Energy Exchange: Federal Sustainability for the Next Decade2

Background

• Statute and Executive Order 13693 instruct DOE to establish guidelines to meter Federal buildings for Energy (electricity, natural gas, and steam) and Water

• DOE issued guidance in November 2014 which serves as an update February 2006 Guidance

• November 2014 Guidance broadens the 2006 guidance established for metering of electricity to include both Statutory and E.O. requirements and to reflect current metering practices within the Federal Government

• The Metering Best Practices Guide (MBPG) was updated in March 2015 to support the Guidance and to reflect current practices.

Energy Exchange: Federal Sustainability for the Next Decade

• The metering guidance provides a two-step process for installation of meters in Federal buildings:– Step 1 sets criteria for determining Federal buildings for

which the installation of meters is “appropriate.”– Step 2 recommends a methodology for establishing a

prioritization process for the installation of meters at all “appropriate” Federal buildings

– The metering guidance requires an agency metering implementation plan be submitted to DOE FEMP within a year of the guidance being published. The agency plan shall consider resources required and prioritize metering implementation efforts for “appropriate” Federal buildings over the next five years

Guidance Overview

Energy Exchange: Federal Sustainability for the Next Decade

• Appropriate– The installation of energy and water meters is “appropriate” for

all Federal buildings that are not excluded under Step 1 of the guidance.

• Cost-effective– Studies show reduced operation and maintenance costs when

metered data is used to manage building energy consumption. These life-cycle cost savings exceed the life-cycle costs for installation and maintenance of the meters. Therefore, installation of meters is “cost effective” at all appropriate Federal buildings (including multi building installations).

Guidance Review – Key Definitions

Energy Exchange: Federal Sustainability for the Next Decade

• Exclusion criteria for Metering of Federal Buildings:– Planned to be sold or razed within the next five years– Leased or owned, but the agency does not pay the utility bill or does not pay the

lessor for utilities based on actual consumption– Building does not have an energy-consuming heating or cooling system or significant

process loads– Generates electricity that is sold commercially to other parties in the course of

regular business where installing meters would require an impractical shut-down of service

– Does not meet, or is expected not to meet, the de minimis thresholds set forth in the following tables

Step 1: Determine “Appropriateness”

WaterEnergy

Energy Exchange: Federal Sustainability for the Next Decade

• Install energy and water meters at all Federal buildings determined to be “appropriate” under Step 1

• As required by statute use, to the maximum extent practicable, advanced meters or advanced metering devices for energy

• DOE recognizes that agencies may not have resources for the immediate implementation of the guidance at all “appropriate” Federal buildings

• Agencies are expected to prioritize the order in which advanced meters and advanced metering devices are to be applied

Step 2 – Prioritization

Energy Exchange: Federal Sustainability for the Next Decade

For the purpose of maximizing cost effectiveness a recommended installation prioritization of advanced energy (electricity, natural gas, and steam) meters is provided:1. New Constructions and Major Renovations 2. Covered Facilities –Give highest priority to metering covered facilities that are known to

be the largest energy consumers. For covered facilities that are multi-building (campus) installations, agencies should prioritize meters, in addition to feeder lines (order follows)

a) All self-generated electricity and steam supplied to installation (campus), b) All agency data centers not planned for consolidation or closure, identified as part of

the Federal Data Center Consolidation Initiative and PortfolioStat,c) All other known energy-intensive building types (e.g., laboratories, hospitals, control

towers, and food services), d) All individual buildings 10,000 square feet or above, e) All large energy-consuming mission support processes (training systems, industrial

systems, communication transmitters, ship cold iron services, etc.), f) All High Performance and Sustainable Buildings, if not already captured above, and g) Remainder of “appropriate” buildings, largest first.

3. Non-Covered Facilities –Give highest priority to metering Federal buildings that are known to be the largest energy consumers. For facilities that are multi-building (campus) installations prioritize meters, in addition to feeder lines (order follows)a) Self-generated electricity, including renewable energy sourcesb) Data centers not planned for consolidation or closure identified as part of the

Federal Data Center Consolidation Initiative and PortfolioStatc) Individual energy-intensive building types (e.g., laboratories, hospitals, control

towers, and food services)d) Buildings 10,000 square feet or above e) All High Performance and Sustainable Buildings – if not already captured

abovef) Remainder of “appropriate” buildings

Prioritization for Energy Meters (Cont.)

Energy Exchange: Federal Sustainability for the Next Decade

For the purpose of maximizing cost-effectiveness it is recommended the installation of advanced water meters be prioritized as follows:

1) New Constructions and Major Renovations - install advanced meters at the supply for the building and for new landscape water use

2) Covered Facilities –Give highest priority to metering covered facilities that are the largest water consumers. For covered facilities that are multi-building (campus) installations prioritize the installation of meters in addition to supply lines (order follows)

a) Well water and internal supply lines b) Meters or other leak detection devices on distribution lines to identify system losses

(largest distribution lines first)c) Water-intensive facilities, and large landscape systemsd) Individual building 10,000 square feet or above,e) High Performance and Sustainable Buildings if not already captured abovef) Remainder of “appropriate” buildings

Prioritization for Water Meters

Energy Exchange: Federal Sustainability for the Next Decade

3. Non-Covered Facilities – Install advanced meters for each water supply line leading to the facility. Give highest priority to metering Federal buildings that are the largest water consumers. For facilities that are multi-building (campus) installations prioritize the installation of meters as follows:

a) Well water and other internal supply lines b) Meters or other leak detection devices on distribution lines to effectively identify

system losses (largest distribution lines first)c) Water-intensive facilities and large landscape systemsd) Individual buildings10,000 square feet or abovee) High Performance and Sustainable Buildings if not already captured abovef) Remainder of “appropriate” buildings

Prioritization for Water Meters (Cont.)

Energy Exchange: Federal Sustainability for the Next Decade

• Incorporate metered data into existing agency energy tracking systems and make data available to facility managers.

• Ensure that covered facility metered building energy and water data is entered into EPA’s ENERGY STAR Portfolio IAW Building Energy Use Benchmarking Guidance.

Using Metered Data

Energy Exchange: Federal Sustainability for the Next Decade

• Not later than 12 months from November 2014• Agency Plans shall include metering implementation for each

sub-agency (bureau, component, service, etc.) within its jurisdiction– Resource consideration and prioritization of “appropriate” Federal

buildings over the next five years. – Path forward for those remaining buildings to be metered following

the initial five years.• Submit plan to:

• Understand and be able to outline the key elements of a metering plan, including prioritization.

• Illustrate how to use metered data to identify energy and cost saving opportunities.

• Achieve a high-level understanding of metering technologies, equipment, and applications.

• Describe the methods and approaches for building-level, distribution-level, and end-use metering.

• Explain the different data communication options for metered data.

Objectives of Metering Best Practices Guide
