What looks like a simple equipment decision can quietly reshape your entire building. Indoor vs. rooftop systems isn’t just preference it’s budget, aesthetics, code, and constructibility all colliding in one choice.

At a glance, rooftop units feel like the easy answer to free up interior space and keep systems out of sight. However, that decision can introduce structural upgrades, screening challenges, and long-term maintenance constraints.

On the flip side, indoor mechanical rooms offer protection and accessibility but they come at the cost of valuable square footage and early coordination pressure. The key isn’t which option is “better” it’s understanding the ripple effects before design development locks you in.

MEP Design Insights | Why Submittal Coordination Breaks Down

Submittals aren’t failing because people don’t care. They’re failing because teams aren’t aligned.

In many projects, submittals are reviewed in isolation:
• Mechanical submits equipment
• Electrical isn’t verifying power requirements
• Structural isn’t confirming weights
• Architects aren’t seeing the downstream impact

Everyone assumes someone else checked it. That’s where risk lives.

A single missed detail like incorrect voltage or equipment size can trigger:
• Electrical redesigns
• Larger equipment rooms
• Ceiling conflicts
• Delays and added costs

Not because the design was wrong but because the coordination wasn’t there.

The most successful projects shift one mindset:
Submittals are not approvals. They are coordination tools.

When trades review together not separately projects move faster, stay on budget, and protect the design.

At the end of the day, strong coordination isn’t extra effort. It’s what prevents problems from showing up later.

MEP Design Insights | The Hidden Risk in Shop Drawings

Most project issues don’t start in design, they start in submittals.

Shop drawings are meant to confirm that what’s being installed matches the engineer’s intent.

But when incorrect information slips through like the wrong voltage or mismatched equipment it doesn’t just create a small issue it creates ripple effects across the entire project.

Here’s where things go wrong:
• Equipment is purchased before full cross-trade review
• Electrical requirements don’t match actual loads
• Mechanical equipment exceeds allocated space
• Submittals are reviewed in silos not as a coordinated system

Then the question comes up: Who is responsible?

Engineers review for general conformance not to redesign contractor selections. Contractors are responsible for what they purchase and install. But when coordination breaks down, the impact often lands on the architect.

Late changes. Redesigns. Compromised layouts.

The projects that avoid this treat submittals as a coordination checkpoint not a paperwork step.

Early alignment protects design intent.

MEP Design Insights | HVAC – Are Heated Floors Necessary?

Heated floors sound like a luxury upgrade in building design. But in many commercial projects, they’re not always the right HVAC solution.

Radiant floor systems circulate warm water through tubing embedded in the floor slab, heating a space from the ground up. When used in the right environment, they can create extremely comfortable spaces with even heat distribution.

But they also come with design considerations that architects should think about early in the project.

Here are a few things radiant floors can impact:
• Floor assembly thickness to accommodate the tubing
• Mechanical equipment like boilers, pumps, and manifolds
• Slower temperature response compared to forced-air systems
• Performance changes depending on flooring materials
• The continued need for separate systems to provide cooling and ventilation

Radiant heating often works best in spaces where comfort matters and occupancy is consistent—like lobbies, healthcare environments, schools, or certain residential-style buildings.

The key takeaway: heated floors can be a great solution, but they’re not automatically necessary. Like many HVAC decisions, the best answer depends on the building, how it will be used, and early coordination between architects and MEP engineers.

Everyone loves the idea of finding a pot of gold but successful building design rarely happens by luck.
One of the most common challenges architects encounter in commercial projects is discovering late in the design process that mechanical, electrical, and plumbing systems require more space than anticipated. When MEP systems are introduced too late, the results can include redesigns, reduced ceiling heights, larger mechanical rooms, or rooftop equipment that conflicts with the architectural vision.
Modern buildings place increasing demands on infrastructure. Energy codes require more efficient HVAC systems, electrification is expanding electrical service capacity, and ventilation requirements are growing. These changes often lead to larger equipment, additional electrical rooms, and more complex system coordination.
When these realities are identified late in design, they can impact budget, schedule, and aesthetics.
The most successful projects avoid these surprises through early coordination between architects and MEP engineers. By aligning infrastructure needs with architectural design from the beginning, teams can protect the design intent while ensuring systems meet performance and code requirements.
At Neville Engineering Services, we believe the real “pot of gold” in building design isn’t luck, it’s coordination.

MEP Design Insights | The Real Impact of the 2024 Energy Code
Energy codes are no longer just a compliance step they are shaping building design.

The 2024 Energy Code is influencing HVAC system selection, electrical infrastructure, building envelopes, and even roof space. When these requirements are discovered late in design, projects often face redesigns, added costs, or architectural compromises.

Common impacts architects encounter include:
• Larger or more complex HVAC systems
• Energy recovery and ventilation requirements
• Increased rooftop mechanical space
• Envelope and glazing performance limits
• Electrification and heat pump infrastructure

Early coordination between architects and MEP engineers helps avoid costly surprises and protects the design vision.

MEP Design Insights | Mechanical Rooms Always Grow
Mechanical rooms almost always end up larger than originally planned. Not because engineers want the space but because modern HVAC systems require it.

As projects move from schematic design into detailed engineering, real equipment sizes, ductwork, piping, and code-required service clearances quickly reveal the true space needed. Add stricter energy codes, higher ventilation standards, electrification, and smarter building controls, and mechanical systems become significantly more complex.

Common surprises include:
• Required service clearances
• Maintenance access zones
• Duct and piping distribution space
• Future system capacity
• Equipment replacement pathways

Early coordination between architects and MEP engineers helps protect the building layout and avoid costly redesigns later in construction.

MEP Design Insights | Electrical rooms are quietly getting bigger in commercial buildings.

Not because engineers want more space but because modern buildings demand far more power. When electrical infrastructure grows, it directly impacts building design.

Ten or fifteen years ago, electrical rooms were relatively compact. Today, they’re expanding in many projects due to several converging trends across the industry.

First, buildings are using more electricity than ever before. Technology loads have increased dramatically. Offices, healthcare facilities, retail environments, and even multifamily developments now support far more equipment, devices, and connectivity than they once did.

Second, the industry is seeing a strong shift toward electrification. Systems that were historically powered by natural gas are increasingly moving toward electric solutions. This change increases the demand placed on electrical service capacity.

Third, new infrastructure requirements are becoming common design considerations, including:
• Electric vehicle charging stations
• Larger HVAC equipment loads
• Expanded technology infrastructure
• Increased redundancy and future capacity planning

All of these factors require larger switchgear, additional distribution panels, more conduit pathways, and greater clearance space. The result is that electrical rooms often need significantly more square footage than architects initially anticipate.

The challenge is timing.

When electrical space requirements are identified late in the design process, it can force difficult adjustments to floor plans, circulation areas, or tenant space. Planning for electrical infrastructure early can prevent those surprises.

At Neville Engineering Services, we work with architects early in the design phase to anticipate these infrastructure needs so buildings can support both current requirements and future growth.
