Renewable energy sources are understood as a variety of non-fossil sources of energy. They are called renewable, as they are permanently available and extractable without creating additional CO2 in the atmosphere. For example, the combustion of biomass would only emit the amount of CO2 that has been absorbed during the growing process in a short time cycle.
Therefore, the increasing use of renewables instead of fossil energy resources is one of the two pillars (the other one being energy efficiency) in the concept of reducing greenhouse gas emissions and achieving the climate protection targets.
The availability and potential of renewable energy sources, such as wind, sun, biomass, hydropower and geothermal energy, differ considerably depending on location. Moreover, temporal availability of some of these, e.g. wind and solar energy, is subject to short time fluctuations. For this reason, supplying energy to buildings by using renewables is also often a question of energy storage and distribution
In CONCERTO, an integrated approach of combining the use of renewable energy sources and of low carbon technologies at community level is a main focus.
Low Carbon Technologies
With the help of modern technologies, the energy consumption of buildings can be successfully reduced and the energy sources employed are also used more efficiently. Technologies are called low carbon as they help to reduce the emission of carbon dioxide and other greenhouse gases, which contribute to climate change. With the help of new and innovative products, energy saving potential can be maximized.
Various products are available for the building services of heating, cooling, lighting and ventilation. Either they affect the building envelope to reduce the energy demand (such as insulation or glazing) or they are integrated into the energy supply or its distribution (such as CHP units or district heating networks) to improve energy transformation efficiency. .
In CONCERTO, a key characteristic is the integrated approach of combining the use of low carbon technologies and renewable energy sources on a community level.
You can access the description of each technology applied in the CONCERTO sites and communities:
- by “Search by Map” or by “Search by Technology”
Information about the single technologies will be available in two information categories that differ in their level of detail. The second information level “more detailed” will be available soon.
