| ACEEE Pathways to Zero Energy Buildings through Building Codes | Visions/Plans | Link | ACEEE | This white paper examines the current state of zero energy codes and provides an update on avenues to achievingzero energy codes by 2030. It presents an overview of current efforts to achieve zero energy and similarly high-performing buildings, example code proposals that help move the needle toward ZEBs, and thoughts on additional issues and barriers. |
| Architecture 2030 ZERO Code | Advanced Codes, Standards and Programs | Link | Architecture 2030 | Buildings constructed to the Zero Energy Commercial Building Provisions will produce fewer carbon emissions than conventionally powered buildings that place an additional electric load on the grid. See also IECC 2021 Appendix CC. |
| ASHRAE 90.2 | Advanced Codes, Standards and Programs | Link | ASHRAE | This standard results in homes approximately 50% more efficient than the 2006 IECC baseline and is in line with net zero ready levels of efficiency. It uses a performance based HERS like program which is already familiar to many code officials and home raters. |
| ASHRAE ZE for small office Buildings | Design Guide | Link | ASHRAE | |
| ASHRAE ZE for small office Buildings | Design Guide | Link | ASHRAE | To promote building energy efficiency, ASHRAE and its partners are making the Advanced Energy Design Guides available for free download (PDF). The zero energy Guides offer designers and contractors the tools needed for achieving zero energy buildings. The 50% Guides offer designers and contractors the tools needed for achieving a 50% energy savings compared to buildings that meet the minimum requirements of Standard 90.1-2004, and the 30% Guides offer a 30% energy savings compared to buildings that meet the minimum energy requirements of Standard 90.1-1999. |
| Boulder Energy Code - 2020 | Visions/Plans | Link | City of Boulder | The City of Boulder has set a goal of reaching net zero energy (NZE) construction through building and energy codes by 2031 |
| British Columbia BC Energy Step Code | Advanced Codes, Standards and Programs | Link | Integral Group, others | Thermal energy demand intensity targets, Total EUI targets, air tightness targets, designed as a step code out to their goal of all new construction being zero carbon by 2032. They have also created a smart incentive program tied to the various steps in order to drive market transformation. |
| Building Tune-ups | Existing Buildings | Link | Seattle | Seattle has enacted a “Building Tune-Up Ordinance” that requires a thorough assessment of a building’s energy-consuming systems every five years, and correction of a list of deficiencies. Such rules ensure that existing buildings are operating close to their optimum |
| Cambridge Net Zero Action Plan | Visions/Plans | Link | City of Cambridge | Comprehensive plan to phase out GHGs from buildings, including net zero emissions standards for new buildings over time |
