  • Reviving Aging Infrastructure Through Retrofits

    Reviving Aging Infrastructure Through Retrofits

    When overseeing vast portfolios of aging infrastructure, a critical challenge looms: the degradation of asset value driven by deteriorating Indoor Air Quality (IAQ) and unsustainable energy costs. While the initial impulse may be to prioritize costly, full-system replacements, the smart, sustainable solution lies in strategic retrofitting, specifically targeting the core failure point: your HVAC system.

    The reality is that legacy buildings must compete with modern, high-performance facilities. When tenants and occupants prioritize health and efficiency, an aging asset with compromised air quality and skyrocketing utility bills quickly becomes a liability. This is particularly true in the post-pandemic era, where IAQ has become a non-negotiable metric of building quality and resilience.

    The Dual Threat for Aging Infrastructure: Corrosion and Contamination

    According to Buildings magazine, older infrastructure presents significant IAQ challenges stemming from its foundational systems. The most critical issue lies within the HVAC coils and internal components. Over time, these systems face a dual threat:

    1. Corrosion and Efficiency Loss: In environments with high humidity or industrial pollutants, evaporator and condenser coils are prone to corrosion and fouling. This degradation weakens the critical bond between the fins and the copper tubing, severely impeding heat transfer. An inefficient coil forces the HVAC system to run longer and harder, wasting energy and accelerating equipment wear.
    2. Microbial Contamination: Damp, aged coil surfaces become ideal breeding grounds for mold, mildew, and bacteria. When the HVAC system is the source of contamination, poor IAQ becomes unavoidable, as it circulates particulate matter and potentially harmful biological agents throughout the occupied space. This directly impacts occupant health and productivity, diminishing the asset’s value.

    For an asset owner, replacing an entire HVAC system is often prohibitively expensive and disruptive. The alternative targeted, high-performance retrofit strategy is essential for achieving modern performance metrics without the massive capital outlay.

    The High-ROI Retrofit: A Solution-Focused Approach for Aging Infrastructure

    Coat Zone’s advanced coatings are engineered to transform existing HVAC units into high-performance, long-life assets. This makes them the cornerstone of an intelligent retrofit strategy for aging infrastructure. Our solutions offer a proven path to simultaneously recover efficiency and dramatically improve IAQ.

    1. IAQ and Efficiency Recovery with CoilSafe Plus®

    To address the internal threats to efficiency and health, we recommend CoilSafe Plus®. This proprietary, ultra-thin, inorganic coating is applied directly to the coils. It then wicks deep into the structure to restore the critical heat transfer bond.

    • Efficiency: By restoring heat transfer, CoilSafe Plus® can help bring systems closer to their original factory efficiency. This often results in measurable reductions in kilowatt-hour usage and lower operating costs—the goal of any successful retrofit.
    • IAQ and Corrosion Defense: As an antimicrobial solution, CoilSafe Plus® creates a glass-like barrier that resists the adhesion of mold, mildew, bacteria, dirt, and debris. This permanent defense fights coil fouling and preserves optimal airflow. It also directly addresses the primary source of biological contaminants within the HVAC system, thereby improving IAQ for aging infrastructure.

    2. Asset Preservation with ThermalBlock™

    For units exposed to the elements, our ThermalBlock™ coating provides the external defense necessary to complete the retrofit. Applied to exterior cabinets and ductwork, this thermal radiant barrier blocks up to 93% of solar heat. By reducing the thermal load on the unit’s exterior, ThermalBlock™ reduces HVAC run-time, significantly extending the unit’s useful life and lowering energy consumption, especially during peak demand periods.

    The combination of internal protection (CoilSafe Plus®) and external thermal defense (ThermalBlock™) delivers an integrated, lasting retrofit solution that costs a fraction of unit replacement while providing a rapid, measurable ROI.

  • IAQ is Dead, Long Live IEQ

    IAQ is Dead, Long Live IEQ

    Why the Industry’s Focus Has Shifted from Air to the Total Environment

    For years, the HVAC and building management industries have rallied around the critical importance of Indoor Air Quality (IAQ). And rightly so. The quality of the air we breathe has a profound impact on health and productivity. However, as we move into a new era of building design centered on human well-being, the conversation has expanded. Today, the focus is squarely on Indoor Environmental Quality (IEQ), and leading industry bodies are making this comprehensive approach a priority.

    As a valued partner in optimizing building performance, Coat Zone understands that simply improving the air is no longer enough. Here is why IEQ represents the future of healthy, high-performing buildings and how our specialized solutions can help you meet this evolving standard.

