Situated in the Tammela district of Tampere, this 20-apartment building was part of a specific effort to devise a replicable methodology that could inform district level regeneration.  For a modest outlay the works led to a 69% decrease in energy use.

This building had a G energy rating before works commenced – the worst rating possible.  The anticipated energy savings for the works was 50%, but Project Tampere has exceeded that and achieved a real saving of 69% on its energy use.

Tammela is a sparsely built traditional residential area right next to the city centre and the railway.  It is an area where there is a huge need for energy renovation and regeneration, but this has been hindered by the fact that privately owned housing companies are often reluctant to undertake big renovations because of a lack of tenant interest, and a lack of available funding.  Energy renovation costs are divided based on dwelling size, not the number of inhabitants or their financial capacity, which causes many issues in terms of getting people interested in renovation works.  In the case of this building, it took some time to secure agreement among the occupants, but all agree that the result is worthwhile.
