For many organizations, sustainability is a core priority, shaping how buildings are designed, operated, and maintained. Whether you’re overseeing a commercial office, an educational facility, or an industrial plant, pursuing LEED (Leadership in Energy and Environmental Design) certification is one way to put those values into action.
What often gets overlooked? Mechanical systems play a huge role in making LEED goals achievable. HVAC, energy monitoring, and building controls are central to performance, comfort, and long-term efficiency.
At Tessiers, we’ve spent decades helping facilities align their mechanical systems with sustainability goals, including LEED-certified projects across the Midwest. Here’s how it all comes together.
What LEED Certification Really Means
LEED is a globally recognized framework developed by the U.S. Green Building Council (USGBC). It evaluates buildings across multiple categories, including:
- Energy & Atmosphere
- Indoor Environmental Quality
- Water Efficiency
- Innovation in Design
Projects earn points in each category, which determine whether a building achieves Certified, Silver, Gold, or Platinum status.
LEED is about reducing environmental impact while creating healthier, more efficient spaces for the people who use them, through design, construction, and ongoing operation.
Where Mechanical Systems Make the Biggest Impact
Energy-Efficient HVAC Design
HVAC systems are typically the largest energy consumers in a building, which is why Energy & Atmosphere carries so much weight in LEED scoring. High-efficiency equipment, variable-speed drives, smart zoning, and optimized controls can dramatically reduce energy use.
During the design phase, energy modeling helps predict system performance and fine-tune decisions before installation begins. Done right, efficient HVAC design earns LEED points and lowers operating costs year after year.
Indoor Environmental Quality (IEQ)
Comfort and health go hand in hand. Mechanical systems directly influence indoor environmental quality by:
- Maintaining stable temperature and humidity
- Providing consistent fresh air ventilation
- Filtering airborne contaminants
In workplaces, schools, and healthcare settings, strong IEQ supports productivity, reduces absenteeism, and improves overall well-being, while also meeting LEED requirements. Read more about Improving Indoor Air Quality in Schools in our recent blog post.
Energy Monitoring and Building Analytics
LEED doesn’t stop once construction ends. Ongoing performance matters.
Energy monitoring and analytics systems allow facility teams to track usage, spot inefficiencies, and make informed adjustments. LEED may also award points for commissioning and ongoing commissioning, ensuring mechanical systems continue performing as designed, not just on day one, but years down the road.
Why the Design-Build Approach Matters
LEED success starts early. Tessiers’ design-build approach allows mechanical systems to be aligned with sustainability goals from the very beginning.
By handling design, fabrication, installation, and long-term service under one roof, we can:
- Reduce material waste through smarter fabrication
- Improve installation efficiency
- Ensure systems perform as intended, not just on paper
It’s a practical, collaborative way to turn sustainability goals into real-world results.
A Real-World Example: Cherapa Place
So what does this look like in practice? Cherapa Place in Sioux Falls is a prime example. As the first LEED Gold–certified project in South Dakota, it set a new standard for sustainable development in the region.
Tessiers joined the project early, during budgeting and system concept development, to evaluate HVAC options that balanced performance, efficiency, and cost for this 141,944-square-foot, six-story office and commercial building.
The final system included:
- A high-efficiency air-cooled water chiller
- Central station air handling units on alternating floors
- An underfloor air distribution system for enhanced comfort and air quality
- Direct digital temperature control and building automation for smart operation
Over 18 months, the focus stayed the same: create a space that supports both occupant comfort and environmental responsibility. That balance is the Tessiers standard.
Let’s Build What’s Next
As sustainability becomes more important to clients, employees, and communities, the buildings organizations choose to invest in, and occupy are sending a clear message.
If LEED certification is part of your next project, new construction, retrofit, or capital improvement, mechanical systems will be key to your success. With expertise in HVAC, fabrication, building controls, and energy management, Tessiers helps turn sustainability goals into high-performing, reliable systems that stand the test of time.
Let’s build smarter. Let’s build efficiently. Let’s build for the future.
