Acoustic Design for an Alberta Modern Indigenous Governance Facility

HGC Noise Vibration Acoustics was retained to provide comprehensive acoustical engineering services for the new Kainai Nation (Blood Tribe) Administration Building—a two-storey, ~5,300 m² multi-use civic facility that will bring together 13 administrative and community-serving departments under one roof.

HGC evaluated all major program areas, developed project-specific noise and reverberation criteria, and completed detailed acoustic modelling—most notably 3D-assisted simulation for the unusually shaped Council Chambers, one of the building’s acoustically critical spaces.

The design is oriented toward sacred landmarks such as Chief Mountain and the Belly Buttes, and draws form from the Sundance Lodge, grounding the building in cultural significance. HGC’s acoustical guidance ensured that the sonic environment supports the project’s core values of cultural representation, accessibility, governance, and community well-being.

Acoustic Challenges of the Indigenous Governance and Community Service Building

The Blood Tribe – Kainai building includes a broad range of spaces with distinct acoustic performance requirements:

• Circulation Areas / Atrium / Lobbies
• General Offices and Open-Plan Work Areas
• Conference Rooms and Boardrooms
• Private Offices and Small Meeting Rooms
• Council Chambers
• Auditorium
• AV Media Production Studio
• Elders’ Room and Classroom
• Wellness & Fitness Centre
• Bank
• Post Office
• Cafeteria and Kitchen

These program elements required coordinated approaches to noise control, sound isolation, and reverberation management to support speech intelligibility, privacy, cultural gatherings, governance proceedings, and everyday administrative functions.

Indoor Noise Criteria –
Establishing Acceptable Background Sound Levels

HGC established ASHRAE-aligned Noise Criterion (NC) targets for all occupied areas. Given the building’s functions—including governance chambers, boardrooms, instructional spaces, and a media production studio—project priorities included:

• Control of HVAC-generated background noise
• Achieving comfortable conversational levels in small and large rooms
• Balancing sound masking and speech privacy in open-plan work areas

Appropriately calibrated sound masking will assist with areas handling confidential governance or administrative discussions.

Reverberation Modelling and Treatment Strategy –
3D Analysis of Critical Spaces

Reverberation control is central to speech clarity, and comfort in public buildings. While smaller rooms benefited from the use of NRC 0.70+ acoustic ceiling tiles, large-volume and architecturally complex spaces required advanced modelling, including customized acoustical control strategies for the Council Chambers, which feature non-parallel walls and sloped surfaces.

HGC completed 3D reverberation modelling using architectural geometry and material specifications provided by the design team. Key recommendations included the addition, redistribution, or modification of acoustic treatments in:

• The main atrium and lobby
• Circulation corridors
• The auditorium
• The cafeteria and kitchen
• The bank and community service areas
• Boardrooms
• The Council Chambers
