Outline and Purpose of the Course This course covers basic physical characteristics of lighting, color, and acoustic, as well as their analysis and prediction methods that are required during architectural design process to achieve safe and comfortable environment. The course will also cover the psychological and physiological effects of such environmental factors and their evaluation methods.
Course Goals Students will learn the fundamentals relating to lighting, color, and acoustics that need to be considered during architectural design process and their application. Of the learning and education objectives listed by the department: B. Expertise and Basic Knowledge, B4. An understanding of the environmental side of architecture.
Schedule and Contents (1) Vision and Photometry- 2 classes:
These lectures will consider how the human visual system responds to the light environment, explain how to derive photometric quantities (the basis of light measurement), and provide relevant definitions. The lectures will cover the structure of the eye and retina, sensation of light through rods and cones, adaptation of the eye to the light environment, spectral luminous efficiency, radiometric quantities and photometric quantities, luminous flux, light intensity, illuminance, and luminance.
(2) Architectural Lighting, Calculation of direct illuminance - 2 classes:
These lectures will explain how to measure illuminance, the basis of architectural lighting, and its application in architectural lighting. The lectures will cover computation of the direct illuminance by a point light source, reflection and transmission of light, uniform diffusion, direct illuminance by a surface light source, and configuration factors.
(3) Daylighting, 1 class:
The lecture will explain how to obtain a position of the sun and the sun shadow region of a building.
(4) Color System Basics - 2 classes:
Beginning with the mechanism through which people perceive color, this lecture will explain the color system for quantitative descriptions of colors. This lecture will cover the mechanism of color vision, the three attributes of color, the Munsell color system, and the CIE XYZ color system.
(5) The Nature of Sound and its Physiological and Psychological Effects - 3 classes:
Radiated acoustical wave from a source is affected by various objects that exists along its propagation path, until it reaches human ears and is perceived as sound. These lectures will outline the nature of sound propagation, the function of the human auditory system, and physiological and psychological human responses to sound.
(6) The Physics of Vibration and Sound: Foundations of Acoustic Design - 4 classes:
These lectures will explain basic topics relating to the physics of vibration and sound and the foundation of all acoustic design with the objective of creating a comfortable acoustic environment within and outside of building structure. In addition, wave propagation theory, physical indices of sound, and basic theory for acoustic design will be outlined.
(7) Feedback - 1 class:
Assessment of students' understanding and application of course material.
Evaluation Methods and Policy Evaluation will be based on final examination scores.
Course Requirements None
Study outside of Class (preparation and review) Students are required to prepare by reading textbook sections prior to each lecture.
Additionally, students shall deepen their understanding by reviewing material covered after each lecture and ask their instructors about any points that are unclear.
