A combination of software, data acquisition hardware and communication systems used to collect, analyze and display building information. This information is used to help commercial building energy managers, facility managers, financial managers and electric utilities reduce energy use and costs.
Military, government and commercial facility managers face the daunting task of managing electric, gas and water costs; complying with federal and military mandates; implementing energy efficiency programs; and deploying new technologies such as smart meters, renewable energy sources and electric vehicles. Compounding this challenge is the difficulty of integrating information in a timely fashion from multiple systems, buildings and bases.
Improved Enterprise Energy Management (EEM) tools support energy management at the corporate level. Energy managers can view energy use across thousands of buildings in real time. Instead of managing each building individually, companies can manage multiple facilities at the same time. Improved tracking and analysis tools help energy managers meet corporate efficiency goals, achieve mandated energy-intensity targets, and track resource consumption and carbon emissions.
Savings vary by type of facility, degree to which energy management activities have already been institutionalized, and energy intensity. One EEM solutions company suggests that energy costs can be reduced by 2% to 15% for large, complex organizations. A case study for Lund Food Holdings in Minnesota indicates energy savings of 10% at a chain of 22 grocery stores.
Status:
Baseline Description: Unmanaged commercial building Baseline Energy Use: 16.7 kWh per year per square foot
Taken from 2007 CBSA (http://neea.org/docs/reports/2009NorthwestCommercialBuildingStockAssessment021CA220F212.pdf?sfvrsn=10). Used overall average of all commercial buildings, since any of them can use integrated design.
"Typical" Savings: 10% Energy Savings Reliability: 2 - Concept validated
Case studies show 2 to 15% savings. Results will vary greatly depending on the existing conditions, how well the system is implemented, and on the attitude of the energy manager, management, and other participants.
Energy Use of an Emerging Technology is based upon the following algorithm. Baseline Energy Use - (Baseline Energy Use * Best Estimate of Energy Savings (either Typical savings OR the high range of savings.))
Simple payback, new construction (years): N/A
Simple payback, retrofit (years): N/A
Cost Effectiveness is calculated using baseline energy use, best estimate of typical energy savings, and first cost. It does not account for factors such as impacts on O&M costs (which could be significant if product life is greatly extended) or savings of non-electric fuels such as natural gas. Actual overall cost effectiveness could be significantly different based on these other factors.

Technical Advisory Group: 2011 Energy Management TAG (#4) TAG Ranking: 46 out of 59 Average TAG Rating: 1.81 out of 5 TAG Ranking Date: 09/29/2011 TAG Rating Commentary: This may only apply to large commercial. Small commercial tends to have a different decision-making structure. Could be applied on a smaller scale though? Not a technology per se. Industry already is doing this. GREAT if BPA can pull it off. Very few people know how to do this - it takes special skill. This directly relates to Behavioral Change efforts. I've been involved in this process twice with impressive results.
