2. True Costs of the EMS
Insufficient energy savings compared to new technology
Cyber security weaknesses
Lacks machine learning and predictive capabilities
No individual equipment performance insights
Inability to optimize airflow and air quality
Absenteeism, presenteeism and productivity costs

3. The EMS and Energy Savings
Expect 10% to 30% energy savings from a typical EMS.
By contrast, the predictive, proactive system creates 30% to 70% more energy savings.
Data from third-party Gas Technology Institute study comparing up-to-date EMS to smart HVAC solution.

4. The EMS and Cyber Security
EMS firms leave the bulk of cyber security up to you.
Your facilities, networks and customers are more vulnerable to cyber attacks from botnets.
What’s a botnet? A network of infected machines (a.k.a. “zombies”) that can collapse networks and compromise data.
What should be done?
Change default passwords on each connected device.
Place each device behind a strong firewalling router.
Enable the firewall function on the router.

5. The EMS Is Not Predictive or Proactive
EMS firms haven’t participated in the technology revolution since 2005… before the first iPhone debuted!
The EMS doesn’t correlate energy usage to your:
Building’s geographic orientation
Building usage patterns
Local weather (real-time or forecast)
It doesn’t optimize individual energy consuming pieces of equipment.

6. What Does the Predictive, Proactive System Do?
A predictive, proactive system uses cloud computing, machine learning and IoT capabilities to function smartly.
It optimizes energy efficiency, security and building automation, considering hundreds of data points every minute.

7. The EMS Doesn’t Optimize Indoor Air Quality
The EMS logs about 4 data points every minute. The predictive system logs several hundred per minute. The result? The EMS doesn’t optimize outdoor/indoor airflow or air quality.
The predictive system optimizes on the following points:
Local weather forecasts & real-time data
Building geographic orientation
Position of the sun
Humidity
Mean radiant temperature
CO2, CO, VOCs and particulate matter in the air

8. Air Balancing with a Predictive System
The heat maps below compare a typical EMS-controlled building (left) to a predictive system’s air temperature balancing (right).
Green is optimal for both guest comfort and energy efficiency.

9. vs. The EMS and Productivity
Researchers in the U.S. (Harvard, Syracuse & SUNY) and Europe (OFFICAIR) have found optimal indoor air quality in office buildings boosts cognitive abilities and productivity of workers.
The U.S. studies found:
26.4% higher cognitive test scores
30% fewer “sick building syndrome” symptoms
Productivity gains of 8% (≈ $6,500) per person per year, if ventilation rate is doubled from ASHRAE minimum standard using energy efficient HVAC
