At the ongoing housing fair in Tuusula, you may come across interesting information on the house boards of the properties. The environmental impact of each house on display has been calculated for the entire life cycle of the building - known for the first time.

The meter is revolutionary.

If the calculation model provides a universally valid, uniform and comparable scale suitable for all buildings, it will revolutionize construction and housing sales in the near future.

Environmental issues are of interest.

Sales of rechargeable hybrid cars have grown rapidly, and many are already considering environmentally friendly solutions in their homes as well: photovoltaics, geothermal and recycling.

When it comes to the environmental impact of the average citizen, housing is a major source of emissions. According to a study by the Ministry of the Environment (2019), household consumption causes multiple greenhouse gas emissions compared to public consumption and investment. Household consumption accounted for 66 per cent, public consumption for 12 per cent and investment for 19 per cent of emissions in 2015.

Mobility accounted for 30 per cent of the carbon footprint of household consumption, housing and related energy use for 29 per cent, food and non-alcoholic beverages for 19 per cent and other goods and services for 22 per cent in 2016.

It is easy to demand a ban on deforestation or peat extraction because of emissions, but yes, every citizen can do a lot on their own.

For example, in his housing.

The building's carbon footprint will become a key factor in home sales in the future.

The emission meter presented at the housing fair works in two directions.

It tells the story of a building’s bad, bad carbon footprint: how much greenhouse gas is emitted by construction and how much it accumulates over the life of the building. In addition, a minus sign, a good carbon handprint, is calculated. It tells you how much carbon is bound by building materials and how much recyclable materials there are in the building.

In addition, the type of heating is specified: district heating, air source heat pump or ground source heat.

But this is important and new: one column in the table shows the total emissions of the building.

One chapter.

In the future, this chapter will guide the housing trade, the formation and construction of housing values. The Ministry of the Environment is currently investigating how the carbon footprint and emission measurement will be integrated into construction.

It is not at all impossible that, in a few years' time, the environmental impact will have to be specified when applying for a building permit. The problem so far has been that a uniform model, the road map, has not been developed and that prevents comparison. The table of the housing fair shows that one can be done. In the Netherlands, a similar calculation model is already in use (Deko 7, 2020).

The Tuusula Housing Fair will present the environmental impact of the house for the first time in its entire life cycle.

The tonnages of emissions do not always tell the average person anything.

For now.

As awareness of the environmental impact grows, even in home sales, people are increasingly asked what the carbon footprint of the property is and what kind of energy solutions have been made. In addition to environmental issues, the readiness for reform is boosted by absurd energy prices. For a citizen struggling with electricity transmission charges and heating costs, the threshold is very low to look for other solutions. Many housing associations and detached houses are already considering environmentally friendly solutions, such as geothermal energy.

As the saying goes, the value of an apartment is determined by three things: location, location, and location. In the future, the rimp will certainly go like this: location, carbon footprint and form of heating.
