Enclosure

😌 Simple Editing

Choose from pre-defined enclosure carbon intensities.

Reuse

Solid Exterior Wall Reuse

The reuse of solid exterior wall for a given percentage of the building’s total enclosure.

Transparent Exterior Wall Reuse

The reuse of transparent exterior wall for a given percentage of the building’s total enclosure.

Roofing Reuse

The reuse of the roofing assembly for a given percentage of the building’s total roof area.

Note: these reuse measures only affect upfront emissions; refurbishments are counted normally.

Enclosure Specification

Carbon Intensity

The carbon intensity of the enclosure assemblies. C.Scale includes a dynamic enclosure model which allows users to input very general data (when very little is known) or very specific data (during later stages of design). When specific data is not known, the app includes C.Scale's pre-defined carbon intensities, defined by the levels of ambition.

Enclosure Carbon Intensity Choices
  • Low Carbon (20th percentile). 20th percentile of GWP for solid exterior wall, transparent exterior wall and roofing assemblies.

  • Average (50th percentile). 50th percentile of GWP for for solid exterior wall, transparent exterior wall and roofing assemblies.

  • High Carbon (80th percentile). 80th percentile of GWP for solid exterior wall, transparent exterior wall and roofing assemblies.

Service Life

The length of time over which a majority of the enclosure will be replaced.

Takeoffs

Material takeoffs are displayed for the total exterior wall, solid exterior wall, transparent exterior wall, and roofing.

🤓 Detailed Editing

The Assemblies Configurator is designed to support the input of more detailed, project-specific data.

To begin using this feature, turn on Use Assemblies within the Enclosure accordion, and then click "Configure Assemblies".

Turn on "Use Assemblies".

Solid Exterior Wall Assemblies

When more data is available, C.Scale allows you to define specific cladding assemblies, exterior insulation types, and wall framing assemblies. C.Scale will apply your reuse, carbon intensity, and service life settings from the "simple" enclosure editor to an "undeclared" assembly that can be configured in greater detail. C.Scale will use your description of the solid exterior wall (i.e., any declarations of specific materials) to subset our library of solid exterior wall assemblies to only those meeting your criteria. This allows the user to know the range of potential carbon intensities available both within and between their declared design.

You can configure solid exterior wall assemblies using the following fields:

Quantity

The percentage of total solid exterior wall area where the assembly is applied.

Cladding Type

The outermost material layer exposed to weather.

Cladding Type Choices
  • Thin Brick

  • EIFS

  • Fiber Cement

  • Wood Siding

  • Profiled Metal Panel

  • Composite Metal Panel

  • Glass Fiber Reinforced Concrete

  • Stone Veneer

  • Terracotta

Exterior Insulation

The insulation layer installed on the exterior side of the wall structure.

Exterior Insulation Choices
  • Mineral Wool

  • Polylso

  • XPS

  • EPS

Framing

The primary structural material in the wall.

Framing Choices
  • 6 in. CMU

  • 6 in. Metal Stud

  • 2x6 Wood Stud

R-Value / RSI

The thermal resistance of the assembly. C.Scale applies default values based on the project's climate zone.

Material Origin

The source of the material.

Carbon Intensity

The carbon intensity of the configured assembly, taking into account the thickness of exterior insulation required to achieve the R-Value / RSI.

Solid Exterior Wall Carbon Intensity Choices
  • Low Carbon (20th percentile). 20th percentile of GWP for the configured solid exterior wall assembly.

  • Average (50th percentile). 50th percentile of GWP for the configured solid exterior wall assembly.

  • High Carbon (80th percentile). 80th percentile of GWP for the configured solid exterior wall assembly.

Service Life

Number of years over which at least half of the assembly’s components will be replaced.

Transparent Exterior Wall Assemblies

When more data is available, C.Scale allows you to define specific glazing units, mullions, and insulation. C.Scale will apply your reuse, carbon intensity, and service life settings from the "simple" enclosure editor to an "undeclared" assembly that can be configured in greater detail. C.Scale will use your description of the transparent exterior wall (i.e., any declarations of specific materials) to subset our library of transparent exterior wall assemblies to only those meeting your criteria. This allows the user to know the range of potential carbon intensities available both within and between their declared design.

Quantity

The percentage of total transparent exterior wall area where the assembly is applied.

Glazing Type

The type of transparent assembly.

Glazing Type Choices
  • Curtain Wall

Glazing Unit

The transparent portion of a window assembly

Glazing Unit Choices
  • Double-Glazed IGU

  • Triple-Glazed IGU

  • Closed Cavity Facade

Frame

The frame material of a window assembly.

Frame Choices
  • Aluminium

  • Timber/Aluminium

Material Origin

The source of the material.

Carbon Intensity

The carbon intensity of the configured assembly.

Transparent Exterior Wall Carbon Intensity Choices
  • Low Carbon (20th percentile). 20th percentile of GWP for the configured transparent exterior wall assembly.

  • Average (50th percentile). 50th percentile of GWP for the configured transparent exterior wall assembly.

  • High Carbon (80th percentile). 80th percentile of GWP for the configured transparent exterior wall assembly.

Service Life

Number of years over which at least half of the assembly’s components will be replaced.

Roofing Assemblies

When more data is available, C.Scale allows you to define specific roof types, insulation and R-Values/ RSI. C.Scale will apply your reuse, carbon intensity, and service life settings from the "simple" enclosure editor to an "undeclared" assembly that can be configured in greater detail. C.Scale will use your description of the roof (i.e., any declarations of specific materials) to subset our library of roofing assemblies to only those meeting your criteria. This allows the user to know the range of potential carbon intensities available both within and between their declared design.

Quantity

The percentage of total roof area where the assembly is applied.
