The Light Commercial HVAC Automation Market

• Recent Studies estimate the market at approximately 17,000 jobs installed in 2003

• Growth Estimates are expected to be near 8% annually

• By 2007, that translate to nearly 21,000 light commercial opportunities!

Current Decision Drivers for Light Commercial Building Owners

• Cost of Operations– Energy savings = Saves Money– Lower maintenance expenses– Reduce/delay cost of capital improvements– Reduce tenant turnover and vacancy (loss of revenue)

• Comfort– Poor Comfort levels is Number one reason for tenant relocation

• Compliance – ASHRAE standards – State and Local codes

HVAC Automation Meets those Needs

• Controlling overhead costs, one of the largest being HVAC

• Efficiently maintaining processes and productivity Through temperature management and alerts

• Employee Productivity and Comfort• Providing a cost effective and reliable solution

What is Building Automation

• Automatic control of sub systems through the use of central processor– HVAC– Lighting– Security– Fire– Closed Circuit TV– Audio/Video

Why install HVAC Automation• Operational savings

– HVAC is typically the largest energy consumer in a building, providing the greatest opportunity for dollar savings and ROI

– Can be controlled from 1 location– Just in time maintenance– Set backs– Energy Management System– Security (temp lock outs)

• Centralized Control– Remote access – Convenience – Energy Management

What to Look For

• Buildings with Multiple Zones– Multiple Pieces of Equipment (RTU or Split)– Zone Control Systems on a Single piece of

equipment• Companies with Multiple Buildings or

“Campuses” that desire one main control point

• Customer wants an affordable and easy to operate solution

Typical Applications

• Day Cares• Churches• Schools• Office Buildings• Retail Stores• Manufacturing• Restaurants• Medical• Dental• Nursing Homes• High End Homes

What Does the Customer Get

• Energy Savings through thermostat set-back, up to 18% according to ASHRAE

• Centralized Control allows the building owner to control all thermostats from a single location

• Thermostat Security through the use of passcode protection ensures savings

There are a lot of ways to Automate, which should I choose?

• There are many ways to automate ranging from Thermostats with Lock Boxes to full blown Building Automation Systems (Johnson Controls Metasys, Honeywell Excel 5000 & LCBS, Alerton)

• Aprilaire is the “right” solution for Light Commercial Applications, more advanced and offering more features than a standard thermostat, but more economical and simple to operate than the large systems.
