Building Science Resource Library
The Building Science Resource Library contains all of FEMA’s hazard-specific guidance that focuses on creating hazard-resistant communities.
You can search for a document by its title, or filter the collection to browse by:
- Topic: High winds, flood, earthquake, etc.
- Document Type: Brochure, report, fact sheet, infographic, etc.
- Audience: Building professionals & engineers, individuals & homeowners, teachers & kids, etc.

This catalog includes FEMA’s natural hazard-specific guidance that focuses on creating hazard-resistant communities conveniently in one place. The publications are organized by primary hazard (earthquake, flood, high wind, multi-hazard, and other) and then by stakeholder groups.
Floodwaters can submerge critical equipment, hurricane-force winds can rip sections of roofing off production facilities, and earthquakes can bring down suspended ceilings in office facilities.
Following a series of heavy snow and wind events in February of 2015, a FEMA team assessed four partial school building collapses in the Greater Boston area. In all four cases, the partial collapses were due to roof snowdrift loading. In two of the four cases, the FEMA team observed and documented 3-D drifts that cannot be determined when following the current ASCE 7 minimum load requirements.
This new design guide provides guidance, in the form of three design examples, for three-dimensional (3-D) roof snowdrifts. The procedures identified are consistent with the intersecting drift provisions expected in the 2022 edition of ASCE 7 and are intended to serve as best practice guidance for design professionals in the interim.
The conclusions and recommendations of this report are intended to provide decision-makers and design professionals with information and technical guidance that can be used to reduce future damage from snow loads.
Returning to your fire-damaged home will undoubtedly be an emotional experience. But as you go about the task of rebuilding, there are many ways to rebuild safer, stronger, smarter and more resilient to wildfires. The Federal Emergency Management Agency (FEMA) has teamed with Firewise Communities, the Federal Alliance for Safe Housing, and the Institute for Business and Home Safety to provide this resource for rebuilding after a fire.
This flyer summarizes warning signs of overstress conditions during a snow event, key safety issues and risks a snow event poses to buildings, and what to do after a snow event.
The objective of the Risk Management Series Snow Load Safety Guide is to inform building stakeholders about the risks a snow event poses to their buildings, provide them with information about preventative measures to take before the snow season and inform them of actions that should be taken before, during, and after a snow event. This document is not intended to provide a comprehensive discussion of the underlying issues or forensics of snow-induced structural failure. The purpose is instead to: 1. Inform building stakeholders of susceptible snow loading conditions 2. Identify potentially vulnerable roof framing systems 3. Outline a general methodology to monitor buildings for signs of potential failure so that steps can be taken to reduce the potential risk of snow-load-induced structural failure
This is one in a series of publications that were developed in response to September 11, 2001, terrorist attacks on the New York World Trade Center and the subsequent events that led to the formation of DHS and an increased emphasis on preparedness and mitigation of terrorism-related hazards. One issue that FEMA began shortly after that was to examine whether lessons learned in response to natural hazards could be effectively applied to protect building occupants from human threats. Important similarities between seismic and blast loadings lend themselves to such examination.
This table is a comparison of the provisions of the 2009 I-Codes/ASCE 24-05 and the National Flood Insurance Program (NFIP) requirements.
The purpose of these Technical Fact Sheets is to provide information about wildfire behavior and recommendations for building design and construction methods in the wildland/urban interface. Implementation of the recommended design and construction methods can greatly increase the chances of a building’s survival in a wildfire.
