A Healthier Built Environment for All
W
hat does it mean to truly decarbonize? In light of global energy crises
and the mounting effects of climate change on earth, the conversation
around decarbonization has only become more complex and far-reaching.
In this issue of ASHRAE Journal, Paul Torcellini, Ph.D., P.E., Fellow ASHRAE,
is interviewed on all things decarbonization in " Asked and Answered:
Decarbonizing the Built Environment, " on page 14. The discussion
encompasses practical advice and knowledge on decarbonization in the
HVAC industry.
And for those who can't get enough of " Asked and Answered, " listen
to Paul talk decarb on the Hot Air podcast this month. Also available
this month on ASHRAE Journal Podcast- " Residential Buildings: Energy
Efficiency, Decarbonization and Standard 90.2, " hosted by Rachel L.
Romero, P.E., Member ASHRAE, and featuring guests Theresa Weston,
Ph.D., Member ASHRAE, and Philip W. Fairey, Member ASHRAE, as they
discuss IEQ, energy efficiency, resiliency and other key aspects of the
residential space in HVAC.
Also in the news is the arrival of the first-ever pathogen mitigation
standard, ASHRAE Standard 241, Control of Infectious Aerosols. The new
standard will provide minimum requirements for HVAC-related measures
to reduce the risk of transmission of COVID-19, influenza, and other
airborne viruses in homes, offices and other buildings.
Public health and pathogen control is also featured in this issue of
ASHRAE Journal. In " Modeling SARS-CoV-2 Infection Risk in Various
Office Building HVAC Systems, " on page 52, infection risk in several
HVAC system layouts is assessed. Authored by Alberto Cavallini, Member
ASHRAE, Filippo Busato, Ph.D., Member ASHRAE, and Fabrizio Pregliasco,
the article is a robust technical evaluation of using air recirculation to
lower the infection risk of the SARS-CoV-2 virus in office buildings.
The quanta of infection (q), an abstract measure of the infectious
potential of an environment, is a metric explored further in this
month's IEQ column, on page 24, " Comparative Analysis of Quanta and
R-naught: Implications for Infectious Disease Dynamics and Control
Measures. " Columnist Linda D. Lee, Dr.Ph., Member ASHRAE, explains
the significance of both the quanta of infection and the basic reproduction
number (R-naught; R₀) in the field of infection disease research and the
relevance of pathogen disease modeling for protecting occupants against
future pandemics.
We hope you enjoy the issue! If you are interested in contributing to the
Journal, please reach out to editorial staff.
