Data-Driven Decarbonization with C.Scale

Presentation to AIA Los Angeles Tech Rize 2024.

1. Data-Driven
Decarbonization

Next generation tools to spur climate action
on every project

Building Reuse

and Reuse of Existing
Structures

Components: Existing primary
structural elements, enclosure, (oof
framing, wall framing, and exterior
finishes).

Exceptions: Additions 2x the area.
‘or more of the existing building.

Exclude: Window assemblies,
insulation, portions structurally
unsound or hazardous, and
hazardous materials that are
remediated as part ofthe project
shall not be included in the
‘calculation.

Exception: Concrete mixes can
use a weighted average for all
mixes.
