When looking to build or renovate your home or office, looking at emerging trends can inspire a project with long-term utility and timeless style. Trends in the New Hampshire construction industry include efforts toward greener designs and increased energy efficiency, which keep the overall maintenance costs and energy use down. Our panel shares their insights into the specifics they are seeing in their work.

What are the emerging trends shaping the construction industry? How can businesses align their strategies with these developments for a competitive edge?
As with many industries, technology is pushing and shaping the construction industry from the design to the actual construction. Building Information Modelling (BIM) is becoming much more common and accepted in design and construction projects. With BIM, you can create a 3D computer model of the entire project including the parking areas, utility connections and building construction, which allows owners, engineers and contractors to visualize the final development and detect any conflicts before construction. To gain a competitive edge, businesses should always be looking at how technology is affecting their industry and should aim to be ahead of their competitors in adopting new technology.
Amid evolving environmental concerns, how are sustainability practices influencing construction projects, and what are the key considerations for businesses looking to adopt eco-conscious approaches?
Sustainability practices have long been a focus in civil engineering design and construction. In the early to mid-2000s, there was a big push for LEED Certification which was a way to demonstrate that a development went above and beyond the construction requirements for sustainability. Since the 2000s, municipal regulations and building codes have been revised to incorporate many of LEED Certification’s sustainability requirements, so it is now common practice in the construction industry to minimize environmental impacts and focus on sustainability.
In the context of urbanization and infrastructure growth, what role does innovative project management play in ensuring the successful execution of complex construction endeavors, and how can businesses excel in this area?
For urbanization and infrastructure growth, project management and future development planning are absolutely critical. My firm is involved in several large mixed-use developments that require substantial expansion of existing sewer, water, stormwater and electrical systems. When considering expansion of existing infrastructure, the existing systems’ total capacity and connection points need to be considered as well as what additional demands a new development will place on existing systems.
With a focus on safety and regulatory compliance, what steps should businesses take to mitigate risks and ensure the well-being of workers and stakeholders in construction projects?
Safety and regulatory compliance start with a company culture that prioritizes safety. My firm tells our field personnel that they can always say “no” to any task in the field if they have any safety concerns. Additionally, focusing on safety equipment is paramount in promoting a safe work environment. The cost of safety equipment and gear is negligible compared to the lost time and medical expenses of a workplace injury or safety incident.

As the construction industry looks ahead to new mechanical code changes, refrigerant requirements have become a hot topic of conversation. These regulations could significantly impact mechanical designs for future projects, and staying ahead of the curve is critical. Here’s a quick look at what’s driving these changes, why they matter, and how you can prepare.
Why are refrigerants being phased down?
The phasedown of hydrofluorocarbons (HFCs) under the 2020 AIM Act is the centerpiece of the U.S. Environmental Protection Agency’s (EPA) strategy to reduce greenhouse gas emissions. HFCs are commonly found in refrigerants like R-410A, and they have a high global warming potential. The goal is to reduce HFC usage by 85% by 2036, requiring a shift toward more sustainable refrigerant options such as A2L refrigerants.
How will the new regulations impact mechanical design?
This phasedown represents a significant shift in how mechanical systems are designed. While A2L refrigerants offer environmental benefits and improved efficiency, they also introduce unique challenges:
R-410A is being phased out. The current refrigerant standard for HVAC systems, R-410A, will be replaced by A2L refrigerants with lower HFC’s.
A2L refrigerants will be the new standard. These refrigerants have lower global warming potential, greater energy efficiency, making them a more sustainable choice. However, A2L is mildly flammable (Class 2), which requires updated safety measures.
New safety requirements for HVAC designs. Refrigerant lines that penetrate more than one floor or ceiling assembly will need ventilated shafts, either natural or mechanical. Exceptions may apply for smaller systems serving single units.
What are the new requirements?
A2L refrigerants will be the standard for new HVAC, refrigeration and heat pump systems.
Rated shafts will be required for refrigerant lines passing through multiple floors to address flammability concerns.
Existing systems using R-410A will be allowed to remain in use until January 1, 2026, but manufacturers are already phasing out the production of R-410A systems. Replacement parts and repair options for older systems will become increasingly scarce.
Why do these new changes matter?
Transitioning to A2L refrigerants will help the construction industry achieve environmental goals without compromising performance. However, the shift introduces complexities in design, safety and installation that developers, engineers and contractors must navigate. Additionally, some states have already implemented requirements for mechanical ventilation and emergency backup power for these rated shafts.
How is Maugel DeStefano Architects preparing?
As architects, we are committed to guiding our clients through this transition. Our approach includes:
Close collaboration with suppliers. We’re coordinating with vendors to ensure a smooth switch to A2L systems, establishing timelines and evaluating integration with existing designs.
Project-by-project assessments. Each project is analyzed to incorporate energy codes, compliance requirements, and HVAC system options for maximum efficiency and safety.
Client education. We’re keeping clients informed about these changes, advising on long-term costs and addressing compatibility issues between older and newer systems.
Our priority is to ensure that developers, contractors, engineers and policymakers understand how these new regulations will shape future projects. By proactively addressing these changes, we aim to deliver compliant, efficient and cost-effective designs while supporting environmental sustainability.
If you have questions about how these changes might affect your projects, please reach out to us. We’re here to help you navigate the evolving landscape of refrigerant requirements.
