The EU initiative under of the European Commission's Directorate General for Energy started in 2005 and
has co-funded with more than 175 Million 58 cities and communities in 22 projects in 23 countries.

CONCERTO demonstrates implemented examples of:

Innovative technologies that are ready to be applied
The use of renewable energies sources for cities
Energy efficiency measures
Sustainable building and district development
Economic assessments
Affordable energy
Energy transparency for citizens

The CONCERTO initiative proves that if given the right planning, cities and communities can be transformed
into pioneers in energy efficiency and sustainability.

The results so far have been very encouraging: CONCERTO cities and communities have shown that existing
buildings can cut their CO
2
emissions, at acceptable costs, by up to 50%. CONCERTO does this by
implementing renewable energy sources, innovative technologies and an integrated approach.

The 58 CONCERTO cities and communities integrate innovative energy efficiency measures with a
substantial contribution from local renewable energy sources (RES), smart grids, renewables-based
cogeneration, district heating/cooling systems and energy management systems in larger building
settlements. These sets of innovative technologies and measures are optimised locally in order to take into
account the specific characteristics and possibilities of the local site, climate and cultural differences or
local political aspects.

CONCERTO cities and communities demonstrate role models towards zero energy communities. The
experiences and technology performance data from the CONCERTO sites have been thoroughly gathered
and analysed in the meta-projects CONCERTO Plus and CONCERTO Premium. The results are made
available on this website; in reports and via the interactive technical monitoring database with intelligent
inquiry facility. Recommendations for practitioners and policy makers based on the lessons learned in
CONCERTO are particularly relevant for the Smart Cities and Communities European Innovation
Partnership,
which addresses the challenge of making entire cities energy-smart.

The CONCERTO shows cities and communities how to make their energy-systems fit for the future. It helps
the EU reaching its objectives of saving 20% of its primary energy consumption and cutting its greenhouse
gas emissions by 20% by 2020, and by 80-95% by 2050 (compared to 1990 levels).
1.2. Class 1
1.2.1. Introduction
The Municipality of Egedal decided in 2006 to strengthen the energy requirements for a new settlement
called Stenløse South. A total of 442 dwellings was planned to be built in the years 2007-2011 with an
energy demand corresponding to the Danish low-energy standard referred to as "low-energy class 1" ­ or
lower - in this settlement. This means that the energy consumption is to be 50% below the Danish BR08
