Health care facilities are among the largest and most energy-intensive buildings in a community, and their leadership recognizes that opportunities to conserve energy, reduce operating costs, and improve the environment are included in their stewardship with the communities they serve. However, there are limitations in the competitive and regulated market for providing the increasingly advanced building systems required for modern health care balanced with sustainability objectives. Requirements for safety can be at odds with sustainability goals, for example. This standard therefore prescribes the procedures, methods, and documentation requirements for the design, construction, and operation of high-performance, sustainable health care facilities.

HVAC systems are built to keep the indoor air quality (IAQ) safe for patients. Because of the airflow standards, equipment must meet high ventilation rates and filtration requirements. Healthcare facilities serve a critical service, and they must consider several factors to provide adequate public health. Among the concerns for health care facilities is airflow ventilation.
In healthcare facilities, humidifiers prevent the spread of bacteria and viruses. The standard's (ANSI/ASHRAE/ASHE 170) ventilation system addresses temperature and humidity that could be compromised without the proper attention and care.

This standard is also available to be included in Standards Subscriptions. Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. Subscription pricing is determined by: the specific standard(s) or collections of standards, the number of locations accessing the standards, and the number of employees that need access.
As the voice of the U.S. standards and conformity assessment system, the American National Standards Institute (ANSI) empowers its members and constituents to strengthen the U.S. marketplace position in the global economy while helping to assure the safety and health of consumers and the protection of the environment.
1. PURPOSE: The purpose of this standard is to define ventilation system design requirements that provide environmental control for comfort, asepsis, and odor in health care facilities.
2.1 The requirements in this standard apply to patient-care areas and related support areas within health care facilities, including hospitals, nursing facilities, and outpatient facilities.
2.3 This standard considers chemical, physical, and biological contaminants that can affect the delivery of medical care to patients; the convalescence of patients; and the safety of patients, health care workers, and visitors.
Recently, the American National Standards Institute (ANSI); American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE); and the American Society for Healthcare Engineering (ASHE) banded together to update their joint standard on Ventilation of Health Care Facilities.
Depending on the type of space within your facilities, the required particle efficiency may be as low as MERV 8, or as high as HEPA. The good news is that the clean air experts at AAF Flanders can help you ensure that your spaces comply with this updated standard.
This standard specifies acceptable levels of contaminants (purity requirements) for fluorocarbon, hydrocarbon, and carbon dioxide refrigerants regardless of source and lists acceptable test methods. These refrigerants are as referenced in the ANSI/ASHRAE Standard 34 with Addenda and in ISO Standard 817:
NARA is authorized to establish, maintain and operate records centers for Federal agencies under 44 U.S.C. 2907. NARA is authorized, under 44 U.S.C. 3103, to approve a records center that is maintained and operated by an agency. NARA is also authorized to promulgate standards, procedures, and guidelines to Federal agencies with respect to the storage of their records in commercial records storage facilities. See 44 U.S.C. 2104(a), 2904, and 3102. The regulations in this subpart apply to all records storage facilities Federal agencies use to store, service, and dispose of their records. 2b1af7f3a8
