Editing Indoor heat exposure index (section)

== Aggregation Semantics ==
Geographically, the indoor heat exposure index can be aggregated across spatial units ranging from individual dwellings to neighborhoods, cities, or broader regions, depending on data availability and study objectives. Temporal aggregation may involve averaging or summarizing index values over hours, days, or longer periods to capture exposure patterns. Cross-signal aggregation can integrate this index with related environmental signals such as electricity service outage duration or heat-related health outcomes to provide a comprehensive assessment of heat vulnerability and risk. Aggregation methods should consider variability in building characteristics and occupant behaviors to maintain representativeness.
