Environmental Problems in High-rise Building

Introduction

The main purpose of this paper is to make an analysis on the environmental problems of high-rise building. The re-ingestion of toxic or odorous gases exhausted from rooftop stacks of a building may be a cause of indoor air quality problems of the same or an adjacent building. Although many researchers carried the experimental studies out to investigate the dispersion of exhaust from low-rise buildings, they conduct little work on the high-rise buildings (Weber 2001).

Research Question

The present study examines the environmental problems of high-rise building. Although a number of experimental studies have investigated the dispersion of exhaust from low-rise buildings, relatively little work has been conducted concerning high-rise buildings. The purpose of this study is to provide some guidelines concerning the environmental problems in high-rise building (Koebel 2003).

Literature Review

Contamination of fresh air entering high-rise residential buildings can occur if the exhaust plume of the building or a nearby building comes in contact with the air intake (Hadfield 2004). There have been numerous incidents of air intake contamination, although such incidents have not been publicized broadly. The cost of poor placement of an exhaust vent or air intake can be significant (Hourihan 2004). The ingestion of pollutants cannot be completely eliminated. However, the risk of significant intake contamination can be minimized by placing the air intake in the optimum location. Little information is currently available to assist the building designer with the placement of fresh air intakes (Haber 2007). Much of the previous research on dispersion of plumes near buildings is based on wind tunnel studies performed with outlying buildings. A need exists to develop simple guidelines for predicting the influence of nearby buildings on the behavior of plumes emitted from rooftop stacks. As noted in ASIIRAE (1 999), “large buildings, structure's and terrain close to the' emitting building Can have adverse' effects on dilution of stack exhaust because' the emitting building am being' within (he' recirculation flow Zone's downwind of these nearby flow obstacles.

The experience of high-rise housing varies from person to the person between social groups from place to place, and across cultures and time. It has resulted in mixed models of residential satisfaction, and preference studies that do not adequately clarify housing values of residential environments for settings in a society. The concept of high-rise apartments, by definition, is closely related to the number of floors. The effects of living off the ground in a high-rise apartment may impede recognition of the importance of traditional residential benefits such as on street level neighboring or place-identity (Homenuck 2003). Attitudes toward high-rise apartments have undergone a dramatic change. It appears that the volume of standardized dwelling units, their frequent flat-roofed visual uniformity, and the relatively short construction time associated with the increased use of industrial fabrication contribute to lack of acceptance by the general populace. Michelson (1968) reported that eighty-five percent of urban residents preferred Living in single family houses rather than in an apartment (Weber ...
