Net/Gross Research Study


The purpose of the study is to establish a publicly accessible database
of healthcare and hospital area calculations that can be updated and
maintained over time. The searchable database will contain collected
data on industry trends for the ratio between departmental net and
departmental gross square-footage in significant departments/units
within hospitals. The ultimate goal is to provide comparison data from
programs of space requirements and the buildings that resulted. The goal
is to make planning data available to the industry in a way that allows
for better predictions of square footage requirements and improved
performance of healthcare buildings.

The study builds on the basis of a preliminary study, "Analysis of
departmental area in contemporary hospitals: calculation methodologies
and design factors in major patient care departments," as conducted by
David Allison of Clemson University and D. Kirk Hamilton of Texas A&M
University. The findings of the previous study are available online at:
