Signolog advocates for the approach that facade, signage, and directional design should not only be about aesthetics but also be grounded in scientific principles and communication theories. This perspective reveals that a building's facade is not just an external image but also an effective communication tool with its interior and users. Here are some key considerations:

Aesthetic and Harmony: The facade should harmonize with the overall building design, presenting a cohesive aesthetic. There should be a balance and harmony among colors, materials, and forms.

Functionality and Communication: The facade should cater to the needs and usage of the building's interior. Additionally, it should establish effective communication with the building's occupants and its surroundings.

Durability and Security: Facade materials should be resistant to weather conditions, environmental impacts, and the wear and tear of time. Features ensuring security should also be considered.

Energy Efficiency: Modern facade systems should be designed to provide energy efficiency. Proper insulation can reduce energy costs.

Sustainability: Using eco-friendly materials and adopting sustainable construction practices are integral to modern facade design.
