Fresh air. Compliance+Operations. Fresh air. 08. 0. Dan Koenigshofer. P. E., MSPH, HFDP, SASHENew ASHRAE reference guides hospital HVAC design. The primary functions of a hospital HVAC system are improving indoor air quality and mitigating airborne transmission of diseases. This makes it much different from a typical building HVAC system, where comfort is the main objective. In fact, infection control experts have provided guidelines on hospital HVAC system filtration, temperature, humidity, air change, pressurization and exhaust, all in the name of providing superior patient care.
The recently released second edition of the American Society of Heating, Refrigerating and Air- Conditioning Engineers' (ASHRAE) HVAC Design Manual for Hospitals and Clinics incorporates this information into a convenient, detailed guide for HVAC engineers on how to design systems that meet infection control criteria, while also being reliable, low- maintenance and energy- efficient. Major changes. The second edition of the manual reflects major changes in health care engineering that have occurred since the first edition was published in 2. One of the biggest changes was the 2. ASHRAE Standard 1. Ventilation of Health Care Facilities. This landmark publication set the minimum standards for health care ventilation, air changes, temperature, humidity, filtration and design.
When it was adopted by the Facilities Guidelines Institute (FGI) as part of the 2. Guidelines for Design and Construction of Health Care Facilities, it became the minimum code adopted by more than 4. The new manual describes how to meet Standard 1. The manual also provides background on why and how these standards evolved.
Finally, it covers many topics that are not discussed in Standard 1. The manual assumes that the reader has a good knowledge of mechanical engineering and HVAC design. The primary audience comprises practicing consulting engineers who are designing hospitals.
However, the manual also is useful for facility engineers who wish to have a deeper understanding of how their HVAC systems work. It also may be used as a textbook for upper- division courses at colleges with health care engineering specialties. Hospital focus. The HVAC manual describes the relationship between infection control and HVAC design and explains how the different components of the HVAC system can influence the transmission of airborne microorganisms.

In fact, a 5. 0- page chapter is devoted to designing various types of critical rooms and areas within hospitals, such as operating rooms, isolation rooms, pharmacies, labs and imaging suites, and includes new data on energy use by various types of imaging systems. Another chapter is devoted to designing renovations with emphasis on system upgrades and infection control during construction. The manual explains pre- design testing and facility assessments in detail with photos, and covers the ranking of priorities and budgeting for master planning. Often, phasing considerations and utility shutdowns will have a significant influence on the engineering design for the 2.
It is virtually impossible to design a renovation project without consideration of the utilities that serve the project area as well as the spaces in proximity. It is common in existing hospitals that utility systems such as chilled water, hot water, emergency power and air changes are at their maximum. Renovations that require additional utilities may require upgrading systems well beyond project boundaries. Hospitals usually are strapped for floor space, especially in mechanical rooms.
Thus, it generally is difficult to replace devices such as air handling units in situ because of 2. A new mechanical room may be required to install a new air handling unit and associated equipment. After this equipment is all online, the old equipment and mechanical room can be cleaned and repurposed. Careful phasing is required to minimize disruption to patients and hospital operations during construction. The highest probability of airborne infection comes from construction activities within existing hospitals; as a result, infection control risk assessments and interim life- safety measures receive extensive attention in a chapter on operations and maintenance, written by a hospital engineer. Unlike many facilities, hospitals have year- round cooling loads, regardless of their location. Numerous factors unique to hospitals drive that cooling demand.
For instance, hospital buildings often have a low surface- to- volume ratio and they are less impacted by ambient weather. Moreover, hospitals contain numerous systems and devices that produce significant amounts of heat, such as imaging systems, refrigerators and intense lighting.
The chapter on utilities focuses on central energy plants, which are typical of most health care facilities. The design of central chilled water plants is described in the context of the performance objectives for the HVAC system within the hospital. The pluses and minuses of various energy- conservation strategies such as chilled beams, air and water economizers, and energy recovery systems are weighed. A deeper dive. The ASHRAE manual is written for experienced mechanical engineers who wish to dive deeply into health care engineering.
Toward that end, a good hospital HVAC system must meet all performance parameters (e. The manual discusses the delicate balance required to meet these objectives while also meeting stringent construction budgets.
Additionally, a chapter on sustainability includes a significant section on the environment of care. Generally, patients are much more sensitive than the general population in terms of the impact of temperature, humidity and air velocity.
Moreover, each area of the hospital likely will see a wide variety of patient sizes, ages and acuity, requiring the HVAC system to be highly flexible. The surgery department is the economic engine for most hospitals. It is also the department that generates the largest number of complaints about temperature and humidity. Humidity is probably the number one cause of HVAC complaints in health care. Many of these complaints, and all too often the fixes, are generated by a lack of understanding of psychrometrics. Unfortunately, the general public, operating engineers and even many consulting engineers lack the deep understanding of psychrometrics needed to design, build and operate HVAC systems that meet the demanding requirements of surgeons.
The manual's section on operating rooms also goes into considerable detail about meeting the low temperature and humidity desired by most surgeons. While ASHRAE S- 1.
HVAC systems be designed for a temperature of 6. Fahrenheit, most surgeons want the temperature considerably lower than that. Thus, it is essential to have an understanding of how hospital systems work and the impact that small changes in chilled water temperature can have on supply air temperature and humidity. Such energy conservation strategies jeopardize obtaining the exact temperature, humidity and air change requirements in the surgery area, resulting in complaints by the surgery staff.
Other key sections of the manual include: • A chapter on air handling and distribution systems that includes 6. HVAC systems with control schematics and descriptions of the nuances required to provide a high- performing and efficient HVAC system.• Chapters on the business of health care, disaster planning and emergency management, and operations and maintenance provide important background for any consulting engineer wishing to have a deep understanding of all aspects of hospital operations that affect engineering systems. The better a consultant understands his or her clients' needs, the more helpful the consultant can be.• A chapter on utilities that describes the design of boiler, chiller and emergency power systems to serve hospitals. Many hospitals desire HVAC and electrical systems that handle a wide variety of disasters. Cafeterias may be converted to emergency holding rooms.
Patients may have unknown contagious diseases. Chemical spills may require showering for scores of people.
Power outages can last for days. It is the responsibility of HVAC engineers to guide owners to make cost- effective decisions that meet their unique requirements. New data are presented in the manual for energy use and heat output by various types of imaging systems. The data are based on ASHRAE's research project on Method of Testing and Reporting of Energy Use by Medical Equipment. Through practical experience, the authors found that each of the three areas of an imaging suite — the equipment, control and patient rooms — needs its own thermostat and reheat box for individual temperature control. This is another example of a design consideration not specified in S- 1. The design manual also is based on the highly successful ASHRAE Learning Institute classes on Healthcare Facilities: Practices for Design & Application.
This course has been taught to more than 1,5. ASHRAE meetings. Finally, many associations representing pharmacists, material processing personnel and operating room nurses, have produced guidelines for temperature, humidity and air quality in their specific departments.
This manual describes how to design the HVAC system to meet these requirements. Pharmacies, in particular, require careful and unique engineering practices to meet demanding air quality and pressurization requirements.
A broad approach. The HVAC Design Manual for Hospitals and Clinics took a broad approach to providing hospital designers, consulting engineers and facility managers with this comprehensive resource. In fact, some of the design manual authors also have been involved in revisions to the 2.
