Zero Energy Policy Resources

Learn from best practice examples how to successfully implement policy to achieve zero energy goals.

Policies & Goals   Programs   Codes & Stretch Codes

 

In this section you will find leading examples of policies and goals of states and local jurisdictions (strategic plans, energy plans, and climate action plans), programs working toward zero energy, and state and local jurisdiction energy codes and stretch codes.

Policies and programs have the ability to dramatically change the landscape for zero energy buildings. There is an increasing market interest in zero energy, and policies and programs can foster and grow that interest through leadership, direct support, and the reduction of risks and uncertainties. States and cities are taking the lead on implementing mandatory zero energy policies. Many leading state and local governments are working to pursue goals via methods ranging from standards imposed on government buildings, to codes regulating all new construction within the state. National leaders include California, Washington State, New York, Massachusetts, and Vermont. Building policies for the federal government within agencies have also made large strides in recognizing the importance of zero energy and working toward this goal. Aggressive targets for building energy use at all levels encourage architects and engineers to design for zero energy.


POLICIES & GOALS

California Long Term Energy Efficiency Strategic Plan
In 2008, the CPUC adopted California’s first Long Term Energy Efficiency Strategic Plan, presenting a single roadmap to achieve maximum energy savings across all major groups and sectors in California. The comprehensive plan is the state’s first integrated framework of goals and strategies for saving energy, covering government, utility, and private sector actions. It calls for 50% existing commercial buildings to be zero energy by 2030, new state buildings and major renovations zero energy by 2025, and 50% existing state owned buildings zero energy by 2025.

Vermont’s Comprehensive Energy Plan
Vermont’s Comprehensive Energy Plan includes three primary goals: (1) to reduce total energy consumption per capita by 15% by 2025, and by more than one third by 2050; (2) to meet 25% of the remaining energy need from renewable sources by 2025, 40% by 2035, and 90% by 2050; and (3) by 2025, meet target end use sectors of 10% renewable transportation, 30% renewable buildings, and 67% renewable electric power.

Austin Energy Resource, Generation and Climate Protection Plan
The Austin City Council adopted the Austin Climate Protection Plan (ACPP) in 2007 to build a more sustainable community. Every City department was subsequently tasked to create action plans intended to ensure that departmental operations were consistent with the ACPP. Austin Energy developed a Resource, Generation and Climate Protection Plan to 2020 to meet these objectives, which was approved by City Council in 2010 and later refined to include affordability metrics. In 2014, City Council passed a resolution that recognized the need to further accelerate the reduction of greenhouse gas emissions beyond the 2007 ACPP standards and set a goal of reaching net zero community-wide greenhouse gas emissions by 2050 or sooner. Additionally, the City Council appointed the 2014 Austin Generation Resource Planning Task Force to make recommendations on the utility’s generation mix to 2025 and to further set the energy sector of the City of Austin on a glide path to achieve the emissions standards set forth in the 2014 ACPP.

Greenovate Boston 2014 Climate Action Plan Update
The Greenovate Boston 2014 Climate Action Plan Update builds upon seven years of work in reducing citywide greenhouse gas (GHG) emissions and preparing for the unavoidable impacts of climate change. Beginning with the 2007 Executive Order, the City of Boston set GHG reduction goals of 25 percent below 2005 levels by 2020 and 80 percent by 2050 for municipal operations, and requires the City to plan and prepare for the impacts of climate change.

Cambridge Net Zero Action Plan
The Cambridge Net Zero Task Force was assigned to study the technical aspects of greenhouse gas emissions from buildings in greater detail and develop comprehensive, actionable, long and short term recommendations. In June 2015, the Net Zero Action Plan was adopted by City Council. The report addresses the following topics: reduction of greenhouse gas emissions from the built environment, improvement of energy efficiency and conservation in existing and new buildings, support for renewable energy generation both on- and off- site, and best practices to engage and educate users and influence occupant behavior.

City and County of Denver Climate Action Plan 2015
Denver’s 2015 Climate Action Plan is intended to create a more resilient city by building upon existing efforts to limit the most severe effects of climate change through new strategies to reduce greenhouse gas emissions. In this plan, Denver sets a new long-term goal, in alignment with climate science, to reduce community greenhouse gas emissions 80% from its 2005 baseline by 2050.

