Daylight Analysis

Daylight Analysis is at the core of what our ESD consultants do here at our Singapore offices here at BroadTech Engineering.
It involves the use of computational engineering simulation to determine the extent to which natural external daylight has penetrated into a specific building interior spaces through the openings, such as windows, ventilation vents, and glass facades.

Using daylight analysis, it allows building design consultants, architects, environmental consultants, and designers to enhance the operational effectiveness as well as the energy efficiency of building layout and equipment (for example ensuring the efficient operation of photosensors by optimizing its placement positioning).

Through the use of daylight analysis and environmental modeling tools, it offers building designers and Green building consultants a scientific and predictable way to optimize building layout design to facilitates the maximum possible distribution of natural daylight rays throughout the building where appropriate. This, therefore, helps to keep the building energy usage to a minimal as the need for artificial lighting is significantly reduced.

Comprehensive Building Design Analysis

During the early building design phase, daylight analysis can be used to perform feasibility evaluation in conjunction with other complementary ESD simulation studies in the BIM, such as Sun’s Solar load analysis, Thermal Comfort Analysis, Sun path analysis and shadow studies (for formulation of shading design and strategies)
This helps ESD consultancy companies to provide a comprehensive design analysis of conceptual interior design of rooms, such as their overall layout, shape, aperture, and size dimension

Daylighting metrics

At the end of the daylight analysis, you will be presented with a post-analysis report which shows you the specific numerical values of the daylighting measurement.

Using Daylight Analysis to Evaluate Daylighting Performance to Ensure Green Mark Compliance

Our Daylight analysis team is also able to accurately simulate and compute the ambient daylighting available for individual rooms and layouts designed into your building interior space.
Base on the daylight analysis report, you will have an insight into the natural brightness level for each specific workspace of interest and how it measure up to the required daylighting levels at specific times of the day (fall equinox at 9:00 am and 3:00 pm) as stipulated by the Green Mark requirements.

Benefits of Performing Daylight Analysis

Performing an in-depth daylighting analysis using our simulation metrics tools can help you to answer some fundamental questions such as:

1. Building Design Optimization

Optimization of the building design parameters to maximize the entrance of natural light. This can include parameters, such as Room layout, glazing properties of building construction material, a design of shading features, and placement of window in relation to the direction of the sun’s movement.
Note that ideally, the desired daylight comes from the ambient sky, not directly from the sun.
Because the daylight originating from the sun is a form of radiation transmission (shortwave, within the visible spectrum), the sun’s solar radiation analysis will allow you to have a sense of the quantity of natural sunlight that each specific facet of the building is able to draw in.

2. Determining Adequate level of Indoor Illuminance

Daylight analysis enables the accurate quantification of light (measured in Lux or Footcandles) falling onto the indoor surface.
This helps to ensure an adequate amount of light levels is entering the building to produce a sufficient level of natural illumination for the performance of specific daily tasks in an indoor space environment. This analysis of daylighting performance in buildings can be performed using Revit

3. Evaluation of Energy Savings from Replacement of Artificial Light

Daylight analysis can be used to perform a precise measurement and calculation of how much percentage of the artificial light that the natural daylight can replace and offset for a specific workspace area.
This helps in energy modeling efforts by helping to predict the energy savings by using useful measurement metrics such as Daylight autonomy, UDI, Daysim, and Radiance.

4. Prevent Occurrence of Glare

Daylight analysis enables the accurate visual simulation of the natural light distribution to ensure there is no occurrence of glare from the sunlight.
To avoid visual glare from penetration of direct suns ray, daylight analysis can be used to measure the variation in the light reflecting off a material surface which has a specific reflective property measured either by luminance values in cd/m2, or another glare metric such as DGP.

Ensure Visual Comfort through Glare Elimination

Daylight analysis and simulation helps to eliminate issues of unwanted glare reflections from sunlight. This Glare analysis enables you to accurately evaluate and ensure the overall Visual comfort of the occupants in the building interior space.
