A conference at the University of Architecture in Sofia presents the results of the Horizon 2020 project Train-to-NZEB

Nearly 900 construction specialists have been trained by the Bulgarian Building Knowledge Hub (BKH), situated in the University of Architecture, Civil Engineering and Geodesy (UACEG) in Sofia. The courses are conducted along more than 20 innovative training programs, addressing topical issues from the Bulgarian and European construction practice.


In short, these are the results from the EU-financed Train-to-NZEB project, which will be presented at 10:00 am on November 9th, 2018 in Conference Hall 311 of UACEG at an event with the participation of the project leader EnEffect, the partners from the Bulgarian Construction Chamber, the hosts, representatives of the Chamber of Architects in Bulgaria, Bulgarian Association for Insulation in Construction, commercial companies and training centers working in the construction industry. The main question, however, is how these efforts are to be continued: in the view of the new requirements for energy efficiency and RES in new buildings in force since 01.01.2019, and the (currently) active state policy for energy efficient renovation of the existing buildings.


One of the main highlights of the project is the new training and demonstration center at UACEG – the Building Knowledge Hub - which demonstrates all the modern technologies, products and materials needed for the construction of nearly zero energy buildings. The center is equipped following the model of leading training centers in Ireland and Germany. It is part of a network of 10 similar training laboratories in Bulgaria, Romania, the Czech Republic, Turkey, Ukraine, Italy, Greece and Croatia, which aim to create the best possible conditions for specialized practical training of specialists in all areas of the investment process - researchers and designers, investors, site managers and contractors, and of course, construction workers.


The topics underlying the training plan are extremely diverse - from the internationally recognized certification schemes of the Passive House Institute (Darmstadt, Germany) to programs for acquisition of nationally recognized qualification and short demonstration courses. All nZEB-related topics are covered - insulation systems, energy efficient windows, ventilation with heat recovery, airtightness, modern heating and cooling systems, RES, deep energy retrofit of existing buildings, and many others. With the developed international partnerships and the new Fit-to-NZEB project (, the BKH is expected to become a focal point for knowledge and skills sharing for the design, construction and operation of energy efficient buildings that already meet the standards of the coming decades.


The registration for the event, which is a part of the European Week of Vocational Education and the International Passive House Days, is available at and via Facebook at
