Efficiency delivered.NBI is responding to increasing urgency to reduce carbon emissions and increased demand for improved energy performance of new and existing buildings.

NBI’s Theory of Market Change:

Our Program Areas

(1) Building & Program Innovation

(2) Zero Energy Leadership & Market Development

(3) Advancing Codes & Policy

Foundations of Building Decarbonization

Each of the three NBI program areas bring research, resources, and solutions to support the foundations of zero carbon building policies and to advance our mission.


Principles to Electrify

• Efficiency First

• Value of Flexible Load for Grid

• Understand Emissions Impact

• Use Emissions Efficiency

• Account for Life of Measure

• Rate Design

Policy Pathway or ActionNew Construction, Retrofit, or Both

Who Enables?Who Implements/

Enforces?

Improved Base Code + All‐Electric Voluntary Code

New Construction, Major Retrofits

IECC, IBC, ASHRAE, etc.

State Government Local Government, Permitting Officials, Developers, Builders, Contractors, Utilities

Improved Appliance Standards and Clean Air Standards

Both President DOE/EPA

Manufacturers, UL, Contractors, Utilities, Regulators

“Lead by example” Zero Emission Building Policy for Government Facilities

New Construction, Major Retrofits

President GSA, contractors

All‐Electric Incentive Program Both Congress, President

IRS; DOE and EPA

Grants and TA for Contractor Training/Education

Both DOE, EPA State Energy Offices, Universities, Trade Schools, Educational NGOs

Policy Pathways: State

Policy/Action New Construction, Retrofit, or Both

Who Enables? Who Implements/Enforces?

Building decarbonization target for new construction

New construction State Legislature, Governor

Building and Real Estate Industry, Utilities?, Regulators, Code Officials, Local Permitting Entities

All‐Electric Incentive Programs Both State Legislature, Governor

State Energy Office, Utility Regulators? Utilities?

Enable fuel‐switching programs and empower more ambitious local actions

Both State Legislature, Governor


Direct PUC and utilities to evaluate electrification, fossil fuel phase‐out as part of planning



Impose “feebate” on fossil fuel appliances and use funds to fund electric appliance programs


State Energy Office

Create a Revolving Fund to Finance Building Retrofits

Retrofits State Legislature, Governor

Process required by cities and counties to advance electrification policies

▸ Sustainability plan▸ Building and sustainability departments▸ Support of council/commission▸ Extensive outreach to building industry▸ Architects, engineers, homebuilders,

building owners, developers, apartment industry, trades and mfrs

▸ Timeline, roadmap, to reach goals▸ Ongoing collaboration for built environment

• Partnership with NRDC

• Includes three major pieces: • Code Overlay• Advocacy

Framework• Outreach

Toolkit

The Toolkit


Why an Overlay?

• 2021 IECC provides a solid efficiency foundation to build on

• Most states use the IECC already

• States and cities are familiar with the ICC and amendment process

• Language will be ready for introduction to future model code development cycles

31

32

17


Overlay Structure

• Focuses on new construction

• Includes residential and commercial

• Includes two “steps” for jurisdictions: • Mixed-fuel electric ready buildings• All-electric buildings

• Adds key enforcement language and removes vestigial language when necessary

• Most amendments in electric power sections


Example / Change in Language

• Full strike out and underline mark up, ready for adoption with the 2021 IECC

C101.3/R101.3 Intent. This code shall regulate the design, and construction of buildings for the effective use and conservationreduction of greenhouse gas emissions and for the efficient production, use and storage of energy over the useful life of each building. This code is intended to provide flexibility to permit the use of innovative approaches and techniques to achieve this objective. This code is not intended to abridge safety, health or environmental requirements contained in other applicable codes or ordinances.

Electric-Readiness • Electric infrastructure required for:

• Requirements for:• Branch circuits and labeling• Physical space and other associated needs (i.e.

condensate drains)

• Water heating• Space heating• Clothes drying

• Cooking• “Other”


Electric-Ready Water HeatingC405.16.2 Combustion water heating equipment. Gas-fired water heaters with a capacity less than 300,000 Btu/h (88 kW) shall be installed in accordance with the following:

1. A dedicated 208/240-volt branch circuit with a minimum capacity of 30 amps shall terminate within 3 feet (914 mm) …

2. A condensate drain that is no more than 2 inches (51 mm) higher than the base of the installed water heater …

3. The water heater shall be installed in a space with minimum dimensions of 3 feet (914 mm) by 3 feet (914 mm) by 7 feet (2134 mm) high, and

4. The water heater shall be installed in a space with a minimum volume of 700 cubic feet (20,000 L)

Demand Response

• Requires demand responsive thermostats

• Requires demand responsive water heating in accordance with ANSI/CTA-2045-B


On-site Solar Generation

• Residential: incorporates Appendix RB into main body of text• Requires solar ready zone and infrastructure• Redirects multifamily (3+ units) to commercial requirement

• Commercial: incorporates language from 90.1-2022 for mandatory on-site solar• 0.25W/ft2 * gross area of three largest floors• Requires documentation of RECS retained or retired

On-site Solar• R404.4.1.1 Solar-ready zone area. The total solar-ready zone area

shall be not less than 300 square feet (28 m2) exclusive of mandatory access or set back areas as required by the International Fire Code. Townhouses three stories or less in height above grade plane and with a total floor area less than or equal to 2,000 square feet (186 m2) per dwelling shall have a solar-ready zone area of not less than 150 square feet (14 m2)…

• C405.13 On site renewable energy. Each building site shall have equipment for on-site renewable energy with a rated capacity of not less than 0.25 W/ft² (2.7 W/m²) multiplied by the sum of the gross conditioned floor area of the three largest floors.


Energy Storage Ready

• Commercial Only: incorporates language from Appendix CB into main body of text• Requires dedicated space for energy storage• Requires reserved space on main electrical

panel

Electric Vehicles

• Residential: One- and two-family dwellings• Requires one EV-ready space/dwelling unit• Requires minimum capacity of 9.6kVA for charging• Redirects multifamily to commercial requirement

• Commercial: incorporates language from 90.1-2022 for mandatory on-site solar• EVSE, EV-ready, EV-capable required by occupancy type• Allows trading up to meet required percentages• Allows ALMS installation to reduce total capacity
