Calculators and worksheets for the subjects you study and the problems you meet in practice. Work through an example, try your own values, then test the same ideas in exam practice.
Ramp geometry calculator
Explore the space required by a chosen ramp rise and slope in a building-design study. Geometry alone does not establish accessibility compliance.
Open tool →FREE TOOLStair geometry calculator
Test a chosen integer riser count against floor-to-floor height. Explain why a straight flight with the upper floor as its final tread has one fewer going than risers.
Open tool →FREE TOOLLayered wall U value calculator
Build a wall thermal resistance from documented layer properties and surface films. Keep one-dimensional assembly performance separate from thermal bridging.
Open tool →FREE TOOLWindow to wall ratio calculator
Compare glazing proportions by elevation and calculate a correctly area-weighted whole-building ratio. Do not average elevation percentages without accounting for their wall areas.
Open tool →FREE TOOLFloor area efficiency calculator
Relate net usable floor area to the corresponding gross boundary. Record which area convention was used before comparing programme efficiency.
Open tool →Tools that connect the calculation to the concept
Each tool shows its method, units and assumptions, together with two worked examples. Example values are for learning; replace them with your own measurements or documented inputs. The related study links take you to the matching certification topic on Archi Conquer.
Worksheets run in your browser. We do not send entered measurements or report text to a calculation service. Where export is available, you choose when to save the file locally.
Check the boundary of the answer
A useful result starts with the right inputs and an appropriate method. These tools explain what is calculated and what the method leaves out. User-supplied criteria remain identified as supplied criteria; a calculation does not automatically approve equipment, certify an inspection or establish regulatory compliance.
