The 3fficient Story

Doug Poffinbarger started 3fficient to help customers recapture tremendous inefficiencies in the use and delivery of energy and other utilities.

As a Director of Sustainable Cities for NRG, the largest independent power producer in the Americas, Doug noticed that energy architecture is woefully inefficient, leaving significant demand reduction and energy savings missed by energy users large and small.  He founded 3fficient to solve this problem and make it easy for customers to recoup significant utility, maintenance and tax savings through a transparent, holistic delivery of smart energy solutions paid from savings.

Today, 3fficient has grown into a leading clean tech company with game changing products and services serving several continents.  3fficient has helped develop smart meters that monitor the energy pulse of every circuit in buildings, invisible window insulation that is 300% better than plastic tints, fully wireless building automation that affords “peel and stick” configurations, sustainable ice batteries that flatten power demand while saving energy, smart autonomous civic infrastructure that makes schools and cities safer and smarter.  Download Brochure >

  • Thanks to your project, we won the BOMA award again. Oh yeah, our lighting and HVAC bills have gone way down too. Well done!

    Jan Church SHM Partners / Property Manager
  • People think that solar is too expensive or intermittent.  3fficient’s FreeCharge is something people connect with in a unique way.  They learn first hand that solar energy can be very reliable and should really be the primary fuel of choice for all our power needs.

    Arts Council
  • 3fficient, and their innovative partners, have developed brilliant urban furniture that is completely self-powered and changing how we look at and interact with urban infrastructure.

  • The public should be able to exercise and enjoy the outdoors day or night.  But providing lighting in parks, trails and transit stops is too expensive.  3fficient’s FreeCharge products provides lighting and many public safety services to any urban or remote locations where the sun might shine.

    Parks & Rec Director
  • We were fighting an uphill battle against rising utility costs and low cost foreign competitors. Your analysis of our operations and the solutions to lower our water usage by 95% will make a huge difference to our competitiveness.

    Stephen Travis Oregon Cherry Growers / Executive Vice President
  • Getting power to tight urban locations or remote locations is expensive and a big hassle.  3fficient’s FreeCharge products eliminate the high costs and hassles of bringing and maintaining power to new or remote locations.

    Parks and Trails Director
  • Wow.  These solutions are game changers.

    University President
  • In addition to the energy and maintenance savings, comfort (and productivity) of our employees has been greatly improved. Thanks for fixing our buildings and helping us keep our operating costs down. Great job team!

    Bill Lawrence VidFilm / Controller
  • This project saved us more than we expected. Thanks for the hard work and keeping the subcontractors on time. Tenant comfort and reliability has improved. That makes my job more enjoyable.

    Brad Heath CBRE / Property Manager, 101 N Brand, Glendale
  • We were really pleased how 3fficient educated us about energy efficiency, explored many options, came up with great "out of the box" solutions, and then walked us through the whole process.

    Larry Watt City of Encinitas / Director of Public Works
  • This was a marquis project, not just for Port Hueneme, but for the entire US Navy. While the energy savings are substantial, even greater value will be realized through the replication and adoption of your innovative "net zero energy" building retrofit by other public and private sector organizations. Your engineering is certainly industry leading. Thanks for the leadership and service.

    Chris Karandang US Navy / Port Hueneme (Home of the Sea Bees)
  • As a global manufacturer of building materials, we spend several hundred million a year on energy. So the slightest fluctuation wreaks havoc on our budgeting and materials prices. We are thankful for your help on our global energy management team and development of our enterprise-wide, real-time energy management program.

    Gary Groner Johns Manville / Global Energy Manager
  • As a Sustainability Advisor to schools and businesses, I am pleased to recommend your charging stations. The students and faculty at St. John's Prep School were really excited about the charging stations. Students and faculty were fascinated with the technology and that they could charge their devices using solar power and batteries. What a great education forum.

    Lisa Lillelund Saint John's Prep School
  • Your team has really helped us shave a bundle off our renovation plans, not to mention lowering future energy costs and improving tenant comfort.

    All the Doctors at Physicians Group Glendale Medical Office / All the Doctors
  • The way 3fficient has aggregated so much into their FreeCharge devices really saves us a lot of money while increasing safety and customer engagement.  This is a whole new paradigm.

    Transit Agency / CTO
  • Your management of the Load Curtailment (Demand Response) Program achieved phenomenal results and was a tremendous help to avoid blackouts for thousands of customers in our area (and the state). Above all, you treated our customers like gold working seamlessly as part of our team.

    Don Pappe Pasadena Water & Power / Director
  • This project went real well, our building looks better and it saved us a lot of money.

    Spence Wilson Transwestern Voit / Property Manager, 330 North Brand
  • This project has not only made our buildings more comfortable, the learning experience has improved dramatically and allows us to illustrate renewable energy, energy efficiency and energy management first hand.

    Dr. Jean Lecuyer Glendale Community College / Director of Science Education Center
  • We have used your solar lockers for a few events that we have been sponsors of now and each time they have proven to be amazing! The last event was a 4 day music festival, where we used two of the charging stations. The charging lockers were completely full after 12 minutes and remained full for the entirety of the festival! Your charging stations are a must for all of our activation areas!

    Samantha Kohn Alex & Ani / Event Marketing Manager
  • Well done folks! Thank You for the great audits and direction for our capital improvements.

    James Butcher CBRE / General Manager (801 N. Brand, Glendale)
