& TC 7.6, Building Energy Performance
The objective of this RP is to assess the representation of building occupant behavior in Building
Information Modeling (BIM) and Building Energy Modeling (BEM) workfl ows and develop proposals
for implementation and adoption of data schema enhancements to leading open standards bodies
(i.e. - gbXML, IFC).

November 2019 - June 2022 (P); Mazzetti; Principal Investigator, Walt Vernon;
TC 9.6, Healthcare Facilities; co-sponsors: TC 4.1 Load Calculation Data and
Procedures & TC 4.7 Energy Calculations
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 suffi cient guidance to
designers and energy modelers.
 1824-RP Accounting for the Barometric Pressure Impacts on
Psychrometric Performance Testing of Unitary Air-Conditioning and
Heat Pump Equipment
April 2020 - July 2024 (P); University of Louisiana at Lafayette; Principal
Investigator: Peng " Solomon " Yin; TC 8.11 (Unitary and Room Air Conditioners
and Heat Pumps)
The goal of this project is to develop a set of guidelines for testing unitary air conditioners and
air-source heat pumps at different barometric pressures and a correction procedure to adjust
the measured results to standard conditions. Three aspects need to be considered: the effect
of barometric pressure on outdoor air mass fl ow rate, the standard condition " corrected " indoor
coil airfl ow rate impact on fan power and appropriate psychrometric conditions independent
of barometric pressure. The major benefi ciaries 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
verifi cation 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.

Frost Load on a Test Evaporator in a Test Chamber with an Operating
Conditioning System,
September 1, 2021 - March 1, 2024 (P); Creative Thermal Solutions; Principal
Investigator: Stefan Elbel; TC 10.7 Commercial Food and Beverage Refrigeration
Equipment.
Examine at least three approaches that can be used for indicating the magnitude of a frost load
accumulated on a unit cooler and that can be also used as part of a walk-in refrigeration system
testing in current test chambers designed for performance measurement in accordance with AHRI
1250-2014. The potential approaches will be the primary methods for indicating that a full frost
load has accumulated on the unit. The test plan for the research involves the usage of a secondary
box to allow direct measurement of the injected moisture for the verifi cation of the viability of
the primary methods. The objective is to determine which primary method provides the most
repeatable indication that a full frost load has accumulated, without requiring a direct measurement
of the frost mass, or of the frost volume with the dedicated secondary box.

Animal Facilities and Health Care Facilities with Medium to High ACR
September 2019 - April 2021 (P); Affi liated Engineers; Principal Investigator:
Roger Lautz; MTG.ACR (Air Change Rates)
This project will foster and engage ASHRAE relationships with other organization memberships
and in turn strengthen member value proposition. This project creates a learning endeavor that
could be emulated to additional standards or activities within ASHRAE and outside of ASHRAE and
to help promote ASHRAE as a leader in ventilation guidance.

April 2023 - August 2024; Ohio State University; Principal Investigator:
Jordan Clark; TC 9.10, Laboratory Systems; co-sponsors: TC 4.3, (Ventilation
Requirements and Infi ltration); TC 5.1 (Fans)
The scope of work for characterizing the plume performance from induced fl ow stacks comprises
of two types of tests. The fi rst test is designed to characterize the shape of the velocity profi le just
below the top of the wind band. The second test involves measuring the plume height and lateral
and vertical spread of the plume downwind of the stack and comparing these results to a fully
developed exhaust fl ow stack operating in the same environment and to calculated values from the
ASHRAE dispersion model. All testing should take place in an open fi eld that is void of obstacles
that could infl uence of airfl ow characteristics within the measurement fi eld.

October 2019 - September 2023 (P); Technical University of Denmark; Principal
Investigator: Pawel Wargocki; Co-PI Li Lan; TC 2.1 Physiology and Human
Environment
The overall objective of the proposed work is to document the effects of poor ventilation in
sleeping environments and the consequences for healthy living and working. Specifi c objectives
include: measurement of the actual ventilation rate in bedrooms and comparison with the
requirements prescribed by the standards; examination of the effects of ventilation on the air quality
in sleeping environments and how this affects sleep, next-day well-being and next-day ability to
work; determination of the minimum outdoor air supply rate to eliminate negative effects of poor
bedroom IAQ on sleep quality; and revision of ventilation requirements in sleeping environments.

April 2023 - September 2024; Secat; Principal Investigator: David Herrin; TC
4.01 Load Calculation Data and Procedures; co-sponsored by: TC 4.02 Climatic
Information;
Climatic design conditions in Chapter 14 of the Handbook are essential for sizing and design
procedures for HVAC systems; they enable energy system capacity to be sized in such a way that
it meets climatic loads in a probabilistic sense. Regular updating of the climatic design conditions
has therefore a direct impact on the work of HVAC practitioners and shows due diligence in a world
of changing climate.
 1852-RP Develop Performance Metric, Criteria and Process to
Measure and Predict Speech Privacy in High Performance Buildings
April 2020 - November 2024 (P); Soft dB Acoustical Consulting; Principal
Investigator; Roderick Mackenzie; TC 2.06, Sound and Vibration Control; cosponsor;
TC 4.04, 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 is interwoven with the acoustical
performance, which is a factor of user's interactions with the space and each other. Through this
work the metric, measurement protocol and performance standard can be codifi ed within 189.1/
IgCC for adoption by authorities having jurisdiction (AHJ)s, other standards/certifi cations (WELL
Building, LEED, FitWel, etc.) and the international design community.

(k-values) for Microorganisms Critical to System Design
December 2022 - August 2024 (P); Icahn School of Medical Mount Sinai;

Treatment
The objectives of this study are as follows: Conduct a comprehensive literature review and
develop a database of UV rate constants (k values, including z values) for a selected list of
microbiological organisms responsible for airborne disease and health-care-acquired infections.
Develop a tabular k-value database summarizing the k values obtained from the literature and
classify them according to specifi ed criteria used for determining the rate constant. Make
recommendations for the k-values for the selected microorganisms and viruses that can be used
by design engineers and for inclusion in relevant ASHRAE publications. Identify knowledge gaps
and make recommendations for further investigation.
