Today at 15:00 UTC we examine the technical literature about rainwater management in schools, colleges and universities — underfoot and on the roof. Lightning protection standards will also be reviewed; given the exposure of outdoor athletic activity and exterior luminaires.
We draw from previous standardization work in titles involving water, roofing systems and flood management — i.e. a cross-cutting view of the relevant standard developer catalogs. Among them:
American Society of Civil Engineers
American Society of Plumbing Engineers
ASHRAE International
ASTM International
Construction Specifications Institute (Division 7 Thermal and Moisture Protection)
Federal Emergency Management Agency
FM Global
IAPMO Group (Mechanical and Plumbing codes)
Institute of Electrical and Electronic Engineers
Heat Tracing Standards
International Code Council
Chapter 15 Roof Assemblies and Rooftop Structures
National Fire Protection Association
National Electrical Code: Article 250.16 Lightning Protection Systems
Lightning Protection
Underwriters Laboratories: Lightning Protection
Readings: The “30-30” Rule for Outdoor Athletic Events Lightning Hazard
