Finnish houses are designed according to old climatic standards, which may cause problems in the future

Due to climate change, rainfall in Finland will increase in the future, so more attention should be paid to protecting houses from rain and moisture. At the same time, warming will lead to higher temperatures, especially in older multi-storey buildings. Changes are required in the design and construction of residential buildings, experts say.

Due to climate change, we must get used to more frequent abnormal weather events, and it is necessary to prepare for this also in the construction industry, experts say.

How is climate change affecting Finnish buildings?

– Average temperature and precipitation are expected to increase. As a result of an increase in the number of cloudy days, the sun will not dry out the material from which residential buildings are built as much, – lists the professor of building physics from the University of Tampere Juha Vinha .

The greatest risk for construction is an increase in precipitation

According to Vinh, more and more attention should be paid to the moisture resistance of building structures in the construction industry.

A stone house, for example, is cool and withstands moisture well. Also, a wooden house is a good alternative, but a wooden house with brick cladding is already a risk, because the brick absorbs moisture well.

It is also important to develop rainwater drainage for houses, experts say.

The inhabitants of the upper floors suffer from the heat

The inhabitants of the upper floors in the old multi-storey buildings suffer most from the heat. The heat does not damage the structure of the building, but it makes the heat in the rooms unbearable.

In Finland, thermal insulation effectively prevents heat from escaping from the building. Therefore, on a hot day, you should not open the windows and let warm air from the street into the house.

It is also important to choose the right exterior wall color, as light walls do not attract the sun’s rays as effectively as dark ones.

– Dark colors are trending now and more and more people are painting houses dark. They absorb the sun’s rays more efficiently, and the temperature in the building rises, says Juha Vinha.

Construction Technician Ilkka Salo advises that at the design stage of the house pay attention to where the onka go

– It’s easy to figure out different options on paper, it’s more difficult to make changes to an already finished building, says Salo.

Finnish houses are designed according to old climatic standards

According to Ilkka Salo, one of the problems of construction is that in Finland, when designing buildings, old data on weather conditions from 1980 to 2010 are used …

– The average annual temperature in the 2010s was significantly higher than the average annual temperature in the last decade of the 20th century. When testing data from 1980 to 2010 is used, the designers do not have all possible means of temperature control at their disposal, Salo notes.

Vinha agrees with Salo.

– Also in the field structural physicists noticed that the data used in the testing did not correspond to the current situation.
