### 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's dynamic enclosure model lets you input general data early in design or specific data as it becomes available. When specific data isn't available, use C.Scale's pre-defined carbon intensities, defined by ambition level.
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 Design
The Detailed Design configurator supports the input of project-specific data.
To begin using this feature, turn on **Detailed Design** within the Enclosure accordion, and then click "**Configure Enclosure**".

### 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 applies your reuse, carbon intensity, and service life settings from the simple enclosure editor to an undeclared assembly that you can configure in greater detail. C.Scale uses your description of the solid exterior wall to filter the library to assemblies that meet your criteria, letting you see the range of potential carbon intensities available within and between your declared designs.
You can configure solid exterior wall assemblies using the table and the following fields in the right-hand panel:
#### 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 applies your reuse, carbon intensity, and service life settings from the simple enclosure editor to an undeclared assembly that you can configure in greater detail. C.Scale uses your description of the transparent exterior wall to filter the library to assemblies that meet your criteria, letting you see the range of potential carbon intensities available within and between your declared designs.
You can configure transparent exterior wall assemblies using the table and the following fields in the right-hand panel:
#### 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 applies your reuse, carbon intensity, and service life settings from the simple enclosure editor to an undeclared assembly that you can configure in greater detail. C.Scale uses your description of the roof to filter the library to assemblies that meet your criteria, letting you see the range of potential carbon intensities available within and between your declared designs.
You can configure roofing assemblies using the table and the following fields in the right-hand panel:
#### Quantity
The percentage of total roof area where the assembly is applied.
#### Roof Type
The type of roof assembly.
