Erratum – Minimising airborne TVOCs (total volatile organic compounds) from all sources - KBCN1397

The benchmark for 4.1 Criterion 10 should reads as follows: The TVOC concentration in indoor air is measured post construction (but pre-occupancy) and does not exceed 0.5 mg/m3 (500 µg/m3), averaged over 8 hours.(41) Reference 41, HM Government Approved Document F Ventilation 2010, sets a lower threshold, however for the purposes of HQM One, the threshold stated above is correct. This will be corrected in the next reissue of the technical manual.
