  2. List of lighting design software - Wikipedia

    en.wikipedia.org/wiki/List_of_Lighting_Design...

    This is a list of lighting design software for use in analyzing photometrics, BIM (Building Information Modeling), and 3D modeling. The software is typically used by importing the structural design via CAD files. Then lighting elements are inserted. And finally, the lighting objects are associated with a photometry via IES files.

  3. Lumen method - Wikipedia

    en.wikipedia.org/wiki/Lumen_method

    In lighting design, the lumen method, (also called zonal cavity method), is a simplified method to calculate the light level in a room.The method is a series of calculations that uses horizontal illuminance criteria to establish a uniform luminaire layout in a space.

  4. Architectural lighting design - Wikipedia

    en.wikipedia.org/wiki/Architectural_lighting_design

    The history of electric light is well documented, [11] and with the developments in lighting technology the profession of lighting developed alongside it. The development of high-efficiency, low-cost fluorescent lamps led to a reliance on electric light and a uniform blanket approach to lighting, but the energy crisis of the 1970s required more design consideration and reinvigorated the use of ...

  5. Daylight factor - Wikipedia

    en.wikipedia.org/wiki/Daylight_factor

    The design day for daylight factor calculations is based on the standard CIE overcast Sky for 21 September at 12:00pm, and where the Ground Ambient light level is 11921 Lux. CIE being the Commission Internationale de l´Eclairage, or International Commission on Illumination.

  6. Etendue - Wikipedia

    en.wikipedia.org/wiki/Etendue

    Etendue in free space. Consider a light source Σ, and a light detector S, both of which are extended surfaces (rather than differential elements), and which are separated by a medium of refractive index n that is perfectly transparent (shown). To compute the etendue of the system, one must consider the contribution of each point on the surface ...

  7. Luminous efficacy - Wikipedia

    en.wikipedia.org/wiki/Luminous_efficacy

    Luminous efficacy of radiation measures the fraction of electromagnetic power which is useful for lighting. It is obtained by dividing the luminous flux by the radiant flux. [4] Light wavelengths outside the visible spectrum reduce luminous efficacy, because they contribute to the radiant flux, while the luminous flux of such light is zero ...

  8. Light plot - Wikipedia

    en.wikipedia.org/wiki/Light_plot

    A light plot, lighting plot or just plot is a document like an architectural blueprint used specifically by theatrical lighting designers to illustrate and communicate the lighting design to the director, other designers and finally the Master Electrician and electrics crew.

  9. Building performance simulation - Wikipedia

    en.wikipedia.org/wiki/Building_performance...

    The objective of building performance simulation is the quantification of aspects of building performance which are relevant to the design, construction, operation and control of buildings. [1] Building performance simulation has various sub-domains; most prominent are thermal simulation, lighting simulation, acoustical simulation and air flow ...
