For students of medieval proportional systems who lack such documentary evidence as James Ackerman had, in relative abundance, for his groundbreaking 1949 study of the Cathedral of Milan, the only choice has been to turn to the buildings. Yet Ackerman warned that such an exercise was destined to fail: ‘the analysis of remaining monuments,’ he wrote, ‘provides insufficient evidence for [the] tas...

Ventilation in cities is crucial for the well being of their inhabitants. Therefore, local 1 governments require air ventilation assessments (AVAs) prior to the construction of new buildings. In 2 a standard AVA, however, only neutral stratification is considered, although diabatic and particularly 3 unstable conditions may be observed more frequently in nature. The results presented here indic...

This paper deals with the development of a simple urban model for flow and dispersion in the urban canopy layer (UCL). The flow module of the model calculates spatially-averaged wind profiles adopting a technique recently proposed in the literature, which is based on a balance equation between the obstacle drag force and the local shear stress. Spatially-averaged wind profiles are used as input...

Indoor air quality (IAQ) was investigated in 19 open-plan offices and 30 office rooms in order to compare the differences in these two different types of office environments. No moisture or mold problems had been reported from the present buildings, but the employees had complained about the IAQ. The results revealed only slight differences in the IAQ of the two different types of office enviro...

The Kyoto Protocol and the European Energy Performance of Buildings Directive put an onus on governments and organisations to lower carbon footprint in order to contribute towards reducing global warming. A key parameter to be considered in buildings towards energy and cost savings is its indoor lighting that has a major impact on overall energy usage and Carbon Dioxide emissions. Lighting cont...
