Glare Analysis

Glare Analysis is at the heart of what we do here at our Singapore ESD consultancy office of BroadTech Engineering.
Our team of experienced ESD consultants have demonstrated track records of successfully working on countless computational fluid dynamic (CFD) simulation for various major green building ratings such as Green Mark (Singapore), LEED (USA), Greenship (Indonesia), GBI (Malaysia), BREEAM (UK) and Green Star (Australia).
In addition to glare analysis, we are also able to conduct engineering simulation for various building-related environmental modeling analysis such as

 
Base on the post analysis of the engineering simulation results, our engineers will propose and monitor the end-to-end implementation of green building design concepts and techniques which are specifically tailored to the needs and challenges of your building engineering project.

What is Glare Analysis

Glare is a parameter used in modern building architectural design analysis techniques to predict and assess the occurrence of visual discomfort in occupants in the building. This is either caused by a sharp lighting contrast or higher than average luminous intensity
 
The prediction and quantification of the occurrence of visual glare due to daylight reflection can be easily achieved using

Why is Glare Analysis Important

In the building design process, the consideration of Glare as a design factor is an extremely important building design consideration. A professionally executed Glare analysis is able to give building design consultants, Green mark consultants as well as environmental consultant useful engineering insights, such as
 

1. Prediction of Glare Occurrence

Using computer engineering simulation, we are able to predict the mean hours of intolerable discomfort glare within a given day. In addition, we are also able to predict the occurrence of the visually discomforting glare at different specific time of the day.
This can be presented in the form of a color-coded image of the workspace to be analyzed, where it can visually highlight the different visual glare severity, such as 1. Imperceptible Glare, 2. Perceptible Glare, 3. Disturbing Glare, and Tolerable Glare).
 

2. Energy Planning

Base on the predicted average hours of natural daylight available annually, it allows green building consultants and designers to accurately use energy modeling to plan for the amount of artificial lighting needed and keep the energy consumption to a minimum.
 

3. Eliminate the Need for Luminance Analysis equipment

Advanced computational methods offer building engineers and designers a much more feasible method to accurately digitally simulate and examine the building interior spaces using the latest luminance based metrics to assess visual comfort and aspects of quality.
Such computational analysis allows engineers to carry out glare analysis without the need to deploy expensive luminance analysis equipment or handheld luminance meters.
 

Glare Metrics used for Glare Analysis

The various glare indices that we use includes
 

1. Daylight Glare Probability (DGP)

Daylight Glare Probability (DGP) is an image-based glare measurement metric used in computer-based glare simulation and analysis techniques.
It is commonly adopted by building designers and engineers to accurately predict the appearance of visual discomfort glare in daylit building interior spaces
