  # Expected value Building Risk Index *
Building Length(m) -
Building Width(m) -

Surface (sq.m):0

Building Heigth(m) -

Volume (cu.m):0

Average persons in building 3 sq.m/person 0.00

Active people require more space than sitting people.

Air Changes per hour 9 0.00

Normally 6 air changes per hour are OK, for coronavirus prevention target should be 9 or more.

Cleanings per week 3 0.00

3 cleanings per week are enough. More cleaning does not change conditions.

Ultra low volume (ULV) fogging per week 3 0.00

This method is equivalent to cleaning, and costs less. 3 per week should be the minimum.

Room Humidity (%) 60% is optimal 0.00

60% is a good value to decrease infection chances.

Total  risk ranking

    0.00

*: Up to 1 for each row is safe, more than 1 is unsafe. A value of 5 for the Total Risk Ranking is acceptable. Higher values mean that the building is too risky.

The building is safe

People density inside buildings is a critical factor. Air circulation and filtering can prevent virus transmission.

Extra ventilation is better than extra cleaning.

The next version will have prices for ventilation and cleaning.
