REPORT
 1873-TRP-R Upper-Air Ultraviolet Germicidal Irradiation (UVGI)
for Tall Spaces
Responsible Committee: TC 2.09, Ultraviolet Air and Surface Treatment; cosponsor;
TC 9.06 Healthcare Facilities
Research is necessary to address issues precluding consensus design guidelines for upper-air
UVGI systems installed in tall spaces. Mphaphlele's (2015) volume-based approach to system
design is met with apprehension from some system designers due to perceived penalties on initial
equipment and energy costs when the strategy is applied to tall spaces. Under this room volume
design strategy, a given room requires a certain number of UV fi xtures to adequately dose the
space with UV energy.
 1895-TRP-C Effect of Penetration Through Particle Pre-Filters on
the Performance of Gas Filters

Contaminant Removal Equipment; co-sponsors: TC 2.4 Particulate Air
Contaminants and Particulate Contaminant Removal Equipment, GPC 35
Method for Determining the Energy Consumption Caused by Air-Cleaning and
Filtration Devices
The research will help users maximize the lifetime effectiveness of gas-phase fi lters by choosing
optimal pre-fi ltration to provide better air quality, lifetime estimates and energy savings. The
research would also provide a better determination of pressure drop in the gas fi lter during loading
of the pre-fi lter/gas-phase fi lter combination and assist in the choosing of the best particle prefi
lter for the system. The research will also illuminate whether the choice of a pre-fi lter has a large
or small impact on the performance of the gas-phase fi lter.
 1909-TRP In-Tube Condensing Flue Gas Heat Transfer and
Pressure Drop with Enhancements for Residential Furnaces
Responsible Committee: TC 1.03 Heat Transfer and Fluid Flow; co-sponsors; TC
6.03 Residential and Light Commercial Forced Air Heating and Cooling Systems
Improved modeling of HVAC&R systems is an important part of ASHRAE's mission. Furnaces in
some form will be a part of our built environment heating strategy for the near-term. In order to
minimize the energy usage/carbon footprint of these appliances, improved understanding of the
physics that takes place in their heat exchangers is necessary. Applying this improved modeling
understanding, coupled with addressing the application of hydrogenated fuels to residential
furnaces, will assist us in reaching our decarbonization goals.
 1910-TRP Evaluation of Standard 103 Transient Components and
Thermostat Cycle Times on the Resulting AFUE
Responsible Committee: TC 6.03 Residential and Light Commercial Forced Air
Heating and Cooling Systems
ASHRAE standards drive industry test practices and federal government labeling practices in
this area. The project will bring together the best experts in the fi eld in TC 6.03 and qualifi ed
researchers to reduce the complexity of the AFUE test procedure and to evaluate the interaction
of the equipment in this study and new electronic thermostats. The standard will be improved with
this new information and the research and manufacturing communities will have a peer-reviewed
dataset for making decisions on design improvements and expected performance levels.
 1913-TRP-C Study of the Corrosion Impact on Information
Technology Equipment in Data Centers Located in Coastal Regions
with High Sea Salt Concentration
Responsible Committee: TC 9.9 Mission Critical Facilities, Data Centers,
Technology Spaces and Electronic Equipment: co-sponsors; TC 2.03 Gaseous
Air Contaminants and Gas Contaminant Removal Equipment, TC 2.04 Particulate
Air Contaminates and Particulate Contaminant Removal Equipment
The results of this project will provide data that will be used to verify or modify the ASHRAE
Thermal Guidelines for Data Processing Equipment located in marine environments. These
guidelines are made available in the ASHRAE handbooks, special publications and standards.
