Global Commitment: ZNE

Over the next two decades, an area roughly equal to 60% of the total

building stock of the world is projected to be built and rebuilt in urban

areas worldwide. This provides an unprecedented opportunity to

reduce fossil fuel CO2 emissions by setting the global building

sector on a path to phase out CO2 emissions by 2050.

Net Zero Energy as an

Organizing Principle

• Puts programs and policies in the context of an

inspiring, long-term goal

• Can replace confusing, dueling metrics

• Forces a strategic, integrative approach

• Makes agencies examine everything, ask

questions and seek creative solutions

• Demands breaking down stovepipes

The Evolution of Federal

Net Zero Energy Policy

• Energy Independence & Security

Act (EISA) (2007):

– New buildings = zero fossil fuel use by

2030

• GSA Green Building Advisory

Committee (2014):

– Proposes aggressive Federal NZE goals

• Executive Order 13693 (2015):

– New bldgs: NZE & net zero water or waste

(where feasible) by FY 2030

– Existing bldgs: Set goals for NZ energy,

water &/or waste bldgs

• GSA Public Bldgs Service (2016):

– 25 NZEBs by 2025

• Long-term perspective:

– Net zero campuses & portfolios

– We’re making it happen

– Saving energy and cutting carbon without sacrificing budgets,

mission or aesthetics

Pilot Installations


Holistic Approach Includes:

Thermal & electric energy

Dramatic demand-side energy use reduction

Right mix of energy generation technologies & strategies that also increase energy

security

Area/building clusters served by smaller Central Utility Plants & microgrids

Flexible implementation strategies based on potential technology innovations &

mission changes

Enhances energy awareness & promotes behavior/cultural change

Net Zero Energy

Net Zero ENERGY: Reduce overall energy use,

maximize efficiency, implement energy recovery &

cogeneration opportunities, & then offset the remaining

demand with the production of renewable energy from

on-site sources, such that the Net Zero energy

installation produces as much renewable energy as it

uses over the course of a year.

Best Practices – Energy

Conduct thermal building envelope analysis

IR thermography identifies heat loss & enables

targeted repairs

Reduce energy use through energy

management control systems (EMCS)

Provides ability to control energy-consuming devices

(e.g., fans, compressors, boilers, chillers, pumps, lights)

Can also be used for demand reduction

Hire resource efficiency managers (REMs)

REM’s goal is to reduce consumption & cost of energy

Work with existing staff to enhance conservation efforts

Troop Barracks

EMCS Dashboard

Oregon NG REM


Pursue alternative financing mechanisms

Energy Savings Performance Contracts (ESPCs) & Utility Energy

Service Contracts (UESCs)

• The Energy Services Company (ESCO) or Utility Provider funds energy

projects that are paid back with cost savings generated over the contract

term or Power Purchase Agreement

Conduct energy master planning

Integrates energy efficiency & renewable

energy goals & planning into the Real

Property Master Plan

Enables renewable energy options that

aren’t feasible at a single building (e.g.,

central utility plants to serve a Brigade

complex)

Why Influence Behavior?

Army spent $1.5 B on utilities in FY15

DOE estimates that behavior change

can reduce energy costs by 3%~10%

Savings can be applied to other

critical mission needs

Reduction helps meet federal

sustainability mandates

Good behavior in the workplace

carries over to home

Fosters a sense of community pride

among Soldiers and units


Behavioral Change

Leadership support Leadership attention

Positive recognition Negative recognition

Role models Mock bills

Army Net Zero Directive

Net Zero Installations Policy:

Army Directive 2014-02

Implementation Approach:

Initiate, Assess, Roadmap & Implement


Lessons Learned

• Leadership support is required

• Net Zero does not equal energy security

• Goals and mandates require incentives and enforcement

• Behavior/culture change is also needed

• Holistic planning along with continual flexibility is necessary

• Construction designs need to sync with net zero goals

• Thermal NZE is the most difficult to accomplish

• Projects are difficult at many installations due to costs

• Implementation support is critical to success

• Must account for tradeoffs between water, energy, and waste

• High levels of RE can require special utility agreements

An engaged and motivated team is the key differentiator

ZNE* Policies Across Borders

NZE vs. nZE vs. VLE

• While the US has had “NZE” (Net Zero Energy”, though moving toward just “ZE” with new DOE definition?)…

• ...In Europe the term is “nZE” or “nearly” Zero Energy – with a different definition in each EU Member State

• In some venues, discussions are about “VLE” (very low energy) to avoid confusion about definitions

Outside of US, Most Activity in Europe

• European “Energy Performance of Buildings Directive” (EPBD) Recast (Directive 2010/31/EU) provides “framework definition” for Nearly Zero-Energy Buildings; details left to Member States

• A variety of European Union (EU) and NGO publications and efforts tracking progress

APEC Energy Working Group NZE Review

• Several countries participated

in recent Asia-Pacific

Economic Cooperation

(APEC) Energy Working

Group: “Nearly (Net) Zero

Energy Building Project”

• China Academy of Building

Research serves as convener

and secretariat for the project

See http://www.egeec.apec.org/egee-and-c-reports-to-ewg/net-zero-energy-building-workshop-china/

APEC NZE Findings

• Japan, Korea, and the United States have issued policies and set up clear and aggressive long-term goals for NZEB, and Japan and Korea have established financial and taxation policies to speed up development

• Project noted different definitions, and highlighted current obstacles and barriers to wider adoption

http://www.egeec.apec.org/egee-and-c-reports-to-ewg/net-zero-energy-building-workshop-china/

5/18/2016

40

Is Much Comparable?• No consistent definitions

• Definitions driven by policy initiatives; local context is critical• No driving prospect for harmonization• Without common definitions, very little is comparable

• Many targets, but no consistent tracking of market progress• Perceptions of growing market acceptance and progress, but

no standardized tracking of any defined metrics • EU activity farthest along; market reporting should improve in

coming years• In both US and elsewhere, need for more data on “verified”

performance

Key Takeaways

• Lots of activity – mostly Europe and North America, but growing interest beyond

– hard to compare relative progress because of substantially different definitions

• Growing number of market tracking initiatives globally

– With more market traction, this will continue to grow

– Potential for more linkage of tracking projects
