Accessory

Any component contributing to the fixing or the retention of a construction element to another element or its support 

Beam

Hot-rolled long product whose cross-section resembles the shape of the letters I, H or U and whose height is at least 80 mm. 

Cladding

Exterior facing on facade having trapezoidal or corrugated ribs providing inertia and stiffness, possibly applied to a self-supporting façade, mechanically fastened to the main frame, to the secondary structure, or to the lips of the liner trays. This product is made from a cold-formed pre-painted or stainless steel sheet, with various waveforms. Cladding is available in the form of single-skin, double-skin and sandwich panels. 

Composite floor

Steel trough in combination with a concrete slab to constitute the formwork during pouring and then the main reinforcement in service as a composite floor. The two components (steel and concrete) work together to withstand the floor loadings. This composite action is achieved by appropriate processing of the sheet forming the trough (bosses, connectors, special rib form). 

Construction product

Any product or kit manufactured and placed on the market for permanent incorporation into construction works or parts of construction works, and whose performance affects the performance of the construction works as regards the fundamental requirements applicable to such works (according to the Construction Product Regulations).

Environmental performance

Performance related to environmental impacts and environmental aspects

Feedstock energy

This corresponds to the portion of the primary energy contained in the materials entering the system that are not used as fuel. This quantity of energy (net calorific value) can be recovered at end of life if the collection and recovery systems are available. 

Functional unit

Quantified performance of a product system for use as a reference unit in a life cycle analysis

Hazardous substances

These are dangerous substances as defined by European Directive 67/548/EEC as amended (Journal officiel de la République française [official gazette of the French Republic] decree dated 20/04/1994 relating to the declaration, classification, packaging and labelling of substances). 

Hollow section

Designation reserved for tubes for construction. They exist in various forms: square, rectangular, circular or even elliptical. They are produced by hot or cold forming with or without welding. 

Joist

Beam forming the direct or primary framework of a floor.Joists rest either on the walls of the building if it is traditional, or on larger beams if it is a steel or reinforced concrete frame.

Life Cycle Inventory

Phase of the Life Cycle Assessment (LCA) involving the compilation and quantification of inputs and outputs for a given product system throughout its life cycle 

Life cycle analysis (LCA)

Compilation and evaluation of the inputs, outputs and the potential environmental impacts of a product system throughout its life cycle 

"Life cycle" approach

The "life cycle" approach takes into consideration all the stages in the life of a product in order to assess the impact of the product design on the environment.
In standard NF P01-010, the stages in a construction product’s life cycle are:

-      production,

-      transportation,

-      deployment,

-      service life,

-      end of life.

Liner Tray

The liner tray is a profiled, generally U-shaped, component in steel with a protective coating, having a flat or slightly ribbed face forming the interior wall of the building. On the outer face, the liner trays arranged side by side incorporate lips that form supports with a total thickness of at least 1.5 mm for fixing the outer skin or the secondary structure.

Non-renewable energy

Energy from sources that are not defined as renewable energy sources. 

Non-renewable resource

Resource present in a fixed quantity that cannot be replenished within a human timescale 

Portal frame (simple)

Construction system comprising two vertical posts, connected at the top by a gabled (or straight) cross member, in which each connection to the posts forms a rigid housing 

Process energy

Energy input required by a unit process to operate the process or the corresponding equipment, excluding energy inputs for production and delivery of this energy.

Product system

Set of unit processes comprising product and unit flows, fulfilling one or more defined functions, which serves as a model for a product's lifecycle.

Purlin

Beam connecting roof trusses or portal frames, and transferring to them the forces transmitted directly by roofing elements or indirectly by the rafter

Rail

Horizontal beam forming the secondary structure of the facades in a frame, serving as a mounting for the cladding components, whether or not opaque.

Recovered materials and energy

Recovered materials and energy relate to by-products and products reused at end of life. Like the materials consumed during the product's life cycle, they may or may not appear as outputs in the inventory depending on the selected methodology applied to them.

Recovered waste

Any waste sent to stock for recovery 

Reference flow

Measurement of the process outputs in a given product system that are required to fulfil the function expressed by the functional unit 

Reference service life (RSL)

Service life that can be expected for a construction product according to a specific set (reference set) of service conditions and that can serve as a basis for estimation of the service life under other service conditions 

Renewable energy

Energy from renewable non-fossil sources.Examples:wind, solar, aerothermal, geothermal, hydrothermal, marine and hydroelectric energy, biomass, landfill gas, sewage treatment plant gas and biogas.

Renewable resource

Resource that increases, can be replaced or decontaminated naturally within a human timescale. NB: A renewable resource can potentially be exhausted, but can last indefinitely if properly managed. Examples: trees in forests, grass in pastures, fertile soils.

Roofcovering

Any system impervious to atmospheric precipitation, covering the upper part of buildings. The roofcovering is the external part of the roof. The metal elements used for roofcovering take the form of corrugated or ribbed sheets, panels, sheets, shells, etc., with the possible addition of a single-or multilayer weathertight seal.

Sandwich panel with steel facings

Construction product intended for construction of a wall (non-structural envelope) comprising two steel facings and an insulating core in accordance with standard NF EN 14509 or ETAG 16. The panel is capable of supporting its own weight by virtue of the materials of which it is manufactured and its form, and of transferring to its supports all forces applied.

Standing seam

Seam formed by folding, with or without lock beading, the two contiguous raised edges of two metal roofing panels or sheets.The standing seam is located along the line of greatest slope.

Steel

Iron-based alloy containing carbon (< 2%) and possibly additions known as alloying elements

Total primary energy

This represents the sum total of all sources of energy that are directly drawn from natural reserves, such as natural gas, oil, coal, uranium ore, biomass, hydropower, solar, wind and geothermal energy.

Total primary energy is divided into non-renewable energy and renewable energy on the one hand, and process energy and feedstock energy on the other. The following equation illustrates this definition:

Total primary energy = non-renewable energy + renewable energy.

  = process energy + feedstock energ

Typical service life (TSL)

Typical service life of the product selected for the functional unit 

Unit process

The smallest element considered in the life cycle inventory analysis for which input and output data are quantified. 

Waste

Any residue of a process of production, processing or use, any substance, material, product or more generally any movable asset that has been or will be discarded by the owner (Article L541-1.II of the Environmental Code)

In standard NF P01-010, waste is defined in terms of flows, in accordance with the classification in force on the date of its publication, namely:

-      hazardous waste,

-     non-hazardous waste,

-      inert waste,

-      radioactive waste.

Welded plate section

Section obtained by welding of flat products. These are generally beams consisting of a web welded onto two flanges.

Windbracing

Construction system ensuring stability of a structure, subjected one or more given forces (wind, earthquake, etc.) in one or more given directions. Windbracing can be achieved by various means: rigid partition, cross-braced frame (e.g. St. Andrew’s cross), rigid portal frame, concrete core, etc.
