1 Session 7: Building Automation and Operation Controls Building Automation Building Trends and Industry Perspective on Future Landscape Michael Facente Automated Logic Corporation August 10, 2016 Rhode Island Convention Center Providence, Rhode Island

2 Building Automation Trends and Future Landscape What is a Building Automation System? What are the primary goals of a Building Automation System? Basic and advanced energy saving strategies of a Building Automation System. The increasing focus on Indoor Air Quality The evolution of the Building Automation as a platform. Fault Detection & Diagnostics/Analytics Enhanced Data Visualization 2

3 Components of a Building Automation System Building automation is the automatic centralized control of a building's heating, ventilation and air conditioning, lighting and other systems through a building management system or building automation system (BAS). 3

4 Primary Goals of a Building Automation System 4

5 Basic Energy Saving Strategies 5

6 Advanced Energy Saving Strategies 6

7 Indoor Air Quality on Cognitive Function Historically the focus has been on energy savings because it is easily quantifiable Highest cost of a building is the people Energy programs affect comfort and many studies show that comfort affects productivity Greater emphasis on features that measure and report on IAQ 7

8 Early Studies on Comfort and Productivity Florida insurance company increases productivity $2/worker University of Denmark found math improvements of 28%, reading comprehension 24% Rocky Mountain Institute found that in some buildings increasing productivity 1% could exceed total energy spend for a facility *references at end of presentation

9 Comfort Measurement Cognitive Function (COGfx) Study Harvard T.H. Chan School of Public Health s Center for Health and the Global Environment SUNY Upstate Medical University Syracuse University Results: Found that improved indoor environmental quality doubled occupants cognitive function test scores. Cognitive function scores were significantly better in Green+ building conditions compared to the Conventional building conditions function test scores doubled/

10 The BAS as a Platform Platform group of technologies that are used as a base upon which other applications, processes or technologies are developed. BAS evolving over time: Integrate to many different systems Programs/aps being developed Aggregates a large amount of data Creates information from data 10

11 The BAS as a Platform Integration WATER Smart meters, use/flow sensing HVAC Fans, variable air, volume, air quality FIRE Functionality checks, detector service 24/7 MONITORING Condition monitoring, parking lot utilization ACCESS/SECURITY Badge in, cameras, integration perimeter, doors, floors, occupancy LIGHTING Occupancy sensing ENERGY Smart meters demand response ELEVATORS Maintenance, performance Drivers and Enablers: Integration Audiences are changing\expanding Data requirements growing Complex systems & requirements IT technology Open protocols Industry culture (technical) Business synergy 11

13 The BAS as a Platform Programs & Apps Interesting phenomena third party apps and programs being developed for BAS platforms Analytics Crowd sourced occupancy comfort phone apps Remote automated check out tools Energy curtailment protocols/programs 13

14 BAS Fault Detection and Diagnostics 14

15 BAS Fault Detection and Diagnostics FDD in the industry Subject of much research Sometimes called building analytics Sometimes called continuing commissioning Some are real time Some are historical All cost money For this discussion FDD Real time Living in the distributed control systems Algorithms transcribed into code Delivered as BAS alarms Often includes dashboards & reports Leverages existing BAS infrastructure 15

16 BAS Analytics Concept Building Automation System DATA DATA Analytics Software 16

17 BAS Analytics Concepts Building Automation System DATA DATA Analytics Software Extremely capable Can run complex, system-wide rules Can employ optimization Can mine historical data Can be costly Data clean up sometimes a challenge Can be complex Rules may overlap with FDD 17

18 Advanced Data Visualization 18

19 Advanced Data Visualization 19

20 Advanced Data Visualization 20

21 Advanced Data Visualization 21

22 BAS as a Platform Cornell University 250+ buildings Trending and storing 500k points Terabytes worth of data Native lighting control as well as lighting integration Native lab control as well as lab integration Integrated into campus work order system Integration to fire, security, and legacy BAS systems Integrated into campus wiki Data exported and exposed to students for research and visualization 22
