Transforming a Mass Timber Office Vision into Mechanical Reality

Working alongside Aberthaw Construction Corp, the commercial team at Denommee Plumbing, HVAC & Electric (DPHE) successfully completed the core HVAC build-out of a 72,000 square foot office building in Newington, New Hampshire—a project that demanded precision, innovation, and exceptional craftsmanship.

Unlike conventional commercial construction, this project featured a mass timber structural system, a rapidly growing building method recognized for its sustainability and reduced environmental impact. Mass timber construction emits approximately 30% fewer carbon dioxide emissions than traditional steel or concrete—and when factoring in carbon sequestration, it can be considered carbon negative.

But with sustainability comes complexity.

Because the building design intentionally left mechanical systems fully exposed, there was no margin for error. Every duct run, every connection, and every fabrication had to meet not only performance standards—but also architectural expectations.

What Makes Mass Timber HVAC Projects Unique?

Mass timber buildings are fundamentally different from traditional commercial structures. For mechanical contractors, they introduce a unique set of challenges:

• Exposed systems require architectural-grade finishes

• Limited concealment options increase coordination demands

• Structural penetrations must be carefully planned

• Sustainability goals demand high-efficiency HVAC solutions

In this environment, HVAC systems are no longer hidden infrastructure—they become visible design elements.

That’s where Denommee’s expertise in commercial sheet metal fabrication and HVAC installation becomes a critical advantage.

Project Scope: High-Performance HVAC Installation

Denommee’s scope included the fabrication and installation of a complete commercial ducted HVAC system designed to integrate seamlessly with the building’s exposed architecture.

Key Scope Highlights:

• Installation of spiral sheet metal duct systems in:

  • Oval configurations

  • Round ductwork

  • Square duct sections

• Connection and coordination with 36 air handling units (AHUs)

• Precision fabrication to meet both mechanical performance and visual design standards

• Integration with broader mechanical systems, including VRF equipment totaling 90 tons of capacity (covered in additional project scope)

Precision Sheet Metal Fabrication: Where Craftsmanship Meets Performance

In a traditional building, minor imperfections in ductwork can often go unnoticed. In this project, every detail was visible.

Denommee’s team approached this challenge by elevating fabrication to a higher standard:

Off-Site Prototyping for Superior Results

To ensure consistency and quality, Denommee utilized off-site prototyping for key duct components. This approach allowed the team to:

• Refine fabrication techniques

• Ensure precise fitment before installation

• Reduce on-site rework

• Maintain schedule efficiency

Architectural-Grade Installation

Each duct run was installed with attention to:

• Alignment and symmetry

• Clean joint connections

• Consistent spacing and support

• Visual uniformity across exposed ceilings

The result is a system that performs efficiently while also contributing to the building’s modern aesthetic.

Why Exposed Ductwork Requires a Different Level of Expertise

Exposed HVAC systems are increasingly popular in modern commercial design—but they require a contractor capable of delivering both engineering precision and visual craftsmanship.

Denommee’s approach ensures:

• Clean, professional appearance suitable for office environments

• Proper airflow and system balancing

• Long-term durability and serviceability

For property owners and developers, this translates into a building that not only functions efficiently—but also enhances tenant experience and perceived value.

Efficiency, Coordination, and On-Time Delivery

Despite the complexity of the project, Denommee’s team delivered results that exceeded expectations in both quality and efficiency.

Key success factors included:

• Close coordination with Aberthaw Construction Corp

• Detailed planning and sequencing

• Skilled field crews with commercial HVAC expertise

• Strong project management oversight

This ensured the project was completed on time and under demanding conditions, without compromising workmanship.
