We put the gears in motion, and make sure they work.

A building is only as good as the sum of its parts. We approach buildings from a holistic perspective, ensuring all parts are working in concert to best meet and serve the needs of owners, operators, and occupants. From mechanical systems hidden from view to public spaces used everyday, we leave no stone unturned when tackling a project.

Our knowledge, expertise, and level of care allow us to operate in high gear. The multidisciplinary learnings and experiences within our core competencies of commissioning and efficiency work together and drive us to continuously improve and evolve our services.

What we do

Cx Associates is in the business of decreasing building energy use as a way to combat climate change through all of our service areas. We focus on innovation and best practices to deliver results that make a difference in individual buildings, or across efficiency programs.

Cx Associates’ independent design review resulted in both cost savings and more green alternatives for our expansion project. We were able to save$40,000 off the initial construction bids and meet project objectives including ongoing annual savings and a quiet energy conscious building.

Jeffrey P. Carlson
Sr. Project Manager at Engelberth Construction Inc.
I appreciate Cx Associates’ ability to provide us with that extra set of eyes during the design review process. Cx Associates’ ability to dedicate their time and expertise is like an insurance policy for us. It gives me the confidence to know our design engineers have done an adequate job and that they haven’t missed anything. Investing ahead of time eliminates problems and additional costs during the project.

Design Phase Services

Waiting until your project is in construction to think about energy efficiency and commissioning services is a missed opportunity to address issues before they're built. We can help by saving you on first costs, and potentially avoid serious code violations and costly repairs down the road. We offer design reviews that have proven to save building owners energy, time, and money.
