Tiivistelmä
In this thesis, a carbon footprint (CFP) assessment is performed on a building during the design phase. The building is planned to be located in Ho Chi Minh City and to function as a fitness center. The goal of the assessment was to determine which building materials and life-cycle stages contributed the most to the environmental impacts. The functional unit (FU) is set as 60 years of 1m2 floor area.
The building environmental impacts were calculated in One Click LCA – a building life cycle metrics software with integrated database from Gabi and Ecoinvent. The building data was taken from Bill of Quantities and Architecture design provided by Intel Corporation – the building owner and Greenviet Consultancy Co., Ltd – the consultant of this project.
The total global warming potential (GWP) throughout the building’s life cycle is 9.32*105 kgCO2eq/FU. Speaking of life cycle stages, energy consumption in the use phase generates the highest amount of emissions, accounting for 56.2% of the total amount, followed by the production phase, with 40.6%. Speaking of building materials, the largest environmental impact is caused by concrete with 2.44*105 kgCO2eq/FU, which is 60% of the total emissions from the life cycle of the building.
In conclusion, the major contributors are the concrete production processes and energy consumption, particularly electricity, during the use phase. The CFP assessment consists of limitations and assumptions; therefore, an uncertainty analysis was carried out for transparent results and possible improvements in future assessment.
