Commercial energy audits in Houston.
We run commercial energy audits for Houston facilities. We review HVAC, lighting, envelope, and equipment operation, then rank the measures worth funding first.
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 we scope an ASHRAE audit level for a Houston facility
A commercial energy audit is a study of how your Houston building uses energy, and it ends with a ranked list of measures worth funding. We look at HVAC systems, lighting, the building envelope, and how equipment is run. We combine a visual inspection, equipment testing, and a review of your past energy data. We add thermal imaging when it helps explain what we find. Houston sits in an energy-intensive climate, so cooling and HVAC control drive much of the bill. Many of the best savings are no-cost or low-cost control changes, and weak audits miss them. We follow ASHRAE audit levels, so you know how deep the study goes and what the report will support.
Pick the audit level before you set the budget
Most Houston facilities have a limited budget for energy work. That budget should go to the best measures, not the easiest ones to sell. Poorly done audits miss no-cost and low-cost items, and many of those are tied to HVAC control. In a climate that runs cooling hard, missing them is expensive. So we match the level to the decision you are making. A Level 1 walk-through finds quick adjustments to equipment. A Level 2 study goes deeper into systems and analysis. A Level 3 audit is investment-grade and targets a few measures with high capital cost.
Audit level choice
How to choose a commercial energy audit level for your Houston building
- Level 1 walk-through: buy this when you want simple, no-cost adjustments found across a Houston site.
- Level 2: buy this when you need a systematic look at HVAC, lighting, envelope, and equipment before you build a budget.
- Level 3 investment-grade: buy this when one measure carries a high capital cost and needs a feasibility case first.
- Level 3 is guided by what Level 1 and Level 2 found, so it is not the right first step on a building with no audit history.
- ASHRAE Standard 211 sets consistent practice for running and reporting commercial audits. Ask every bidder which level they are quoting.


PROJECT PLANNING
Energy audit mistakes that cost Houston facilities money
Funding the wrong measures
BUDGET
Most facilities have a limited budget for efficiency work. Spending it on weak measures means the best ones never get funded.
Overstated savings
ACCURACY
A poor audit can lead you to expect far more than a measure delivers. We tie each recommendation to what we tested and reviewed on your site.
Missed no-cost items
CONTROLS
No-cost and low-cost measures are often tied to HVAC control. Inexperienced auditors miss them, so the waste keeps running month after month.
No level named in the bid
SCOPE
If a proposal never names an ASHRAE level, you cannot compare bids. We state the level and what the report will contain before we start.
WHAT WE HANDLE
Everything under the energy door.
MANAGEMENT
Pre-audit data
What we review before a Houston commercial energy audit
Utility billing history
DATA
We ask for your past electric and gas billing data. Historical energy data analysis is part of the audit, and without it we are guessing at where the load sits.
Equipment list and operation
EQUIPMENT
We record HVAC units, lighting, and major equipment, then note how each one is actually run. Control settings often matter more than the hardware itself.
Building envelope
ENVELOPE
We inspect the envelope during the site walk. In a warm, humid Houston climate, envelope problems and cooling cost show up together.
Past audits and installed work
HISTORY
If a site already had an audit and the measures were installed, it may already be efficient and the remaining savings smaller. Long-running sites with no audit usually have more to find.

BEFORE YOU BUY
What our Houston commercial energy audit report gives you
- An energy profile of the building built from the site walk, equipment testing, and your energy data.
- A ranked list of energy conservation measures, with no-cost and low-cost items called out first.
- Energy use intensity for the building, so you can compare it against your other Houston sites.
- Notes on which measures need a permit path, checked against City of Houston permitting and inspection requirements before a retrofit is scoped.
- A written scope you can hand to bidders, so every price you get covers the same work.
ASKED IN HOUSTON
Common questions about commercial energy audits in Houston
How much does a commercial energy audit cost?
COST
Cost tracks building size, complexity, and audit level. Typical commercial ranges run about $0.08 to $0.24 per square foot. We price your Houston site after we see its size and systems.
What are the three types of energy audits?
LEVELS
ASHRAE Level 1, Level 2, and Level 3. Level 1 is a walk-through, Level 2 is a systematic study, and Level 3 is investment-grade for a few high-capital measures.
Can I do my own energy audit?
IN-HOUSE
Your team can track bills and fix obvious waste. A formal audit needs equipment testing and trained analysis, and inexperienced audits often miss HVAC control savings.
Project in Houston?
Tell us the building, exact scope, and target date. Flux will review the request and send the next step.
QUESTIONS
Straight answers.
Can you audit an occupied Houston building without shutting it down?
Yes. The audit is visual inspection, equipment testing, and data review. We schedule the testing around your operating hours so tenants and production keep running.
What gets the most attention in a Houston energy audit?
Cooling and HVAC control. Houston is an energy-intensive climate, so how the HVAC system is operated usually drives the largest share of the bill.
Which ASHRAE level should our Houston site buy first?
Start with Level 1 if the building has never been audited. Move to Level 2 when you need to budget. Use Level 3 when one high-cost measure needs an investment-grade case.
Is another audit worth it if we already did one?
If the earlier measures were installed, the building may already be efficient and the remaining savings smaller. If it has run for years with no audit, there is usually more to find.
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.
