The Construction Design Weather (RAMI) project was launched in spring 2021. In the project new design conditions have been defined for the calculation of the thermal and humidity performance of structures and the cooling capacity needs of rooms during the summer.
In terms of building physical design years, the project is a continuation of the FRAME project carried out in 2009–2012, which for the first time determined the design conditions intended for the Finnish climate for building physical calculation analyses. These building physical test years selected in the FRAME project will now be replaced with new design years in accordance with the RAMI project.
The analyses related to the frost stress and corrosion risk of facades included in the FRAME project have also been updated in connection with the RAMI project.
Test years for energy calculations have been available in Finland for calculating the heating and cooling energy consumption of buildings, but these are not intended to be used for the design of indoor conditions and systems. In connection with the RAMI project, design conditions for room temperature and cooling capacity that are suitable for the Finnish climate conditions have now been determined for the first time.
The Design Weather for Construction project has utilised the results of the Finnish Meteorological Institute’s RASMI project, which has included hourly time series based on observations from the past observation period 1989–2018, as well as projections based on climate model forecasts for the 30-year periods around the years 2030, 2050 and 2080. These datasets have been supplemented in connection with the RAMI project about longwave radiation downstream from the atmosphere.
A final conference on the project, open to the public, will be held on Tuesday, 31 May 2022 from 9 am to 12 noon. The final conference will be held remotely using the Microsoft Teams program. Participation does not require pre-registration. The link to participate in the event can be found in the attached pdf invitation to the final conference and at the end of this news. The final conference will be recorded and can be viewed later after the conference has ended.
The Design Weather for Construction (RAMI) project has been carried out by the Building Physics and Structural Repair and Life Cycle Engineering research groups at Tampere University, the Energy Efficiency and Energy Systems Research Group at Aalto University, and the Climate Change and Extreme Weather Phenomena research group at the Finnish Meteorological Institute. The project was coordinated by the Building Physics Research Group at Tampere University. The research project is funded by the Ministry of the Environment.
The project’s final report and design materials will be available on these pages when the final report is completed.
