dc.description.abstractVentilation as a method of controlling the internal environment in poultry houses serves two main purposes. It provides the desirable levels of temperature and humidity to achieve good poultry performance and it also provides a desired amount of fresh air, without drafts, to all parts of the building. Ventilation also controls ammonia levels to limits appropriate for operating personnel. This paper discusses a simulation model developed to study the dynamic changes of the internal thermal environment in low cost poultry houses in Zambia. The model is based on the interaction of various internal, external and building construction related parameters. The model can be used to predict the temperature in a naturally ventilated poultry house for a given set of input parameters. Furthermore, it can calculate the heating or cooling load required to keep the temperature at desired levels for the birds. It can also be used to study the effects of changing various parameters on the internal thermal environment. The model was validated using data obtained from an open-sided naturally ventilated poultry house housing birds at an average age of 8 weeks. The model was able to predict the internal temperature closely to the measured values. Keywords: Natural ventilation, Dynamic modelling, Poultry housesen
