SC Engineers' Principals Frank Shadpour, PE, and Stefanie Johnson share recommendations and lessons learned in conjunction with the California Department of Health Care Access and Information (HCAI) to set-up makeshift negative pressure patient rooms in two major hospitals located in San Diego, CA in response to the COVID-19 pandemic. The article received the title of "Best Article of 2020" by the ASHRAE Journal.
Everyone knows that installing new HVAC systems and equipment within an existing hospital requires extensive research, design, regulatory permits and, most importantly, time. But when you must create a large number of negative pressure hospital patient rooms in response to a pandemic, you don’t have much time. Instead, you can create these rooms using appliances such as portable high-efﬁciency particulate air (HEPA) exhaust fan units, with guidance from relevant codes and standards and by following hospital licensing requirements.
