Evaluation of the Results of Yerevan State Medical University (YSMU) HOSPITALS’ Landscaping Reorganization According to Climate and Acoustic Level

Abstract

The aim of the presented research was to study the effect of hospital greenery on the noise, humidity and temperature of the air status. The study has shown, that even small green planted areas influence on the microclimate alleviating the temperature and relative humidity of the air on the territory and allow to testify that the rational plantation of MPI (Medical Preventive Institutions) is able to reduce the acoustic level and provide a proper treating-preventive regimen in the hospital. The comparison of microclimatic indices of the planted territory of the hospital area both in the morning and evening investigations has revealed a great difference. Morning investigations, carried out in 2009 and 2010 have proved that compared with the open territory in green plantations the temperature of the air is, on average, lower by 1,8 and 1.4ºC correspondingly. In the evening investigations of 2009 and 2010, on average, the indices studied in the green plantations are by 2,5 and 2 ºC lower compared with the results obtained in the open territory. Yerevan differs for its continental climate and is characterized by stable hot, dry summer, which is of special interest due to the unfavorable influence of the surplus heat on the human organism resulting in the organism overheating and tension of the thermo regulating apparatus function. The study has shown that in the morning investigations, carried out in green plantations in 2009 and 2010 the relative humidity was on average 17,3% and 18,9% correspondingly higher compared with the open territory. In the evening investigations, carried out in 2009 and 2010, the indices in green plantations were on average 6,6% and 9% correspondingly higher compared with those obtained on the open territory. Two-year dynamics, when investigating the acoustic level in different areas of the hospital and adjacent to the hospital territories, has revealed higher indices in Abovyan Street, where the acoustic pollution was the highest. A significant difference is noted comparing the results obtained in Abovyan Street with the ones obtained from the green territory of the hospital and the garden-park zone.
