The fourth and final public seminar of the research project COMBI was held at the Hervanta campus of Tampere University on Thursday 24.1.2019. COMBI launched in 2015 and the aim of the project was to investigate the ways to improve the energy efficiency of municipal service buildings safely and efficiently. The results from the last year of the project as well as the conclusions and recommendations of the whole project were presented in the seminar. The final report and the recommendation list COMBI 8 were also presented at the closing seminar.

A total of 160 people had signed up to the day-long seminar. The event was open to the public. The participants included representatives from the cities, municipalities, construction companies and building service companies that were a part of the project. There were also participants from other parties working with the construction design, execution and maintenance of buildings. The results from the last year of the project mainly covered the laboratory tests of construction materials and structures as well as field surveys on pressure differences and indoor air conditions of schools and day care centers. Additionally, new research results were presented on the architectural design of windows, the criteria of execution in repair construction, and the utilization of remotely produced renewable energy. The summarizing presentations at the end of the seminar gathered together the principal procedure recommendations related to architecture, structural engineering and building service engineering.

“The research project COMBI has been the single largest project in the history of the Department of Civil Engineering of Tampere University of Technology, when measured by the master budget. The project, which was exceptionally extensive and consisted of many different viewpoints, has well expressed what a diverse subject improving the energy efficiency of buildings is.”, says the responsible director of the project, professor of building physics Juha Vinha.

Along with the original publication, the results of the project have been compiled into short result cards and the related presentation material in hopes that they will ease the implementation of the results. In addition to the 45 result cards, the recommendation list COMBI 8 was composed, which includes the procedure recommendations formed during the project divided under eight themes associated with improving the energy efficiency, cost-efficiency, safety and healthiness of buildings. The background factors of the energy efficiency of buildings and the procedure recommendations are covered in more detail in the final report of the project, which also includes the result cards and the COMBI 8 recommendations as attachments. The final report, the publications of the project and the seminar materials are available to all on the project’s homepage.

Comprehensive development of nearly zero-energy municipal service buildings (COMBI) is a project carried out in 2015-2018, where the research parties were Tampere University of Technology, Tampere University of Applied Sciences and Aalto University. Thirty-seven construction and building service companies took part in the project and its funding. Other parties involved in the project were The Cities of Tampere and Helsinki, Tampere City Region as well as the towns of Nokia, Orivesi, Ylöjärvi and Kangasala, and the municipalities of Lempäälä, Pirkkala and Vesilahti, along with EcoFellows Ltd (Ekokumppanit Oy). The master budget of COMBI was 2.4 million euros. The part of Business Finland (former TEKES) and the European Regional Development Fund in the budget was 1.7 million euros. The coordinator of the project was the building physics research group of Tampere University of Technology.
