Abstract
Passive ventilation systems have the potential for reduced operating costs in office buildings while maintaining ventilation rates consistent with acceptable indoor air quality. There is a surge of interest in more developed economies for passive ventilation technology but much work is needed before this potential can be realized in sub-Saharan Africa. This explorative study reviews the adoption and adequacy of alternative ventilations systems in office buildings located in the central business district (CBD) of Nairobi, Kenya. Data for the study was obtained through questionnaires and interviews with architects and office building occupants purposively sampled. Thirty four tenants and thirty two architects of these high rise buildings were selected as units of the study analysis. Analysis of their responses is presented using simple descriptive and interpretative techniques. The study concludes that installed ventilation systems rarely meet the needs of occupants and that greater flexibility in ventilation design could provide a measure of individual control of air circulation that would enhance their general comfort.
