ASHRAE Position Document onInfectious Aerosols

Download the document.

The pathogens that cause infectious diseases are spread from a primary host to secondary hosts via several different routes. Some diseases are known to spread by infectious aerosols; for other diseases, the route of transmission is uncertain. The risk of pathogen spread, andtherefore the number of people exposed, can be affected both positively and negatively by the airflow patterns in a space and by heating, ventilating, and air-conditioning (HVAC) and local exhaust ventilation (LEV) systems. ASHRAE is the global leader and foremost source of technical and educational information on the design, installation, operation, and maintenance of these systems. Although the principles discussed in this position document apply primarily tobuildings, they may also be applicable to other occupancies, such as planes, trains, and automobiles.

ASHRAE will continue to support research that advances the knowledge base of indoor airmanagement strategies aimed to reduce occupant exposure to infectious aerosols. Chief
among these ventilation-related strategies are dilution, airflow patterns, pressurization,
temperature and humidity distribution and control, filtration, and other strategies such as ultraviolet germicidal irradiation (UVGI). While the exact level of ventilation effectiveness varies with local conditions and the pathogens involved, ASHRAE believes that these techniques, when properly applied, can reduce the risk of transmission of infectious diseases through aerosols. To better specify the levels of certainty behind ASHRAE’s policy positions stated herein, we have chosen to adopt the Agency for Healthcare Research and Quality (AHRQ) rubric for expressing the scientific certainty behind our recommendations (Burns et al. 2011). These levels of certainty, as adapted for this position document, are as follows:

Evidence Level Description
AStrongly recommend; good evidence
BRecommend; at least fair evidence
CNo recommendation for or against; balance of benefits and harms too close to justify a recommendation
DRecommend against; fair evidence is ineffective or the harm outweighs the benefit
EEvidence is insufficient to recommend for or against routinely; evidence is lacking or of poor quality; benefits and harms cannot be determined

ASHRAE’s position is that facilities of all types should follow, as a minimum, the latest published standards and guidelines and good engineering practice. ANSI/ASHRAE Standards 62.1 and 62.2 (ASHRAE 2019a, 2019b) include requirements for outdoor air ventilation in most residential and nonresidential spaces, and ANSI/ASHRAE/ASHE Standard 170 (ASHRAE 2017a) covers both outdoor and total air ventilation in healthcare facilities. Based on risk assessments or owner project requirements, designers of new and existing facilities could go beyond the minimum requirements of these standards, using techniques covered in various ASHRAE publications, including the ASHRAE Handbook volumes, Research Project final reports, papers and articles, and design guides, to be even better prepared to control the dissemination of infectious aerosols.

Standards organizations offer free access to standards and resources to fight COVID-19

AAMI, IEEE, ASTM, and ANSI are providing free access to key standards and other information to help fight COVID-19.

ASTM Standards & COVID-19

ASTM International is providing no-cost public access to important ASTM standards used in the production and testing of personal protective equipment – including face masks, medical gowns, gloves, and hand sanitizers – to support manufacturers, test labs, health care professionals, and the general public as they respond to the global COVID-19 public health emergency.

Efficiency requirements for residential central AC and heat pumps to rise in 2023

Read the full story from the Energy Information Administration.

Beginning in 2023, all new residential central air-conditioning and air-source heat pump systems sold in the United States will be required to meet new minimum energy efficiency standards. The most recent minimum energy efficiency standards for these equipment types went into effect in 2015, and for the first time, separate standards were set for cooling central air conditioners sold in the northern parts of the United States and those sold in the southern parts. The new standards continue to set different cooling efficiency levels for air conditioners in the south, and they also require an increase in the heating efficiency of all air-source heat pumps.

New global sustainability standard for solar modules in the works

Read the full story at pv magazine.

Dustin Mulvaney is a solar industry veteran. Associate professor at the Department of Environmental Studies, San José State University, in the United States, he recently published a new book this April, Solar Power, Innovation, Sustainability, Environmental Justice, which looks at creating a “more sustainable and just solar industry for the future.” A part of this is the creation of a new global sustainability module standard. He spoke with pv magazine as part of the launch of our new UP initiative.

Webinar: Technical proposals putting the 2021 IECC on a glide path to efficiency

Tue, Mar 5, 2019 12:00 PM – 1:00 PM CST
Register at https://register.gotowebinar.com/register/6208413692984890883

Updating of the 2021 International Energy Conservation Code (IECC) is underway! Join a free webinar hosted by New Buildings Institute and the Energy Efficiency Codes Council to hear from experts working on the 2021 IECC update. Attendees will learn about the efficiency proposals that would improve design and construction approaches and deliver 10-15% better efficiency. The 2021 version of IECC will have decades-long impacts on the energy performance of buildings and presents the best near-term opportunity to dramatically reduce energy use and carbon emissions from new residential and commercial construction projects. The built environment accounts for roughly 70% of the electricity and 40% of the carbon emissions in the U.S. Better energy codes also means more comfortable and heathier living, working and learning spaces, increased property values, and lower operating costs.

Proposals submitted to the IECC will come up for a vote by members of the International Code Council (ICC) in fall of 2019. Although this process is almost a year long, local governments have only until March 29, 2019, to join the ICC or renew membership, a requirement for voting to move this national model energy code forward. This webinar will also review the process for how the 2021 IECC is developed and what jurisdictions and others can do to make their voices heard.
