A guideline for COVID 19 free building design

#COVID19 is an infectious disease affecting the human respiratory system. The spread of the #coronavirus is through small droplets from an infected person when he/she coughs or exhales. Other people may catch coronavirus by touching any surface with these small droplets and then touching their eyes, nose or mouth. People can also catch coronavirus if they inhale the contaminated droplets.

In short, to prevent infection, stay away from each other and minimise the touching of any object (if touched, wash hands before touch your face).

The best effort is to stay at home. However, for a public building, what kind of design would be effective to help prevent the spread of Coronavirus? Eventually, this is also a good design philosophy to prevent any virus spread in the future after this COVID 19.

This article discusses the designs that fit the purpose, from the moment we enter the building:

When we enter a building, a good virus-clear-design is to have automatic doors with motion sensors, to avoid touching the door handle #handsfree. If the indoor environment is cooled or heated, this will also minimise air leakage when people do not close the door. (we often see #shoppingmall with big glass doors widely open, trying to cool/heat the entire street).

To navigate within the building, we either use the lift or escalators. You may need to practice balancing on the escalator without touching the handrails. In the lift, a voice navigated system would be good, but there were some errors before, check this out for a big laugh

You only need to make sure you speak the right accent and do not go to level eleven.

A safer way is to tap your pre-registered card to lock in the floor, or an app to command the lift through your phone. At this moment, you may still need to press the lift botton, then go to the washroom to wash your hands.

In the toilet, a sensor flush is always useful, but there won't be an option for a full/half flush to save water. Another possible way is to program something to detect the need to flush half/full? Apologies for sharing too much to imagine. Maybe an easier way is just to flush twice if needed.

The most important part is washing hand frequently, with an auto #sensor handwash faucet and auto soap dispenser.

Stay safe and practice personal hygiene!
