- Abstract
- Air exchange measurements were carried out at the National Archives Building under various combinations of temperature and wind speed. The average air exchange rate under normal operation of the heating, ventilating, and air-conditioning system (HVAC) was 0.9 h to the minus 1 for an average temperature difference of 11.3C and an average wind speed of 2.7 m/s. This rate is approximately twice those for new General Services Administration (GSA) office buildings. No clear dependence of air exchange rate on temperature differences up to 17C or wind speeds up to 5 m/s was found.
