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.
