In Oulu (Oulu city centre health care station), step 1 (proposition of a measure package) was completed two years ago but step 2 (implementation of the measures) did not begin yet. The building owner is looking for new tenants before starting any transformations.
In Tampere (Tampere-Talo conference centre), step 2 is partially complete. The first phase of three renovation phases is over. The new building extension is running and open to visitors. The original glass walls were replaced, improved or replaced by opaque walls, thus improving the building envelope. The lighting system is gradually being switched to LED, the kitchen’s VAC system was fitted with two heat recovery units. Measurements started right after the commissioning of the work in the spring. We recorded a 7 % reduction of the heating energy consumption and 5 % reduction of electricity production for now.
Other measures of the package are being carried out as the second phase of renovation proceeds (creation of a Muumin museum and renovation of the ticket sales area) until next spring. The concerned VAC systems will be updated/changed and a photovoltaic system will be installed on the roof. More data will be available as the planning and the implementation go on.
Additional measures originally not included in the package were implemented, too. So has a share of the roofing bitumen been changed for a white bitumen mix to repel sunlight. In the employee’s areas, water-free urinals were installed.
The third phase of the renovation (administrative wing) will start next year after Finland’s independence celebrations are over. For 2018, several more measures of the package will be implemented. The VAC systems of the concert halls will be replaced and the restaurant’s VAC will be fitted with a heat recovery device. As each phase of the work is commissioned, measurements and follow-up will start.