Eugene Climate Recovery Ordinance
The city of Eugene aims to cut in half community fossil fuel use by 2030. Its climate action goals focus on reducing carbon pollution relative to historic levels. The city recognizes the need to reduce carbon pollution to at or below 350 parts per million in the atmosphere. The 2016 updated Climate Recovery Ordinance sets a goal to have Eugene’s emission levels at a 350 ppm level by 2100. At the municipal level, Eugene is targeting carbon neutral city operations by 2020. This is to be mainly achieved by an overall 55% reduction in GHG emissions from 2005 levels by 2020, with emissions offsets covering the gap between that reduction and all the way to net zero.

Fort Collins 2015 Climate Action Plan Framework
To date, Fort Collins has reduced its greenhouse gas emissions five percent below 2005 by partnering, educating and inspiring the community. Now, pursuant to City Council Resolution 2014-028, this Climate Action Plan (CAP) Framework has been developed to explore what it would take to achieve reductions in community GHG emissions of 20 percent below 2005 by 2020, 80 percent below 2005 by 2030, and carbon neutrality by 2050.

Pima County Net-Zero Energy Building Standard
The Net-Zero Energy Building Standard project was sponsored by the City of Tucson Office of Conservation and Sustainable Development. Pima County Development Services, Building Safety and Sustainability was the principle research group with assistance from the University of Arizona College of Architecture and Landscape Architecture and Tucson Water. The Net-Zero Energy Standard has a prescriptive residential section and a prescriptive commercial section covering apartments, office and retail. These building types represent approximately 30% of total energy use in the metro area. The Net-Zero Energy Standard also has a performance section for both residential and commercial that will allow buildings that cannot use the prescriptive path to achieve a net-zero certification by using energy modeling software.


PROGRAMS

C40 Cities Climate Leadership Group
The C40 Cities Climate Leadership Group, after more than a decade of operation, now connects more than 80 of the world’s greatest cities, representing over 600 million people and one quarter of the global economy. Created and led by cities, C40 is focused on tackling climate change and driving urban action that reduces greenhouse gas emissions and climate risks while increasing the health, wellbeing and economic opportunities of urban citizens.Carbon Neutral Cities Alliance (CNCA)
Cities striving for carbon neutrality recognize that averting the worst impacts of climate change will require cutting GHG emissions by at least 80% by 2050. Because urban areas account for nearly three-quarters of humanity’s emissions, reaching this goal will depend in large part on our ability to reimagine and reinvent cities in ways that promote economic prosperity, social equity, enhanced quality of life, and climate resilience. The Carbon Neutral Cities Alliance (CNCA or “Alliance”) aims to address what it will take for leading international cities to achieve these deep emissions reductions, and how these cities can work together to meet their respective goals more efficiently and effectively.

This program engages the community, educates the building industry, and provides huge value in reducing the energy footprint in the region. The intent of the Zero Energy Pilot Program offering is to encourage building owners in the Consumers Energy territory to pursue whole building energy efficiency on their projects. The program encourages zero energy as a post-occupancy, measurable goal, by providing a suite of incentives (varying in dollar amount and requirements) to fund engineering support, cost-benefit analysis and post-occupancy measurement and verification.

Net Zero Energy Building Program
The Illinois Clean Energy Community Foundation’s Net Zero Energy Building Program will award grants to new construction or retrofit projects that achieve site net zero energy performance, or better, over the course of a year. Buildings must, at a minimum, offset all of their energy consumption with on-site generation from renewable resources. Grants will be paid incrementally, with full payment contingent on actual performance. The program goal is to encourage exemplary buildings that bring together beautiful design and careful construction to maximize energy efficiency, showcase renewable energy and, by educating the public and professionals, help pave the way for a larger shift in the building sector. The Foundation aims to fund projects that demonstrate that net zero energy buildings are realistic and achievable. These flagship projects will add to the knowledge base on Net Zero building design and operation.

Statewide Energy Efficiency Collaborative ZNE Hub
California’s Statewide Energy Efficiency Collaborative (SEEC) provides support to cities and counties to help them reduce greenhouse gas emissions and save energy. The ZNE Hub, maintained by SEEC, serves as a comprehensive resource for local governments to better understand the current policy landscape and the range of resources currently available. It includes a general overview of zero energy implementation for local governments, broken down by common steps, and a compilation of barriers, best practices, case studies, and key references.


