Description

I-Codes

Rating that refers to the ability of a building component or assembly to withstand the effects of fire for a period of one hour without failing structurally or allowing the spread of fire through the assembly. It is a measure of the fire resistance or fire protection provided by the component or assembly. Depending on occupancy type, 2-, 3- and 4-hour rated walls may be required.

Illuminance

The amount of direct light falling on a horizontal surface called Horizontal Illuminance. Illuminance falling on a vertical surface or imaginary vertical plane is called Vertical Illuminance. The Imperial measure of Illuminance is footcandles (FC), which is Lumens per square foot. The metric measure of illuminance is Lux (Lx), which is lumens per square meter. One footcandle equals 10.56 Lux or approximately a 1:10 (FC:Lx) conversion.

Illuminating Engineering Society (ISE)
Illuminating Engineering Society of North America (IESNA)

A professional organization dedicated to advancing the art and science of lighting. It is recognized globally as an authoritative source of lighting knowledge and expertise. The IES focuses on promoting the understanding and application of lighting principles to enhance the quality of light and its impact on the built environment. It publishes illuminance guidelines for various building types and activities.

Institute of Transportation Engineers (ITE)

The dimension created by the overlap from the centerline of parking spaces configured in an angled parking layout. As the angle increases, this dimension decreases and vice versa. An interlock occurs with angled parking when two spaces in adjacent modules perfectly align, creating a herringbone pattern. The overlap of one of the stalls into the other's module is the interlock dimension.

Internal Combustion Engine

A type of heat engine that converts the chemical energy stored in a fuel into mechanical energy by burning the fuel inside the engine. It is the most common type of engine used in vehicles such as cars, motorcycles, and airplanes.

International Building Code (IBC)

The International Building Code (IBC) is developed and maintained by the International Code Council (ICC). The IBC is a set of standards and regulations for building design and construction that are widely used in the United States and other countries. It covers various aspects of building construction such as fire safety, structural design, accessibility, and energy efficiency.

The IBC is updated every three years to reflect new technologies, advancements in building science, and changes in societal needs. Its purpose is to ensure the safety and welfare of building occupants by establishing minimum requirements for the design, construction, and maintenance of buildings.

International Code Council (ICC)
The International Code Council (ICC) is a non-profit organization that develops and maintains a wide range of building safety codes and standards used in the United States and many other countries. It was established in 1994 by combining three separate model code organizations: the Building Officials and Code Administrators International (BOCA), the International Conference of Building Officials (ICBO), and the Southern Building Code Congress International (SBCCI).
 
The ICC is comprised of building safety experts and professionals in the construction industry, including architects, engineers, building officials, contractors, and others. The organization's mission is to develop and promote a comprehensive set of codes, standards, and guidelines that ensure the safety, sustainability, and resilience of buildings and communities.
 
The ICC's codes cover a wide range of areas, including building design and construction, fire safety, plumbing, mechanical systems, and energy efficiency. These codes are widely used and adopted by local and state jurisdictions across the United States and in other countries.
International Dark Sky Association (IDA)
A non-profit organization dedicated to preserving and protecting the night sky and reducing light pollution. The IDA promotes the importance of dark skies for astronomy, wildlife, human health, energy conservation, and the preservation of cultural heritage.
International Fire Code (IFC)
Part of a published family of "I-Codes." These firel codes are a comprehensive set of regulations and standards that provide guidelines for designing, constructing, and maintaining buildings and structures.
International Green Construction Code (IGCC)
Part of a published family of "I-Codes." These green construction codes are a comprehensive set of regulations and standards that provide guidelines for designing, constructing, and maintaining buildings and structures.
International Mechanical Code (IMC)
Part of a published family of "I-Codes." These mechanical codes are a comprehensive set of regulations and standards that provide guidelines for designing, constructing, and maintaining buildings and structures.
International Plumbing Code (IPC)
Part of a published family of "I-Codes." These plumbing codes are a comprehensive set of regulations and standards that provide guidelines for designing, constructing, and maintaining buildings and structures.
