Tiivistelmä
High demand for construction projects’ environmental impact limiting resulted in the need for setting up benchmarks for buildings in Finland. Today the global aim of reducing the emissions and hindering global warming is the top priority for most of the countries in the world. Constructions make up a significant part of emissions and are included in plans on impact reduction as one of the key issues. The aim of the present study was to create reference and limit values for constructions of different types in Finland.
Data containing information on building projects was analysed using quantitative methods. Literature review was applied for background information search. The existing data on the study issue was found first, followed by analysis of the data provided by commissioner.
The analysis of the theoretical and numerical data was performed. The environmental impact benchmarking and limit values for building projects were set for use of the commissioner as part of life-cycle assessment online platform as well as for benefits of other interested parties allowed by the commissioner. The set limit for all new buildings is 7.7 to 9 CO2 e/m2/y or 540 CO2 e/m2 for the whole building’s life-cycle of 50 years. The benchmarks and limit values are available for both new and renovated buildings and are also set for construction stages. A significant difference in values and data assessment methodologies between the Nordic countries was found.
