Bioclimatic benefits of green areas in a city – Botanical garden in Zagreb

There are many benefits of green areas in modern cities (social, environmental, climatic…), especially of those that are situated within densely built urban areas. Botanical garden of Faculty of Science, University of Zagreb, is placed near the Zagreb city center and it makes a cool island compared to a surrounding build-up area. During summer months the average seasonal temperatures are up to 1, 8 °C lower than in surrounding parts of the city and absolute temperatures are even lower. This research deals with an analyses of data measured by automatic data loggers on eight measuring points in Botanical garden and the surrounding area, as well as data measured in meteorological stations in Zagreb (by Croatian Meteorological and Hydrological Service). Measurements of temperature and relative humidity in Botanical garden have started in May 2018. The goal of a research is to analyze the thermal differences and the differences in bioclimatic conditions between Botanical garden and built-up area. Therefore, bioclimatic indices, as effective temperature and heat index, will be calculated to quantify the favorable thermal features in the Botanical garden, in particular in the warm part of the year when most of visitors spend their free time there. These bioclimatic conditions have auspicious impact on human health especially in the summer months when high temperatures occur
