Use Far-UVC to Being Safe Together

The issue of user health has always been a concern of designers and officials.
With the spread of COVID 19 and its spread, new principles in space design will be created.
Since the onset and spread of the disease, our team has made plans in this field to prevent the spread and elimination of the disease chain along with the activity and presence of users in urban areas and the use of urban facilities with the least risk.
The new arrangement of furniture, attention to social spacing, design of handles and openings, tips and innovations related to toilets, space and user disinfection systems, were among the items designed in the past.

We predict that with the outbreak of coronary heart disease and its spread, new principles in design and architecture will be created.
Sunlight, especially it's ultraviolet light, is known as one of the most effective disinfectants, which has been used by humans since the beginning.
Later, with the advancement of science artificially, ultraviolet lamps were used to disinfect spaces and objects.
And now, with further studies, advances in science, review of research and design samples, their upgrading and optimization, we have become acquainted with a specific wavelength of ultraviolet light that, in addition to its ability to kill viruses, is not harmful to humans and animals.
Items that were made available to the public, industrial designers, and architects through experiments and research of different groups and related science specialists for free. By studying and observing the presented designs, we were able to create a smart and responsive space, a safe space away from viruses. Design with the ability to expand the space.

Coronaviruses are a large family of single-stranded RNA viruses that cause a wide range of diseases of varying severity. Necessary measures to deal with this disease include hygiene and cleansing of hands, body, clothes, tools and equipment. Ultraviolet light has been used in industry for many years to cleanse viruses, which has been created due to the intense absorption of energy by organic bases in the microbial nucleic acid.
UVC lamps 200 to 280 nm have been used for decades to disinfect, kill germs and viruses in hospitals, and when used, the workplace should be empty of staff because these lamps are mostly 254 nm. They are used that can penetrate the eyes and skin and cause inflammation and pain. However, wavelengths shorter than 230 nm have much less penetration into the skin and will cause less damage. The upper layers of the skin are a natural protector against short wavelengths of UVC rays. Ultraviolet lamps with wavelengths longer than 230 nm are less dangerous than existing germicidal lamps. Far-UVC lamps 222 nm are safe for humans and animals; Because the proteins in the skin effectively absorb this light and are considered a natural protective barrier.
With this UVC, in addition to its antimicrobial properties, it can be used without damaging the skin and eyes of humans and animals, and cleaning and microbializing operations can be performed in the presence of humans and animals.

According to research and scientific evidence, the use of this specific wavelength of ultraviolet light in the design in addition to urban spaces in places such as hospitals, buses, airplanes, trains, train stations, schools, restaurants, offices, theaters, gyms and everywhere Far-UVC can be used, along with other precautions, to prevent the spread of viruses.

Expandability
Secure space alone can be good, but the ability to expand the space can create the potential for user activity and presence safely. The main challenge after the disease is to be present in the city and public spaces without stress, to perform social interactions and make maximum use of urban facilities. Turn it into a virus-safe city.

responsive designs
With the ability of programming and computer architecture with the help of relevant software, we achieved a smart and responsive design. So that when the user approaches the space according to the sensors, the lamps are turned on and by leaving the range of each device, the previous device is deactivated and the next device is activated. In addition to disinfecting the space and users, it also saves energy.

Complete disinfection - radiation from above, below and at an angle
In high radiation, there will be parts that are not irradiated, and this will prevent the disinfection and destruction of viruses from being done properly and completely. For this reason, in the border sections, we considered the ranges in floor construction from the floor upwards and at an angle. This move also increases the user's understanding of boundaries and entry into secure spaces.

These items are designed for outdoor space and the device, in addition to the property of disinfecting the space with ultraviolet light, Aromatherapy, Distribute news and alerts, Play Music, Ambient lighting, Dancing Light, Heating and cooling system to promote Environmental comfort, Group games and entertainment, Creating a suitable space for social interactions & Ability to broadcast lessons and various educational tips for children.

Healing Garden
The garden as a natural place is a safe and enclosed space that people take refuge in for comfort and relief from pain and sorrow. Gardens that can have a positive effect on most people in different ways are called healing gardens. With a well-thought-out design, a garden can reduce stress, nurture creativity and express the soul, and more garden healing means relieving stress and the space's ability to relax, rejuvenate and enhance mental health.

a place for cultural activities
Equipping furniture with books and even audio books to the user's choice and interest, playing music, poetry, motivational messages and advice, scientific and educational tips can help raise the cultural level of users. Education and better understanding of the curriculum, safety and health tips, familiarity with urban and city life along with games and activities for children is another goal of designing different parts of this park.

Balance between sociability and individual privacy in design
Each person, depending on their personal characteristics and mood, decides to be in social or private spaces. It should be noted that users have the right to choose and our design should not limit them. Flexible design according to the tastes and circumstances of each person is a topic that should be used in the design of the play space.

The researchers found that continuous exposure to Far-UVC radiation reduced airborne viruses by 90 percent in 8 minutes, 95 percent in about 11 minutes, 99 percent in about 16 minutes, and 99.9 percent in about 25 minutes. Preliminary results from another study show that Far-UVC ultraviolet light is also effective against SARS-CoV-2 virus. According to research and scientific evidence, the use of this specific wavelength of ultraviolet light in the design in addition to urban spaces in places such as hospitals, buses, airplanes, trains, train stations, schools, restaurants, offices, theaters, gyms and everywhere Far-UVC can be used, along with other precautions, to prevent the spread of viruses.
