How can building performance be carried from design intent into completed spaces? This video presents ALTA Integra’s integrated approach to designing and verifying acoustics, lighting, and environmental performance.

The process begins with the Owner’s Project Requirements (OPR): understanding the owner’s vision, functional goals, site conditions, and project constraints. These requirements inform the Basis of Design (BOD), which establishes performance targets, design strategies, and coordination with architecture and mechanical, electrical, and plumbing systems.

The video follows the workflow through detailed calculations, modeling, design optimization, technical drawings, and specifications. It also explains the role of tender documentation, technical evaluation of bidders’ submissions, material reviews, site inspections, and coordination during construction.

The final stages focus on performance verification through testing, adjustment, and calibration against the agreed design criteria, followed by an assessment of occupant satisfaction.

For architects, developers, engineers, building owners, and project managers, the video offers a clear view of how measurable requirements and multidisciplinary coordination can support the delivery and evaluation of building performance.

Part of the Herwin Gunawan Work video library, this entry reflects ALTA Integra’s evidence-led, human-centered approach to connecting design decisions with real user experience.
