New Public Electric Vehicle Fast-Charging Station Completed in Chatham

Chatham, MA – Rivermoor Energy and Weston & Sampson, in partnership with Eversource and the Town of Chatham, announces the completion of the first fully publicly accessible electric vehicle (EV) combined fast charging plus conventional charging station project in Chatham, at the Eldredge Public Parking Lot on 365 Main Street.

Located on the historic Eldredge Garage site, the new EV charging station fully opened for charging on March 25. The state-of-the-art, public access facility includes eight new EV chargers provided by FLO – four Level 3 DC fast chargers and four Level 2 chargers – for 30-minute to multi-hour charging for local community members, Main Street business owners, employees, and visitors.

“The activation of EV charging stations at the Eldredge Garage Visitor Center is a significant step forward in our efforts to reduce our carbon footprint,” said Jill Goldsmith, town manager, Chatham. “By making it easier for everyone to own and operate EVs, we can help to reduce the number of traditional gasoline-powered vehicles on our roads, which will result in cleaner air and a healthier environment for all of us. I would like to thank all our partners who have helped make this project a reality.”

“The development of new charging

stations at the Eldredge Garage site and across Massachusetts is pivotal to increasing EV adoption,” said John H. Tourtelotte, founder and managing director of Rivermoor Energy. “With the redevelopment of this local landmark, the Town of Chatham is building on its rich history, transforming a classic American auto service station and advancing it into an era of electrified transportation, innovation, and environmental stewardship. We’re building critical infrastructure for EV drivers who are enjoying Chatham’s natural resources and supporting its local businesses.”

Johanna D. Hall, CEM, senior team leader at Weston & Sampson, said, “Transportation accounts for the largest portion of total greenhouse gas emissions in Massachusetts, 38% of the Commonwealth’s total, but by increasing access to crucial and scarce public EV fast charging and conventional charging, we are breaking down barriers to entry for electric drivers and encouraging new customers to park, charge, and explore Chatham’s wonderful Main Street by foot. This will reduce air pollution and vehicle congestion and increase revenue for local businesses and restaurants. It’s a win-win for the environment and local small businesses.”

“Our expansion into Chatham is part of FLO’s ongoing commitment to building a comprehensive, reliable charging network that supports sustainable transportation across the region,” said Thomas Koetje, territory sales director at FLO. “Through our collaboration with Rivermoor Energy, Weston & Sampson, and the Town of Chatham, we’re ensuring Cape Cod has a robust, easy-to-use EV charging network to meet growing demand.”

“Eversource is proud to support the Town of Chatham in creating an example of access to clean transportation for other communities, on Cape Cod and across the Commonwealth, to follow,” said Tilak Subrahmanian, vice president of energy efficiency and electric mobility, Eversource. “Through close collaboration with our industry partners and local stakeholders, Eversource has helped bring this groundbreaking project to life,

providing critical infrastructure through our Make Ready program to accelerate EV adoption for Chatham residents and visitors that supports their commitment to sustainable energy.”

HP Interviews Jeff Camuso of Charles D. Sheehy, Inc.

High-Profile’s Anastasia Barnes recently caught up with Jeff Camuso, president of Charles D. Sheehy, Inc. (CDS), a supplier of pipe, valves, fittings and mechanical equipment serving the mechanical contracting industry of New England.

Anastasia Barnes: Charles D. Sheehy has been in business for over 70 years. What do you believe has been the key to the company’s longevity and continued success?

Jeff Camuso: Charles D. Sheehy consistently works in concert with our clients and strives to help make their processes more efficient. We always want to be a silent, efficient partner to the top MEP contractors, never a competitor. Those of us who are fortunate to be part of this company are simply stewards for a legacy that started in 1951 by my greatgrandfather and grandfather. If an action can challenge our mission, or threaten our customers, we don’t do it.

