The Greenbusch Group specializes in 3D computer modeling of sound and noise vibration and conditions. Ground source geothermal heat warms Seattle's newest fire station.

Modeling & Analysis


  • Used for industrial facilities, construction sites, and various environmental noise projects
  • Can be built from client CAD drawings
  • Accounts for weather patterns, foliage, topography, ground conditions, screening, and reflections from buildings or walls
  • Models exterior and interior noise
  • 2-D and 3-D perspectives, great for community meetings and technical reports

  • 3-D models evaluate sound systems and acoustics before the building is built
  • Evaluate wall finishes and room shapes once the building is completed
  • Used to predict speech intelligibility for life safety


  • Predicts sound isolation properties of wall, ceiling, and window constructions
  • Quantifies expected reductions from resilient floor finishes and underlayments
  • Predicts interior sound levels from rainfall base on the roof-ceiling type
