Daylight Analysis & Modeling

Daylight simulation is a computer-based tool used to evaluate and analyze the amount and distribution of natural light in a building. This simulation takes into account the position of the sun and the surrounding environment, as well as the building's design, to accurately predict the amount of daylight that enters the interior spaces of a building.

The simulation allows investors to optimize the use of natural light in a building, reducing the need for artificial lighting and promoting energy efficiency. It also helps to ensure that a building's indoor environment quality is enhanced, with improved visual comfort and reduced glare.

Daylight simulation is used in the early stages of building design to evaluate and refine design concepts and make informed decisions about building orientation, window size and placement, shading elements, and other design factors that impact the amount of natural light in a building. The results of the simulation can also be used to optimize the energy performance of a building and to ensure that it complies with relevant codes and standards.

Daylight Simulation has several advantages in the design and evaluation of buildings:

  1. Energy Savings: Daylight simulation can help to optimize the use of natural light in buildings, reducing the need for artificial lighting and resulting in energy savings.

  2. Improved Indoor Environment Quality: By exposing building occupants to natural light, daylight simulation can improve the overall indoor environmental quality, promoting well-being and comfort.

  3. Sustainable Design: Daylight simulation can help designers create buildings that are more sustainable and environmentally friendly, reducing their carbon footprint and helping to protect the planet.

  4. Cost-effective Design: Daylight simulation can assist in reducing construction costs by allowing designers to optimize the use of natural light and reduce the need for artificial lighting, saving on materials and labor costs.

  5. Better Building Performance: Daylight simulation can help to ensure that buildings perform better, with improved energy efficiency and indoor environment quality, leading to increased occupant satisfaction and productivity.

  6. Compliance with Codes and Standards: Daylight simulation can assist in ensuring that buildings meet relevant codes and standards, such as LEED or ASHRAE, which specify requirements for energy efficiency and indoor environment quality.

Sun, Shadow, and Glare Analysis: Sun, shadow, and glare analysis is a tool used in daylight simulation to evaluate the impact of the sun on a building's interior and exterior spaces. This analysis takes into account the position of the sun at different times of the day and year and the resulting shadows and glare levels on interior spaces and surfaces.

Shading Elements-Based Design: Shading elements-based design is a daylight design approach that focuses on the use of shading elements, such as louvers, brise-soleil, or overhangs, to control the amount of direct sunlight entering a building. This approach helps to mitigate the effects of glare and overheating, improving the indoor environment quality.

Facade/Solar Radiation Effect: The facade or solar radiation effect refers to the impact that a building's facade has on the amount of sunlight entering the building and the resulting heat gain. This effect can be evaluated through daylight simulation and is an important consideration in the design of sustainable and energy-efficient buildings.
