found to exist among these different factors, the international (Chinese, French, German, Norwegian) team of researchers concluded that «food production during the last two millennia has been more unstable during cooler periods, resulting in more social conflicts,» while specifically noting that «cooling shows direct positive association with the frequency of external aggression war to the Chinese dynasties mostly from the northern pastoral nomadic societies, and indirect positive association with the frequency of internal war within the Chinese dynasties through drought and locust plagues,» which have typically been more pronounced during cooler as opposed to warmer times.»

High air change during cooling periods due to infiltration / exfiltration, duct leakage, and excessive ventilation can lead to elevated interior levels of moisture.

«In analyzing the linkages they [Zhang et al.] found to exist among these different factors, the international (Chinese, French, German, Norwegian) team of researchers concluded that «food production during the last two millennia has been more unstable during cooler periods, resulting in more social conflicts,» while specifically noting that «cooling shows direct positive association with the frequency of external aggression war to the Chinese dynasties mostly from the northern pastoral nomadic societies, and indirect positive association with the frequency of internal war within the Chinese dynasties through drought and locust plagues,» which have typically been more pronounced during cooler as opposed to warmer times.»

High inward flow of moisture during cooling periods can result in elevated energy costs due to high cooling loads, building fabric deterioration from decay and corrosion, and health and safety concerns from mold and mildew growth.

This gives rise to moisture flow by air movement and vapor diffusion from the exterior to the interior cooled area as a result of a higher outdoor vapor pressure than indoor vapor pressure during the cooling periods.

Moisture movement by air leakage (the exfiltration of interior moisture - laden air during heating periods and the infiltration of exterior moisture - laden air during cooling periods) is controlled by limiting air leakage openings, controlling the interior levels of moisture during heating periods by utilizing controlled ventilation (dilution by air change) combined with source control (direct venting of clothes dryers as well as the use of subgrade vapor retarders under concrete floor slabs and bath and kitchen exhaust systems), controlling the interior levels of moisture during cooling periods by utilizing the dehumidification capabilities of mechanical cooling systems, and limiting controlled ventilation to minimum values established by indoor air quality concerns.
