Abstract

Heat has become a common problem in construction industry production and timing in Baghdad region which consider as arid zone. However, construction industry management engineers have no assessments tool to evaluate their planning impacts on the productivity, especially the impact of productivity due to the chance of heat. This paper discusses the development of an empirical assessment for heat prediction to evaluate the impact of construction product. Empirical model of minimum, maximum and mean ambient temperature for Baghdad have been developed and validated, based on the long term field measurements between the period of January 2001 and March 2012. The independent variables that were used in the models are daily minimum, maximum and mean temperature at the reference point, average daily total solar radiation, building area percentage over radius 50m, 100m and 150m surface from the building center, average building height to area ratio, total wall area to green area ratio, sky view factor, and albedo. Sensitivity analyses were carried out to observe the dependence of air temperature due to the variations of each variable. An ideal type construction manufacture was used to simplify the variation of manufactory body, world field green field distribution. The sensitivity analyses were carried out by varying some of the following important parameters; green land cover density), manufacture building height, wall area, work field area which effect the incoming solar radiation (sky view). The screening tool for work place was developed with the motivation to bridge between research finding, especially the air temperature prediction models and the construction management engineers.
