Substantial progress in our understanding of human response to thermal environments has
been made since Standard 55- 1992, including the amendment 55-95a. Incorporating many of
these advances, Standard 55-2004, Thermal Environmental Conditions for Human Occupancy,
was recently published after completing four public reviews and receiving approval by both
ASHRAEand the American National Standards Institute (ANSI).
The standard specifies conditions of the indoor thermal environment that occupants will find
acceptable. It is intended for use in design, commissioning, and testing of buildings and other
occupied spaces and their HVAC systems, and for the evaluation of existing thermal environments.
Because of the inherent variations in occupantsʹ metabolic rates and clothing levels, and because
it is not possible to prescribe or enforce what these should be, this standard cannot practically
mandate operating setpoints for buildings.
The two most important additions included in this new standard are an analy1ical method based
on the PMV-PPD indices and introduction of the concept of adaptation with a separate method
for naturally conditioned buildings. The adaptive model and several other changes are based
on various ASHRAE sponsored research projects. This article provides an overview of the key
features and limits of applicability of Standard 55-2004.
