House of Worship
ALTA Integra's house of worship practice covers Worship acoustics, speech intelligibility, daylighting, and AV for churches, mosques, temples, and sacred heritage.
Featured Project
A recent example is
Gereja Katedral Jakarta (Jakarta, 2025) — one entry in ALTA Integra's wider
projects portfolio of 51+ completed buildings.
Why It Matters
Public venues put acoustics and lighting in direct competition for the same sightlines — a broadcast camera position, a speaker cluster, and an emergency-lighting run all want the same ceiling void. Getting the sequencing wrong means a beautiful rendering that a contractor cannot actually build without cutting one discipline's performance to save another's.
Disciplines Involved
This work typically draws on ALTA Integra's
acoustic,
lighting, and
sustainability disciplines together, coordinated as one practice rather than separate vendor scopes signed off independently. See the full
integrated engineering services list for the complete discipline range, including audiovisual and IT systems where a project's scope calls for them.
Methodology
Preliminary study and design criteria — a review of function, occupancy, and adjacencies, setting measurable performance targets before design decisions lock in.
Modelling and simulation — predicting performance before construction, so trade-offs are visible on screen rather than discovered on site.
Cross-disciplinary coordination — resolving conflicts between disciplines during design, not after each vendor has already signed off separately.
Measurement and commissioning — verifying installed performance with real instruments against the original targets, not just a visual walkthrough.
Standards
Projects of this type follow recognised international practice, including guidance from the
Illuminating Engineering Society, alongside Indonesian SNI requirements and ALTA Integra's standard measurement-and-commissioning methodology applied consistently across every building type.
Within Public Buildings and Spaces
House of Worship sits inside ALTA Integra's
Public Buildings and Spaces sector group, alongside related building types such as
Sport Stadium,
Cultural and Performing Arts,
Museum and Gallery. Explore
building physics insights for the research and site observations behind this work.
Tools and Verification
Design decisions for this building type are modelled before construction, not guessed at — acoustic performance in tools such as CATT-Acoustic and EASE, sound insulation in INSUL and SonArchitect, and lighting performance in DIALux Evo, depending on which disciplines the project calls for. Installed performance is then verified on site with real instruments — NTi XL2/XL3/M2210 for acoustic measurement, UPRtek and Sekonic meters for lighting — rather than assumed from the design model alone.
Track Record
ALTA Integra has practiced across acoustic, lighting, audiovisual, IT, and sustainability disciplines since 2010, delivering more than 250 completed projects over 15+ years and holding 9+ professional credentials as of 2026. That track record spans every building type in the
sectors list, not only the ones with a named case study on this page.
