Analysis of Daylighting and Electric Lighting in Buildings

Does your workplace have the right amount of light for optimal working conditions? The amount of light in a workplace can greatly influence employee health and productivity.

A building’s lighting performance includes both electrical and solar light sources within a space and affects everything from comfort and safety, to energy costs and user productivity. Lighting is typically expected to be within a certain range of lumens (intensity) and quality for a given space and task. Ideal lighting design typically involves balancing light sources, costs, quality, and heat gains while avoiding issues of glare and over- or under-lit areas.

Typical uses include:

  • Lighting Level Analysis
  • Daylighting w/ Electric Lighting
  • Glare & Daylight Glare Probability

    • Extech Light Meter

    Measures - Illumination & Luminance

    The EA33 takes high intensity light measurements. Using the EA33's 50-reading memory, this light meter can store up to 50 measurements with either a relative or a real time clock stamp.

    Konica Minolta Luminance Meter

    Measures - Surface Illuminance

    Compact, lightweight, easy-to-use SLR luminance meters with a wide measuring range. 1/30 acceptance angle. Measuring range: 0.01 to 999,900 cd/m2. The user calibration function allows the meter to be calibrated to a user-selected standard instead of the preset Konica Minolta standard; this function can be used to standardize the response of several meters.

    SDL400 Light Meter

    Measures - Illumination & Lumiance

    The SDL400 records data on an SD card in Excel format. Wide range to 10,000Fc or 100kLux. Cosine and color-corrected measurements. Utilizes precision silicon photo diode and spectral response filter. Offset adjustment used for zero function to make relative measurements. Adjustable data sampling rate. Stores 99 readings manually and 20M readings via 2G SD card.

    Laser Distance Meter

    Measures: Distance

    Extech’s DT60M measures distance up to 196ft (60m). It can calculate area and volume and the integrated Pythagorean Theorem allows the user to take indirect measurements. Other features include continuous measurement with Min/Max distance tracking, 20 point memory, addition/subtraction of sequential readings, front or rear edge reference, and a Stakeout function. Large quad backlit LCD display and double molded housing. It also has a handy built-in bubble level and comes with a wrist strap.
