3 Agenda What What is BAS What is Analytics Metering and benefits How they fit together Why and How Challenges Costs Benefits Rules Value to owner and examples

4 BAS Building automation system. AKA BMS, Control system, Johnson, Honeywell, ATC, Struxtureware, etc. It s the parent for building systems. Security, HVAC, metering, etc. Controls the equipment Light trending ability, troubleshooting Scheduling

5 AHU Typical AHU Damper control Fan Speed Control Valve operation EF s, status incorrect Simple date

6 Scheduling Easy slider set up Weekly with multiple options

7 BAS Limits Many platforms Java, HTML5, thin clients Windows only, Some mac, browser vs. thin clients Systems Small computers, low memory, low storage cannot trend high amounts Enterprise server, Automation server Networks Ethernet, N2, R2, BacNet, Lon Slow, Fast, a pain.

8 BMS Questions?

9 Building Analytics Building Analytics is like the babysitter for the BAS and Metering. Pulls data from the Enterprise servers, building controllers or from the unit controllers.
