Building Automation ROI & Energy Savings

A practical guide for commercial property owners on calculating the financial return of a building automation system — energy, labor, and asset-value impact.

Energy savings of 20–40%

Demand-controlled ventilation, daylight harvesting, and occupancy-based HVAC scheduling routinely cut commercial energy use by 20–40%, with lighting alone often delivering 30%+ reductions versus static controls.

Lower facility labor cost

Centralized monitoring, automated fault detection, and remote diagnostics reduce truck rolls and manual rounds, freeing facility teams from routine inspection cycles.

Higher property valuation

Smart, certified buildings (LEED, ENERGY STAR, WELL) command higher rents, faster lease-up, and stronger appraised value — the automation backbone is a prerequisite for those certifications.

Daylight harvesting

Photo-sensor driven dimming continuously trims artificial light when daylight is available, producing measurable kWh reductions with no occupant action.

Demand-controlled ventilation

CO₂ and occupancy sensors modulate outside-air volumes in real time, eliminating the energy penalty of over-ventilating partially occupied zones.

Measurable payback

Most BAS retrofits target a 3–5 year simple payback. Combined utility incentives and demand-response revenue can compress that window further.

How to calculate BAS ROI

A defensible ROI model combines three streams: utility savings (kWh and therms avoided), operational savings (labor hours and reactive maintenance avoided), and asset-level gains (rent premium, occupancy, and exit cap-rate compression). Baseline the building’s current energy use intensity (EUI), model the post-retrofit EUI, and apply blended utility rates to project annual savings.

Where the savings come from

The biggest wins are HVAC scheduling and reset strategies, demand-controlled ventilation, daylight harvesting, and plug-load management. Together these typically deliver the 20–40% reduction range cited by ENERGY STAR and ASHRAE field studies.

Case studies

Representative results from BAS retrofits across Kansas commercial properties.

Class A Office — Wichita, KS

180,000 sq ft

HVAC scheduling, DCV, lighting controls retrofit

Savings: $94,000 / yr
Payback: 3.1 years

Replaced pneumatic controls with a unified BAS. Occupancy-linked VAV scheduling and CO₂-driven outside-air reset cut total kWh by 27% and natural gas by 19% in year one.

Multi-tenant Retail — Salina, KS

62,000 sq ft

Daylight harvesting + RTU optimization

Savings: $38,500 / yr
Payback: 2.4 years

Photo-sensor dimming on perimeter zones plus economizer fault detection on 14 rooftop units. Evergy commercial efficiency rebates covered 22% of project cost.

Light Industrial — Hutchinson, KS

240,000 sq ft

Compressed-air monitoring, lighting, HVAC

Savings: $142,000 / yr
Payback: 3.8 years

Real-time leak detection on the compressed-air loop and high-bay LED controls with occupancy sensing. Avoided two planned overtime maintenance shifts per month.

Kansas utility incentives

Programs that commonly stack with BAS retrofits across Kansas. Eligibility, caps, and rates change annually — Synapse confirms current program terms during feasibility.

Evergy Business Energy Efficiency Rebates

Evergy commercial electric customers (most of eastern & central Kansas)

Prescriptive and custom rebates for lighting controls, HVAC controls, VFDs, and energy management systems. Custom-track projects are paid on $/kWh saved with pre- and post-installation measurement.

Kansas Gas Service — Commercial Efficiency

Commercial natural-gas customers statewide

Rebates for high-efficiency boilers, condensing units, and controls upgrades that reduce therms. Often pairs with BAS scheduling and reset strategies.

Federal Section 179D Deduction

Owners of commercial buildings placed in service after upgrades

Up to ~$5.00/sq ft accelerated deduction for qualifying envelope, HVAC, and lighting improvements that meet ASHRAE energy targets — BAS-driven HVAC and lighting projects routinely qualify.

USDA REAP (Rural Energy for America Program)

Rural Kansas small businesses and agricultural producers

Grants up to 50% of project cost and guaranteed loans for energy-efficiency improvements, including BAS, controls, and lighting in eligible rural areas.

Kansas Industrial Energy Efficiency

Industrial and manufacturing facilities

Custom utility incentives for compressed-air monitoring, process controls, and submetering. Pairs well with BAS-integrated energy dashboards.
