Distribution of Urban Green Spaces – an Indicator of Topophobia – Topophilia of Urban Residential Neighborhoods. Case Study of 5th District of Bucharest, Romania

Abstract: Given the lack of usable data in the correct assessment of housing quality in an urban ecosystem, it is necessary to establish a system of environmental indices that can be used to evaluate and compare the attractiveness of urban neighborhoods. Oxygen generating surfaces fulfill multiple functions and give a certain quality to urban environment and housing, especially through the green spaces. Green spaces have an unequal distribution in the area of Bucharest. The structure, functions, adding availability and/or attractiveness of green areas define the neighborhoods in which they are located, and whether they are topophile or topophobe ones. In the present study, based on field observations, processing of cartographic materials and using the green spaces as most relevant index, topophile and topophobe neighborhoods have been identified in Bucharest. The tendency of residential areas development was also evaluated and it was found that it depends on the attractiveness of existing urban parks or neighborhood gardens.

Indoor Air Quality in Bucharest Housings in the Framework of Present Environmental Changes

Abstract: The indoor air quality represents one of the factors conditioning housing quality in urban residential spaces. The paper analyses the spatial and temporal distribution of parameters defining the indoor air quality from representative housings in Bucharest, correlated with their influence factors. The characterisation of permanent, seasonal and circumstantial influence factors was realised using the US EPA (1991) and WHO (2006) methodologies. Between November 2008 and February 2010 there were applied questionnaires for appreciating the dimension of influence factors inside and outside the housings. In the same time, for determining the values of representative indicators analysing the indoor air quality, measurements were realised in selected housings. From analysing the obtained results, it can be stated that in the indoor habitat of most residential spaces from Bucharest, the quality of air is unsatisfactory, values of human comfort recommended by international legislation being exceeded at indicators such as: volatile organic compounds, carbon dioxide or particulate matter. The building’s ventilation systems are mostly dismantled or not functioning, and as a result the thermal isolation of buildings only aggravates these problems as it isn’t compensated with an improvement of the ventilation systems. The significant expansion of areas affected by Sick Building Syndrome, which are economically, ecologically and/or sanitary inefficient, in the framework of recent environmental changes, it requires an integrated approach of problems concerning the air quality management in Bucharest residential spaces.