    IEQ vs. IAQ: Understanding the Crucial Difference

    While often used interchangeably, IAQ and IEQ are fundamentally distinct. Think of IAQ as a critical subset of the larger, all-encompassing concept of IEQ.

    MetricFocusKey Components
    Indoor Air Quality (IAQ)The air we breathe.Pollutants (VOCs, particulates, carbon dioxide), pathogens (mold, bacteria), ventilation, and humidity.
    Indoor Environmental Quality (IEQ)The total experience inside a building.IAQ, Thermal Comfort (temperature, humidity), Lighting (daylight, glare), and Acoustics (noise control).

    IAQ specifically addresses the air’s health and comfort. It is about reducing concentrations of contaminants and ensuring adequate fresh air exchange.

    IEQ, on the other hand, is a holistic measure of the overall conditions inside a building that affect occupant health, comfort, and productivity [1, 2, 3]. It encompasses all the factors that impact human well-being. An environment with excellent air quality but poor lighting or uncomfortable temperature is still considered to have poor IEQ [4].

    The New Industry Mandate: ASHRAE’s Focus on IEQ

    This shift from a singular focus on air to a holistic view of the environment is being championed at the highest levels of the industry. The current ASHRAE President, Bill McQuade, has made IEQ the central theme of their 2025-2026 term under the initiative “Healthy Buildings: Designing for Life.” [5]

    ASHRAE’s focus stresses that the industry must move beyond simply reducing energy consumption. While decades of work have successfully improved energy efficiency, these measures have sometimes had the unintended consequence of negatively impacting the indoor climate. This new mandate calls on professionals to champion solutions that successfully balance energy efficiency with excellent IEQ. By integrating principles that address thermal comfort, lighting, acoustics, and air quality simultaneously, we ensure that buildings are not only environmentally sustainable but also conducive to the health and productivity of the people inside them [5].

    Coat Zone Solutions for Comprehensive IAQ and IEQ

    At Coat Zone, our specialized products are engineered to provide direct, measurable contributions across multiple IEQ pillars. This ensures your HVAC systems are optimized not just for energy, but for life.

    1. CoilSafe and CoilSafe Plus: Optimizing IAQ and Thermal Comfort

    HVAC cooling coils are ground zero for two of the biggest threats to IEQ: biological growth and inefficient temperature control.

    • Direct IAQ Contribution: CoilSafe and CoilSafe Plus are designed to prevent the proliferation of mold, mildew, and bacteria that thrive on wet coil surfaces. By eliminating these microbial contaminants at their source, we drastically reduce the concentration of airborne pathogens and odors circulated throughout the building, ensuring cleaner air for occupants.
    • Thermal Comfort IEQ Contribution: A coil free of biofilm is an efficient coil. By maintaining optimal heat transfer performance, CoilSafe and CoilSafe Plus enable your HVAC system to meet precise cooling and dehumidification setpoints without strain. This translates directly to enhanced thermal comfort, reducing the risk of stuffy, humid, or improperly cooled spaces, which are key components of IEQ.

    2. ThermalBlock: Enhancing Thermal Comfort, IAQ, and Acoustics

    Our specialized thermal barrier coating, ThermalBlock, impacts the built environment on multiple fronts.

    • Thermal Comfort IEQ Contribution: Applied to air handling unit casings, plenums, or ductwork, ThermalBlock provides a superior thermal barrier. This minimizes surface temperature fluctuations and prevents undesirable heat transfer, making it easier for the system to maintain stable zone temperatures and eliminate cold spots or drafts that cause occupant dissatisfaction.
    • IAQ Contribution (Condensation Control): By reflecting solar radiation before it can increase surface temperatures, ThermalBlock effectively eliminates condensation caused by cold air meeting hot metal. Condensation is the prerequisite for mold growth, meaning ThermalBlock is a proactive measure against moisture intrusion and mold proliferation, safeguarding IAQ.

    The Path Forward

    The future of high-performance buildings is focused on the whole human experience. Embracing IEQ is not just about meeting a standard; it’s about investing in the productivity, health, and peace of mind of every occupant. By leveraging comprehensive solutions like CoilSafe, CoilSafe Plus, and ThermalBlock, you ensure your HVAC systems are powerful contributors to the holistic health model that ASHRAE is now advocating for. Don’t settle for merely acceptable IAQ; strive for exceptional IEQ.
