IAQVEC 2026. An international conference focused on the future of indoor air quality, ventilation, and energy conservation in buildings.

Seeing our real-world hospital research accepted and presented at this level is incredibly meaningful for our team at Citra.

What makes this work different is that the conversation was never just about “installing UV.”

The focus was engineering measurable outcomes inside the AHU.

For Facilities Engineering professionals:
Cooling coil biofilm is not simply a maintenance issue.
It quietly impacts heat transfer, airflow stability, pressure drop, energy consumption, and long-term system performance.

For Sustainability and Energy leaders:
Some of the largest hidden decarbonization opportunities in buildings may already exist inside the HVAC systems operating 24/7 behind the walls.
Improving thermal performance inside the AHU can create measurable reductions in fan, pump, and chiller energy demand.

For Infection Prevention and Healthcare professionals:
Environmental control strategies should not stop at the occupied space alone.
HVAC systems play a critical role in the overall indoor environmental ecosystem of a facility.

What I appreciate most about this experience is seeing researchers, engineers, and healthcare professionals beginning to look at these systems together instead of separately.

That collaboration matters.

Because real building performance happens when infection prevention, facilities engineering, and sustainability objectives stop operating in silos.

Grateful to Dr. Deok-Oh Woo, Assistant Professor-PhD in Architecture, University of Maryland, the research partners, and everyone involved in validating years of real-world field work.

This recognition is a huge honor for Citra.

One thing I continue noticing in the energy and sustainability industry:

Organizations will spend significant money attending conferences focused on innovation, decarbonization, operational efficiency, and ESG strategy.

But when a real-world, peer-reviewed solution is presented that has already demonstrated measurable HVAC energy reduction inside operating facilities, the conversation often immediately becomes:

• “We require 3 bids”
• “Maybe next budget cycle.”
• “We’re just comparing lamp pricing.”

That response reveals a much larger issue in our industry.

Because engineered building performance is not a commodity purchase.

The real conversation should be:
• What measurable performance objective was the system designed around?
• Was the outcome validated?
• Was measurement & verification performed?
• Was long-term operational impact measured?

Too often, organizations publicly discuss innovation while internally evaluating advanced solutions through lowest-first-cost procurement logic.

And that mindset quietly keeps many buildings operating below their actual performance potential for years.

Sometimes the biggest sustainability opportunities are not outside the building.

They already exist inside the AHU.

Citra’s high-intensity UV-C systems work at the intersection of infection prevention and energy efficiency helping healthcare facilities reduce airborne pathogen risk while significantly lowering HVAC energy consumption.

Unlike traditional approaches, UV-C operates continuously inside the AHU, delivering:

✔ Real-time disinfection of moving airstreams
✔ Elimination of biofilm on cooling coils
✔ Measurable reductions in energy, maintenance,
and emissions

Validated in a peer-reviewed hospital field study, this is a solution designed for both clinical safety and decarbonization goals.

Lighting upgrades are often treated as simple fixture replacements but in reality, they impact operations, maintenance strategy, and long-term energy performance.

At, Citra, we don’t just swap out lights. We apply lighting design principles and the latest lighting technologies to improve safety, efficiency, and how spaces are actually used across any type of facility.

If you’re considering an upgrade or simply want to understand what’s possible call 866-577-7398.

When a 100+ year-old church needs lighting upgrades, there’s no room for error.

At Our Lady of the Scapular Parish, we delivered a solution that respected their space, timeline, and budget, while transforming the altar lighting beyond what they imagined.

We are honored to share that our paper, “High-Intensity UVC Irradiation of Air Handling Units for Enhanced Energy Efficiency Under Varying Biofouling Risks,” has been accepted for presentation and publication at IAQVEC 2026 in Los Angeles.

Our research focuses on real-world application of high-intensity UV-C inside operational AHUs, not lab simulations, but live healthcare environments with varying biofouling risks.

The findings demonstrated measurable thermal performance recovery (UA improvement up to 18.4%) while also addressing microbial risk within the air handling unit, connecting energy efficiency, sustainability, and infection prevention in a way that is often discussed separately but rarely studied together in the field.

Hospital-acquired infections are clinical events.

But they also have environmental contributors.

As healthcare systems navigate sustainability goals, deferred maintenance realities, and infection prevention priorities, upstream mechanical systems deserve more attention.

I welcome thoughtful dialogue with:

• Epidemiologists
• Infection Prevention & Control leaders
• IPC educators
• Facilities & engineering teams
• Sustainability officers
• Healthcare executives

If your organization is evaluating energy recovery strategies, HVAC hygiene, or environmental risk mitigation, I would value the opportunity to exchange insights and learn from your perspective.

Looking forward to engaging at IAQVEC 2026 and beyond.

Hospital-acquired infections are not only clinical events.

They are environmental events.

Air Handling Units (AHUs) can become microbial reservoirs.
Peer-reviewed research has shown biofilm accumulation on cooling coils can harbor organisms such as Aspergillus and other pathogens of concern. HVAC systems are not the sole contributor to infection risk, but they are an upstream mechanical component that is often underexamined in infection prevention strategy.

When biofilm develops on a coil, the consequences are twofold:

• Increased environmental pathogen burden
• Degraded thermal performance and rising energy demand
Yet alignment across healthcare teams remains a challenge.
Infection Prevention focuses on clinical transmission pathways.

Facilities focus on uptime and maintenance budgets.

Administrators evaluate capital through ROI frameworks.
Each group is operating correctly within its mandate.

But without integrated data, the full picture is missed.
When properly engineered, UV systems are not “add-ons.”

They are performance-driven mechanical interventions.

Science-based UV solutions can:

• Remove biofilm from cooling coils
• Reduce microbial reservoirs within AHUs
• Improve thermal conductance
• Lower HVAC energy consumption
• Automate coil hygiene
• Extend equipment life
• Contribute to reduced environmental infection risk
In real-world, peer-reviewed applications, energy savings alone have produced 2–3 year paybacks, often exceeding lamp maintenance costs many times over.

This isn’t about claiming HVAC is the sole source of infection.

It’s about recognizing that upstream environmental controls strengthen downstream infection prevention.

Healthcare invests heavily in PPE, surface disinfection, and isolation protocols.

Addressing mechanical reservoirs upstream strengthens the entire framework, while reducing operating costs.

Safer environments.

Lower energy consumption.

Longer equipment life.

The question isn’t whether UV works.

The question is whether it’s engineered to deliver measurable outcomes.

Lighting upgrades are often treated as simple fixture replacements.

In reality, they impact operations, maintenance strategy, and long-term energy performance.

In environments where air handling performance directly impacts energy, infection control, uptime, and decarbonization goals, the level of evidence behind a solution matters.

Case studies can show outcomes.
White papers can explain viewpoints.

Both have value.

But neither undergo independent academic scrutiny.

When decisions affect:

• Hospital-acquired infection risk
• Data center thermal stability
• Chiller plant energy consumption
• Scope 1 & 2 carbon reduction targets
• Capital planning and ROI justification

Validation standard becomes critical.

Peer-reviewed research follows defined scientific methodology.
It is conducted or led by academic researchers.
It is reviewed by independent experts before publication.
The experimental design, data analysis, and conclusions are evaluated for rigor.

Our recently published AHU UVC study went through this process prior to publication.

For healthcare systems managing infection risk and energy budgets…
For data centers where airflow stability and coil performance affect uptime…
For sustainability leaders tasked with measurable decarbonization…

Evidence-based engineering is not a marketing advantage.

It is a risk management strategy.

If you would like to review the published study or discuss how this applies to your AHUs, I’m happy to connect.
