Study Notes
Artificial Illumination and Daylighting
- Lighting is crucial in architecture, affecting space perception, material textures, and occupant comfort.
- Artificial lighting is often planned later in the design process, potentially compromising ideal design.
- "Design" combines science, art, and human factors for useful lighting in spaces.
- Lighting design incorporates scientific principles, standards, and aesthetic, cultural, and human elements.
- Basic lighting analysis involves understanding energy-efficient lighting options for homes/offices.
Lighting Fundamentals
- Understanding basic lighting principles and terms is essential.
Light Quantity
- Illumination is the distribution of light on a horizontal surface.
- The goal of lighting is to produce illumination.
- Lumen is a measure of visible light energy.
- A 100-watt incandescent lamp roughly produces 1600 lumens.
- Watts measure energy consumption, and are part of the calculation for electricity bills.
Quantity of Illumination
- Lumen is the most common measure of light output/luminous flux.
- Light sources are labeled with lumen outputs (e.g., a 40-watt fluorescent lamp may have 3050 lumens).
- Lamp output decreases over time (lumen depreciation).
- Illuminance: Light intensity measured on a plane, in units of footcandles (work plane lumens per square foot).
- Lux: Metric unit for illuminance (lumens per square meter); 10.764 lux = 1 footcandle.
Brightness
- Luminance: Measures light "leaving" a surface in a particular direction (consideration of illuminance and surface reflectance).
Light Quality
- Glare: Excessive brightness from a light source that hinders the visibility of desired objects.
- Color Temperature: Measures light color, with warmer colors (yellow-red) being lower Kelvin values and cooler colors (blue-green) being higher Kelvin values. (e.g., 2700–3000 K is warm, 3600–5500 K is cool).
- Color Rendition (CRI): Measures a light source's ability to reproduce colors similarly to sunlight (a 1-100 scale; 80 or higher is acceptable for most indoor applications).
Ambient Lighting
- Provides general illumination for daily activities in indoor and outdoor spaces.
Task Lighting
- Provides focused illumination for specific tasks needing more light.
Accent Lighting
- Draws attention to special features and enhances aesthetics in indoor or outdoor environments.
Energy Consumption and Efficacy
- Efficacy is the ratio of light output (lumens) to energy consumption (watts). Higher lumens/watt ratio = higher efficacy.
Lighting Design Principles
- Focus on rooms used most frequently.
- Replace existing fixtures with LED bulbs for increased impact.
- Use layered lighting (ambient, task, accent).
- Consider the room's function and form.
- Use concealed light sources.
- Limit the number of light sources to reduce complexity.
- Employ lighting control and flexibility (sensors, dimmers, remote controls).
Lighting Control and Flexibility
- Lighting controls (sensors, automatic responses) can be beneficial for optimizing energy efficiency and usability.
Cost of Implementation
- Equipment, installation, design, maintenance, energy, and environmental factors are all part of a lighting system.
Installation
- Installation requires licensed electricians or similar professionals in many contexts.
Maintenance
- Proper maintenance of lighting systems may minimize costs by using long-lasting products (e.g., LED).
