit near the end of its life gets scoped as a replacement. A healthy unit gets scoped as a controls and tune-up fix.
Control sequences and setpoints
CONTROLS
We read schedules, setpoints, and standing overrides in your building automation system. The no-cost and low-cost wins usually sit in HVAC control, and a thin audit walks right past them.
Prior audit reports
HISTORY
We ask what a past audit recommended and what actually got installed. A building that already did the easy measures has less left to find, and you should know that before you pay for a deep study.
Operating hours by area
SCHEDULE
We map when each area is truly occupied, not what the lease says. Off-hours runtime is what turns a schedule change into a funded measure instead of a suggestion.
PROJECT PLANNING
Permits and code steps after a commercial energy audit in Nashville
Measures that become renovation work
PERMIT
Rooftop unit swaps, envelope work, and electrical changes go through the Metro Nashville Department of Codes and Building Safety commercial permit process. We tag those measures so nobody bids them as a same-visit fix.
Anything you add to the parcel
ZONING
If a measure adds a structure, such as an equipment enclosure or a new building, zoning examiners review use, setback, footprint, and height against your parcel's zoning. That review can change where the equipment is allowed to sit.
Two lanes in the report
SEQUENCE
We split findings into measures we can run now and measures that wait on Metro Codes review. That split keeps your first savings from stalling behind a plan review on a larger project.
Scope written for bidding
BIDS
Each capital measure gets equipment, location, and existing conditions written down, so contractors bid the same job. Vague measures come back as prices for different jobs.
WHAT WE HANDLE
Everything under the energy door.
MANAGEMENT
Buying the audit
How to buy a commercial energy audit in Nashville
- Decide the depth before you ask for a price. A walkthrough finds the easy, no-cost adjustments. An investment-grade audit is built to defend a few specific measures that carry high capital cost.
- Ask how the auditor treats HVAC control. Weak audits skip the no-cost and low-cost control fixes and jump straight to buying equipment.
- Ask what building data each recommended measure came from. A measure with no metering, nameplate, or runtime behind it is a guess, and a wrong measure eats a limited efficiency budget.
- Hand over your past audit and what got built from it, so nobody bills you to find measures that are already installed.
- Ask which measures will need a Metro Codes permit. That answer changes your schedule, your bid package, and when the savings actually start.
BEFORE YOU BUY
What is in your Nashville commercial energy audit report
- A baseline of how the building uses energy, including energy use intensity, so next year can be compared to this one.
- Reporting that follows the ASHRAE practice for conducting and reporting commercial energy audits, so another engineer can check our work.
- A ranked list of energy conservation measures, with no-cost and low-cost control fixes listed apart from capital work.
- A short list of measures that deserve an investment-grade study, which is a targeted look at the feasibility of a few measures with high capital cost.
- Notes on which measures to take to NES and which ones need Metro Codes review before you set a budget.
- Envelope findings kept separate from mechanical findings, so a roof or wall decision is not buried inside an HVAC line item.
ASKED IN NASHVILLE
Common questions about commercial energy audits in Nashville
How much does a commercial energy audit cost?
COST
Cost moves with building size, how complex the systems are, and how deep the audit goes. We scope and price yours after we see the equipment list and floor area.
What are the three types of energy audits?
LEVELS
The industry follows the ASHRAE audit levels. They run from a simple walkthrough that finds no-cost adjustments up to an investment-grade audit built around a few specific high-cost measures.
Can I do my own energy audit?
IN-HOUSE
Your team can spot obvious waste like lights and off-hours runtime. A certified auditor is what you need to defend a capital measure, since a poor audit sends budget to the wrong fix.
Is an energy audit worth the cost?
VALUE
It depends on your history. If past audit measures were installed, the building may already be efficient. If it has run for years with no audit, there is usually real money on the table.

QUESTIONS
Straight answers.
Does Nashville Electric Service change how our energy audit is written?
Yes. NES is a TVA local power company and was named a TVA EnergyRight Top Performer in categories including demand response and PowerFlex. We flag the measures worth taking to NES, then ask you to confirm current terms with them before you budget.
Will measures from a Nashville energy audit need a permit?
Some will. Equipment and building changes run through the Metro Nashville Department of Codes and Building Safety commercial permit process, and anything you add to the parcel also gets a zoning review for use, setback, footprint, and height.
Our Nashville building has never had an energy audit. Does that change what you find?
Usually yes. A building that has run for years with no audit tends to hold more savings than one that already installed the measures from a past audit. That is why we ask for the audit history before we set the scope.
Can you audit our Nashville building while it stays open?
Yes. We walk occupied areas during normal hours and time the mechanical walk for when the building is under real cooling load, so rooftop units and controls are watched while running instead of guessed at.
GET STARTED
Find the waste in your building.
The audit is free to scope, and most audits find their fee several times over. Tell us about the building and we'll price yours.
