Building Noise & Vibration
NSV analyzes noise and vibration generated from building facilities and mechanical equipment to verify structural safety and operational usability.
Diagnostic
Objectives and
Expected Outcomes
-
1 Complaint Prevention
- Preventing resident complaints caused by noise and vibration generated during building facility operation
- Impact Assessment of Noise and Vibration
- Proactively mitigating economic losses related to reputational damage and compensation claims arising from complaints
-
2 Preliminary Impact Assessment
- Identifying root causes through document review and on-site investigation
- Evaluating vibration impacts on precision equipment by assessing structural suitability during the design of new facilities
- Predicting vibration and HVAC noise transmission between floors adjacent to mechanical or HVAC rooms
-
3 Optimal Solutions
- Designing optimal noise and vibration mitigation measures through simulation
- Prevention of Excessive or Insufficient Investment in Noise Control Measures Through Advance Prediction
Process Steps
SCROLL
Data Collection (Current Conditions)
Identify the building’s basic structure and equipment conditions to define the diagnostic targets.
- Review building section drawings (identify equipment locations and select evaluation targets)
- Measure existing noise and vibration levels of installed equipment
Review of Data and Standards
Review noise and vibration sources, related design documents, and regulatory standards.
- Identify noise and vibration sources (rotating equipment, loudspeakers, heavy machinery, footfall impact, piping, etc.)
- Review architectural and structural design drawings
Prediction (Simulation)
Analyze noise and vibration impacts from building equipment through simulation.
- Build a 3D analysis model (including excitation forces applied by equipment locations)
- Predict vibration and structure-borne noise impacts
- Perform analytical modeling and simulation
- Generate level contour maps
- Review simulation results
Evaluation of Prediction Results
Review and assess the overall noise and vibration impacts based on the simulation results.
- Evaluate simulation prediction results
Selection of Optimal Measures
Determine the most effective and economical mitigation plan.
- Derive the optimal solution
- Review with the client (considering cost-effectiveness and equipment operability)
- Finalize the mitigation plan
Design & Construction
Apply the selected mitigation measures to the design and implement them during construction.
Final Report
All analysis and review processes are compiled and presented in the final report.
