GCN comprises 85 members from 14 countries, working
with innovation projects, implementation of best practice in
planning and building projects, education and, last but not
least, dissemination.We send out a newsletter with an update on
European research and development projects, and, two to three
times a year, we send out a magazine with results from EU
projects and others. Our actual activities involve arranging
seminars and webinars.
On the EGCN website
will
find information on the network’s EU projects – building up a
knowledge database for members so that they can save time and
effort in finding the latest news.
Our members aim to support each other in progressing
sustainable development and sustainable projects. The EU has
the large programmes Intelligent Energy Europe and now Horizon
2020, which have the means to support progressive development.
We participate in and disseminate the results of projects within
these programmes.
We want to use the results of these much more actively for
concrete planning and building, and as a basis for new projects.
Two examples are Green Solar Cities, a CONCERTO project with
great results, and AFTER – about commissioning. You can download
magazines informing you about the projects on our website.
You can also use EGCN as your personal network of city guides,
helping you to arrange and manage contact with actors at the
sustainable ‘scenes’ in the member cities.
Join EGCN and use the organisation to get wiser on the sustainable
cities and buildings in Europe, to exchange experiences with others
working in the same field, to educate, and to make use of us as a
platform for the dissemination of your projects.
Membership is not free, but it is affordable and has a lot of
advantages. Contact us and hear all about it. The Active House
Specifications are useful as a basis of designing the nearly zero
energy buildings of the future, including performance
documentation. See
The Green Solar Cities approach
The main aim of the
Green Solar Cities
publication is to provide
people with a vision of how cities and buildings of the future can
be implemented with high energy quality, with an optimised
energy supply which, to a high extent, is based on renewable
energy, and with an equal focus on how to secure best practice by
introducing a clear policy for performance documentation. This
can be done by looking at experiences showing where the risks of
bad performance results lie in practice.
So the basic idea of this publication is to present examples from
practice, including experiences from the EU-CONCERTO Green
Solar Cities project (2007-2013), to show that the idea of making
low energy buildings is about introducing a quality agenda for
buildings.Without this approach, buildings and large renovation
projects will be built in the traditional manner, which means that
they will leak, be full of thermal bridges and have a poor indoor
comfort. The ‘passive house’ movement in the 1990s, mainly in
Germany and Austria, demonstrated that high quality
constructions without thermal bridges and air leakages, combined
with heat recovery of the ventilated air, resulted in buildings with
almost no need for heating.
When the passive house results were first discussed in Denmark
after 2000, the ambition was to go in the opposite direction and
mainly work with natural ventilation. And since many architects
were used to this, the new passive house agenda was difficult to
understand: “Does that mean we will have to introduce
mechanical ventilation again?”
This was actually the case. However, like introducing passive
house qualities to the constructions, it was very important to
communicate that a high quality version of mechanical ventilation
was needed. In other words: the efficiency of the heat recovery
should be high and the electricity use for the fans should be low.
However, due to a lack of clear standards of documenting these
things in practice, it has unfortunately proved very difficult to
control this. The experience is that it is very difficult to ensure that
a mechanical ventilation system actually has a low electricity use,
unless you can ensure a direct survey of this with the users and
building owners.
This sets a good background for securing the next step of low
energy buildings – buildings with easy access to all basic energy
uses on a direct online basis. This is possible for different
electricity and heating uses, as well as for basic comfort indicators
like indoor temperature and humidity, CO
2
level and even daylight.
The latest Wi-Fi technologies make it possible to obtain proof of
an overall energy quality, documenting that users get what they
have paid for.
