An Investigation of the Greenhouse Gas Emissions in European Countries Buildings According to the Life-Cycle

In this study, greenhouse gas emissions such as carbon dioxide and nitrogen oxides for Bruxelles, Sofia, Prague, Berlin, Madrid, Tallinn, Helsinki, Paris, Athens, Budapest, Rome, Amsterdam, Oslo, Warschau, Stockholm, and Ankara cities in Europe were calculated for ten periods according to the life cycle. The heating and cooling loads of these buildings were determined according to the heat transfer coefficients for external wall, floor and ceiling and heating degree day and cooling degree day values. Natural gas and electricity was examined as fuel during the heating period. In the cooling period, emissions from fuels used in electricity generation were taken into account to supply the electricity need. Natural gas and coal was accepted as an energy source. When determining the heating degree-day value, the base temperature value was accepted as 19.5
⁰
C and for the cooling temperature-day value, base temperature value was accepted as 22
⁰
C. For European countries, calculations have been made for each gas emission taking into account the 20-year values (1998 to 2017) and rate of annual change. As a result, the lowest nitrogen oxides emission (NO
_X
) value for ten years of the life cycle was calculated in Talinn, Estonia as 0.674 and the highest was calculated as 1.328 for Berlin, Germany. Carbon dioxide emission value for ten years of the life cycle is the highest for Stockholm in Sweden by 2.275 and the lowest was calculated in 0.722 with Turkey's capital Ankara.
