If you manage a facility, you know the challenges all too well—aging equipment, rising operational costs, and the constant need for improvements. But with so many competing priorities, how do you determine where to invest, what upgrades will deliver the most value, and how to fund them efficiently?

At TEN, we specialize in energy-based performance contracting, guiding facility managers through a structured process to identify, design, and implement cost-effective solutions. Our goal? To help you reduce costs, improve efficiency, and build a more resilient facility while maximizing your return on investment.

Step 1: Preliminary Assessment–Laying the Foundation

Every facility has unique needs, so our process begins with a preliminary assessment to gather key data. We analyze:

• Energy consumption and utility rate details
• Existing equipment conditions and performance
• Potential opportunities for efficiency improvements

Our team conducts an onsite visit, meeting with operations and maintenance staff to understand daily challenges and site-specific constraints. Next, we develop a comprehensive list of energy conservation measures (ECMs)—ranging from lighting and HVAC upgrades to building automation systems and advanced energy-saving technologies.

Step 2: Investment Grade Audit–Turning Insights Into Action

Once we've identified potential improvements, we take a deep dive into the financial and technical feasibility of each ECM through a detailed energy audit called an Investment Grade Audit (IGA). During this phase, we:

• Conduct multiple site visits and install monitoring devices, as needed
• Analyze equipment lifecycle, system configuration, and operational strategies
• Assess cost-effectiveness and potential energy savings
• Make sure all proposed upgrades are viable, efficient, and aligned with your goals

Our construction team is actively involved in this stage to confirm that recommended improvements can be built safely, effectively, and within your required timeline.

Step 3: The Financial Breakdown – Making Data-Driven Decisions

This is where the rubber meets the road—at the conclusion of the IGA, we provide detailed, contract-ready financials for each scope item, including:

• Firm fixed costs: Transparent pricing for all recommended upgrades
• Guaranteed savings amounts: Clearly defined energy and cost savings projections
• Custom project selection tool: A unique resource that allows you to evaluate different ECM combinations and their net impact

With this information in hand, you can make a well-informed decision about which upgrades to pursue. Our performance contract ensures that your investment is protected with clear savings guarantees and a firm fixed price.

Beyond the First Project – Building a Long-Term Partnership

Many of our clients start with one project and continue working with TEN to implement additional phases. Since we’re already familiar with your facility and operational needs, we can seamlessly identify and execute new upgrade opportunities eliminating the hassle of starting a new procurement process every time.

As part of TEN’s employee interview series, Chris Van Horn, CEM, Director, Federal Programs, shares his thoughts on the energy industry, renewable technologies, and a new outlook on life.

Chris, what aspect of energy efficiency are you most enthusiastic about?

I am primarily interested in reducing the impact of climate change and conserving natural resources (fossil fuels). My goal is to conserve resources and incorporate renewable energy conservation measures (ECMs) into each TEN project that I work on.

Which renewable ECMs do you find to be most effective?

Solar photovoltaic (PV) and geothermal heating and cooling have become standard renewable technologies in many federal projects. I’m mostly interested in what future technologies will be introduced in the market. For example, there are interesting utility-scale power technologies that can become available soon including deep well geothermal energy to power steam turbines. This entails using fracking drills to reach hot layers of the Earth’s crust, tapping into a virtually unlimited heat source. Another interesting technology is nuclear microreactors, which will soon start testing. I can envision microreactors being used to power military installations and customers with large campuses.

How long have you been in the ESCO industry?

I’ve worked in the building energy-efficiency market since 2005 and have been developing federal energy savings performance contracts since 2012. I have been with TEN for almost four years.

What makes TEN special?

The small business feel: everyone from the top down is willing to roll up their sleeves and help in any way. Senior management is always accessible and there is no feeling of corporate bureaucracy. Because of our entrepreneurial mindset, TEN is open to and able to quickly adapt to the market. For example, recent improvements to investment tax credits (ITCs), which are valued at nearly 40 percent of project costs, make solar PV more financially viable. In less than a year, TEN pivoted and started to develop solar projects and financing solutions to take advantage of the ITCs on behalf of our customers. We are also expanding our Energy as a Service solution with recent project wins.

On a personal note, I know that you had a medical emergency last year. How has this experience changed you?

Going through an unexpected medical emergency gives me a new appreciation for what is important in life. I am so grateful for the support and encouragement I received from my co-workers, manager, and senior leadership. Many companies say their employees are the most important part of the business, but TEN leadership demonstrates this through their actions. The support that my family and I received during my recovery was exceptional.

What is the most exciting part of your job at TEN?

I really enjoy meeting with customers at the onset of a project and learning about their energy goals and pain points. I like the process of brainstorming and conceptualizing ECMs in collaboration with our customers and building the financial model as part of the solution.

