ASHRAE Applauds the National
Definition of a Zero Emissions Building
ATLANTA-ASHRAE applauds the U.S. Department of
Energy's release of a standardized, verifiable basis for
defining a zero emissions building.
The National Definition of a Zero Emissions Building:
Part 1 Operating Emissions is a comprehensive guideline
aimed at providing a broadly accepted minimum
standard for what constitutes a zero emissions building.
By setting clear and measurable criteria, this definition
offers a harmonized approach guiding both public and
private entities in transitioning the building sector
toward zero greenhouse gas emissions. Three ASHRAE
standards are referenced in the document: ANSI/
ASHRAE/IES Standard 90.1-2022, Energy Standard for
Sites and Buildings Except Low-Rise Residential Buildings; ANSI/
ASHRAE/IES Standard 100-2024, Energy and Emissions
Building Performance Standard for Existing Buildings; and
ANSI/ASHRAE Standard 228-2023, Standard Method
of Evaluating Zero Net Energy and Zero Net Carbon Building
Performance.

AND RENÉ GONZÁLEZ, MEMBER ASHRAE
SANTIAGO-The Government Affairs Committee of
ASHRAE's Chile Chapter has contributed to the
development of the new Chilean ventilation
standard NCh 3308, which includes many
portions of ASHRAE Standard 62.1-2022,
Ventilation and Acceptable Indoor Air Quality. The
Chilean standard was published on May 31,
2024. This milestone represents significant
progress in improving indoor air quality and
energy efficiency in buildings nationwide.

emissions, outlines three fundamental criteria for
zero emissions buildings: highly energy efficient, free
of on-site emissions from energy use and powered solely
from clean energy.
To ensure compliance, the definition includes
detailed methods of measurement and verification. For
existing buildings, criteria such as Energy Star scores or
measured whole-building energy use intensity are used,
while new constructions must meet stringent energy
efficiency and clean energy standards.
While Part 1 of the definition focuses on operational
emissions, Part 2 will address embodied carbon and
refrigerant impacts. These elements are crucial in fully
transitioning the building sector to zero emissions.
The National Definition of a Zero Emissions Building
will be embedded in nearly every green building
certification, adopted by leading investors and used in
federal programs.

ASHRAE ISSUES CALL FOR PAPERS
FOR IEQ 2025 CONFERENCE
ATLANTA-ASHRAE is accepting papers for the IEQ 2025 Conference, co-organized
by ASHRAE and AIVC (Air Infiltration and Ventilation Centre), to be held September
24 - 26, 2025, in Montreal, Canada. The theme of the conference is " Rising to New
Challenges: Connecting IEQ to a Sustainable Future " and focuses on increasing
understanding of how occupants respond to various indoor environmental factors
while enhancing resilience in the face of a changing climate.
The conference steering committee seeks papers on the following topics:
* Performance Metrics: for all aspects of IEQ;
* Occupant Behavior: how behavior impacts IEQ and how IEQ impacts behavior
(psychological dimensions of IEQ);
* Smart Sensors, Data and Controls: sensor properties, data management,
cybersecurity, applications, commissioning and equivalence;
* Resilience and IEQ: responding to climate change and disasters;
* Ventilation: mechanical, passive, natural and hybrid systems;
* Airtightness: trends, methods and impacts;
* Thermal Comfort: dynamic approaches, health impacts and trends;
* Policy and Standards: trends, impacts, implications;
* HVAC and IEQ in a Post-COVID World; and
* Ventilation and Building Decarbonization
