Assessing the Role of GUV in Health, Indoor Air Quality, and Energy Efficiency.

Minneapolis, MN—Light Progress, a global innovator in UV-Cdisinfection technology, has completed a pioneering pilot installationat Cardigan Ridge, a Senior Living Community in Minneapolis, in partnership with Noble Electric, a premier electrical contractor specializing in top-notch electrical solutions energy efficiency andcutting-edge technology.
The project employs advanced Upper Room Germicidal UV (URGUV)systems, HVAC-integrated Germicidal UV (GUV) technology, and in-room air purification devices to evaluate the impact of UV-C technology on health outcomes, air quality, and energy efficiency inresidential care environments.

Innovative Technology meets practical Application
The pilot installation incorporates advanced UV-C devices certified for germicidal efficacy andsafety. The systems aim to achieve improved air changes per hour (ACH) while optimizing energyuse, demonstrating that high indoor air quality can be maintained without increased energy demands on HVAC systems.
Noble Electric executed the installation, leveraging certified expertise through the NALMCO GUV Certification program. This ensured compliance with industry standards and enhanced theimplementation's reliability.

High-Precision Monitoring and Data Collection
A core component of this initiative is the use of Network Thermostat thermostats equipped with real-time CO2 monitoring and data-logging sensors. These state-of-the-art systems continuouslytrack CO2 levels as a marker of indoor air quality and ventilation efficiency, ensuring precise, high-quality tracking throughout the facility. This data provides critical insights into how UV-C technology enhances air changes per hour (ACH) without increasing energy consumption in HVAC systems.

Advanced Modeling and Simulation of UV-C Technology

The project, in collaboration with the Lyles School of Civil and Construction Engineering at Purdue University, will involve a comprehensive analysis of the role of GUV technology in maintaining air quality.
Renowned researchers from Purdue will lead efforts to conduct detailed modeling and simulations of the UV-C systems. Utilizing advanced tools, they will map UV-C intensity and distribution to ensure compliance with safety standards while optimizing germicidal efficacy. They will also design and simulate strategies aligned with the ASHRAE 241 standard, quantifying the effects of UV-C technology on air changes per hour (ACH).
This work aims to provide actionable insights and validate the practical benefits of UV-C applications.

Comparative Health and Environmental Analysis
The project will compare health data from Cardigan Ridge with historical records and data from control facilities in the surrounding area. This approach will enable researchers to identify and quantify UV-C systems' specific benefits in enhancing residents' health outcomes.

F.A.Q.

Ultraviolette Strahlen sind elektromagnetische Wellen, die Teil des Lichts sind. Elektromagnetische Wellen werden in drei Hauptwellenlängenbereiche unterteilt, die in Nanometern (nm) angegeben werden: Ultraviolette Strahlen (UV) 100-400 nm Sichtbare Strahlen (Licht) 400-700 nm Infrarotstrahlen (IR) 700-800.000 nm UV-Strahlen werden wiederum in drei Banden unterteilt:

  • UV-A (315-400 nm) mit bräunenden Eigenschaften;
  • UV-B (280-315 nm) con proprietà terapeutiche e di sintesi della vitamina "D";
  • UV-C (100-280 nm) mit keimtötenden Eigenschaften.

UV-C (100-280 nm) hat eine starke keimtötende Wirkung und ist bei einer Wellenlänge von 265 nm am wirksamsten. Die keimtötende Wirkung der UV-C-Strahlung erstreckt sich auch auf Bakterien, Viren, Sporen, Pilze, Schimmelpilze und Milben; sie ist hauptsächlich auf die zerstörerische Wirkung der UV-C-Strahlung auf ihre DNA zurückzuführen; die UV-C-Strahlen schädigen nämlich ihren Fortpflanzungsapparat und verhindern ihre Vermehrung.

Bakterien, Viren, Sporen, Pilze, Schimmelpilze und Milben sind alle empfindlich gegenüber UV-C und können daher durch UV-C beseitigt werden. Mikroben können keine Resistenz gegen UV-C-Strahlung erwerben, wie es bei der Verwendung von chemischen Desinfektionsmitteln und Antibiotika der Fall ist. UV-Strahlung ist umweltfreundlich. Eine Umweltverschmutzung ist bei der Verwendung normaler Desinfektionsmittel unvermeidlich. Außerdem besteht die Gefahr, dass durch das direkte Einatmen der Dämpfe oder das Verschlucken von Lebensmitteln, die durch den Kontakt mit den chemischen Desinfektionsmitteln verunreinigt wurden, schwerwiegende Schäden entstehen können. In den Bereichen, in denen auf chemische Desinfektionsmittel nicht verzichtet werden kann (Lebensmittelindustrie, Pharmazeutik, Gesundheitswesen usw.), ermöglicht der Einsatz ultravioletter Strahlen bei der Desinfektion eine Verringerung der Desinfektionsmittelmenge mit erheblichen Kosteneinsparungen und größerer Rücksicht auf die Umwelt, wobei der Desinfektionsgrad beibehalten und fast immer verbessert wird. UV-C-Geräte können in Räumen und Maschinen installiert werden und so programmiert werden, dass sie Tag und Nacht den gleichen Desinfektionsgrad aufrechterhalten und somit ideale hygienische Bedingungen ohne Schwankungen gewährleisten. Im Gegensatz dazu entfalten chemische Desinfektionsmittel ihre volle Wirkung erst bei ihrer Anwendung. Bei der Verwendung von mit LIGHT PROGRESS ausgestatteten Geräten sind die Betriebskosten gering; man kann sagen, dass ein 'LIGHT PROGRESS' UV-C-System außer dem normalen Lampenwechsel keine Wartung erfordert. Das Preis-/Leistungs-Verhältnis ist hervorragend, die Geräte sind leistungsstark und haben eine lange Lebensdauer. Deshalb ist die Keimabtötung durch UV-C im Vergleich zu anderen Systemen (oder im Zusammenspiel mit diesen) kostengünstig und hochwirksam.

I raggi UV-C funzionano davvero, se applicati correttamente e con le dovute precauzioni. La differenza fra un progetto di qualità e una applicazione senza risultati è data dalla profonda conoscenza dell'argomento e dall'esperienza acquisita nel tempo. Dal 1987 Light Progress realizza progetti di successo in tutto il mondo e ha acquisito una clientela costituita da Società importanti in tutti i settori che necessitano di condizioni igieniche verificate per generare prodotti e servizi di qualità.
