Option comparison
Compare competing design assumptions while geometry, assemblies and facade strategy can still change.
Read more →The focused carbon platform for facade and building option studies.
Compare embodied carbon, operational energy, comfort and whole-life carbon before the design is locked in.
Built for early-stage carbon decisions
Why CASCA?
Make carbon, energy and comfort trade-offs visible earlier.
Early-stage inputs
Use available design information such as building use, element groups, build-ups, quantities and area.
Read more →
Carbon hotspots
See where embodied carbon is concentrated, so design effort can be focused on the right assemblies.
Read more →
Energy implications
Review annual and monthly energy results alongside carbon, rather than treating them as separate studies.
Read more →
Comfort risk
Expose overheating and comfort implications that may be hidden by carbon-only option appraisal.
Read more →
Life-cycle modules
Review embodied carbon through clear A1-A3, A4-A5, B1-B5 and C1-C4 module breakdowns.
Read more →Use cases
Carbon, energy and comfort workflows for design, research and teaching.
Facade designers
Compare facade and envelope options before systems and assemblies are fully fixed.
Read more →Architects
Test early material, glazing and building assumptions with carbon and comfort consequences visible.
Read more →Project teams
Use a consistent comparison basis to support design workshops and option appraisal.
Read more →Envelope consultants
Connect facade performance, build-up choices and operational results in one workflow.
Read more →Sustainability consultants
Support early whole-life carbon discussions before detailed specification data is available.
Read more →Energy modellers
Use simulation outputs alongside embodied carbon when reviewing options and assumptions.
Read more →Scenario studies
Test the effect of changing assemblies, glazing, orientation, weather and comfort criteria.
Read more →Method comparison
Study relationships between embodied carbon, operational performance and whole-life totals.
Read more →Repeatable studies
Create structured outputs for technical review, reporting and repeatable comparison.
Read more →Design studios
Show students how early facade and material choices affect carbon, energy and comfort.
Read more →Carbon literacy
Make whole-life carbon relationships visible through simple inputs and clear outputs.
Read more →Assessment exercises
Use comparable scenarios to support teaching, tutorials and design-option discussions.
Read more →Where CASCA fits
More useful than a simple estimate. Lighter than a late-stage model.
Quick carbon estimates may miss operational energy and comfort risks.
Early-stage option studies with embodied carbon, simulation and comfort on one comparison basis.
Detailed tools can require information that is not available until decisions are already fixed.
