Three measures to accelerate the implementation of NZEB.

Examples of low-quality construction work and its consequences.

Interaction with developed models: (a) Croatia and (b) partner countries.

Learning about detailing (the impact of thermal bridges reduction, airtightness problems, etc.) by solving problems with confetti creative systems.

The roadmap for increasing the competences in DER by the project Fit-to-NZEB.

Feedback of students on the structure, layout, content of learning materials and the practicality of training course.

Feedback of students on their view on the progress they have made during the course (regarding competences) and preferences on the practical and theoretical approach.

Feedback of students on their view regarding discussion possibilities with teachers and peers as well as the suitability of the time frame to the presented topics.

Feedback of students on their overall view of the training course.

The roadmap for increasing competences concerning BIM and building energy performance.

The three-dimensional matrix of competences for BIM-AEC stakeholders.

Types of construction projects on which participants work on (multiple choice questions).

Typical project value range (no. of responses: 83).

Percentage of training participants who use or intend to use BIM in their companies (no. of responses: 83).

Participants’ experience in BIM (no. of responses: 21 – those who use BIM).

How important is that specific departments and/or Ministries (responsible for energy efficiency in buildings) mandate the use of BIM to encourage its implementation on energy efficiency related projects? (no. of responses: 77).

Does the implementation costs associated with BIM (e.g. hardware, software and training) outweigh benefits from BIM? (opinion from the participants, no. of responses: 69).

Will the companies/organisations be left behind and/or struggle to survive if they do not adopt BIM quickly enough? (no. of responses: 69).

Assessment by the participants in which project benefits specific to energy efficiency will their company achieve as a result of using BIM. (no. of responses: 40).

What do You think about formal education about BIM, advantages of BIM and BIM processes? (without using specific software, no. of responses: 74).

Assess how much can you increase your productivity by using BIM after the training course. (no. of responses: 75).

Assess how much energy do you expect to save by applying the knowledge you gained during this BIM training. (no. of responses: 73).
