KJWW focuses on providing clients with options-oriented solutions and offers market-focused leadership and expertise in the unique demands, code compliance, and trends in different industry sectors. The Challenge Ensuring Employee Comfort and Safety While Minimizing Costs KJWW was hired to design a heating and ventilating system for a new 400,000-square-foot manufacturing facility that its client was adding to an existing building. The client wanted its employees working on the assembly lines located in the core of the new building to have a comfortable environment in terms of temperatures. This was challenging for two reasons: 1. Various overhead doors would be located around the perimeter of the new structure, and during the winter months would introduce very cold gusts of air into the facility when opened. 2. The client required an energy-efficient ventilation solution to meet sustainability and project budget initiatives. To address these concerns and identify the best possible solution, KJWW recognized that they needed to analyze the temperature variance in the building under different conditions. The team decided to hire an outside firm to conduct a computational fluid dynamics (CFD) study to gain confidence in the chosen strategy prior to finalizing detailed design documentation and equipment procurement. Since the client requires three bids for work, the team sent RFPs to different vendors, including Rand Simulation. "We evaluated different companies that could provide the CFD analysis, looking for a firm that had extensive expertise in this area and could meet the tight schedule requirements for the project in a cost-efficient manner," said Steve Mumm, a senior engineer at KJWW. "We needed to complete the full analysis with iterations within one month. Rand Simulation was the best fit for this project's needs." Thermal profiles around the roll-up doors
