What engineering challenges do hospitals and healthcare facilities pose that are different from other structures ? MG : There are two major engineering differences between hospitals and other structures , energy usage and infection control . A typical hospital structure is the second biggest energy user per square foot of any structure , the largest energy consumer are fast food restaurants . The principal contributors to high energy use in hospitals are fan energy and lighting levels . The filtration and air exchange requirements are much greater than those of other structures since the mechanical systems are required to not only maintain temperatures but also prevent the spread of infectious conditions between patients . Another big challenge is the medical gas systems within a hospital for which the plumbing engineer is responsible . Typical medical gas systems are comprised of oxygen , medical-grade air , vacuum and other gases such as nitrogen and nitrous oxide .
What is the most challenging aspect of working in an existing hospital ? MG : One of the most challenging aspects of designing MEP systems in a hospital environment is getting access to verify existing conditions and ensuring that the MEP systems remain fully active to all parts of the hospital 24 / 7 .
How have the needs and characteristics of hospitals changed in recent years ? MG : The need for hospitals to be more energy efficient and the constantly changing technology required for modern day healthcare are the current drivers of change within the hospital environment . Another evolving trait is that of more outpatient services than inpatient care . This trend requires more medical office buildings to be used for typical inpatient care than a hospital .
