Changes in the healthcare industry have impacted the way healthcare facilities are designed and operated, according to an article on the EC & M website.

Since 2006 when the guidance was first published, LEED has progressed from version 2.0 to version 4 with LEED for Health Care introduced in 2011, which mandates an integrated design process as a prerequisite for health care facilities. Energy codes have become increasingly strict, and more projects are driven by a goal of zero net energy, the article said.
Plus, in 2014, the WELL Building Standard was introduced, which emphasizes health and well-being of building occupants.
