Northern Weathermakers designs, installs, and supports building automation systems that give you real-time command over your HVAC performance — from a single thermostat replacement to a campus-wide BAS deployment. We work across all major control platforms and are not tied to any single manufacturer, which means we engineer each project based on what's right for your building, not what's right for a vendor quota. For Chicagoland facilities managing energy costs across extreme seasonal swings, a properly configured BAS can pay for itself through reduced runtime, optimized scheduling, and early fault detection.
Beyond energy savings, building automation directly improves occupant comfort. Instead of relying on manual adjustments or responding after complaints arrive, a well-programmed BAS maintains setpoints automatically and adapts to occupancy patterns — so tenants and employees experience consistent conditions throughout the day. Fault detection routines flag equipment problems early, often before they affect comfort or result in an after-hours emergency call. Energy trending data lets facility managers identify waste at the equipment level rather than waiting for the next utility bill. For Chicago buildings subject to the City's Energy Benchmarking Ordinance, a BAS also generates the consumption data needed for annual reporting — simplifying compliance without manual meter reads.
We design, install, and service BAS systems that put you in command of your facility's HVAC performance — from simple programmable controls to full remote monitoring and energy analytics. Our systems give you real-time visibility into every zone, every unit, and every dollar of energy spend. For multi-tenant buildings, that means tracking energy consumption by floor or tenant, identifying equipment that's running outside of scheduled hours, and catching small problems before they become emergency calls. We configure trend logging, alarm notifications, and dashboards tailored to how your facility team actually works — not a generic template that nobody checks. Real-time fault detection means fewer after-hours emergency calls because problems surface in a dashboard alarm before a tenant phones in a complaint. Scheduled operation automatically shuts down systems after business hours, eliminating the energy waste that comes from equipment left running in unoccupied spaces. Energy trending data lets you see exactly which air handling units or zones are driving consumption, giving you something concrete to act on instead of guessing from a monthly utility bill. Occupant comfort is maintained consistently without manual intervention — the BAS responds to changing load conditions and outside air temperature so your staff isn't chasing thermostat complaints all day.
We're not beholden to any single manufacturer. Our controls engineers integrate across platforms — Siemens, Johnson Controls, Honeywell, Trane, Carrier, ABB, and others — engineering each project to be the right solution for each distinct location. Customized turnkey control systems ready to install, with 24/7 remote monitoring included. Many Chicago-area buildings have controls from multiple eras and vendors — a Johnson Controls system from the 1990s in one wing, a Siemens system in another, and standalone thermostats in a recent addition. We specialize in bringing these disparate systems under a single unified front end so your team can manage the whole building from one screen. Our commissioning process includes full point-to-point verification and operator training so your staff is comfortable with the system from day one. A unified system simplifies training for facility staff — instead of learning three different interfaces, your team works in one environment. Troubleshooting is faster because every point and alarm is visible in the same place, reducing the time it takes to diagnose a problem from hours to minutes. Consistent comfort across different wings or floors becomes achievable because all zones are operating under the same sequences and schedules. The integrated system also makes it straightforward to generate consumption and runtime reports for management reviews, energy audits, or benchmarking submissions — data that would otherwise require manually pulling records from multiple sources.
A BAS that's installed but not optimized for your building's actual operation is a missed opportunity. Northern Weathermakers configures energy management strategies based on how your building actually runs — not textbook defaults. That includes demand-based ventilation that adjusts outdoor air based on occupancy, optimal start/stop routines that bring systems up to setpoint using the minimum runtime, supply air reset strategies that reduce chiller and boiler loads during mild weather, and chiller and boiler sequencing that stages equipment efficiently instead of short-cycling. For business owners and property managers, these strategies translate directly into lower utility costs and more predictable monthly operating expenses. For buildings subject to Chicago's Energy Benchmarking Ordinance — which requires annual energy reporting for larger commercial and residential properties — a well-configured BAS provides the consumption data needed for accurate reporting and helps improve your ENERGY STAR score over time. We review your utility history and equipment schedules before making recommendations, so the strategies we implement reflect what will actually move the needle for your facility.
Northern Weathermakers provides 24/7 remote monitoring for buildings under our service agreements. Our team watches your building systems around the clock, reviewing alarms and system anomalies before they escalate into comfort complaints or equipment damage. When an alarm fires at 2 a.m. on a Saturday, we're the ones receiving it — not your maintenance staff. We evaluate whether the condition requires an immediate dispatch, can be resolved remotely, or can wait until the next business day without affecting occupants. The result is fewer emergency service calls, lower after-hours labor costs, and fewer instances of equipment running in a degraded state for days before anyone notices. Facility managers gain peace of mind knowing that a qualified team is actively watching their systems, and tenants experience fewer comfort disruptions because problems get addressed before they hear about them. Remote troubleshooting also lets us diagnose many issues without rolling a truck, which means faster resolution times and less disruption to normal building operations.
Proper commissioning is the difference between a controls installation that works as designed and one that just technically powers on. For new installations, Northern Weathermakers performs full point-to-point verification — confirming that every sensor, valve, damper, and setpoint behaves exactly as the sequence of operations requires. For existing buildings, retro-commissioning identifies the gap between how the system was originally designed and how it's actually running today. It's more common than most business owners expect: overridden setpoints left from a past service call, disabled schedules that were never re-enabled, bypassed economizer modes, and heating and cooling fighting each other in the same zone. These aren't equipment failures — they're controls problems, and they don't require capital investment to fix. Retro-commissioning often recovers meaningful energy savings simply by restoring systems to their intended operation. We document every finding and every change made, so you have a clear record of what the system is doing and why.
A building automation system is only as effective as the people operating it. Northern Weathermakers provides hands-on training for your facility staff at the time of commissioning, covering how to navigate the front-end interface, adjust setpoints, respond to alarms, modify schedules, and pull reports. We don't hand over a generic user manual and call it done — we create custom documentation specific to your system, with your actual graphics, your actual equipment names, and step-by-step procedures for the tasks your team performs most often. After turnover, we offer ongoing phone and remote support for questions that come up during day-to-day operations. Trained operators make better decisions: they understand why a schedule is set the way it is, they recognize when something looks wrong, and they're less likely to resort to manual overrides that mask problems and waste energy. Investing in operator training extends the value of the BAS investment and results in a building that performs closer to its design intent over time.
From simple programmable controls to full building automation with remote monitoring — our controls engineers are ready to design the right solution for your facility.
