3. Energy Information Systems
 Also known as energy analytics platforms, building
dashboards, fault detection & diagnostics, ongoing
commissioning, or smart building systems
 Capabilities vary widely
 Not always a part of a building automation system (BAS)
 Can sit on top of BAS/BMS or can be fed data directly from utility
bills, sensors, meters, etc.

6. Research Can Help
 Lawrence Berkeley National Laboratory (LBNL) work:
 Framework (PDF) defining EISs and a matrix (XLS)
categorizing some tools
 Case studies (PDF)




University of California at Merced
LBNL office building
Walmart
Sysco
 Current work assessing costs and benefits
 PECI created an updated inventory of 14 tools with a
focus on measurement & verification
protocols/capabilities

7. But Do They Save Energy?
 Vendors claim up to 30 percent energy reduction
 LBNL case studies:
Site
EIS used
UC Merced
Automated Logic
Excessive overnight
Corp.’s WebCTRL gas use due to
nonzero pressure at
steam boilers
30% reduction in
average daily gas
use; avoided cost of
$4,500/month
Sysco
NorthWrite’s
Energy WorkSite
Retrocommissioning
and refrigeration tuneups
36% reduction in site
energy use
Lighting retrofit and
ventilation schedule
change
30% reduction in
whole-building
energy use
UC Berkeley No central EIS
Action/observation
Energy impact

Depends on:
 Skill/motivation/ability/authority of users
 Building type
 Building performance before energy analytics
