Thermal Resistance

Heat flows through a wall like current through resistors in series. Each layer's thermal resistance is its thickness over its conductivity; adding them gives the total R-value, and the heat flux is the temperature difference divided by it. Insulation, with very low conductivity, dominates the R-value — the steep temperature drop shows where it does its work.

Total R-value2.71 m²K/W
U-value0.37 W/m²K
Heat flux9.6 W/m²

Governing equation

Reading this result: The insulation layer carries the most thermal resistance, so the temperature falls most steeply across it. A total R-value of 2.71 m²K/W lets 9.6 W/m² flow for this 26°C difference.

Diet

Your carbon footprint is the sum of the greenhouse gases your lifestyle emits each year. The big levers are usually flying, driving, home energy, and diet. The global average is about 4.7 tonnes per person, but a livable-planet target is closer to 2 tonnes. Estimates use typical emission factors and will vary by region.

vs global avg1.8×
vs 2t target4.3× over

Governing equation

Reading this result: Diet is your single biggest slice at 2.5 t of the 8.7 t total, so that is where a cut moves the needle most — one long-haul flight can outweigh a whole year of driving.
