Sustainable tall buildings that provide comfortable, healthy and efficient indoor environments are clearly desirable as the densification of living and working space for the world’s increasing population proceeds. For environmental concerns, these buildings must also be energy efficient. One component of these tasks is the provision of indoor air quality and thermal comfort, which can be enhanc...

The applicability of the utilisation factor method EN ISO 13790 is studied in modern Finnish buildings in the cold climate of Finland. The heatdemand results of EN ISO 13790 are compared against a validated dynamic simulation tool. It is shown that, with the default values of the numerical parameters of the utilisation factor, EN ISO 13790 gives in Finnish conditions as much as 46% higher or 59...

Against the background of climate protection and rising costs a fossil-fuel-based energy supply, interest in performance indoor buildings real operation is rising. This paper, therefore, deals with investigation two medium-sized office Germany by taking measurements over whole year. These relate to one new building refurbished building. Sensors various types were installed operated large number...

Office workers' preferences for air movement have been extracted from a database of indoor environmental quality surveys performed in over 200 buildings. Dissatisfaction with the amount of air motion is very common, with too little air movement cited far more commonly than too much air movement. Workers were also surveyed in a detailed two-season study of a single naturally ventilated building....

UNLABELLED Some prior research in office buildings has associated higher indoor temperatures even within the recommended thermal comfort range with increased worker symptoms. We reexamined this relationship in data from 95 office buildings in the US Environmental Protection Agency's Building Assessment Survey and Evaluation Study. We investigated relationships between building-related symptoms ...

“Given the high land values in central business sections of our leading cities, the skyscraper is not only the most efficient, but the only economic utilization of certain strategic plots. An exhaustive investigation... has conclusively demonstrated that the factors making for diminishing returns in the intensive development of such plots are more than offset by the factors making for increasin...

This paper summarizes the results of a large indoor environmental quality survey in office buildings, comparing green with non-green buildings. On average, occupants in green buildings were more satisfied with thermal comfort and air quality in their workspace. However, the average satisfaction scores in green buildings for lighting and acoustic quality were comparable to the non-green average....

This study is aimed at understanding the effect of shapes of floorplates of buildings on office layouts accommodated in them. It constructs a configurational model and proposes that floorplate shapes influence the spatial integration of layouts according to the design principles used for generating the layouts. Gauging the potential of building shells for accommodating various office layouts is...

The behavior of the building and real estate sectors is quite important in matters of environmental sustainability. It is reported, for example, that buildings account for approximately 40 percent of the consumption of raw materials and energy. In addition, 55 percent of the wood that is not used for fuel is consumed in construction. Overall, buildings and their associated construction activity...

The cooling load prediction of heating, ventilating and air-conditioning (HVAC) systems in office buildings is fundamental work for optimizing the operation of HVAC systems. In this paper, an improved multivariable linear regression model is proposed to predict the daily mean cooling load of office buildings in which three main measures, including the principal component analysis (PCA) of meteo...
