Who We Are.

Located in the Greater Minneapolis/St. Paul area (MN), Efficiency Commissioning LLC specializes in building commissioning, recommissioning, retro-commissioning, and ongoing commissioning with a focus on energy efficiency and sustainability. 

What Makes Us Different...

With an entrepreneurship spirit, enthusiasm, and the desire to inspire trust, Javier and Elizabeth opened Efficiency Commissioning LLC. We are an engineering firm that focuses primarily on building commissioning. We love making buildings work and helping them maintain optimum performance levels.
​
We understand the needs of the building Owner. We are not going to stay in an office, writing reports – we will be in your building, talking to your people, and getting to the root of your problems. Efficiency Commissioning LLC is a hands-on commissioning company.
​
We have seen the difference this hands-on approach achieves – the companies that stay out of the construction site will take longer to get the job done, require more revisions, and ultimately cost you more money. By going into the construction site, we can quickly assess and investigate problems as they come up and more accurately diagnose those problems. It expedites the commissioning process and, in the end, saves you money.

We are also interested in creating long-term relationships with you so we can provide continuous service to keep your buildings running smoothly. Working with you, we come up with an ongoing commissioning schedule which means that when problems come up, we will be there to help.

Why We Do It?...

Today, companies face a difficult challenge – balancing the desire to focus on green energy and the realization of their bottom-line and return on investment. That is where Efficiency Commissioning LLC comes in. We work hard to keep your operating costs low while spending more time in your buildings. Our mission is to help your facilities be more efficient while keeping more money in your pocket.

From past work experience we have witnessed that with the proper skill set and preparation, building commissioning can make a building function as intended, often optimizing the system to an even higher standard. The commissioning efforts have a high return on investment, which you could see within the first year. Whether it is commissioning a new building, recommissioning/retro-commissioning an existing building, or opting for ongoing commissioning, the savings earned will more than pay for the commissioning costs.
​
Ultimately, we want to help a company’s bottom line while also lessening their carbon footprint. Even the smallest adjustment can make a huge difference in energy bills. Let us help you to make your buildings as efficient as possible – it is what we do, and we are good at it.
