To reach the goals of lowering Energy consumption, energy renovation of the current
building mass is an element to reduce the consumption. An initiative to increase the
renovation rate of the building mass can be fulfilled, by establishing network of craftsmen.
Being part of the networks requires a certain level of competencies and awareness
regarding potentials of energy renovation gained through education. Several networks have
been established in Denmark, with focus on creating awareness of energy renovation and
increase the competencies of craftsmen through education. The goal is to increase the
amount of renovation, through decreasing energy consumption. Different initiatives are
established in the networks trying to increase the renovation rate by simplifying the effort
of the building owners to have renovation.

To improve the competencies of craftsmen focus is put on education of master builder,
regarding skills to gain awareness on potential renovation in buildings and having
marketing initiatives. The education helps to increase the competencies of the master
builder and gives knowledge to perform better counseling of the building owners. Further
collaboration between partners in the network has increased the awareness of other
potential renovation assignments. Participation in networks can benefit the collaboration
between craftsmen in the network. The network gives a security for the building owner on a
certain level of skills and the municipal support of networks, gives further trust on the
network by securing a certain level of quality. The focus on marketing and counseling
building owners is helping regarding awareness of renovation potentials for the master
builder.

Networks can increase renovation, but there must be an extra effort from the craftsmen to
increase the renovation rate. Success in the networks comes with an interest in energy
optimization, but it can also be an advantage, having an open approach to increase
participants in the network. The needed change of competencies is mostly regarding
awareness of the climate shell, and focus of new technologies, to gain knowledge of the
potentials on energy reduction. Energy fairs have been a successful initiative and have
increased collaboration between craftsmen, and given increased amount of assignments
from building owners especially free energy counseling is giving more interest of the fairs.
The municipality plays a role giving trust on the craftsmen from the building owners if they
are part of the network, and can help establishing of networks.
