Continuous Building Savings

Your HVAC is leaking
money. Every month.

One gateway plugs into the BMS you already have,
delivering a continuously updated, ROI-ranked audit.

See how much you could save

    No capital outlay. Your team stays in control.

Savings you can capture, ranked by OpEx reduction

A continuous view of where your building wastes energy, cost reductions from each fix, and which improvements deliver the fastest payback.

Fixing these inefficiencies also extends equipment life and eases occupant complaints.

Recover savings with zero capital

Many of the highest-value fixes are setpoint changes you approve with no new equipment or retrofit.

Ranked by annual savings

Every finding is ranked by estimated annual savings, allowing you to prioritize fixes.

Invest only when it's justified

Capital projects are recommended only when the projected savings justify the spend, complete with expected payback.

Build lasting value

Recovered dollars strengthen the long-term value of every building, improving operating performance and increasing asset value.

What you get

Your monthly savings report

See where your building is losing money, which opportunities deserve attention now, and what can wait. Most fixes require no capital. The rest include the information you need to plan ahead.

Every flagged opportunity is backed by raw equipment data. Proof your team can verify, and that utility programs accept for rebates.

WHY R-ZERO

Aligned to your savings,
not our revenue

Most building vendors make money when you buy equipment or book service hours. R-Zero doesn't. Every recommendation is driven by your financial return, not ours.

Independent recommendations

We don't sell the equipment or profit from service calls, so every recommendation is prioritized by the value it delivers only to you.

No upsell conflict

You'll never be pushed toward capital spend. Just impartial recommendations, made only when the savings clearly justify them.

Vendor-neutral

Works alongside your existing BMS, regardless of controls brand.

Portfolio-wide

Analyze your entire portfolio through one neutral lens, with consistent reporting and prioritization across every property.

SECURITY

Built for your IT and OT security review

Outbound-only by design. The gateway clears an enterprise security review with minimal lift.

No ports opened to external sources, minimizing attack surface and simplifying firewall approval. Outbound only, TLS, over standard ports.
R-Zero delivers recommendations. Your team decides what to implement in your controls.
Security controls independently audited and attested.
Recommendations follow standard ASHRAE Guideline 36 sequences and other standards, including ASHRAE 90.1, 62.1, and Guideline 22.

SECURITY

No inbound connections

No ports opened to external sources, minimizing attack surface and simplifying firewall approval. Outbound only, TLS, over standard ports.

Bounded writes

Every write sits below operator priority, is clamped to commissioned limits, auto-releases on loss of communication, and has a manual kill switch.

Fixes only on your approval

The gateway writes a setpoint only after your team approves it.

Walkthrough: a zero-cost fix

Over-conditioning for current occupancy
Rooms are getting far more conditioned air than the people in them need.

Why it's costing you
minimum airflow was tuned for a fuller building. The gap between the air you're delivering and how full the space actually is — that's energy you pay for that nobody uses.

The fix
R-Zero recommends trimming minimum-airflow setpoints to match real-time occupancy, room by room, within safe limits. Immediate. No cost to recover.

Energy is one of the largest controllable line items in a commercial portfolio. R-Zero cuts HVAC energy 20–40%, verified in your utility bills. Because the savings are permanent operating-cost reductions, every dollar flows straight to NOI. At a 5% cap rate, $100K in annual savings adds $2M in asset value.
R-Zero conditions occupied zones precisely instead of running the whole building flat-out, so space feels better and air stays healthier. That matters to the bottom line: a one-point rise in tenant satisfaction tracks to a 23% lower probability of moving out (Hu, Kok & Palacios, 2024), and every renewed lease protects NOI.
Occupancy-driven ventilation means fewer comfort complaints landing on your team, less manual setpoint chasing, and less reactive maintenance. The system runs autonomously across every building, freeing staff from day-to-day HVAC management to focus on higher-value work.
R-Zero deploys as an operating expense. No capital request, no procurement cycle, no line item in the capital plan. It's paid from verified savings, so it funds itself. And as building-performance laws tighten across 40+ US cities (JLL), verified energy and emissions reductions keep your assets on the right side of the threshold.
When ventilation runs to real demand instead of a worst-case schedule, equipment cycles less and wears slower, deferring replacement capital and reducing the risk of failure. And verified performance data protects the asset's standing in valuation and financing conversations.
The problem

The cost of waiting keeps going up. We recover it.

The cost of energy and repairs rise every year. The longer fixes get deferred, the more energy is wasted, while the bill to catch up compounds.

  • Energy prices are rising.
    Commercial power is up 27% since 2020.

  • Repair costs are rising.
    HVAC repair contractor prices are up 32% since 2020.

  • Maintenance gets deferred.
    The U.S. now carries a $500B+ facility repair backlog, compounding roughly 3–5% a year.

Continuous Building Savings breaks the cycle, and every dollar you recover works twice.

For owners who lease, savings flow straight to NOI. At a 6% cap rate, each $1/yr saved adds about $17 in asset value.

For owners who operate, every recovered dollar becomes permanent budget for care, research, and paying down the backlog.