Potential benefi ts of the project include: Justifi cation for the acceptable temperature, humidity,
salinity levels and wet/dry cycles for marine environments. Improved reliability of data center
information technology equipment including those that require a high level of resilience. Reduction
in dehumidifi cation energy use in data centers. Increased use of economizers to coincide with the
adoption of Standard 90.1 and 90.4 for data centers

ASHRAE JOURNAL ashrae.org O CTO B E R 2 0 2 4
Responsible Committee: TC 10.02 Refrigeration Applications
The principal impact will be on the refrigeration practitioners and those professionals and
personnel involved in the design, construction, operation and maintenance of refrigerated
facilities. The potential for adoption by industry is high, provided the results include a current and
comprehensive list of door protection devices and that the information is presented in a form that
is relatively easy to apply.
 1918-TRP-R The Verifi cation of Openings, the Limitations of
Openings, Air Distribution and Humidity Conditions in Naturally
Ventilated Spaces to Complement Section 6.4 of ASHRAE Standard
62.1
Responsible Committee: SSPC 62.1. There is presently a lack of information in
ASHRAE Handbooks and Standards.
The ASHRAE Natural Ventilation Design Guide is being prepared for publication. This design
guide uses the compliance required by ASHRAE Standard 62.1, section 6.4, of which the 2H and
5H dimensions are still limitations.
Project is divided into multiple tasks. Some of the tasks need to be performed in sequence, while
others may be performed in parallel. The task deliverables are spelled out in the next section. This
section describes the needed work. Some leeway has been given to allow potential PIs to bring their
expertise to the project. Many of the questions for the project, discussed below, will be reasonably
addressed in the proposal including likely sampling and analysis techniques. The expectation is
that the project will include the test plan development and not sampling or analysis technique
development that the PI should already be versed in.
 1925-TRP-C Development of View Clarity Metrics for Fenestration
Systems
Responsible Committee: TC 4.05 Fenestration
This project will develop the fi rst of its kind unifi ed view clarity metric, a novelty that will benefi t
fenestration design and control guidelines towards human-centered building design. Together with
energy and comfort-related metrics, this index will contribute to a more integrated assessment of
IEQ in perimeter building spaces, a priority for ASHRAE. Moreover, this research will strengthen
ASHRAE's position as a leader in assessing IEQ holistically and infl uence related national and
international standards and product rating schemes.
 1947-TRP Climate Change Driven Extreme Temperature Effects for
Effi ciency and Resilience Map of Heat Pump Technology
Responsible Committee: TC 2.05 Global Climate Change; co-sponsors: TC 4.2
Climatic Information; TC 2.8 Building Environmental Impacts and Sustainability
The emergence of anomalous, rapid climate change in the last couple of decades has made it
necessary for energy calculations to estimate uncertainty in HVAC&R performance due to weather
uncertainty. The warming trend observed along with rapid urbanization and population growth
indicate that HVAC&R could become a signifi cant positive feedback in the consequences of the
emerging climate crisis. Positive feedbacks strengthen an effect.
 1950-TRP-C Effect of Residential Exhaust Terminations on Jet
Mechanics and Resulting Required Intake Separation
Responsible Committee: TC 4.03 Ventilation Requirements & Infi ltration; cosponsors:
SSPC 62.1, Ventilation and Acceptable Indoor Air Quality
The goal of this project is to identify engineering solutions that could provide good IAQ while
reducing design constraints by identifying whether the minimum separation distance could be
reduced under certain design scenarios. This will also facilitate energy effi ciency measures such as
specifi cation of HRVs and other energy-effi cient ventilation strategies.
 1964-TRP Optimizing Heating System Performance in Warmup
and Setback Modes
Responsible Committee: TC 1.04 Control Theory and Application; co-sponsors:
TC 7.05 Smart Building Systems
The project is expected to develop simple control strategies that will improve heating
system effi ciency and performance and facilitate the industry shift to all-electric heating. The
resulting strategies will be simple modifi cations from current practice with negligible cost for
new construction and potentially minimal cost for retrofi ts. Where the new strategies allow for
smaller equipment sizing and avoid the need for replacing existing infrastructure in retrofi ts,
the new warmup strategies may reduce both fi rst costs and operating costs. These novel
warmup strategies are expected to align with ASHRAE's of reducing carbon emissions from the
commercial building sector. 
