Conference Paper Session 14 Ventilation Requirements in Health-Care

Indoor Environment: Health, Comfort, Productivity
Chair: Roger Lautz, P.E., Affiliated Engineers, Inc.
The first two papers in this session compare ventilation standards from four countries, the U.S., Germany, The United Kingdom and Spain, for both operating rooms and patient bed areas. The third presentation discusses ventilation requirements in outpatient facilities in the context of both patient protection and energy use.

1  Minimum Ventilation Requirements in Operating and Procedure Rooms: A Comparison of International Standards (ST-16-C040)

There are significant differences in international health care ventilation standards.  This paper is one in a series of benchmarking investigations of those variances. These studies identify and capture best practices from among the international standards.

This paper compares minimum ventilation requirements for operating rooms and procedure rooms, from four international standards. The standards compared are; ASHRAE-170 Ventilation for health care facilities (US),  DIN-1946 – VAC systems in buildings and rooms used in the health care sector (Germany), HTM-03-01 Specialized ventilation for health care premises (UK), and UNE 100713 Instalaciones de acondicionamiento de aire en hospitales (Spain).

The comparison identifies the minimum (i.e. most permissive) ventilation requirements in six different requirement areas:  outdoor air ventilation, total room air ventilation, supply air filter efficiency, room temperature, room humidity and room pressurization.  Results are normalized to common units, compared and discussed in context of the four standards.

2  Minimum Ventilation Requirements in Patient Bed Areas: A Comparison of International Standards (ST-16-C041)

3  Application of Health Care Ventilation Standards to Outpatient Facilities (ST-16-C042)

 Maya Salabasheva, P.E., Kaiser Permanente

This paper is a result of tireless pursuit of reducing health sector energy consumption and associated climate footprint.  Fossil fuel combustion related to energy use in buildings produces not only global warming gases such as carbon dioxide, but also series of other pollutants that contribute to the environmental burden of diseases and the increase of healthcare costs.

This paper outlines three alternatives for addressing ventilation in outpatient facilities, within and out of the context of the current ASHRAE Standard 170 “Ventilation for Health Care Facilities”. It compares the current requirements of Standard 170 to those of B occupancy areas in outpatient health care facilities such as medical office buildings (MOBs) and ambulatory surgery centers (ASCs).
