When we formed e2s in 2003, we wanted to help building owners access a greater level of expertise and value in their pursuit of energy efficiency in sustainable, high performing building infrastructure and operations.

So we hand-picked a group of outstanding project developers, engineers and field technicians and empowered them by giving them each a voice to streamline process and create unique solutions. By investing in education and professional skills for continuous improvement, e2s is known to deliver best in class, high integrity energy efficiency advice and services.

The result is a unified and technically expert in-house team that works seamlessly together in all engagements, creating confidence in our clients across the United States.

Our Mission

  • Support clients as superb trusted technical advisors through our talent, experience, and ethical actions.
  • Creating sustainable total lifecycle building solutions, with a focus on value, integrity and our clients.
  • Conduct all business with external and internal clients with integrity and respect.

Our team has over 400 years’ experience in the built environment, with deep knowledge in MEP/R/BMS systems. We operate on every project as if it was our own, supporting clients as extensions of their in-house team.

Core Competencies

Our programs encompass lifecycle consulting design, commissioning & balancing, acquisition and pre-lease due diligence, advice on the integration of sustainable technologies, green building, and net zero energy strategies, with peer review of M&E, plumbing, refrigeration and energy management systems.

Our implementation services include turn-key energy upgrades, capital planning and execution of equipment upgrades and end of life renewals.

Communicating what we see and learn during these projects creates a continuous improvement path for clients that informs engineering, operations, and facilities maintenance while generating sustained savings.

We’re passionate about what we do, and our services are designed to provide the support and confidence to enable clients and their partners to achieve excellence in their work.
