Horrible story about New York School

[Guest guest]

Here is the link to a horrible story about P.S. 65 in New York, which aired

on CBS-NY Channel 2 TV on last night's 11pm news. There is at least one link

to a prior story and other links. This is just outrageous and indicitative

of problems people are experiencing all over the country in public sector

buildings.

Since when is 1,600 ppm of CO2 hazardous to your health. After

monitoring

many homes and meeting rooms with groups of people for CO2, I

believe

this is a false alarm. OHSA states extended time at 5,000 ppm to be

the

upper limit. 1,600 is measure of a low fres air exchange rate. Most

bedrooms with

two adults are +2,000 ppm when the windows are closed overnight. New

state of the

art ventilation systems will be 400 ppm above outside air which may

result in ,1,000 ppm. " What's the

relative humidity? " is a more important question. Schools are

typically

+70% relative humidity during the wet times of the year. Seventy-two

hours

of +80% relative humidity at the interior surfaces goes mold. This is

something to be concerned about. Ideally fresh clean air ventilation

@ 15

cubic feet per minute per person and keep the relative humidity below

50%

provides the ideal condition.