CODES & STRETCH CODES

CALGreen Code
Part 11 of the Title 24 Building Standards Code is the California Green Building Standards Code, also known as the CALGreen Code. This is the first statewide green building standards code in the nation. The 2016 CALGreen Code became effective on January 1, 2017. All newly constructed buildings on new or existing sites shall comply with the CALGreen Code, Chapter 5. A CALGreen Code submittal to the DSA must include California Energy Code (Title 24, Part 6), Outdoor Water Regulations, and all other DSA mandatory measures.

Delaware Title 16: Chapter 7602 Code for Energy Conservation
This code requires that the Delaware Energy Office, or its successor, in consultation with the Green Building Council of the Home Builders Association of Delaware, shall establish programs to promote the construction of zero net energy homes. A zero net energy home or building is defined as a residence or commercial building that, through the use of energy efficient construction, lighting, appliances and on-site renewable energy generation, results in zero net energy consumption from the utility provider. Therefore, a zero net energy capable home must be energy efficient enough that if the home or building owner chooses to add on-site generation, net zero energy consumption could be achieved. By 2025, all new residential building construction in the State of Delaware must be zero net energy capable. By 2030, all new commercial building construction must also be zero net energy capable.

Washington State Energy Code
This act requires that residential and nonresidential construction permitted under the 2031 state energy code achieve a 70 percent reduction in annual net energy consumption, using the adopted 2006 Washington State energy code as a baseline. Furthermore, state energy codes shall be adopted until 2031 which incrementally move towards achieving the 70% reduction in annual net energy consumption.

Washington State Zero Energy Code Roadmap
The purpose of this roadmap is to provide context for the policy and code performance goals for new residential and commercial buildings in Washington law and identify the mechanisms and cycles by which code provisions can evolve to meet these goals. These code improvements will occur in incremental steps and this document will help identify the order and priority that is needed to lay the groundwork for subsequent code and policy strategies to improve code language. The improvements can be mapped into the planned code cycles remaining between now and the target achievement date for Washington’s policy goals for building stock. The Roadmap will also identify scope and policy barriers as well as opportunities that will need to be addressed to achieve the long‐term goals identified.

City of Boulder Commercial Energy Code
Under Boulder’s Energy Conservation Code, commercial buildings must achieve energy performance significantly exceeding national code baselines. Permit applications for commercial buildings larger than 20,000 square feet must utilize predictive computer modeling to demonstrate energy performance that is at least 30% better than ASHRAE/IENSA Standard 90.1. Permit applications for commercial buildings of 20,000 square feet or less may demonstrate energy code compliance by predictive modeling, but are also allowed to utilize approved prescriptive standards that achieve energy performance of at least 30% better than the 2012 edition of the IECC.

Pima County Net-Zero Energy Building Standard
The purpose of this standard is to provide both prescriptive and performance paths for designing net-zero energy buildings and net-zero energy remodels within the Tucson/Pima County climate. The prescriptive path is comprised of a series of high performance energy efficiency improvements that each building must incorporate.

San Antonio adoption of 2015 IECC
In 2015 the San Antonio City Council voted to adopt the 2015 International Codes, including the International Energy Conservation Code (IECC) for residential and commercial buildings. San Antonio is the first city in Texas to adopt the 2015 International Codes. This represents a milestone in the City’s efforts to improve the efficiency of new buildings and reduce energy costs for homeowners and businesses. Analysis shows that new homes will be 18% more energy efficient and commercial buildings will be 26% more efficient than those built to current code (IECC 2009).

Santa Monica Residential Energy Reach Code and ZNE
In 2016, Santa Monica City Council adopted the newly proposed Santa Monica Reach Code. The Santa Monica Municipal Code was updated in 2017 to include the following Energy Code Updates: all new low-rise residential buildings shall be designed to use 15 percent less energy than the allowed energy budget established by the 2016 California Energy Code, and achieve an Energy Design Rating of Zero; and all new high-rise residential buildings, non-residential buildings, hotels and motels shall be designed to use ten percent less energy than the allowed energy budget established by the 2016 California Energy Code.
