Parking Garage Ventilation Optimization

Objective:
To ensure effective air circulation and removal of vehicle exhaust gases (CO, NOx) in an underground parking garage.

we simulated airflow patterns, pollutant dispersion, and ventilation efficiency under various vehicle load scenarios

This allowed us to

Identify stagnant air zones and optimized jet fan placement
Reduce CO concentration below threshold levels in all occupied zones

Impact:
Validated compliance with safety codes, ensuring occupant safety and cost-effective ventilation system performance.

Energy Sensitivity Analysis of Insulated Building Walls

Objective:
To Minimize heat gain through building walls under real weather conditions.

A full-day simulation analyzed energy transfer through a wall assembly composed of two insulation layers and a concrete core. Wind, temperature, and solar radiation were included. Material types and thicknesses were systematically varied.

This allowed us to:

Identify optimal material configuration
Achieve the lowest energy entry into the building
Demonstrate strong sensitivity to outer insulation properties

Impact:
Informed material selection for improved thermal performance and energy efficiency in building envelopes.

Data Center Cooling Optimization

Objective:
To Enhance thermal management and airflow efficiency in a high-density data center.

Approach:
temperature distribution, airflow paths, and rack inlet temperatures were analyzed. Various cooling strategies (hot aisle/cold aisle, CRAC positioning, and airflow containment) were tested.

Results:

Reduced hotspot occurrence by 75%
Improved cold air delivery to critical racks
Lowered overall cooling energy demand by 22%

Impact:
Enabled safer operating temperatures, improved reliability, and significant energy cost savings.

Stratum Ventilation in Office Space

Objective:
Optimize air distribution and comfort in an open-plan office using stratum ventilation.

Approach:
CFD simulations analyzed the impact of varying air change rates (ACH) and different supply port locations. Key performance indicators included airflow distribution, CO₂ removal, and thermal comfort at occupant level.

Results:

Identified optimal port positions for uniform air coverage
Improved ventilation effectiveness by 40%
Maintained thermal comfort with minimal energy use
Achieved lower CO₂ levels in breathing zone

Impact:
Demonstrated that smart placement and control of supply ports significantly enhance air quality and energy efficiency in office environments.

Generator Room Ventilation Analysis

Objective:
Ensure safe heat removal and air quality in a generator room under peak operating load.

Approach:
CFD simulations evaluated airflow paths, temperature distribution, and hot air buildup. Multiple exhaust and intake configurations were tested under different generator load scenarios.

Results:

Reduced peak room temperature by 18°C
Eliminated hot spots around generators
Optimized fan and louver placement for balanced airflow

Impact:
Improved equipment reliability, safety, and compliance with thermal management standards.
