- Qu茅 te llevas: an interactive classifier to prioritize your upgrades by home type.
What passive design is (the no-nonsense version)
Passive design is not about gadgets; it is about your home needing far less energy to stay comfortable. The key: once you cut the demanda (the kWh your home needs), any system you install later works less and lasts longer.
The 3 decisions that rule your energy bill
Orientaci贸n
Decides how much free energy you get in winter and how hard the sun punishes you in summer.
Envolvente
Walls and windows. One bad pane of glass can ruin the best heating system.
Infiltraciones
The "shortcuts" your money escapes through: roller-shutter boxes, joints and badly sealed connections.
Renovation Classifier
Pick your home type and the upgrade you are considering, and we will tell you whether it is worth it. Illustrative assumption: rough savings percentages on heating and cooling, not a measurement of your home.

Verdict
Select your options to see the analysis.
Practical steps: start small
- Sketch your home: Mark where the sun hits in summer and in winter.
- Find the leaks: On a cold day, run your hand along joints and outlets.
- Pick 1 cheap fix: Weatherstripping, solar film or sealing shutter boxes.
Illustrative example: lower energy use with no building work
Picture a family in an apartment with a high annual bill. They prioritize three things: exterior blinds on the west side, sealed shutter boxes and solar film.
The result: savings and better comfort, before replacing a single machine.
