Atenea BAS · Houston, Texas · Owner-built, owner-proven

An integrated building automation system
we built for our own buildings.
Zero licensing. Verified savings.

Atenea is BOT's in-house building automation system: the control fabric that executes schedules, setpoints, staggered starts and demand limits across HVAC and lighting — developed and proven on BOT's own buildings before being offered to others. Every control action it takes is scored by continuous M&V, every 15 minutes.

Sec. 01 · Why we built our own

Most landlords rent their
control system. We own ours.

Commercial buildings burn roughly 40% of U.S. electricity, and the machine that decides when every fan, pump and rooftop unit runs is usually a licensed black box. Other landlords pay $50–200K per year in BAS licensing fees for the privilege. We refused to.

BOT is an owner-operator: 4 buildings, roughly 421,000 square feet of Houston commercial real estate, run with below-CPI operating expenses for 19+ consecutive years. When you pay your own utility bills for two decades, recurring licensing stops looking like a norm and starts looking like a leak. So we built Atenea in-house, on edge microcontrollers, for under $50 per controller — with zero licensing fees, ever.

Owning the stack changes the incentives. A vendor's BAS is finished when it's commissioned; ours is finished when the utility bill proves it worked. Atenea was designed as the control arm of a measurement loop, never as a standalone product — if a schedule change doesn't show up as a verified reduction against the baseline, we treat it as a bug. Our writeup on what an integrated building automation system actually integrates goes deeper on this design philosophy.

Sec. 02 · The control fabric

What Atenea actually controls

Integration means one system holding the schedule, the setpoint, the demand strategy and the evidence. Atenea's job is deliberately unglamorous: enforce the operating plan at the equipment, then hand the telemetry to the M&V record.

Two principles govern the strategy. First, schedule-first conservation — you can't get more efficient than off. Second, ASHRAE-style trim-and-respond resets on static pressure and supply-air temperature, so equipment serves the zones that need it instead of the worst-case zone that might. And a human stays in the loop: Atenea executes an operating plan under engineering oversight — it is not an unsupervised autopilot. For what these measures do to a rooftop-unit fleet, see our guide to HVAC optimization for commercial buildings.

Sec. 03 · The honest comparison

Licensed BAS vs. owner-built,
M&V-verified BAS

The differences that matter are not on the feature sheet. They are in the recurring costs and in who has to prove the savings.

DimensionConventional licensed BASAtenea BAS (BOT)
Software licensingTypically $50–200K per year for a commercial landlord, forever.Zero. Owner-built; no recurring license.

Licensing and M&V study figures are typical industry ranges; your quotes will vary by vendor and building. The structural point doesn't: a licensed BAS bills you annually and verifies rarely — ours bills you never and verifies continuously.

Sec. 04 · Skin in the game

Proven on our own buildings first

Every number below comes from a building we own or a client we serve — verified against a baseline, not estimated from a model brochure.

800 Wilcrest, our flagship, cut annual energy use roughly 50% between 2015 and 2025 (time-normalized, not weather-normalized) — and then dropped a further ~25% year-over-year after our own BAS beta went in around March 2025. 11104 West Airport moved all 27 rooftop units from set-and-forget thermostats to enforced operating windows and achieved a ~36% annual electricity reduction from 2018 to 2025, alongside a gas-heat RTU replacement. 11200 Richmond, acquired in September 2025, is already showing a 22.4% verified energy reduction year-to-date — roughly eight months after takeover.

Demand tells the same story: at one building, peak demand fell 36%, from 372 kW to 239 kW — the kind of result that rewires both the distribution charge and the ERCOT 4CP transmission allocation. On the carbon side, a single building shows 135,841 kg of CO2 avoided, IPMVP-grade. And the platform scales beyond our own walls: RMS, the measurement suite Atenea reports into, serves ~600 K-12 schools plus Harris County, with 15 buildings and 44 validated M&V reports. One school saved $13,140 per year with zero capital spent.

Sec. 05 · The yardstick

A BAS without M&V is a promise.
Ours ships with the proof.

This is the part most automation vendors skip, because it can embarrass them. We built it in on purpose.

Most measurement and verification in this industry is a $10–25K engineering study performed once a year — a snapshot, delivered months after the drift it might have caught. BOT's M&V runs automatically every 15 minutes: continuous AI M&V under IPMVP Option C, against weather-normalized baselines with R² above 0.96. Every schedule Atenea enforces, every staggered start, every setback shows up as a gap between expected and actual load — or it doesn't, and we find out the same day.

Controls are verified by continuous M&V rather than assumed. That sentence is the whole product philosophy, and it's why the BAS and the measurement platform were built as one loop instead of two purchases. Evaluating the software side?

Sec. 06 · Questions we actually get

Integrated BAS — FAQ

What is an integrated building automation system?
A BAS that controls HVAC and lighting from one platform — schedules, setpoints, setbacks, demand strategies — and ties every control action to measurement. Every action Atenea takes feeds RMS, so each decision's energy result is visible in a continuous IPMVP Option C M&V record at 15-minute resolution.
How much does a commercial building automation system cost?
Conventional platforms typically carry recurring licensing of roughly $50–200K per year for a commercial landlord, on top of hardware and integration. BOT built Atenea in-house on edge microcontrollers for under $50 per controller, with zero licensing fees.
How do you prove a BAS actually saves energy?
Measurement and verification. The industry norm is a $10–25K once-a-year study. Ours runs automatically every 15 minutes — IPMVP Option C, baselines at R² > 0.96 — so savings are scored every interval. Example: a verified 22.4% energy reduction year-to-date at 11200 Richmond, about eight months after we acquired the building.
Can a BAS reduce peak demand charges?
Yes — demand is often the most controllable line on the bill. Staggered morning starts, demand ceilings and pre-cool windows keep equipment off the same 15-minute interval. At one of our buildings, peak demand dropped 36%, from 372 kW to 239 kW. See our explainer on demand charge reduction for the mechanics.
