RESEARCH REPORT

to provide fact-based guidelines for the maximum size of smoke reservoirs for such
buildings before dangerous conditions occur that are not predicted by current tools.
It is also impossible to provide guidance for the design of cost-effective and energy
efficient smoke control systems for such spaces. Without better information, building designs that include long atria may unknowingly expose the public to hazardous
conditions during a fire, which will result in liability issues for the designers of the
HVAC and Life Safety systems.

IAQ and Energy Implications of High Efficiency
Filters in Residential Buildings

April 2016 - August 2020 (P); University of Toronto; Principal Investigator, Jeffrey Siegel; TC
2.4, Particulate Air Contaminants and Gas Contaminant Removal Equipment

Filters are usually present in well-maintained forced air systems in the U.S., including
in residential systems with recirculation airstreams. The intent of this research is to
quantify the actual impact that high efficiency filters have on in-home PM concentrations, and it will result in a database of simultaneous measurements of indoor/outdoor
aerosol concentrations, system operational values e.g. run times, pressure drops), and
system energy use. This work will directly inform existing ASHRAE Standards including
minimum filtration aspects of 62.2-2007, which has been incorporated into existing
state energy codes e.g., for California), and the discharge addendum in 52.2-2007.
Finally, this work will provide data to better inform the residential consumer on: 1) IAQ
impacts of high efficiency purchases, which were estimated as an annual revenue
stream of $150 million to the filter market; 2) how often higher efficiency filters
both standard and electrostatic) should be changed to maintain their effectiveness
of PM concentration reduction; and 3) any associated energy costs with using higher
efficiency filtration.

Training Requirements for Sustainable, High
Performance Building Operations

November 2016 - September 2019 (P), Montana State University, Principal Investigator, Jaya
Mukhopadhyay; TC. 7.3, Operation and Maintenance Management, co-sponsored by: TC 7.6, Building Energy Performance, TC 7.8, Owning and Operating Costs and TC 2.8, Building Environmental
Impacts and Sustainability

Support of operating engineers and operations is critical to realizing ASHRAE's core
mission of creating better building environments. If we stop at design, we fall short
of fulfilling the potential of our knowledge. ASHRAE has a great deal of credibility to
gain by taking on responsibility for achieving high performance buildings across their
full life-cycle. In doing so, ASHRAE stands to gain strength and prominence as a
source of fundamental knowledge in alliances with major national organizations such
as USGBC, BOMA, IFMA, NIBS and agencies such as US DOE, NIST, FEMP, GSA and
state level energy agencies.

Coming Soon: How Air
Quality Affects Passengers on
Commercial Airplanes
The goal of 1262-RP, Relate Air Quality and Other Factors to Comfort
and Health Related Symptoms Reported by Passengers and Crew on
Commercial Transport Aircraft (Part 2), is to relate perception of discomfort or health-related symptoms of flight attendants and passengers
to possible causal factors. Those factors include cabin and bleed air
quality and other factors such as reduced air pressure, jet lag, inactivity,
humidity, flight attendant duty schedule and fatigue, circadian rhythm,
stress and noise.
The research project measured and characterized contaminants in
cabin air in a variety of airplane types and contaminants in cabin air that
are not introduced via ECS. The research quantified the effect of aircraft
type, maintenance, APU, engine age and operations-related parameters
on cabin and bleed air quality and investigated the relationship of the
measured cabin air contaminants, ventilation rates and other factors
with reported symptoms among passengers and flight crew.

close interaction among experts in energy modeling (TC 4.7), controls (TC 1.4) and
smart building systems (TC 7.5) using dynamic modeling of energy transports, control
systems and smart control algorithms.

Experimental Evaluation of the Thermal and
Ventilation Performance of Stratified Air Distribution
Systems Coupled with Passive Beams

April 2016 - August 2019 (P); Purdue University; Principal Investigator, Qingyan Chen; TC 5.3,
Room Air Distribution

The experimental results and recommendations will produce previously unavailable new design and operating guidelines for the combined system of displacement
ventilation with passive beams. The improved understanding achieved from this project
will allow this promising integrated technology to be considered more confidently by
system designers. This will reinforce the value of ASHRAE guidelines to building system
designers and help to ensure mechanical system design and installation provides
comfort while supporting ASHRAE's net-zero energy design strategies.

Guidance for CFD Modeling of Data Centers

August 1, 2017 to April 2020 (P); University of Colorado, Principal Investigator, Wangda Zuo, TC

Lin; TC 4.10, Indoor Environmental Modeling; co-sponsored by: TC 9.9, Mission Critical Facilities,
Data Centers, Technology Spaces and Electronic Equipment

This project will evaluate the performance of current control sequences for water
side economizers published in ASHRAE publications and recommend a new nearoptimal control sequence. It will also provide validated dynamic models to ASHRAE
and will demonstrate their use for control sequence evaluation. The project allows the

The primary objective of this research project is to provide CFD modeling guidance
for data center applications. The guidance will be based on experimental and CFD
analyses of several data center configurations to be conducted as part of this study
as well as other work available in the literature.
