Most model codes, such International Mechanical Code and International Plumbing Code, have three-year update cycles and some National Fire Protection Association codes like NFPA, National Electrical Code NFPA 101, Life Safety Code and NFPA 99, Health Care Facilities Code..
Throw in the authorities having jurisdiction with their code time frames and their amendments, and design project in 2015 might be using IBC, LSC and NEC..
In contrast, the 2003, 2009 and 2012 editions of LSC identify hospital and health care occupancy or medical care or treatment simultaneously to four or more patients on inpatient basis.
health care occupancy provides services or treatment simultaneously to four or more patients, on outpatient basis, treatment, anesthesia, emergency or urgent care that renders the patient of self-preservation or incapable of taking action for self-preservation under emergency conditions without the assistance of others..
The need for smoke compartmentation, horizontal exits, fire-rated walls and barriers or other areas of refuge add complexity to HVAC duct design and to the maintenance and operation if plan to avoid these dampers is not laid out.
One of the keys to planning and selecting HVAC system is to determine the codes to.
It's also worth noting that filter efficiency reporting value ratings, air flow supply and removal locations and direction, pressure relationships and sound transmission or noise criteria are identified for room types as health care design parameters and included as part of HVAC design criteria.
The owner or user has input into the project design and practices for the institution he or she will establish and convey any risk assessment associated with patient care and treatment through the infection control and safety staff to the design team..
model code occupancy requirements and referenced standards such as ASHRAE Standard 62.1 ANSI ASHRAE 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings and NFPA Standard 90A would need to be considered as part of HVAC design criteria..
Facility Guidelines Institute's Guidelines for Design and Construction of Hospitals and Outpatient Facilities, indicates air diffuser types and locations, filtration and air removal locations to meet effective design airflow and criteria.