Tackling aggressive or new ESG goals? It may be time to reconsider the old way of doing things. Projects are serving multiple purposes, and the marketplace has changed to prioritize flexibility and customization ahead of the more traditional evaluation measures.

Have you considered an Energy Services Company (ESCO) Energy partner? New and nimble ESCOs are helping tackle ESG goals in a different way. The new generation of ESCOs are offering more contract and financial structures than ever before, and helping customers use their energy projects to do more.

Each Project is Customized to Your Needs

Every energy project is unique. Different projects are designed to accomplish different goals, address different needs based on different priorities, and reflect different circumstances, environments, and infrastructure challenges. Customers who report the best experiences point to the fact that their projects were customized to meet their specific needs and financial conditions.

It’s important to select an ESCO partner that recognizes, solicits, and listens to the perspectives of all stakeholders impacted by the project, and an ESCO that is flexible and agile enough to pivot. The project should reflect the stakeholder’s input, and the customer’s voice needs to be equal in priority to a proven process and approach.

Vendor Neutral Equipment Selection

Equipment selection is always an important factor in the project’s long-term success. It is important to understand the difference a pure-play ESCO brings to a project. Some ESCOs that operate as a business unit within a larger technology or non-energy services organization make internally influenced selection decisions. Pure-play ESCOs are completely neutral and poised to select equipment, vendors, engineers, etc., based on value to the project stakeholders – without influence other than customer choice!

In addition, vendor and equipment neutrality lends itself to a competitive selection of equipment and vendors based on best value that reflects cost, availability, quality, maintenance, etc. Pure-play ESCOs can have the best experience collaborating with customer preferred vendors because their business model includes relationships with the marketplace.

Energy Performance Contracting Methodology

Guaranteed energy savings performance (GESA) contracts can be an effective contracting methodology that results in proven energy performance and measurable financial results. Many customers prefer the performance contracting design-build methodology over traditional design-bid-build. This moves much of the coordination and project budget risk away from the customer to the ESCO partner. Some ESCOs provide firm-fixed prices under a performance contract. In these cases, it is important to select a partner that has a record of delivering the contracted scope of work without change orders.

The landscape of ESCOs has changed significantly in recent years. Larger ESCOs that relied on stability as their value proposition are now competing with boutique ESCOs that deliver more value with lower cost-basis and less corporate bureaucracy. Many customers favor ESCOs that can deliver more scope for the same financial investment over others that have a higher cost of doing business.

Energy performance-based contracting models can include many contractual structures and many financing structures. Most customers look for an ESCO that has the stability to offer Power Purchase Agreements (PPAs), Energy Services Agreements (ESAs), and Efficiency-Energy-Infrastructure-as-a-Service Agreements (aaS) based on their unique and customizable financial goals.

Market Reputation

Procuring a long-term energy partner can feel daunting. At the end of the day, customers need a partner that makes it easy for them to get work done today and into the future. Performance contracts include a period of performance during which additional work can be completed without running another procurement; it is the easy button!

Look for an ESCO that can point directly to experience delivering multiple phases of work to customers and with high customer satisfaction scores. The Efficiency Network (TEN) was created 13 years ago to deliver the best value customer-centric energy and sustainability solutions. If you do not know who we are, visit us at www.TENsaves.com.

As part of Women’s History Month, Alison Shea, CEM, Senior Vice President, Business Development, shares her thoughts on women’s achievements in the field of mechanical engineering and her experience at TEN.

March is designated as Women’s History Month by presidential proclamation. The month is set aside to honor women’s contributions in American History. Women’s History Month is a time to recognize and celebrate the social, economic, cultural, and political achievements of women worldwide.

Alison, what has been your greatest achievement?

As it relates to “women’s history,” it’s twofold. I studied mechanical engineering at a time when there were very few females in this field. I completed my undergraduate degree at Virginia Tech, when there were only two women in the construction/HVAC program. I am very proud of the progress women have made since then. Women bring a different prospective to projects in our industry than men; one is not better than the other, they are just different.

Because I work in a non-gender traditional field, my kids have grown up without bias. My choices set the course for them to think outside the box regarding their interests and career choices. They did not see limitations. Plus, they brag about having a “super boss mom”…. Who wouldn’t love that!

Women’s History Month is a call to action to accelerate gender equality. As a business leader at TEN, how do you see equality evolving?

I see gender equality absolutely evolving. The challenge though continues; it has moved away from bias and towards availability. Women are still a minority in the STEM field. In my experience, people are no longer opposed to hiring women, the problem has changed to availability of women in our field. We still have a long way to go to reinforce STEM as a career opportunity for women.

What woman has been influential in your life?

Ruth Bader Ginsburg

You have achieved so much success in business as a leader. What qualities do you think make a great leader?

Transparency, communication, leading by example, knowing your “stuff”, passion for your job, and humility.

What advise do you have for other women who aspire to leadership positions?

