How it works

It stops radiation before it passes through the glass using eaves, slats, blinds or other elements adjusted to each orientation.

It acts on the shape and envelope to moderate outdoor conditions before resorting to facilities. Measurements should work together, not as isolated pieces.

When does it make sense?

  • In new construction or rehabilitation of the envelope
  • After analyzing climate, orientation, use and humidity risks
  • When it is possible to check the designed detail and execution

How to apply it

  1. 1

    Defining what need resolves "external solar protection" and establishing a starting situation.

  2. 2

    Compare alternatives and adapt design to climate, use, regulation, affected people and available resources.

  3. 3

    Apply with clear responsibilities, check the actual result and correct unwanted effects.

Potential benefits

Lower thermal demand

Increased comfort and resilience

Lower equipment dependency

Limitations and precautions

  • The result depends on context, design, execution and how it is used and maintained.
  • A poorly adapted passive solution can cause overheating, humidity or poor air quality.
  • Performance depends on both implementation and concept.
