Infectious Disease Subcommittee - Guest presentation from Lisa Brosseau, Slides

Tip: The following section can be edited by the webmaster as needed. It does not have to be about Whitepapers. You can edit that to be anything. To add, delete or reposition sections of the accordion, use the concentric arrows button in the editing toolbar at the top. When typing or inserting text into an accordion and there is more than one paragraph, you MUST use "shift + enter" between paragraphs. Be sure that you do not accidentally just use the "enter" key to separate the paragraphs. It will look OK but after you publish the page, the text after the 'enter' may no longer be editable.

Designing and Operating High-Performing Healthcare HVAC Systems (code 63)
3:30 p.m. – 6:30 p.m., JW Marriott - Indianapolis

This advanced course addresses the role of HVAC systems in helping to reduce Hospital-Associated Infections (HAI). What is airborne v. contact transmission? Through filtration, air patterns, air changes, dilution, temperature, humidity, UV, and pressurization the hospital HVAC can either help or hinder efforts to reduce HAI. This course describes the why and how of each of these processes from the perspective of particle physics. Instructor provides unabashed analyses of the controversies regarding the science behind the requirements in ASHRAE Std-170, such as: how many air changes, what level of filtration, etc. The class will cover the production and fate of airborne microorganisms and how people can get infected. HVAC design of airborne infectious isolation rooms, protective isolation rooms, operating rooms, emergency depts, sterile processing dept, infection control risk assessment.

Interested in prepping for the Healthcare Facilities Design Professional (HFDP) certification exam? See a complete list of HFDP exam task content areas this course addresses. (Note: green highlight = well addressed; yellow highlight = somewhat addressed).

Instructor: Don Burroughs, P.E., Member ASHRAE


NEW! Understanding ASHRAE Standard 241 Control of Infectious Aerosols – Background, Overview, and Key Requirements (code 67)
9:00 a.m. – 12:00 p.m., JW Marriott - Indianapolis

ASHRAE Standard 241 sets requirements for reducing the risk of airborne disease transmission indoors. This course provides background on airborne transmission and airborne infection risk mitigation and gives a comprehensive introduction to Standard 241. Key definitions and requirements for compliance, including equivalent clean airflow rates and air cleaner effectiveness and safety testing, are discussed in detail, and illustrated with examples. Assessment, planning, and operation and maintenance are summarized. Application of Standard 241 is covered by the companion course Is Your Building Ready? Applying ASHRAE Standard 241 Control of Infectious Aerosols – Facility Assessment, Planning, and Implementation.

Instructors: William Bahnfleth, Ph.D., P.E., Fellow/Presidential Member ASHRAE; and Marwa Zaatari, Ph.D., Member ASHRAE

Humidity Control Events in Perioperative Care Areas
Developed by: ASHRAE Technical Committee 9.6, Healthcare Facilities

This white paper provides a protocol for perioperative care areas when mechanical systems are unable to maintain relative humidity (RH) within the desired range that has been established by the facility for their specific operations. For the purpose of this paper, a humidity control event occurs when the RH is above or below the established facility RH range.

The White Paper may be downloaded for HERE free or a hard copy maybe purchased through the ASHRAE on-line bookstore.

HVAC Design Manual for Hospitals and Clinics, Second Edition
Principal Editor: Koenigshofer

The second edition of HVAC Design Manual for Hospitals and Clinics adds updated information, provides in-depth recommendations based on best practices, and presents proven, cost-effective and reliable solutions that result in low maintenance costs and high reliability. The intent for the the second edition of the manual is to focus specifically on heating, ventilating and air-conditioning (HVAC) system design for health care facilities, omitting general system descriptions that are readily available in other ASHRAE publications. Instead, our focus has been to present "what's different" about health care HVAC. 

The Design Manual may be purchased through the ASHRAE on-line bookstore.

Advanced Energy Design Guide for Small Hospitals and Healthcare Facilities: 30% Energy Savings
Principal Editor: Pless

Sixth in a series that provides recommendations for achieving 30% energy savings over minimum requirements of ANSI/ASHRAE/IESNA Standard 90.1-1999 for small hospitals and healthcare facilities. Helps achieve advanced energy savings without detailed calculations or analyses. Includes recommendations for all 8 U.S. climate zones.

The PDF version of the 30% Energy Savings Design Guide may be accessed for free download through the highlighted text.

Advanced Energy Design Guide for Large Hospital: 50% Energy Savings
Principal Editor: Pless

Advanced Energy Design Guide for Large Hospitals is the fourth in a series designed to provide recommendations for achieving 50% energy savings over the minimum code requirements of ANSI/ASHRAE/IESNA Standard 90.1-2004. The energy savings target of 50% is the next step toward achieving a net zero energy building, which is defined as a building that, on an annual basis, draws from outside resources equal or less energy than it provides using on-site renewable energy sources.

This Guide was created for a "standard" mid- to large-size hospital, typically at least 100,000 ft2 in size, but the strategies apply to all sizes and classifications of large hospitals. Space types covered include cafeterias and kitchens; conference and office areas; reception and waiting areas; examination and treatment rooms; clean and soiled workrooms; nurse stations; nurseries and patient rooms; operating, procedure and recovery rooms; sterilizer equipment areas; pharmacies and laboratories; triage, trauma, and emergency rooms; physical therapy and radiology/imaging rooms; storage, receiving, and mechanical/electrical/telecom rooms. This Guide does not directly address other, atypical or special-use spaces.
