Lighting in buildings and public facilities must balance energy efficiency with a comfortable environment for users. Developing a lighting control system to meet these goals required application design and evaluation. Publicly available information does not identify the specific challenges in existing operations or the evaluation criteria.

The goal is to support the development of a lighting control system that balances energy efficiency with a comfortable lighting environment by designing and evaluating a Windows application.

SMILE was responsible for the design and evaluation of a Windows application built with C#. Because the available information does not confirm the scope of implementation or SMILE’s involvement in deployment and operations, this article focuses solely on design and evaluation.

The proposed approach is to define the lighting control system's usage requirements, incorporate them into the design of the C# Windows application, and establish evaluation criteria for each requirement. Linking requirements, design, and evaluation provides a clear basis for assessing the application.

A key consideration for a lighting control application is whether its usage requirements, design, and evaluation results align. We propose defining usage scenarios and evaluation criteria, reviewing the design against them, and checking the results for each scenario.

The design and evaluation work will help create an application tailored to the lighting control needs of buildings and public facilities. The system aims to reduce energy use while providing a comfortable lighting environment for occupants.

One possible collaboration model is for the customer in Japan to provide the requirements and confirm the evaluation criteria, while SMILE handles application design and evaluation within the agreed scope. Both parties would then review any outstanding questions and the evaluation results before moving on to the next phase.

SMILE designed and evaluated a C# Windows application for a lighting control system used in buildings and public facilities. The project aimed to balance energy efficiency with a comfortable lighting environment, and SMILE supported its development through application design and evaluation.
