Measuring daylight levels can be a time-consuming process in large buildings. Measurements are taken on a 10-foot by 10-foot grid, with four measurement points for each 10 ft2 section. Taking and recording each measurement takes about 30 seconds—not including setting up the grid—for a total of about two minutes per grid section.

For Option 3, take daylight measurements with a hand-held light meter and record the values on a 10 foot x10 foot grid plan. Enter square footage of regularly occupied areas, and total area of regularly occupied space that meet the daylight requirements i

For Option 3, take daylight measurements with a hand-held light meter and record the values on a 10 foot x10 foot grid plan. Enter square footage of regularly occupied areas, and total area of regularly occupied space that meet the daylight requirements in the LEED Submittal Template. Upload all required supporting documents to LEED Online.

During the value engineering process, ensure that components critical to the daylight design, such as high-performance glazing and internal shading devices, are not removed from the project.

Measurement is a low-cost compliance method but may not help to optimize daylight during the design phase. An optimized daylight design can cut down substantially on lighting costs over the long run.

Measurement can account for complex daylight designs but does not help inform the design process. It can only confirm compliance once the space has already been constructed.  At that late phase, it may be too costly to make design changes to bring more floor area into compliance.

Measuring daylighting with handheld light meters can be time-consuming for large areas. Also, you are likely to need to defer this credit to the construction phase LEED submittal so that accurate light readings can be taken with interior walls in place.
