space. Knowledge of the dynamic interaction of radiant systems with various heat
sources will produce guidelines for modeling space conditioning systems that involve
radiation heat transfer, which include radiant and stratified systems UFAD and displacement ventilation) that will create non-uniform surface temperatures in the space. The
results and improved modeling methods from this project could also be used in future
efforts to update the Radiant Time Series method for radiant cooling applications or
the weighting factor method for energy performance modeling.

Develop Design Criteria for Psychrometric Air
Sampler and Mixer Apparatus for Use in ASHRAE
Test Standards

August 2018 - March 2020; Oklahoma State University; Principal Investigator: Christian Bach;
TC 8.11, Unitary and Room Air Conditioners and Heat Pumps

This research will improve the consistency between the manufacturer and audit
test facilities, which will result in less risk and improved verification of compliance
standards. This project will provide technical detail to HVAC testing laboratories that
test unitary systems where the air must be sampled for both dry bulb temperature
and humidity. This sampling impacts all users of psychrometric test facilities from
the development of performance ratings to the verification of compliance with
energy efficiency standards.

Reproducing a Representative Urban Atmospheric
Aerosol Distribution at High Concentration in
the Laboratory for Air Filter Ageing to be used
in ASHRAE GPC 35P for Determining the Energy
Consumption Caused by Air Filters

August 2017 - July 2020; Purdue University, Principal Investigator: Brandon Boor; TC 2.4,
Particulate Air Contaminants and Particulate Contaminant Removal Equipment, Co-sponsored by:
SSPC 52. Method of Testing General Ventilation Air Cleaning Devices for Removal Efficiency by
Particle Size

The results from this work statement would affect the energy usage and design
criteria for several ASHRAE Handbook Chapters and Standards. The Handbook chapters
that would be affected are Chapter 29 - Air Cleaners for Particulate Contaminants,
HVAC Systems and Equipment Handbook; and Chapter 46 - Control of Gaseous Indoor
Air Contaminants, Applications Handbook.

Understanding Fan Coil Components and How
They Relate To Energy Consumption and Energy
Modeling

January 2017 - December 2019; University Louisiana Lafayette; Principal Investigator, Peng
Yu TC 5.3, Room Air Distribution, Co-sponsored by: TC 4.7, Energy Calculations & TC 7.7, Test &
Balance

The experimental results and recommendations will result in previously unavailable part load capacity and efficiencies maps for fan coil systems. The new tools
and modeling options developed will improve the ability of design engineers to
evaluate and predict the energy and comfort performance of buildings using fan coil
systems. The better understanding of efficiencies at part load operations achieved
from this project will allow more confident applications by system designers. This
will reinforce the value of ASHRAE guidelines to building systems, and support
ASHRAE's net-zero energy design strategies. This research will be of great value
to the Engineering community and provide more pertinent and accurate information in the selection of fan coils for any given application. In obtaining the accurate

information needed for fan coil selection, sizing issues will decrease and reduce
overall energy consumption significantly.

Effect of Inlet Duct and Damper Design on ASHRAE
37/116 Fan Performance and Static Pressure
Measurements

August 2017 - February 2020 (P); Oklahoma State University, Principal Investigator; Christian
Bach, TC 8.11, Unitary and Room Air Conditioners and Heat Pumps

The major benefit of this project is to provide technical clarification to HVAC
testing laboratories when testing samples. This subject impacts all users of unitary
air-conditioning equipment such as DOE, California Energy Commission, independent
test facilities and manufacturers of unitary equipment. Standardization will provide
more consistent setups and repeatability between manufacturer's laboratories and
3rd party certification laboratories.

Impact of Gaseous Contamination and High
Humidity On the Reliable Operation of Information
Technology Equipment in Data Centers

July 2016 - February 2020 (P); Syracuse University; Principal Investigator, Jianshun Zhang;
TC 9.9, Mission Critical Facilities, Data Centers, Technology Spaces and Electronic Equipment; Cosponsored by: TC 2.3, Gaseous Air Contaminants and Gas Contaminants Removal Equipment

The project will address the impact that gaseous contamination has when adopting the expanded thermal guidelines for data processing equipment. Specifically, it
will look at the impact that the expanded acceptable humidity envelope has on IT
equipment reliability when subject to environments that have higher than normal
concentrations of gaseous contaminants.

Evaluation of Particle Sensors for Indoor Air Quality
Monitoring and Smart Building Systems

September 2017 - March 2020 (P); Ohio State University; Principal Investigator, Andrew May;
TC 2.4, Plant and Animal Environment, Co-sponsor: TC 7.5, Smart Building Systems

The objectives of this proposed research are to fully test and document the
performance of a large number of commercially available PM sensors and to provide
recommendations for developing ASHRAE standards and guidelines for evaluating
their performance for applications in IAQ monitoring and integration into smart
building systems.

Impact of Air-Flow on Thermal Performance of AirSpaces Behind Cladding Phase 1 of 2)

September 2018 - February 2020; Swiss Federal Institute of Technology; Principal Investigator:
Dolaana Khovalyg; TC 4.4, Building Materials and Building Envelope Performance

The objective of this project is to quantify the effect of and establish testing
and design recommendations to account for the impact of air exchange rates or
ventilation air flow) on the thermal resistance of vertical air spaces behind selected
cladding systems that are exterior to the air barrier. It is envisioned that the air space
behind the selected claddings will include assemblies with and without at least one
surface that is perpendicular to the primary direction of heat flow with an initial
total hemispherical emittance less than 0.10. Air exchange rates or ventilation flows
into and out of the airspace and the impact on thermal resistance will be assessed
and used in testing and analysis of thermal performance. Results will be used to
recommend changes and additions to applicable test standard s), the ASHRAE
Handbook of Fundamentals [9], and ASHRAE Standard 90.1.
