    The maximum tpma (out) must be under 33.5 degrees Celsius and indoor temperature of 31% of the tpma (out) plus 21.3 degrees Celsius. For example, the tpma (out) 33.5 degrees Celsius, the indoor temperature shall not be over 31.7 degrees Celsius. If tpma (out) is over than 33.5 degrees Celsius then a mechanically conditioned space would be in place.

[9] [better source needed] However, the discussion about the opposite experimental results is still going on. [10] About 100,000 Bq/m 3 of radon was found in Stanley Watras's basement in 1984.
