Engineering Economics, Inc. (EEI) specializes in building commissioning and has become one of the nation's leading Commissioning Authorities.  A vocal champion of the commissioning process, EEI was a founding member of the Building Commissioning Association (BCA) and won the nation's first official "commissioning" project in 1991 -- the Fred Hutchinson Cancer Research Center, a multi-city block medical research complex in Seattle, Washington.  Today, EEI is an extremely successful and trusted Commissioning Authority, working for some of the nation's leading institutions and Fortune 500 companies. 

With a physical presence in 11 states and nearly 80% of the firm's revenue derived from commissioning services, EEI is considered by owners to be a highly experienced, independent third-party commissioning firm.  To date, EEI has provided its clients with commissioning services on more than 170 million square feet with total construction values in excess of $31 billion over this 20-year period.  The firm has provided commissioning services for nearly every type of facility as shown in the Projects section of this website. 

The Case for Building Commissioning

According to a 2009 study conducted by Evan Mills of Lawrence Berkeley National Laboratory and sponsored by the California Energy Commission, commissioning is “arguably the single-most cost-effective strategy for reducing energy, costs and greenhouse-gas emissions in buildings today”.  The study found that new building commissioning typically reduces energy usage by 13%, pays for itself in 4.2 years (excluding non-energy savings) and generates a 23% cash-on-cash return on investment.  Significant non-energy benefits substantially reduce this payback period to between 1 and 2 years, and subsequently increase the return on investment.  This has certainly been the experience of our firm and its clients.

Building commissioning maximizes the operational efficiency of facility systems.  The commissioning process:

  • Ensures fully-operational critical building systems
  • Lowers operating & maintenance costs
  • Increases system energy efficiency
  • Improves indoor air quality
  • Reduces the risk of "sick building" syndrome
  • Decreases occupant complaints and enhances productivity
  • Provides better environmental control
  • Reduces maintenance/troubleshooting issues
  • Ensures well-trained facility personnel
  • Provides benchmarks for future performance evaluations
  • Reduces life-cycle costs of the facility
  • Improves owner return on investment
