Reporting the Energy Use and Heat Gain from
Imaging Equipment

TC 9.6, Healthcare Facilities; co-sponsored by: TC 4.1, Load Calculation Data and Procedures
and TC 4.7, Energy Calculations - Pending Award

This research will be a valuable addition as it will provide a "more extensive database
for heat gains to air and water for imaging systems" by building upon both RP-1343
and Standard 203-2014. Once complete, Table 6 "Recommended Heat Gain from
Typical Medical Equipment" in Chapter 18 of the ASHRAE Fundamentals Handbook,
Table 4 "Summary of Heat Gain to Air from Imaging Systems" in Chapter 8 of ASHRAE
Applications Handbook, and Chapter 8 Section 4 "Imaging Rooms" of the HVAC Design
Manual for Hospitals and Clinics can all be updated. Further, the individual equipment
test and reporting protocol could evolve into consideration for adoption into an ASHRAE
Standard. Without this research, the existing tables and ASHRAE resources remain
incomplete and become less valuable because they are unable to provide sufficient
guidance to designers, and energy modelers.

Long-term Temperature Change of Ground Heat
Exchangers

TC 6.8, Geothermal Heat Pump and Energy Recovery Applications

Ground source heat pumps have emerged as one of the most efficient ways to heat
and cool buildings. This technical research will create information that will allow for
more accurate sizing of these systems. Designers will be able to refine their design
approach because they will have a better understanding of how to compensate for
long-term ground temperature change. Status: Conditionally Approved. Clear conditions

Accounting for the Barometric Pressure Impacts
on Psychrometric Performance Testing of Unitary
Air-Conditioning and Heat Pump Equipment

TC 8.11, Unitary and Room Air Conditioners and Heat Pumps; co-sponsored by: SSPC 41,
Standard Methods of Measurement

The major beneficiaries of this research include ASHRAE, DOE, AHRI, CEC, EPA,
equipment OEMs, and rating laboratories. 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 to ensure results are comparable
to test facilities at other altitudes. Status: Conditionally Approved. Clear conditions with

a significant hurdle for widespread adoption. The requested research will provide the
missing information that allows us to know if ultra-fine particle sensing is a viable
option for meeting this requirement in the standard. Status: Conditionally Approved.

Technologies and ASHRAE 145.2 Test Standard

TC 2.3, Building Energy Performance; co-sponsored by: SSPC 62.1 and SSPC 145

For this research project, EACs are defined as any air cleaning technologies with
gas-phase filtration capabilities derived from the use of an electrical component such
as, but not limited to, UV, UV-PCO, plasmas, and ozone generators. - Pending Award

Develop Performance Metric, Criteria, and Process
To Measure and Predict Speech Privacy in High
Performance Buildings

TC 2.6, Sound and Vibration Control; co-sponsored by: TC 4.4, Building Materials and Building
Envelope Performance

With the ASHRAE focus on the complete built environment and the comprehensive
updates to the acoustical control section of standard 189.1 for High Performance Buildings, the ASHRAE organization is positioned to be a lead proponent and standard bearer
for Indoor Environmental Quality (IEQ). The indoor environment and users experience
are interwoven with the acoustical performance, which is a factor of user's interactions
with the space and each other. Status: Conditionally Approved. Clear conditions with

Optimizing Supply Air Temperature Control for
Dedicated Outdoor Air Systems

TC 1.4, Control Theory and Application

The ASHRAE Advanced Energy Design Guides Series (ASHRAE.) has recommended
DOASs as part of the HVAC design strategy for most climate zones and building types
evaluated, including K-12 schools, hospital and healthcare facilities, small to medium
offices buildings, retail buildings, etc. This project will recommend new near-optimal
control sequences for DOAS systems and improve ASHRAE's Advanced Energy Design
Guides Series. The control sequences generated from the research will be submitted to
ASHRAE Guideline Project Committee 36 "High Performance Sequences of Operation
for HVAC Systems". The results of the project can also improve the recently published
ASHRAE Design Guide for Dedicated Outdoor Air Systems (ASHRAE, 2017). Status:
Conditionally Approved. Clear conditions with Research Liaison so project can bid.

Experimental Characterization of Aircraft Bleed
Air Particulate Contamination

TC 9.3, Transportation Air-Conditioning; co-sponsored by: SSPC 161, Air Quality within
Commercial Aircraft

ASHRAE Standard 161 was designated as a policy level standard by ASHRAE and
its development demonstrates ASHRAE's international leadership in aircraft cabin air
quality, an area of increasing national and international interest. The requirement for
bleed air contaminant monitoring is an important provision of the standard and played
a major role in bringing divergent interests to a consensus that allowed the standard
to be broadly supported. The lack of a viable option to implement a key provision is

Information is needed to ensure short- and long-term reliability of air-conditioning
and refrigeration equipment using LGWP refrigerants and synthetic lubricants. Foaming in refrigerant systems can lead to lower efficiency or even system inoperability or
failure, and there have been no studies published to date on foaming with lower GWP
refrigerants compared to existing refrigerant/ lubricant pairs. Oil chemistries in use
today are not expected to change significantly as refrigerant chemistries are changed;
thus, it is necessary to understand the magnitude of any system foaming differences
with lower GWP refrigerants. Status: Conditionally Approved. Clear conditions with
