The Science of Healthy Buildings

Healthy buildings are buildings that prioritize the quality of indoor environments. They bring together data science, machine learning, and best-in-class technology to facilitate connectivity and visibility. These buildings address key criteria, such as air quality and ventilation, to optimize indoor shared spaces.

Did you know humans spend 90% of their lives indoors?

Indoor environments are humans’ natural habitats. We spend 90% of our life indoors,
breathing mostly indoor air up to 20,000 times a day. What are we doing to make our
natural habitats - indoor environments - healthier shared spaces?

There are invisible risks present in indoor environments

In order to protect indoor spaces from harmful microorganisms, it's critical to address all vectors of transmission: air, surfaces, and person-to-person contact. A key mitigation strategy is to implement the CDC's guidelines regarding layered strateagies and hierarchies of controls. A multi-layered approach to environmental safety ensures that indoor environments are safer for occupants and avoids dependence on human behavior alone. As a sustainable, effective disinfection solution, UV-C can play a key role in a layered strategy for achieving indoor environmental quality.

How UV-C works

Ultraviolet (UV) light is light with a wavelength between 10 and 400 nanometers (nm). This light is not visible to the human eye. UV light has three sub-types: UV-A, UV-B, and UV-C.

What is UV-C?
How is UV-C deadly to organisms?
What organisms can UV-C inactivate?

Of the three types of UV light, UV-C has the shortest wavelength (100 or 200 - 280 nm). Consequently, UV-C light cannot pass through Earth’s atmosphere. As a result, it is germicidal or deadly to organisms on Earth because they have not been naturally exposed to it.

UV-C light inactivates microorganisms by penetrating their cell walls and disrupting the replication of their genetic material. This disruption causes molecular lesions or dimers to form in their DNA. These dimers or lesions are covalent linkages between consecutive bases along a DNA strand rather than across a strand, and their presence prevents replication.

UV-C can inactivate harmful microorganisms such as bacteria, viruses, mold, and mildew.

UV-C as a general disinfection method is recommended by
the world’s leading health organizations
