Socially Driven HVAC for Personal Control

Socially driven HVAC optimization uses input from occupants in dynamic temperature management. Results showed 20% cooling savings, a 59% reduction in hot and cold calls and 83% of occupants more satisfied with their thermal conditions. View full-size infographic. [PDF - 258 KB]

GPG Findings 025, December 2015, SOCIALLY DRIVENHVAC OPTIMIZATION.  Opportunity: How is temperaturetypically controlled in commercial buildings? SET TO A PREDETERMINED RANGE OR “DEADBAND”Does not account for individual thermal preferences. Wastes energy by over-conditioning, particularly in unoccupied spaces. Technology: How does Socially Driven HVAC Optimization work? USES DIRECT INPUT FROM OCCUPANTS IN TEMPERATURE MANAGEMENT.TRACKS USER PREFERENCES OVER TIME, FINE-TUNES THE DEADBAND. Optimizes energy savings by widening the deadband when there is no occupant input Measurement and Verification: Where did M and V occur? OAK RIDGE NATIONAL LABORATORY assessed socially driven HVAC optimization at the Federal Building and U.S. Courthouse in Phoenix, Arizona. Results: How did SociallyDriven HVAC Optimization perform in M&V? 20% COOLING ENERGY SAVINGS, 47% HEATING SAVINGS, Over typical GSA facility.59%REDUCTION IN HOT AND COLD CALLS. 83% OCCUPANTS MORE SATISFIED WITH THERMAL CONDITIONS. Deployment: Where does M&V recommend deploying Socially Driven HVAC ptimization? PRIORITIZE WHERE THERMAL COMFORT IS AN ISSUE Energy savings will be greatest in facilities that are only intermittently occupied and have high energy costs and narrow deadbands. [PDF - 258 KB]
