Building Owners/Managers:


MEP / HVAC engineering & design services are offered where energy consulting is not initially needed.  When energy consulting is initially needed, we specialize in independent energy analysis and facility diagnostics for building owners, we have no incentives to sell designs or equipment to our energy consulting clients due to our independent approach and would be happy to team with your preferred engineering designer or vendor during/after our analysis.  Design hand-offs are thorough and the extra time to ensure a smooth transition to a design engineer is completed at no cost.  


This approach also effectively places at least a second licensed Professional Engineer with detailed design experience in direct influence of the scope development for great results.  


If you do not have a preferred designer or vendor for any proposed solution, feel free to leverage our extensive knowledge and experience.  We would be happy to refer you to those we expect to best suit your needs.





We assist contractors, engineers, and architects with HVAC designs (in addition to our analysis and modeling services) and can tackle some of the most progressive system types.  Please inquire.  




Located near Louisville, KY, Dohn Engineering is not just a local MEP / HVAC engineering design firm and energy consultant.  We carry Professional Engineering licenses in multiple states to provide the flexibility needed for your projects.
