WHAT IS DAYLIGHT MODELLING?
Daylight modeling predicts various radiant and luminous quantities using daylight conditions derived from standard meteorological datasets. This advanced approach represents a significant evolution from traditional daylight analyses like daylight factor calculations and sun path diagrams.
Modern daylight modeling metrics now appear in building codes and guidelines, and evaluations have become essential in design practices nationwide. These simulations extract valuable information about a building's annual daylight performance, informing design decisions that enhance both sustainability and occupant comfort.
APPLICATIONS OF DAYLIGHT MODELING
Daylight modeling is valuable across all building types. Rating systems such as LEED v4.1 and v5, WELL Building Standard, and local green building codes are increasingly driving adoption of this approach. Many municipalities, counties, and regulatory bodies now request or require daylight assessment, analysis, and modeling, particularly for mixed-use and commercial developments.
The data from daylight modeling can also be efficiently repurposed for energy code compliance modeling, creating a comprehensive approach to building performance analysis that meets both federal and state requirements.
HOW IS DAYLIGHT MODELLING CONDUCTED?
We utilize simulation software built on Radiance, the industry-leading daylight simulation engine trusted by top design firms across the United States. Our simulations test your design under various environmental conditions (full sunlight, overcast, seasonal variations) using location-specific meteorological data from U.S. climate stations.
We report spatial daylight autonomy (sDA300/50%) and annual sunlight exposure (ASE1000,250) under IES LM-83, the metrics used by LEED v4.1 and v5 and by WELL. In LEED v4.1, an sDA of 40%, 55% or 75% earns 1, 2 or 3 points.
Our modeling process incorporates important contextual factors such as occupancy patterns, usage schedules, and building infrastructure to deliver accurate results specifically calibrated for American building standards and climate zones.
We integrate precise location-specific data including building orientation, height, surrounding structures, and regional climate conditions to generate accurate performance predictions tailored to your project's exact location within the U.S.
Once we've gathered and analyzed all necessary information, we can recommend customized modifications to optimize your building design. These enhancements ensure comfort year-round while maximizing natural sunlight and minimizing energy consumption that would otherwise be required for lighting and HVAC systems.
BENEFITS OF USING CLIMATE-BASED DAYLIGHT MODELING
The Climate-Based Daylight Modeling provides significantly more detailed information about light distribution and intensity compared to traditional daylight factors. This precision allows building designs to be optimized for natural light utilization. Key benefits include:
- Compare different design options with accurate visualizations
- Verify that proposed designs will provide adequate daylight
- Predict sources of potential glare, look at contrast ratios or balance of daylight within a space
- Indicate potential energy savings from electric lighting use
- Document daylighting code compliance and certification requirements
