In 2020, Indonesia Stock Exchange selected ALTA Integra, through a beauty-contest process against other Indonesian consultants, to redesign the lighting, acoustics, and audio systems of its Main Hall, the trading-floor space that represents Indonesia's capital market to visitors, media, and global partners. The scope brought architectural lighting, room acoustics, and audio system design together as one integrated brief rather than three separate installations. The lighting design moved from stakeholder workshops and hand sketches through to a finalised concept, detailed specification, and a scenario-preview animation built in DIALux Evo so the client could evaluate how the space would look and feel before anything was installed. Tunable RGB ceiling fixtures let the Main Hall shift between thematic lighting states, red and white for Indonesian Independence Day, or a slow biomimicry-daylight sequence that echoes the natural progression from dawn to dusk, layered on top of an acoustically improved room. Through construction, the team ran periodic site inspections to check that installed light fixtures and audio components matched specification, coordinating closely with other trades so the finished ceiling and wall integrations read as one cohesive system. By the end of 2021, the lighting, audio, and acoustic work was commissioned and the refreshed Main Hall was ready for that year's Stock Trading Closing Ceremony, the exchange's most visible annual moment, presented at year-end to national leadership and broadcast as the public face of Indonesia's capital market.
