How Much Does a Building Automation System Cost?

July 13, 2021 By Mid-Atlantic Controls 5 minute read

There are a few significant factors that facility managers need to consider when trying to determine the cost of a new building automation system:

  • Size (total square footage)
  • Type of building (s)
  • Integratable systems like lighting, HVAC systems, fire, security, and access control

One important consideration is understanding that an open, non-proprietary building automation system platform translates into a higher ROI.

For example, a facility manager can aggregate all of that data and analyze it for:

  • Energy savings
  • Operational efficiencies
  • Preventive maintenance
  • Many other building performance improvements

When done correctly, building owners can see a higher return rate, usually within five years.

Cost for Building Automation Systems

Generally speaking, the cost of building automation systems is anywhere between $2.50 and $7.50 per square foot.

In addition to the factors above, the cost can also be affected by:

  • Whether or not you’re installing the system in a new building.
  • If it’s a new system in an older building.
  • If it’s an upgrade from an older legacy building automation system.

For example, it is easy to understand why a data center would cost more per square foot than a typical office building.

Benefits of New Building Automation Systems


A new, open-platform system allows you to capitalize on the latest smart building technologies. This gives you ample options when it comes to price since it’s not locked into one company’s offerings.

A new building control automation system also allows you to integrate systems, oversee performance, and leverage the data produced by each system.

This could mean massive energy savings and incredible operational savings through efficiencies and decreased downtime for repair for many buildings.

Installation of New Building Automation Systems

New construction is the ideal time to consider installing a building automation system.

Working with a BAS company early on will save money in initial costs (no retrogrades later). This will help guide you on the ideal placement of sensors throughout the facility. This enables the building automation system to optimize all systems used within the facility.

Vykon Building and Energy

Picking an open and integrative system, like Tridium, enables the optimization of buildings, data centers, industrial plants, and even entire city infrastructures.

Tridium provides a software infrastructure to integrate diverse systems and devices into a unified platform that you can manage over the Internet.

Tridium also offers Vykon Building and Vykon Energy that will enable you to integrate proprietary and otherwise incompatible products into a unified enterprise solution. This will allow you to measure, manage, and control facilities and energy applications from anywhere in the world.

Building Automation System Legacy Upgrade

If you want to upgrade from an older legacy system, don’t let anyone tell you that this isn’t an option. Ultimately, the company you work with will be one of the most critical decisions, especially for a building automation system legacy upgrade.

A company specializing in building automation system legacy upgrades can evaluate your current system and provide cost estimates for upgrades. They will pinpoint areas where a legacy system is lacking and define the benefits of upgrading or migrating to a newer system.

Their goal is to help extend the life of the existing building automation system and preserve as much of the initial investment as possible. A professional may also be able to provide a migration path that allows for an upgrade over time.

Benefits to Legacy Building Automation System Upgrades

When upgrading a legacy system, building operators can benefit from technology improvements without losing the initial investment in the original building automation system.

Some of the key benefits of upgrading a legacy system include:

  • Preserving initial BAS and EMCS investments
  • Upgrading older building automation and energy management systems
  • Taking advantage of current technology with your existing system
  • Removing ties to proprietary systems and increasing upgrade options
  • Reducing expansion, service, and maintenance costs of existing BAS or EMCS
  • Allowing Multi-Building and Campus Integration of different systems
  • Integrating multiple systems allows the streamlining of building management.

Building Automation System ROI & Data Analytics

One of the great benefits of building automation systems is the wealth of valuable data your building produces daily. Facility and property managers can then visualize the real-time data from each of the building’s systems on their laptops or iPads.

You can leverage building automation system data in many ways, including:

  • Energy savings
  • Access control
  • Security
  • Maintenance
  • And more

From lighting to HVAC, there are many ways that you can achieve significant cost savings. For example, according to research, commercial buildings account for 20% of all the energy used in the U.S.—and around 30% of that goes to waste due to inefficiencies.

More Savings With Building Automation Systems

Budgeting for a BAS Upgrade

When you work with a company with experience integrating systems within a BAS platform, you’ll realize greater immediate and long-term savings. For example, you can:

  • Track building usage patterns.
  • Track equipment lifecycle patterns.
  • Detect anomalies in production.
  • Pinpoint equipment that needs to be repaired or replaced before it breaks down.

You can save a tremendous amount of money by reducing downtime, maintenance, and repair costs for industrial-type buildings or production facilities.

Choosing a Building Automation System

An automated building system provides you with complete control over your facilities with real-time access to the various functions that control and manage your equipment. This allows for even more significant savings and efficiencies.

Working with Mid-Atlantic Controls for your building automation system project will ensure that you have access to the latest and greatest state-of-the-art technology that’s backed up by our decades of experience and expert advice.