“We don’t want to be everything to everybody, nor can we be. We always try to operate as an extension of our clients. We want our actions, and in this case, our branding to more closely assimilate to theirs.” – Jeff Camuso

AB: Your company recently underwent a rebranding initiative. What inspired this transformation, and how does it reflect the future direction of CDS?

JC: Being founded in 1951, there is an inherent importance to making any type of change to our identity, and we take that responsibility serious. It was determined that it was a good time to streamline our branding and nomenclature to resemble who we are in 2025: a strong, laser-focused independent firm. We don’t want to be everything to everybody, nor can we be. We always try to operate as an extension of our clients. We want our actions, and in this case, our branding to more closely assimilate to theirs.

AB: Technology and e-commerce are reshaping many industries, including distribution. How is CDS leveraging digital tools to stay ahead in a competitive market?

JC: Similar to how we choose which products to go to market with, we needed to be mindful about how we entered the e-comm space. Our site and interface needed to appeal not to homeowners and designers as many of our competitors’ do, but to MEP coordinators, designers, and estimators. Additionally, we are investing in artificial and ambient intelligence and tech that we think will help our clients plan and schedule product releases. There has been a growing disconnect between project genesis/coordination and actual on-site installation. We as distributors haven’t done enough to close that loop. That is a priority for us now.

AB: The “Sheehy Standards” play a big role in your company culture. Can you share how these principles shape your team’s approach to business and customer relationships?

JC: We tried to identify some of the great

lessons and tenets we have learned from those who came before us and shaped this firm, and package them into weekly themes. We ended up with 35 principles that influence our decision-making and shape our philosophies. You can find our weekly features standard at standard.cdsi.com and on the wall of my office. Each Monday, a member of our leadership team pushes out a company-wide communication giving their perspective on that week’s Sheehy Standard and how we can best exemplify it.

AB: Looking ahead, what are your biggest priorities and goals for Charles D. Sheehy, Inc. in the next five and 10 years?

JC: Consolidation and M&A activity has changed what a good distribution partner

looks like, but it really shouldn’t. We are here to serve our clients and help them be profitable. We’ll continue to grow our product portfolio to include solutions that compliment what we already do and offer service that help the contractor. It remains so important to embrace our independence and I feel that we are better positioned to grow with our partners than many others due to that independence. Since 2017, we have had success growing into the plumbing space thanks to our partnership with some great manufacturer and contractor partners. We look forward to continued growth in that area. Additionally, we have had some recent gains in the traditional heating, cooling, and process pipe space.

Achieving Speed to Market for Hyperscale Data Centers

For hyperscale data center developers, the race is on: Scale faster, lower costs, and meet ambitious sustainability targets, all while navigating the inherent challenges of a slow and resource-intensive building process. But what if the rules of the game could be rewritten?

At Salas O’Brien, we’ve done just that. By merging our deep expertise in data centers, power generation, advanced manufacturing processes, and construction, we’ve redefined how hyperscale facilities are designed and delivered. The result? Achieving in 12 months what once took 24.

The key is to think differently. Rather than treating these facilities as static structures, we approach them as complex machines engineered for performance, precision, and speed. This shift in mindset isn’t just about breaking tradition; it’s about setting a new standard for speed to market while achieving quality and longterm operational excellence.

The Challenges Holding Hyperscale Development Back

Traditional workflows for these complex buildings often create a disconnect between design and implementation, leading to inefficiencies, rework, and delays. Misaligned handoffs between design teams, engineers, and contractors slow progress and leave little room for innovation or agility. Meanwhile, global supply chain disruptions have made sourcing critical materials increasingly unpredictable, further compounding project delays and adding unforeseen costs.

Labor shortages are another pressing issue; the demand for skilled workers in construction far exceeds supply. Without experienced crews, timelines elongate, and quality risks increase. At the same time, inefficiencies in traditional processes result in change orders that drive up budgets, leaving developers with difficult trade-offs between cost, speed, and quality.

