Building Commissioning

According to the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Guideline 0: “The Commissioning Process is a quality-oriented process for achieving, verifying, and documenting that the performance of facilities, systems, and assemblies meets defined objectives and criteria.” Our staff have been commissioning commercial facilities since 1992. We have commissioned projects across the country from 5,000 square foot bank branch offices to a LEED-certified 500,000 square foot hospital.

Heating, Ventilating, and Air-Conditioning (HVAC) Design

Our staff includes a Professional Engineer registered in Wisconsin, Minnesota, and Arizona. We can provide complete construction documents, drawings and specifications, for HVAC design projects in any of these States. We have provided HVAC designs for several LEED certified buildings that have consistently scored in the upper 88th percentile of Energy Star®, using less energy than 88% of similar buildings in their region. Our portfolio includes the design of ground loop heat pump systems, dedicated outdoor air systems, chilled and hot water systems, and variable air volume systems.

Energy Modeling

We have Trane Trace 700 energy modeling software in-house and can provide energy modeling for Green Globes certification, to achieve reduced interest rates from lenders, to secure 179D tax deductions, or to secure grants from local agencies. One of our recent energy models was completed for a 1.1-Million square foot pharmaceutical manufacturing facility.

Green Globes® Certification

Green Globes is a green building certification system owned by the Green Building Initiative (GBI) and has been active in the United States since 2004. Buildings certified under this system can achieve lower operating costs, reduced interest rates, and (in some locations) expedited permitting. Our staff have worked on over 100 Green Globes certified buildings and can show you how to get certified if you are constructing a new building or own an existing building.
