• ​Comfort Diagnostics – Inspections and air balance consulting to resolve comfort complaints

 

• Mold/Moisture Diagnostics – Poor HVAC design/operation can create problems.  Roof and foundation issues are not always the source.

​​

• Utility Bill Audits (Energy and/or Error Auditing) - Often the best first step.  Utility bills can be audited for errors and energy procurement/source alternatives.  They can also be weather-normalized for more accurate comparison to prior years, and energy usage is benchmarked against peer facilities to forecast the possibilities. 

 

• Energy Star Building Certification – Please inquire about the many benefits.

 

• Facility Energy Surveys/Audits – Custom independent facility audits available to fit a wide budget range.  ASHRAE Level I, II, and III Audits are also available.  Proper energy analysis has a great return on investment and is catered to the needs of the client and their facility.  Big is not always best.  Not every building needs an ASHRAE Level 3 energy audit and calibrated energy model... the level of required analysis is influenced by two general factors:​​

  • Plans for the facility (timeframe, scope needs/limitations)

  • The condition of the facility (known energy/operational cost centers, comfort, or performance issues)

Some facilities may need nothing more than a utility bill audit, benchmarking, and possibly a quick, high-level building automation check (if controls exist).  Leverage the best energy path for your facility. ​

• Commercial Facility Inspections/Assessments for Appraisals & Acquisitions (Specialist) – Prior to purchasing a building or signing a major lease, it is recommended to audit existing facility energy usage and impending operational/maintenance costs.  Much more detail is provided in the areas of energy usage and mechanical systems (HVAC) than a typical inspection.  Note: a traditional commercial building inspection is still advisable to cover structural issues or maintenance issues that do not affect energy or the state of the HVAC/controls system, and Dohn Engineering, with its partnerships, can provide a full commercial building inspection if needed.  Specific to the energy/HVAC portion of the inspection, the scope will likely include benchmarking utility bills, inspecting controls/HVAC systems, noting install dates/preventative maintenance/reactive maintenance records to estimate life expectancy, identifying HVAC/lighting/controls system types and model specs while comparing to current standards of efficiency and determining obsolescence and upgradability (energy modeling may also be beneficial here depending on the client's needs).