Perhaps the most pressing challenge, however, is the urgent need for faster delivery. With skyrocketing demand for digital infrastructure, the conventional approach to building data centers simply can’t keep pace with the industry’s growth trajectory.

To stay competitive, hyperscale cloud companies, AI providers, and data center developers need solutions that bridge

the gaps between design and execution, simplify supply chain complexity, and reduce reliance on scarce resources.

What if a Data Center were Designed and Built like a Complex Machine rather than a Building?

For centuries, construction has relied on sequential processes. While digital tools have brought improvements, the fundamental approach to taking a building from design through construction hasn’t evolved much since the creation of the Colosseum.

But there are other possible delivery models for these complex facilities. Consider that complex machines are engineered as integrated systems; every component is optimized for efficiency, precision, and performance. The manufacturing process is modular, streamlined, and scalable.

Salas O’Brien has applied these same principles to hyperscale data centers, introducing industrialized processes, modular construction, and systemlevel integration. The results speak for themselves: faster timelines, reduced complexity, and high-quality facilities that deliver the precision of a finely tuned machine.

Breaking Down the Process: A Smarter Path to Hyperscale Delivery

The foundation of Salas O’Brien’s accelerated approach lies in rethinking every stage of the data center lifecycle: design, fabrication, and construction. Here’s how we make it happen:

• Integrated design and delivery teams. With architects, engineers, and construction experts collaborating from

the start, we eliminate silos and deliver seamless coordination. This allows for real-time problem-solving, compresses design timelines, and mitigates risks, protecting clients from costly gaps between design and implementation.

• Advanced building information modeling (BIM) for speed and precision. We leverage BIM as more than just a design tool – it’s the backbone of our manufacturing-inspired approach. By creating highly detailed, dynamic models that integrate every system and component into a digital twin, we can streamline coordination, predict construction timelines with precision, and resolve potential clashes before they happen. This process accelerates delivery and minimizes delays.

• Integrated power and water solutions. Hyperscale data centers require massive energy capacity and cooling infrastructure, often in regions with strained utilities or limited resources.

At Salas O’Brien, power generation plants and waste water recycling plants are designed as core components of the facility rather than add-ons. This integrated approach ensures efficient, scalable, and sustainable power and water solutions, enabling faster implementation and long-term operational resilience.

• Modular construction and prefabrication. A modular approach allows for parallel construction processes, addressing labor shortages and supply chain challenges. Mechanical skids, electrical systems, and structural modules are prefabricated

off-site to exacting standards. These components arrive ready for rapid assembly, significantly reducing onsite construction time and risks.

• End-to-end project oversight. From supply chain management to onsite commissioning, our holistic approach ensures every element of the project aligns with the client’s goals for speed, sustainability, and cost control. This approach creates exponential efficiency, helping hyperscale data centers achieve speed to market while maintaining quality and performance.

How Salas O’Brien can help Data Centers Achieve Speed to Market

As a leader in this sector, Salas O’Brien is redefining what’s possible for hyperscale data centers by delivering facilities more quickly and with greater precision and sustainability. Our team’s expertise in engineering, advanced manufacturing processes, and construction ensures that your data center not only comes online sooner but also exceeds expectations for performance and reliability.

From day one, we work as an integrated partner, identifying risks, solving challenges, and leveraging the latest tools and methods to accelerate every phase of a project. Whether it’s through modular construction, advanced BIM techniques, or seamlessly integrated power and cooling solutions, our approach is designed to meet the demands of today’s hyperscale developers.

IBEW Local 103, NECA Greater Boston Celebrate CEPAP Graduates

Boston – The International Brotherhood of Electrical Workers (IBEW) Local 103 and the National Electrical Contractors Association (NECA) Greater Boston celebrated the first graduating class of the Clean Energy Pre-Apprentice Program (CEPAP), designed to prepare young adults (ages 18-24) for careers in the state’s clean energy industry. The program was funded through a grant from the Commonwealth of Massachusetts Department of Apprentice Standards.

