In this keynote presentation at Signify Innovation Day – Light the Future, Herwin Suryadi Gunawan represents ALTA Integra to discuss “Enabling Sustainable Building Performance in Indonesia: Lighting Role in LEED Certification.”

Held on 3 September 2026 at Sheraton Grand Jakarta Gandaria City, the event brought together professionals from architecture, lighting design, interior design, and engineering to explore lighting’s contribution to a more sustainable built environment.

Herwin’s presentation considers how lighting design can support energy performance, visual comfort, daylight integration, operational flexibility, and user experience. It places lighting within a coordinated building strategy, connecting design decisions with architecture, interior functions, facade response, commissioning, and long-term maintenance.

For architects, designers, consultants, developers, and building owners, the keynote offers a perspective on translating sustainability goals into practical lighting and building-performance considerations in Indonesia.

This speaking engagement reflects ALTA Integra’s human-centered approach to building performance: aligning architectural intent, technical criteria, environmental conditions, and the needs of people using a space.
