Ambiance Architecturale et Urbaine

Partie II: Initiation à la dimension physique des ambiances architecturales et urbaines

• Ambiance: A characteristic, often intangible quality of a space, influenced by multiple factors, including physical signals
• Physical dimension of ambiance: The measurable and quantifiable elements that contribute to a space's atmosphere.
• Key factors influencing ambiance: Physical signals (light, temperature, sound, odors, air movement), the physical support (material or spatial context), perceptions (objective and subjective), and social interactions and experiences.
• Physical signals generating ambiance: Light, thermal flux, sound, odors, and air movement.
• Signal definition: The physical manifestation of an ambiance phenomenon, such as a sound, light, or thermal flow. This element is quantifiable and measurable.

Introduction

• Describing a space's ambiance requires a detailed account of the factors influencing it.
• Ambiance is a complex and multifaceted concept involving both tangible and intangible aspects
• The study of physical ambiance focuses on measurable elements such as light, temperature, sound, odors, and air movement, impacting how we experience and perceive a space.
• The combination of the four factors (signals, physical structure, perception, and experiences) creates a holistic ambiance.

Le Soleil (ensoleillement), principale source du signal

• The sun is a major source of light and thermal energy.
• Solar radiation spectrum: Plays a role in both light and thermal aspects of ambiance.
• Solar position: Determines the angle of solar radiation hitting a surface, influencing both intensity and amount
• Solar altitude (H): Angle between solar rays and the horizontal plane.
• Solar azimuth (A): Angle between the solar rays and the north-south line.

Le Rayonnement et l'énergie solaire reçue

• Solar energy: Partially absorbed, reflected, and diffused by the atmosphere.
• Direct radiation: Sunlight directly striking a surface.
• Diffuse radiation: Sunlight scattered by the atmosphere.
• Global solar radiation: Combined direct and diffuse radiation.
• Intensity of solar radiation is related to factors like atmospheric turbidity and the angle of incidence of solar rays on a surface.

Ce quiz explore la dimension physique des ambiances architecturales et urbaines. Il aborde les facteurs influençant l'ambiance, notamment les signaux physiques tels que la lumière et les sons. Les étudiants découvriront comment ces éléments mesurables contribuent à l'atmosphère d'un espace.