The 10-week, tuition-free program introduces participants to the union electrical industry with a focus on electric vehicle charging stations, battery storage, solar power, and wind power. This program is part of a statewide effort to engage a younger, more diverse workforce and connect them to family-sustaining careers.

The 10-week, tuition-free program introduces participants to the union electrical industry with a focus on electric vehicle charging stations, battery storage, solar power, and wind power. This program is part of a statewide effort to engage a younger, more diverse workforce and connect them to familysustaining careers.

“As the Healey-Driscoll Administration works towards achieving its climate goals and growing clean energy jobs for Massachusetts, we value partnerships like with IBEW and NECA to prepare our future workforce and upskill our existing workers,” said Labor and Workforce Development Secretary Lauren Jones. “Thanks to the collaboration with IBEW Local 103 and NECA, we are delivering the state’s first pre-apprenticeship program for clean energy electricians and expanding access and opportunity for a diverse talent pool of workers to pursue meaningful careers in this industry right here in Massachusetts.”

The Greater Boston Joint Apprentice Training Center (JATC) spearheaded the program, preparing participants for entry into the IBEW 103 apprenticeship

program. The program’s participants receive hands-on training in EV charging, solar, wind, and other renewable energy fields at JATC’s facility in Dorchester.

“This program is aimed at addressing the demand for clean energy solutions and the skilled workforce needed to install, maintain, and upgrade clean energy systems well into the future,” said Lou Antonellis, business manager/financial secretary with IBEW Local 103. “No one else trains apprentices as Local 103 IBEW does — no one has a $10 million annual training budget, three full-time administrators, 13 full-time teachers, 25 part-time teachers, and trains apprentices on the job for over 10,000 hours while providing 6000 electricians with annual licensing updates.”

“It’s critical that we provide tomorrow’s workers with skills training needed to

meet the evolving demands facing the state and in our local communities,” said Chris Sherlock, training director, JATC of Greater Boston.

“Collaboration with local, state, and federal partners has been critical in

Understanding TEDI and Its Role in Building Energy Codes

What is Thermal Energy Demand Intensity (TEDI)?

TEDI refers to the total amount of thermal energy a building requires for space heating, expressed on a per-unit-area basis (typically in kBtu/ft2/yr or kWh/m2/yr). It reflects the amount of energy output from all heating systems in the building that are used to maintain comfortable indoor temperatures.

The primary factors that affect TEDI are building design and massing, envelope assembly performance (including thermal bridging effects), ventilation, energy recovery, internal loads, and local climate. It should be noted that cooling demand can also be used to define an alternate TEDI metric to evaluate space cooling performance of the building.

The lower the TEDI, the less energy is needed to heat the building – signaling better performance. By focusing on TEDI, design teams can look to optimize passive solutions such as envelope performance, mitigating thermal bridging, improving air tightness, and optimizing ventilation systems.

The Role of TEDI in Building Energy Codes

TEDI has recently become an important metric in building energy codes due to its focus on improving the thermal performance of buildings. Local building energy codes around the world are beginning to require project teams to meet specific TEDI thresholds for new construction or major renovations.

In these codes, TEDI is often integrated as a part of a whole-building energy performance approach in combination with other metrics such as energy use intensity (EUI) and carbon emission reduction (greenhouse gas intensity, GHGI). By incorporating TEDI, building codes aim to ensure that buildings are designed to use as little energy as possible for heating purposes, contributing to broader goals of energy conservation and climate change mitigation.

Some notable examples of building codes that incorporate TEDI include:

• Massachusetts Building Code, Stretch Energy Code (USA): Implemented in 2023 in more than 85% of all municipalities in the state, the Stretch Code includes a pathway to compliance that requires meeting a heating TEDI and cooling TEDI threshold.

