Green Building Consulting (LEED)

The most effective green projects are created when there is synergy between all members of the project team.

Efficiency Matters serves as the catalyst for this synergy. We augment a project team’s resources with our dedication, knowledge and experience of sustainable building design and construction.

Our passion for green building drives us to meet a project team’s needs through a holistic, integrated design process. While our direct client may be the owner, architect, contractor or facility manager, we invariably serve every team member to ensure the best possible results.

We are dedicated to the end result in each and every project. Our consultation focuses on strategies that produce the best life-cycle cost impact with improved environmental performance

What is LEED?


LEED evaluates environmental performance from a "whole building" perspective over a building's life cycle. The program has grown tremendously since then by proving itself a viable method of providing a third-party green building certification tool designed to ensure building owners and occupants that their building meets stringent standards of performance.

Together we can make your next project efficient, healthy, and environmentally friendly. The core green building fundamentals will be addressed:

  • Site selection
  • Water efficiency
  • Energy & Atmosphere
  • Materials & Resources
  • Indoor Environmental Quality

We can help you through all stages of your project to make sure the desired result is achieved!

Mike Rodriguez has more than 15 years’ experience in construction management and has spent the last 7 years specializing in green building. Mike began his “green” work at Energy Logic as an energy auditor and rater for new construction and existing homes. During his time with Energy Logic he saw a real need in the industry for a reliable and knowledgeable contractor to perform energy retrofits and green builds.

    Here are just a few examples of what our customers are saying.

    Jim and Karin Higgins of Fort Collins, CO
    In the fall Efficiency Matters did a major upgrade to the efficiency of our home. It turned out we had a home with many air leaks that were robbing us of needed heat in the winter and we were losing our cool in the summer. Efficiency Matters did a comprehensive analysis of the house and recommended several things that could be done to tighten the house and make our heating and cooling systems operate more efficiently. Recommendations were made considering the return on investment value. We have gone through a winter and half of a very hot summer and could not be more pleased. Our utility bills are roughly half what they used to be. Great job Efficiency Matters, I will recommend your services to anyone.

    Ryan and Katy Kirkpatrick of Wellington, CO
    "We would definitely recommend having an energy audit done by Efficiency Matters.
    Greg was knowledgeable, professional and honest. We really appreciated that he told us about many improvements that we could do ourselves (and exactly how to do them), in addition to completing two larger improvements for us. We found the price of these “retrofits” reasonable and workmanship excellent! As first-time homeowners, this was a great investment for us and we are very happy with the company we chose. Thanks Greg!"

    Gary Zook of Fort Collins, CO
    I would describe Greg as honest, thoughtful, conscientious, thorough, and hard working. I've worked with many contractors through the years and while most of them do a decent job, a few of them really impress with both their skills and attitude. Greg is one of the best and I would not hesitate to recommend him for improving the energy efficiency of your home.

    Scott Rogers of Windsor, CO
    Greg, I wanted to give you a follow-up on how things are working. Since yesterday was such a hot day we really got to see how things were working. I must say we are VERY HAPPY with the results. Amy said the house stayed very cool until after 7:00PM. Then the A/C came on for only a few minutes. We used the Whole House Fan around 9:00 PM and it cooled the upstairs 2 degrees (making the whole house the same temp). We slept very comfortably last night. This is exactly the results we were hoping for. Thank you so much!
