The Norwegian Public Road Administration (NPRA) office in Steinkjer, Norway is the first Total Concept project in Norway.

The hand-over process is about to finish and the step 3 measurements has started. The ambition is to reach near passive house level with deep retrofitting of façade, roof, windows and doors, lighting, ventilation and ground source heat pump, for both increased comfort and reduced energy use. The estimated energy savings is about 50 % from 194 kWh/m² to 99 kWh/m².

The picture show the eighteen participants attending Total Concept course in Oslo Norway 11 and 12 of October.

This is the fourth course Total Concept in Norway. In total 67 persons have attended the courses so far. Roughly half of the participants are Energy consultants. The rest are entrepreneurs, building owners, architects, equipment providers and students.

The next course will take place in Bergen the 2-3. of November.

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.

In the pilot office building, Lyngby Port situated to the North of Copenhagen, Step 2 was carried in steps and has just been finished.

The works on connection the building to the district heating has started in Q1 of 2016, but has been delayed due to preparing ground for the coming light rail. It means that the most profitable measure – conversion to district heating can be first fully implemented latest January 2017. There has been also other changes compared to the original plan, e.g. there have been installed centrifugal ventilators instead of axial ventilators, ventilation ducts have been extra insulated then previously planned.

Moreover in one-third of the building, there has been changed the way of supplying air – from traditional VAV diffusers to diffuse air supply over suspended ceiling.

Monitoring and follow-up (Step 3) is currently ongoing. The preliminary results will be known within 2-3 months.

In Estonia, Step 2 has been finished in all of the three pilot buildings and Step 3 is ongoing or is about to start.

In the office building Kiriku 2/4 Step 2 was finished in June and Step 3 will be started in September this year. In Pärnu Koidula Gümnaasium (school building) Step 3 is ongoing including detailed indoor climate measurements. In the last pilot building, Gonsiori office building, Step 3 is also ongoing. Preliminary energy reduction in this building is -6% of thermal energy and -8% of electricity from the periood of 1 January until 30 July. More detailed indoor climate measurements will be carried out to analyze reasons for the difference.

Renovation works are finished in Pärnu Koidula Gümnaasium school building and monitoring and follow-up is ongoing.

Reaching near passive house-level for the Norwegian Public Road Administration (NPRA) Office in Steinkjer with the use of Total Concept method

The Norwegian Public Road Administration (NPRA) office in Steinkjer, Norway is a pilot/case study for Total Concept which is currently in step 2. The ambition is to reach near passive house-level for windows, walls, roof ventilation and artificial lighting, therefore upgrading the building’s energy efficiency. Five major energy efficiency measures are carried out because they are profitable. Total Concept method concludes that investing in a ground source heat pump will not be profitable. However, the property owner Statsbygg plans to invest on this as a measure for improving energy efficiency. , The project includes deep retrofitting by replacement of windows and doors with better U-value of 0,8 W/m2K. Added insulation in roof and walls, upgrading to demand controlled artificial lighting and demand controlled ventilation for both increased comfort and reduced energy use. The project is carried out according to the progress plan with its deadline in October 2016.

The Norwegian Public Road Administration (NPRA) Office in Steinkjer, Norway, consists of three wings built in different building phases; 1967, 1976 and 1984.

From the three pilot buildings in Sweden two of them have proceeded to Step 2 and Step 3. In the first pilot building, Högsbo 20:22 office building in Gothenburg, Step 2 was carried out in summer 2015 and monitoring and follow-up (Step 3) is currently ongoing. The preliminary results show that the savings in electricity are even somewhat higher than expected.

In the second pilot building, Norrtälje prison, two measures out of five have been carried out (change of lighting and replacement of doors) and two measures are currently planned to be carried out (process ventilation and façade insulation). Monitoring and follow-up work in Step 3 is currently planned and will start in autumn.