• Toronto Green Standard (TGS) (Canada): In development since 2010

and currently in its fourth version, TGS includes mandatory TEDI, EUI, and GHGI thresholds for new private and city-owned developments over 4 stories in the city of Toronto.

• British Columbia’s (BC) Step Code (Canada): This code came into effect in stages starting in 2017, with different steps representing progressively higher levels of energy efficiency and TEDI thresholds. It became mandatory for new buildings in most regions of BC starting in 2022, with further tightening of energy requirements expected in the following years.

• The Passivhaus Standard (International): Although not an energy code, this voluntary building standard has gained traction worldwide. It mandates a maximum TEDI of 15 kWh/m²/yr, promoting the concept of buildings that require minimal space heating.

Five Key Considerations When Using TEDI

When implementing TEDI as a metric within building energy codes, there are several critical factors that need to be considered to ensure it serves as an effective tool for improving energy performance.

All of the factors below affect how TEDI thresholds are developed and determined by municipalities, government organizations, and other authorities having jurisdiction. Specific and detailed energy modeling guidelines that are tailored to modeling for TEDI threshold compliance are critical to ensure consistent results across all energy modeling, allowing for a fair comparison between building performance and design.

For example, the development of the TEDI thresholds for the Toronto Green Standard and Massachusetts Stretch Code was undoubtedly different and therefore resulted in different energy modeling guidance for each code. Knowing this,

and the variation in climate between Toronto and Massachusetts, we see the following variation in TEDI thresholds for each energy code:

1. Climate and Location

The thermal energy demand of a building is highly dependent on the climate in which it is located. Buildings in colder climates will naturally have higher thermal energy demands than those in warmer regions. Therefore, TEDI thresholds may vary depending on location, with energy codes often adjusting the target values based on local climate conditions.

To provide consistency when evaluating TEDI, energy modeling guidelines typically provide weather files to use in energy modeling based on the location of the project.

2. Building Envelope Performance and Air Tightness

The building’s envelope – the walls, roof, floors, windows, and doors – plays a significant role in determining its thermal demand. A well-insulated building with thermal bridge mitigation, high-performance windows, and airtight construction will generally have a lower TEDI compared to a building with a poorperforming envelope.

As such, TEDI-based energy codes can drive the adoption of advanced insulation materials, better window technology, thermal bridging mitigation products and solutions, and more airtight construction practices.

3. Ventilation System Control and Energy Recovery

The amount of outdoor air delivered to a building and the manner in which it is delivered has a significant impact on TEDI. The presence and effectiveness of heat recovery ventilation (HRV) or energy recovery ventilation (ERV) will affect how hard the rest of the building’s heating systems have to work in order to

maintain comfortable indoor conditions. Optimized control of ventilation systems, including delivery based on demand or occupancy (demandcontrolled ventilation, DVC) and supply air temperature setpoint control, will also impact TEDI.

4.

Internal Gains and Occupancy Patterns

Thermal energy demand is also influenced by internal heat gains and their operating schedules, such as those from appliances, lighting, and occupants. Buildings that contain a large amount of equipment, are heavily used, or have a high density of people will have lower space heating needs than buildings that are sparsely occupied and have low internal heat gains.

Properly accounting for internal gains in the TEDI calculation is essential for achieving accurate assessments of a building’s energy demand. To provide consistency and avoid project teams utilizing high internal gains to drive TEDI down, energy modeling guidelines typically prescribe values to use for internal gains as well as operating schedules to use in energy models.

5. Building Size and Design

Larger buildings or those with complex designs may present challenges when optimizing TEDI. However, advancements in building modeling and simulation tools allow architects and engineers to design for low TEDI even in larger or more intricate buildings.

The layout, geometry, and orientation of a building, as well as how it is divided into spaces (e.g., open plan vs. compartmentalized), will all influence its thermal demand. In general, as exterior envelope area (normalized by floor area; this is called the “form factor”) increases, so does TEDI.