Be your own voice, advocate for yourself, and surround yourself with people you respect that you view as a mentor or sponsor.

What is your favorite part of working at TEN?

The culture, it’s fun! People are open to each other, engaged, and have a shared vision for the future of the company. Most of all, there are no silos, which is very rare in business.

Every energy project is unique. Different projects are designed to accomplish different goals, address different needs based on different priorities, and reflect different circumstances, environments, and infrastructure challenges.

We look forward to working with Pittsburgh Public Schools, Wilkinsburg School District, and TEN to achieve healthy, sustainable learning and teaching environments for students, faculty, and administrators.”

Successful completion of Phase I will unlock an additional $1 million in funding for Phase II, which involves conducting energy audits and developing a strategic implementation plan. Phase III, an award of $14 million, will be allocated for renovations, upgrades, and construction costs. To progress through Phases II and III, Pittsburgh Public Schools must cover a proposed cost share of $4.7 million (Phase II: $52,632 and Phase III: $4,666,667).

As part of its submission, Pittsburgh Public Schools acknowledged the potential impact of recommendations pending as part of its facility utilization plan process. The list of schools noted below as part of the District’s submission may change over the course of phased funding due to changes to the District’s portfolio of schools.

Allegheny 6-8, Grandview K-5, Milliones 6-12, Weil K-5, Beechwood K-5, King K-8, Morrow K-8, Westinghouse 6-12, Brashear High School, Langley K-8, Roosevelt K-5, Woolslair K-5, Classical 6-8, Mifflin K-8, Schiller 6-8, Kelly Primary, Faison K-5, Miller K-5, Spring Hill K-5, Turner Intermediate

The City of Pittsburgh is set to transform its cityscape and enhance the quality of life for residents thanks to our LED Streetlight Modernization Project. The Department of Mobility and Infrastructure (DOMI), in partnership with The Efficiency Network, Inc. (TEN) will evaluate the existing inventory of approximately 39,000 streetlights and replace outdated high-pressure sodium (HPS) fixtures with LED fixtures, bringing modernity and energy efficiency to Pittsburgh’s streets.

The City will also conduct a study that identifies where additional streetlights and poles are needed to ensure a standard of safety, security, and quality of life in all Pittsburgh neighborhoods.

Our commitment to sustainability and equity during design of this new lighting infrastructure will reduce energy consumption and improve service reliability through reduced outages. This eco-friendly transition aligns with Pittsburgh's green initiatives and helps in reducing the City's carbon footprint.

The website, https://www.pghled.org/  has been created to help City of Pittsburgh residents learn more about this project. The Progress Tracker keeps outlines the construction team’s installation overall progress as well as installation by neighborhood. It’s as easy as plugging in a zip code!

Dark Sky Lighting Ordinance

Pittsburgh is joining the ranks of 52 other U.S. cities committed to providing residents with a safer, lighter, cleaner future. Though Pittsburgh is the first city in Pennsylvania to embark on this modern, eco-friendly path, our efforts are supported by over 25 states and 300 countries worldwide.

In 2021, the City of Pittsburgh’s Division of Sustainability and Resilience announced a new “Dark Sky Lighting” ordinance for all city parks, facilities, and streetlights. Dark Sky Lighting refers to the use of technology placing light only where needed for comfort and safety, lower color temperature providing a warmer glow of light, and having the correct amount of light output and better uniformity. Under this ordinance, the LED Modernization Project will adhere to Dark Sky principles for its newly installed streetlights.

Joe Richards • 07.25.24

As part of TEN’s employee interview series, Joe Richards, director, business operations, shares his thoughts on working in the energy industry.

Joe Richards was recently promoted from principal project manager to director, business operations for The Efficiency Network (TEN) . TEN’s purpose is to help customers modernize their buildings and save money in the process. In his new role, Joe oversees multiple energy efficiency projects and project managers throughout the project lifecycle. Joe has been with TEN for eight years.

Joe’s approach is to connect with customers on a personal level, establish common ground to build a relationship with each customer, and treat internal and external customers respectfully. Admittedly, Joe says developing long-lasting relationships takes a lot of time and patience, and this is what sets TEN apart from our competition. We take the time to establish personal customer relationships, gaining customer trust that we have their best interests in mind when we design, engineer, and construct energy efficiency projects. Once trust is established, customers typically return to TEN for repeat work.

Joe takes the same level of customer service and extends it to internal customers. He is excited about the potential in his new role to lead TEN’s business operations as a resource and a partner to other TEN departments. His goal is to help ensure that the TEN team is working towards the same goals without losing focus on our external customers.

The best part of Joe’s job is “the variety of work daily. I work with new and different types of customers in varying industries, and I find it very rewarding to learn about their businesses. Getting to know customers on a personal level is my goal.” Joe feels that we need to constantly challenge each other to be better and TEN leadership provides a flexible and professional atmosphere where this can happen.
