ENERGY MODEL VALIDATION FOR INDOOR OCCUPANT HEAT STRESS ANALYSIS
To be more resilient to heat waves, buildings will need
the capacity to provide habitable indoor conditions
without power for limited amounts of time. The wetbulb
globe temperature (WBGT) heat index is proposed
for use as a ‘passive habitability’ metric for evaluating
indoor occupant heat stress risk. A method is presented
to evaluate occupant heat stress vulnerability by
calculating WBGT values using energy model outputs
(Ta, To, RH, and zone infiltration), an indoor WBGT
equation, and standard heat stress threshold charts. An
analysis of the heat stress evaluation method illustrates
the need for simulations to include heat wave weather
data inputs. A method validation study compares
measured WBGT values from an existing
unconditioned space with WBGT values calculated
using an energy model of the space; a linear regression
comparison illustrates a high R-Squared of 0.9223.
