Engineering concepts with explicit assumptions, methods and limitations.
Lab investigates a question, not a winner
A concept study compares enclosure, autonomy or comfort approaches under explicit conditions. It begins with a specific question: how a layer changes heat transfer, what shading affects or what determines reserve duration. Without that question, a collection of numbers does not explain a decision, while an attractive visualisation can create unwarranted confidence.
Make the assumptions visible
A comparison defines geometry, materials, operating conditions and accounting boundaries. If one option has a different area or load, show the difference. Models omit parts of reality: a one-dimensional wall does not describe a corner, and average power does not reproduce pump starting. The exclusions determine which questions the result can still answer.
Separate numbers, diagrams and evidence
A calculation example demonstrates a method, a diagram explains relationships and a measurement records an observation under defined conditions. These forms should not be mixed. A Lab model cannot be described as a completed building or supplied with invented measurements. Claims about an actual property require separate evidence, permission to publish and sufficient context.
Transfer a conclusion cautiously
After reading, list the parameters shared with your case and those that differ. Consider sensitivity: would another humidity, area or load change the decision? If the main difference lies outside the model, a different method is needed. Knowledge explains the underlying physics and Studio helps define a project-specific assessment. Lab provides a basis for that question rather than construction approval. This makes the comparison useful without pretending it covers conditions it was never designed to represent.
