CASCA

Shape the building.
See the consequence.

CASCA brings advanced building analysis into the design process. Change the building, room, glazing or materials and see what that decision means for energy, thermal comfort, daylight, acoustics and carbon—while the design can still change.

Change the opening.

A larger glazed area changes the questions you ask about solar gain, daylight, thermal comfort and façade carbon.

01 / Define the question

One decision.
Several consequences.

A different layout. Another construction. New glazing, shading or occupancy assumptions. CASCA connects building, room and component decisions in one workflow, so you can understand the consequences before the design is fixed.

Who it is for

Better questions.
Better buildings.

One analysis workflow, with a different purpose for each person shaping the design.

Architects & designers

Test geometry, materials and envelope choices while the design is still open. Keep performance in the design conversation.

Design decisions ↗

Engineering & sustainability consultancies

Compare alternatives on a consistent basis and bring energy, comfort, daylight, acoustics and carbon into technical reviews.

Consulting studies ↗

Academic teaching

Let students change an assumption and explain the result. Connect building physics to design studio and technical coursework.

Teaching with CASCA ↗

Researchers

Explore sensitivities and controlled scenarios, with a clear assessment boundary and repeatable inputs for methodological review.

Research workflows ↗

Real estate & developers

Compare new-build and retrofit options before committing to a specification. Understand operational demands, occupied conditions and material impacts.

Property decisions ↗

Homeowners & consumers

Explore how glazing, insulation and shading choices could affect your home. Take more informed questions to your designer or consultant.
