Emergency Escape & Rescue Openings ( EER or Egress)

Emergency Escape & Rescue (EER) is a requirement where basements, habitable attics and every sleeping room shall have at least one operable emergency escape and rescue opening.

Clear opening charts and EER units are available by going to a specific product page, clicking on the green tab labeled "Sizes, 2D & 3D Drawings, Clr Opgs, CSI Specs," then clicking "Misc - Specs, Opgs, Assembly." Or, they can be searched for in the Architect Library.)

DEFINITIONS

Attic, Habitable - A finished or unfinished area, not considered a story, complying with all of the following requirements:

  1. The occupiable floor area is at least 70 square feet
  2. The occupiable floor area meets ceiling height requirements
  3. The occupiable space is enclosed by the roof assembly about, knee walls (if applicable) on the sides and the floor-ceiling assembly below

Basement - The portion of a building that is partly or completely below grade

Clear Opening - Unobstructed area for exiting a window (clear opening charts are available by going to a specific product page, clicking on the green tab "Sizes, 2D & 3D Drawings, Clr Opgs, CSI Specs," then in the left tan area, clicking "Misc - Specs, Opgs, Assembly." Or, they can be searched for in the Architect Library.)

Daylight Area - Amount of visible glass as seen when looking through an installed window or door

Egress (Means of EGRESS) - A continuous and unobstructed path of vertical and horizontal egress travel (allowing exit from an egress-rated side-hinged door) from any occupied portion of a building or structure to a public way. A means of egress consists of three separate and distinct parts: the exit access, the exit, and the exit discharge. ("Egress" only pertains to some side-hinged doors.)

Emergency Escape & Rescue Opening (EER) - An operable exterior window, door or similar device that provides a means of escape and access for rescue in the event of an emergency.

Grade Floor Opening - A window or other opening located such that the sill height of the opening is not more than 44 inches (1118 mm) above or below the finished ground level adjacent to the opening

Habitable Space- A space in a building for living, sleeping, eating or cooking (bathrooms, closets, halls, storage or utility spaces and similar areas are not considered habitable spaces)

Vent Area (Ventilation Area) - When a window or door is in a fully opened position, vent is the area that allows airflow between the interior and exterior. For example, the vent area of a double hung window is the same as its clear opening; however the vent area of a casement window is typically larger than its clear opening due to the space between the sash and frame that's unaccounted for in the clear opening.
