## Key facts

| Fact | Value |
| --- | --- |
| Defined in | IECC 2009 (2009 editions transcribed in this corpus) |
| Primary source | IECC 2009 Definitions (model text, not a jurisdiction's adopted text) |
| Chapters using the term | 7 (counted across the codes hosted here) |
| Wording identical across codes | Single code (compare before citing one code's wording under another) |

## Direct answer

Entrance door is a defined term in the International Energy Conservation Code (IECC) 2009, in Definitions. The code's own words are: “Fenestration products used for ingress, egress and access in nonresidential buildings, including, but not limited to, exterior entrances that utilize latching hardware and automatic closers and contain over 50-percent glass specifically designed to withstand heavy use and possibly abuse.” No other I-Code in this corpus defines it, so the IECC 2009 definition is the one to work from. The term is used in 7 chapters of this corpus, most often in Commercial Energy Efficiency (IECC 2009), Means of Egress (IFC 2009), Explosives and Fireworks (IFC 2009). These pages transcribe the 2009 model text; verify the definition against the edition and amendments your authority having jurisdiction has adopted.

## What must be verified before using this guidance?

**Entrance Door** is defined once in this corpus, in the [Definitions](https://harth.build/resources/building-codes/us-states/maryland/iecc-2009/definitions.md) chapter of the International Energy Conservation Code (IECC) 2009:

## The terms entrance door is built out of

The definition above leans on 2 other defined terms. Each carries its own code definition, and a local amendment to any of them changes what entrance door covers:

- **[Fenestration](https://harth.build/resources/glossary/fenestration.md)** — IRC 2009: Skylights, roof windows, vertical windows (whether fixed or moveable); opaque doors; glazed doors; glass block; and combination opaque/glazed doors.
- **[Automatic](https://harth.build/resources/glossary/automatic.md)** — IBC 2009: As applied to fire protection devices, a device or system providing an emergency function without the necessity for human intervention and activated as a result of a predetermined temperature rise, rate of temperature rise or combustion products.

## Entrance Door: what to open, and in what order

Every row is a document this term depends on. The [ICC code library](https://codes.iccsafe.org/codes) and the [ICC adoption maps](https://www.iccsafe.org/advocacy/code-adoption-maps/) cover the middle rows.

## Frequently asked questions

### What is the code definition of entrance door?

The International Energy Conservation Code (IECC) 2009 defines it in Definitions as: “Fenestration products used for ingress, egress and access in nonresidential buildings, including, but not limited to, exterior entrances that utilize latching hardware and automatic closers and contain over 50-percent glass specifically designed to withstand heavy use and possibly abuse.” The 2009 model text is reproduced here; the definition that binds your project is the one in the edition your jurisdiction has adopted, as amended locally.

### Which parts of the code depend on entrance door?

In this corpus the term is used across 7 chapters, led by Commercial Energy Efficiency in the IECC 2009. Those are the sections whose scope moves if the definition is amended locally, so read them together with Chapter 2 rather than on their own.

### What is an entrance door?

In the 2009 I-Codes hosted here it is a defined term rather than a description. The IECC 2009 states, in Definitions: “Fenestration products used for ingress, egress and access in nonresidential buildings, including, but not limited to, exterior entrances that utilize latching hardware and automatic closers and contain over 50-percent glass specifically designed to withstand heavy use and possibly abuse.” It is defined in IECC 2009. Because it is a defined term, whatever the adopted edition says it means is what every section using it means — so check Chapter 2 of that edition and any local amendment before relying on this wording.

### What are the requirements for exterior doors in the North Carolina building code?

Building is a separate defined term. The IBC 2009 defines it as: “Any structure used or intended for supporting or sheltering any use or occupancy.” That is not the same as entrance door, which the IECC 2009 defines as “Fenestration products used for ingress, egress and access in nonresidential buildings, including, but not limited to, exterior entrances that utilize latching hardware and automatic closers and contain over 50-percent glass specifically designed to withstand heavy use and possibly abuse.” — read both before applying either, and confirm the wording in the edition your jurisdiction has adopted.
