CASCA

Analysis for design decisions

One design.
More of the consequences.

CASCA brings energy, thermal comfort, daylight, acoustics and carbon into one design workflow. Define a building or room, change its geometry, materials or internal conditions, and compare the consequences before committing to a specification.

Change the design variables. Investigate their consequences.

Start with the right
scale of study.

01 / The room

The room, from every surface.

Define room geometry, location, orientation, construction, glazing, shading and internal conditions. Test the effects on operational energy and occupied conditions.

  • Dynamic thermal and energy simulation
  • Thermal comfort, overheating and daylight
  • Room acoustics and glazing option studies

02 / The building

The material picture.

Build up the project from components and assemblies. Review material impacts and whole-life carbon within the selected assessment boundary.

  • Building components and material quantities
  • Embodied carbon by life-cycle module
  • Project-scale carbon assessment

Six connected questions.

A useful option study explains what improves, what worsens and what needs a closer look. Keep the measures and units visible.

01

What does the room demand?

Heating, cooling and electricity over the year, with operational energy and carbon consequences.

kWh/m²·yr
Monthly and annual
02

How does it feel to occupy?

Thermal comfort and overheating, including the pattern of conditions during occupied periods.

PMV · PPD
Operative °C · TM52
03

Where does the daylight fall?

Daylight availability, useful illuminance and direct-sun exposure across the room.

lux · UDI · sDA · ASE
04

How does sound behave in the room?

External and internal noise, airborne sound insulation, surface absorption and predicted room conditions.

dB(A) · Rw dB · RT60 s
05

What does the material choice carry?

Embodied and whole-life carbon, with life-cycle modules and the study period made explicit.

kgCO₂e · kgCO₂e/m²
Life-cycle modules
06

What changes at the glazing?

Live glazing simulation with 6,000+ glass options and fully customisable assemblies. Compare thermal and optical properties.

U-value · SHGC · VT

Keep the alternatives
in the same frame.

Compare glazing and façade options across a shared set of assumptions. Review how carbon and occupied comfort vary across the option set before selecting a direction.

The basis of the study

Approachable inputs.
Serious analysis.

Rigorous building-physics methods and recognised assessment frameworks, with the assumptions and calculation context available for technical review.

Review the performance domains
Dynamic building performance simulation
Thermal behaviour and operational energy, with climate, geometry, construction and internal conditions in the study.
Radiance-based workflows
Daylight availability and visual comfort analysis.
Live glazing simulation
6,000+ glass options and fully customisable glazing assemblies. Review thermal and optical properties as you develop the design.
Thermal comfort
Comfort and overheating assessment, including PMV and TM52 outputs.
Room & building acoustics
Sound transmission, insulation, absorption and reverberation across walls, glazing, partitions, ceiling and floor.
Embodied & whole-life carbon
Carbon assessment based on ISO 14025, EN 15804 and RICS guidance. Review material and assembly impacts by life-cycle module and study period.

Carbon framework: RICS whole-life carbon assessment guidance ↗. ISO 14025 addresses Type III environmental declarations; EN 15804 provides the core product category rules for construction-product EPDs.

Open the evidence.

Go beyond a single rating. Inspect patterns, distributions and spatial results across the design.
