## Background

                    President Biden called for net-zero emissions, economy-wide, by 2050 and a 100% clean energy electricity sector by 2035.[1]                                          The building sector currently contributes more than one-third of U.S. greenhouse gases. Within the building sector, the Biden-Harris Administration has set the goal to make zero emissions resilient new construction and retrofits common practice by 2030. Accomplishing these goals will require increasing efficiency and expanding clean energy capacity. Zero emissions buildings will plug into a grid that is rapidly becoming cleaner. All buildings, both new and existing, have a critical role to play in achieving a clean energy economy. A clean energy economy advances the goals of tackling the climate crisis, and protecting public health and the environment, including local communities' health and well-being. Executive Order 14096, “Revitalizing Our Nation's Commitment to Environmental Justice for All,” directs every Federal agency to advance environmental justice for all, including work to better protect communities with environmental justice concerns from the increasing impacts of climate change. It is also vital that the Administration is implementing Executive Order 14096 and the historic Justice40 Initiative, which set the goal that 40 percent of the overall benefits of certain Federal investments in climate and other key areas flow to disadvantaged communities.                

                    A broadly accepted common minimum definition for a zero emissions building, as well as a pathway for verification, is foundational to efforts by public and private entities to transition the building sector to zero emissions.[2]                                          The intent of Part 1 of the National Definition for a Zero Emissions Building is to create a standardized, consistent, measurable basis for zero operating emissions buildings. This clear market signal and consistent target is intended to help move the building sector to zero emissions. The definition may serve as a framework that users can achieve through multiple pathways to influence the design and operation of buildings to substantially reduce building sector emissions.                

The minimum criteria included to define a zero operating emissions building is a building that is:
    - Highly energy efficient,
    - Free of on-site emissions from energy use, and
    - Powered solely from clean energy.

Part 1 of the draft National Definition for a Zero Emissions Building focuses on operational emissions which have well-established measurement protocols. Reducing the whole life cycle emissions of a building also requires minimizing the embodied carbon of the building, as well as minimizing the impacts of refrigerants. Such emissions are not within scope for Part 1 and may be considered in subsequent parts to the National Definition for a Zero Emission Building.

This definition can be applied to existing buildings and new construction of non-federally owned buildings. This definition is not intended for federally owned buildings, which are governed as a portfolio through statutory and executive guidance.

                    Part 1 of the draft definition in full, which includes details on the criteria above, is available here:                     *https://www.energy.gov/​eere/​buildings/​national-definition-zero-emissions-building.*                     This RFI is intended to collect broader technical input on Part 1 of the draft definition. DOE will consider responses to this RFI before finalizing version 1.00 of Part 1 of the National Definition for a Zero Emissions Building.                

                    DOE issued a RFI in 2015 for zero energy buildings.[3]                                          While the 2015 RFI was informative, the National Definition for a Zero Emissions Building in this RFI has different parameters.                

## Purpose

The purpose of this RFI is to solicit feedback from industry, academia, research laboratories, government agencies, and other stakeholders on Part 1 of a draft National Definition for a Zero Emissions Building.

## Request for Information Questions

                    Please reference the linked full draft of Part 1 of the National Definition for a Zero Emissions Building when responding to these questions.                          ( print page 1088)    

A. Are the draft criteria clear and appropriate for the definition for a zero emissions building? Should any other criteria be considered for Part 1? Please provide specific feedback about this draft definition.

B. Energy efficiency criteria.

○ Should energy efficiency be considered a criteria for the definition of a zero emissions building?

○ If the efficiency of an existing building should be considered, do you agree that requiring energy performance in the top 25% of similar buildings is an appropriate measure of energy efficiency for this definition? (ENERGY STAR® score of 75 or above.) Should it be higher or lower?

 Are there other benchmarks or approaches that should be considered?

 For an existing building, is one year of measured energy performance an appropriate requirement for demonstrating efficiency or is another approach appropriate?

 Are the draft criteria appropriate for single-family homes? Are there other benchmarks that should be considered for single-family homes?

                    ○ For new construction, are the draft criteria appropriate? The modeled building performance is at least 10% lower than the energy use according to the latest version of IECC or ASHRAE 90.1 (                    *e.g.,*                     model energy code) and the building is designed to achieve an ENERGY STAR score of at least 90 (for eligible buildings). Are there other benchmarks that should be considered?                

 Are the draft criteria appropriate for single family homes? Are there other benchmarks that should be considered for single family homes?

C. On-site emissions from energy use.
    - Should there be an exemption allowed for emission producing emergency generation? Are any other exemptions needed?
    - Should biofuels consumed on-site be allowed? If so, how?

D. Clean energy generation and procurement.
    - Are the clean energy criteria provided appropriate for this definition? Are there other clean energy criteria that should be considered? Should community solar qualify for this requirement? If so, how?
    - Should there be a proximity requirement for off-site power used to meet the clean power criterion? If so, how should a proximity requirement be implemented ( e.g.,                      regional definition, phase-in, etc.)?                

E. Documentation is important for effective implementation.
    - Should organizations leveraging the definition be able to determine whether buildings have to meet it annually, one time, or on a different frequency?
    - If the definition is extended to single-family homes, what documentation should be required?
    - Are licensed professional and third-party certification bodies the appropriate parties to independently verify the documentation that a building has met the definition? Beyond existing government resources such as EPA's ENERGY STAR Portfolio Manager, are there other methods to verify meeting the zero emissions building definition?
    - What time frame should be used for greenhouse gas (GHG) calculations ( i.e.                      hourly, monthly by year, annually)? Explain how this would be implemented effectively across the market.                
    - What other verification criteria are necessary to make this definition useful for the marketplace?
    - Are there any issues regarding conflict or synergy with regional, state or local energy and climate programs that ought to be addressed?

F. Use cases.
    - Is it important for a national definition to cover all building types, including commercial, multifamily, and single-family?
    - Are there any other recommendations that would help clarify and improve the definition?
    - While Part 1 of the definition focuses on operating emissions, what other areas should be considered in future parts of the definition, such as embodied carbon, refrigerant, and grid interactivity?
