This video presents the testing and evaluation of lighting scenarios at Jakarta Cathedral, exploring how architectural lighting can support visual comfort, reveal architectural features, and contribute to the spiritual and liturgical experience of the space.

The ALTA Integra and Jakarta Cathedral teams examine the relationship between lighting design, spatial perception, and the experience of sacred architecture. The evaluation considers how different lighting scenarios can support the cathedral’s sacred atmosphere and liturgical function while responding to the needs of people using the space.

For architects, lighting designers, consultants, and teams responsible for places of worship, the video offers a perspective on evaluating lighting beyond visual appearance. It connects design intent with lighting performance, human comfort, and the role of light in worship and contemplation.

Part of the Herwin Gunawan Work video library, this video reflects ALTA Integra’s evidence-led approach to human-centered building performance, connecting technical considerations with architectural context and user experience.
