Tampere is located on the banks of Tammerkoski rapids, between two lakes, Näsijärvi and Pyhäjärvi. Tampere is the third biggest city and 2nd biggest growth center in Finland and the biggest inland city in the Nordic countries with 232 400 inhabitants.
The EU-GUGLE demonstration takes place in Tammela, which is a sparsely built traditional residential area right next to the city center and the railway. Characteristics are the traditional square plan with building stocks, vivid market square and parks. Tammela has a need for refurbishments and large potential for infill development.
The Tammela district
Tampere has 232 400 inhabitants, the Central Region Tampere has 389 896 inhabitants and the Tammela district, where the renovations take place, has 6337 inhabitants. The age distribution of Tammela is one-sidedly mostly elderly people. 94 % of the inhabitants are between ages 18-over 85 and only 6 % between the ages 0-17. Decision making in the privately owned housing companies can be challenging because of lack of interest to do big renovations and lack of funds.
The renovated buildings in Tampere
The first round of renovation actions in 8 pilot buildings took place between 1.4.2013 – 31.12.2016 and 4 of the buildings did further actions between 1.3.2017 – 31.12.2017. The follow up period lasted minimum a year.
The results of the refurbishment work are presented in factsheets detailing the different stages of the refurbishment process and its measured impact on energy efficiency and renewable energy production.

- Heat recovery of the waste water
- LED lighting in the public spaces of the building
- Building energy management systems for monitoring and remote controlling
- Renewal of the lifts to new energy recovery models
- Specialized events for the residents and the other parties on energy efficient and environmental friendly renovating, building and living
The expected energy savings of purchased energy are 40 %, based on calculations. This far savings have been over 50 %.
The benefits for the various groups affected by the development of Tammela district will be significant. The energy efficient renovation demonstrations will produce environmentally friendly living spaces with a better quality for living, and a format that can be replicated in the specific area as well as in all other areas. The improved quality will also help to save and raise the value of the existing buildings. If the whole Tammela-project will succeed according to the plan, it will provide new modern and energy efficient residence to over 4000 citizens in a green urban environment with good services and connections, at the same time helping the city with the issue of net migration and creating a format for the needed infill development processes. The improvement of the area itself will naturally benefit also the current inhabitants as well as everybody else under the influence.
EU GUGLE district heating and cooling networks
The renovation project can be financed with the housing companies own funds, bank loan and combining different financial models. There are also partial public renovation financing aids as either interest or financing subsidies. The EU-GUGLE project also provides the chosen housing companies with additional funding.
The Tammela housing stock consists of mainly dwellings owned by households (through shares) in housing companies. The Finnish system of housing companies has worked well in new housing production. The system also enabled low-income households to purchase an owner-occupied dwelling. As housing company can get a bank loan for renovations.
Now that the buildings are reaching the age when renovations are needed, the model that was excellent for new construction has proven a hindrance.
The situations of lives of the occupants of housing companies are different. Households may have one or two incomes or live on wages or pensions. Renovation costs are divided based on dwelling size, not the number of inhabitants or their financial capacity.
The owners of dwellings in housing companies are personally responsible for renovations to their dwelling while renovations of the building and technical systems are a joint responsibility. Decisions on renovations require a majority. There are always household-dwelling units in housing companies unprepared for renovation. The reason is often that the occupants only intend to stay in their dwelling for a short period. New hindrances to renovations are the investment dwellings of the elderly who seek additional pension security in the form of rental income. It is often impossible to transfer renovation costs in full to rents, which raises the threshold for renovations.
