Building EnergetiCx is an independent commissioning firm working together as a team to bridge the gap between design, construction, and operation.

Studies show that we spend more than 90% of our lives inside buildings. The design, construction and operation of those buildings affect our lives in many significant ways. The built environment drives the demand for energy efficient and healthy buildings. As an owner advocate, Building EnergetiCx bridges the ever widening gap between design, construction, and operation by verifying that the building systems are installed and performing as expected reducing liability, ensuring thermal comfort, increasing occupant productivity, and ensuring adequate indoor environmental quality.

This is why the independent, third-party commissioning of building systems is essential. At the point of functional testing, tremendous investment in procurement and installation is typically well underway. With tight construction schedules and budgets on the line, stakes are high.

It is at this critical juncture when the expertise of Building EnergetiCx is especially important to the project team. Impartial and fully credentialed, Building EnergetiCx makes the start-up of the building systems for any building safe and smooth.

Commissioning with Confidence
Even with the very best design and construction documents, difficult technical issues can unexpectedly arise as commissioning gets underway. That’s when engaging Building EnergetiCx becomes a clear advantage to the project team.

Managing and mitigating risk is key to effective commissioning by keeping everyone on the same page for the duration of the project. Deeply versed in all aspects of building systems, Building EnergetiCx knows how commissioning can affect related priorities like benchmarking, future energy costs and the overall sustainability of any structure. The firm excels in executing a wide range of commissioning standards, offering extensive experience with such options as whole building commissioning, existing building commissioning, re-commissioning and continuous commissioning.

With Building EnergetiCx on the job, the project team can look forward to opening with the assurance that the building system will start up, stay up and perform as expected.


About Us

Headquartered in Charlotte, North Carolina, Building EnergetiCx is an independent commissioning firm that has successfully served on over 230 projects, regionally, nationally, and internationally. With repeat clients and referrals representing nearly 94 percent of the project roster, the firm has quickly established an exceptional track record of commissioning and related energy consulting work since its founding in 2011 by President Shane Nault.

To-date the firm has commissioned more than 18 million square feet of commercial, institutional or industrial space for facilities totaling more than $2 billion in value. More than 85 projects are LEED certified, with four (4) of those achieving the rigorous “platinum” rank – the highest possible for overall sustainability, as determined by the U.S. Green Building Council.

Because of the choice to engage with Building EnergetiCx, many clients earn recognition important to their business reputation. Building EnergetiCx, for example, was the commissioning agent on several projects named as finalists in 2014 and 2015 for the prestigious “North Carolina Sustainable Business Awards.” And, thanks to the strong leadership support by the Building EnergetiCx team, a client recently received the Talking Walls Award for Small Commercial buildings from the North Carolina Sustainable Business Awards.

​Shane Nault, PE, CEM, CCP, LEED​ ​ AP BD+C
Commissioning Provider| Energy Engineer

President Shane Nault is a leader in the commercial building sector, having twice been honored as a rising contributor to the industry. He is one of the select few named in two “Forty Under 40” tributes, first in 2013 by the Charlotte Business Journal and again in 2014 by Building Design and Construction Management Magazine. He has served on the board of the North Carolina Chapter of the U.S Green Building Council, Association of Energy Engineers Piedmont Chapter, and Southeast Chapter of the Building Commissioning Association.

Mr. Nault was principal-in-charge for a mid-sized mechanical engineering firm in Virginia before advancing as its director of project management. Realizing that there was a disconnect on how buildings were designed, installed and operated, Mr. Nault transitioned his career path towards commissioning. He now oversees all of the administrative, marketing and technical functions for Building EnergetiCx. With a keen eye for talent, Mr. Nault is responsible for resourcing the Building EnergetiCx teams organized for each project, maintaining an extensive network of trusted, highly-qualified partners to scale up services for clients when their needs exceed staff capacity.

Mr. Nault holds a bachelor’s of science in architectural engineering technology from Vermont Technical College and a master’s degree in engineering management from Old Dominion University. He is a licensed professional engineer in North Carolina, Virginia, Pennsylvania, and Georgia, a certified energy manager (CEM), and a certified commissioning professional (CCP). Mr. Nault is also a LEED accredited professional with a specialty in Building Design and Construction (LEED AP BD+C) as established by the U.S. Green Building Council.



The design, construction, and operation of buildings has become increasingly complex and demanding to meet an ever changing landscape. Whether it is a new or existing building, many architects are increasingly expanding their scope to include energy components in their designs. Building systems, including the enclosure, security, life safety, lighting, plumbing, heating and cooling systems are complex. On-site renewables and the advance of “intelligent” buildings (among many other emerging technologies) present fresh challenges. The future of energy code compliance, meanwhile, promises to add still more importance to commissioning. Building EnergetiCx is a valued and effective partner in guiding the project team through these challenges.

Through our commissioning process we ensure the building systems are functioning optimally and efficiently both at installation and throughout the life of the facility. This in turn provides comfortable and safe environments, maximizes operational efficiency, and ensures regulatory requirements are met.

The specialized focus on commissioning and energy consulting means that Building EnergetiCx can accept and serve effectively on assignments at any stage in the life of a building – design, construction or operation.


Commissioning- A Closer Look

As the third-party provider of commissioning services, Building EnergetiCx will, in most cases, contract directly with the building owner. It is this independent role that brings objective, pragmatic insight to the project team as it looks to commission building systems.

Understanding & Influencing Energy – The Consulting Role

Buildings consume 41% of the energy and 70% of the electricity in the United States. While important today, managing energy consumption for buildings will be of even greater importance for future generations. Building EnergetiCx works with building owners and project teams from the design phase to the final operation of the building to understand a building’s energy usage and operation.

Building EnergetiCx works with clients to influence and fine-tune building energy use. Our services include predictive analysis of a building’s energy through building energy simulations to optimize building performance for future buildings and evaluate the energy performance of existing buildings. For clients interested in validating their commitment to sustainable business practices through sustainable building rating systems, Building EnergetiCx will assist with credit development, proper filing and final certification.

Our full energy consulting portfolio includes:
  • Building Energy & Facility Assessment

  • Building Energy Simulation

  • Net Zero Energy Buildings Strategies
