The use in metropolitan cities of increasing numbers of skyscrapers in which stack effects are large and entrance traffic heavy calls for a better design of entrance for controlling both infiltration and traffic. Analyses the causes of infiltration, discusses the effect of various parameters, presents design charts for estimating heating and air conditioning loads through swinging-door and revolving-door entrances. Introduces a new design of entrance, the travelling entrance-way, and gives approximate method for calculation of air infiltration through it. Compares the new design with conventional ones
