See your building’s performance. Reduce runtime. Lower energy spend.

Most commercial buildings run on manual setpoints and reactive repairs. A BAS changes that — giving your facility team real-time visibility, automated scheduling, and the data to catch equipment drift before it becomes a failure.

Manufacturing plants, medical office buildings, data centers, schools, and Class-A towers across Chicagoland are running without a complete picture of their buildings.

Facility managers who have never had a building automation system describe the same problem: equipment runs outside schedule and nobody knows, zone complaints are impossible to diagnose remotely, and failures surface when a tenant calls — not before.

A properly designed and integrated BAS changes the operating picture. You get a single view of every piece of equipment in the building — setpoints, runtime, alarms, trends — and the ability to make adjustments without dispatching a tech to the roof.

Medical office buildings

Comfort SLAs, critical zone control, IAQ monitoring, redundancy planning for patient-facing spaces

Manufacturing & industrial

Process environment control, exhaust and makeup air automation, mixed-vintage equipment integration

Schools & higher ed

Occupied/unoccupied scheduling, energy reporting, summer shutdown sequencing

Data centers

Precision cooling verification, hot aisle monitoring, 24/7 alarm escalation

Class-A office & CRE

Tenant comfort SLAs, after-hours HVAC requests, energy benchmarking for ownership reporting

Distribution & logistics

Dock door conditioning, large-volume scheduling, utility demand management

What NW delivers on a BAS engagement.

We don’t sell a BAS platform. We design the system that fits your building, integrate it with your existing HVAC, and stay on the monitoring side once it’s live.

BAS design & specification

Control sequence design, point list development, hardware specification — sized for your building, not a catalog default.

Integration with existing HVAC

Existing RTUs, chillers, AHUs, VAVs, and boilers wired and commissioned into the BAS without a rip-and-replace.

Legacy system retrofits

Buildings with pneumatic controls or older DDC can be migrated incrementally — no full-building shutdown required.

24/7 remote monitoring

Alarm routing, fault detection, and remote setpoint adjustment. Issues surface before tenants call.

Commissioning & documentation

Functional performance testing, as-built point lists, operator training, and O&M documentation you can actually use.

Ongoing BAS service

Graphics updates, trend logging review, firmware management, and control sequence tuning as your building changes.

The locked-in BAS problem — and how NW avoids it.

Most BAS contractors are aligned with a single platform. When equipment changes, or you want competitive pricing on a service call, you find out the system only runs on one vendor’s tools — and only their techs can touch it.

A single-vendor BAS contractor

  • Proprietary platform tied to one manufacturer
  • Ongoing service requires their techs — no competitive options
  • Expansion or equipment swap requires their hardware
  • Software licenses and upgrades billed separately
  • No path to transition — switching means starting over
  • Support escalation routes to a national center

The NW approach

  • Manufacturer-independent — we spec the platform that fits your building
  • Open protocols (BACnet, Modbus) wherever possible — no proprietary lock-in
  • Existing equipment integrated before any new hardware is quoted
  • Pricing and scope reviewed with you before any change order
  • Northbrook-based dispatch — service calls don’t route through a national center
  • Employee-owned team with long tenure — same tech, same building

How a BAS engagement starts.

Step 1 — Site walk. A controls tech walks the mechanical rooms, rooftop units, and occupied spaces. We map what’s controlled and what isn’t.

Step 2 — Existing conditions report. We document every controlled point, the current control sequences (or lack of them), and equipment running without feedback loops.

Step 3 — Design & scope. Control sequence design, point list, hardware spec. Reviewed with your team before anything is ordered.

Step 4 — Installation & commissioning. Wiring, programming, functional testing. We don’t hand off until every point responds.

Why NW for building automation.

77 years of Chicagoland commercial HVAC means we understand what’s actually in older buildings — pneumatic controls, mixed-vintage equipment, non-standard piping. BAS work that starts with an honest site walk goes differently than BAS work that starts with a catalog quote.

Manufacturer-independent. We’re not pushing a platform because we carry it. We specify open-protocol systems and tell you exactly what the tradeoffs are.

Employee-owned. The tech who wires your BAS has equity in the company. It shows up in the quality of the as-built documentation and in how they answer the phone when something trips at 2 AM.

Northbrook-based. Your building is in Chicagoland. We’re here — not routed through a regional office.
