energy efficiency and reduced fuel
consumption shows how militaries
are adapting to intensifying natural
disasters and other challenges.
AHRTI Begins New Project to Assess
Refrigerant Detector Characteristics
ARLINGTON, VA.-AHRI's research arm

recently launched a new research
project to assess refrigerant sensor
and refrigerant detector performance requirements for flammable
refrigerants for use with indoor
HVAC&R equipment, whether in
an occupied space or a machinery
room. Research project No. 9014, Assess Refrigerant Detector Characteristics for Use in HVACR Equipment,
is designed to help clarify the necessary refrigerant detector requirements and how to specify them.

New Chemical Formula Improves
Structure, Efficiency of Solar Cells
GOLDEN, COLO.-NREL researchers have

produced a tandem perovskite solar
cell that pushes the technology
closer to its maximum efficiency.
The new chemical formula boosts
efficiency and improves the structural and optoelectronic properties
of the solar cell.

Scientists at CERN Hunt for
Greener Gases for Particle Detectors
MEYRIN, SWITZERLAND -During a planned

shutdown of the world's largest particle accelerator, staff at the Large
Hadron Collider (LHC) will make
repairs and upgrade the accelerator.
Researchers at CERN (the European
Organization for Nuclear Research),
which operates the accelerator, are

also using the shutdown as an opportunity to improve the facility's
environmental footprint by plugging up leaks and, in some equipment, replacing the most pernicious
greenhouse gases with less problematic alternatives.
New Buildings in Los Angeles
To Be Zero-Emission by 2030
LOS ANGELES-Los Angeles' mayor re-

leased the city's Green New Deal,
which sets L.A. on course to be
carbon neutral by 2050. Released in
April, the deal includes targets such
as building a zero-carbon electricity grid to reach an accelerated goal
of 80% renewable energy supply by
2036 and toward 100% renewables
by 2045.

Changes in IAQ Caused By Corona Discharge Air Cleaner
With 18 patents granted and
14 more pending, Global Plasma
Solutions (GPS) is the leading manufacturer of needlepoint bipolar ionization (NPBI) systems designed for
indoor air purification. As a result
of the column entitled "Changes in
IAQ Caused by Corona Discharge Air
Cleaner," (December 2018) we have
received numerous phone calls,
emails and direct inquiries challenging the efficacy and viability of
NPBI technology for treating indoor
air. In short, the acolumn has had
the negative effect of incorrectly
associating GPS' NPBI technology
with all corona discharge and other
ionization products. The column
states "Corona discharge (sometimes labeled: ionizing, negative ion,
activated oxygen, mountain fresh
air, etc.) ..." The readers of ASHRAE

Journal, and the market in general,
deserve to be made aware that NPBI
does not produce ozone or other
listed contaminants, and that NPBI
technology should not be associated
with corona discharge.
NPBI is not a corona discharge
technology. It should not be categorized in this manner, nor should it
be associated with corona discharge
and its negative side-effects. On
the contrary, GPS' NPBI technology
has been certified by UL 867 and UL
2998 as an ozone free technology.
That is, ozone, aldehydes and ultrafine particles are not created by the
application of NPBI. GPS or NPBI
technology is rightfully not listed
on the CARB website of Potentially
Hazardous Ozone Generators Sold
as Air Purifiers (https://www.arb.
ca.gov/research/indoor/o3g-list.

htm). In fact, NPBI is used by many
cleanroom manufacturers to reduce
ultra-fine particles. NPBI is successfully used in hospitals, offices,
airports, schools, arenas, airplanes,
veterinary offices and vivariums,
to name a few applications. GPS
has many third party IAQ studies
proving that NPBI does not produce
undesirable by-products. On the
contrary, the studies show that the
use of NPBI technology in conjunction with the IAQ procedure produces exceptional air quality and
substantial energy savings.
