Integrated system solutions

20/20/20: The Legislation context in Europe It’s commonly known that half the energy consumption in Europe comes from fossil fuels, and that the energy produced in this way causes high emissions of CO2, that is the greenhouse gas known as the main responsible of our planet climatic change.

At present the European Commission is working to implement the 2005/32/CE EUP Directive about products that use energy. We will have the products labelling in the different system conﬁgurations, to set the best global efﬁciency of the heating systems.

Since 1997 the CEE, with the Kyoto Protocol, engaged to reduce the energy demand and, as a consequence, the greenhouse gas emissions, putting in use measures to motivate energy saving and efﬁciency optimization in all sectors interested in energy consumption. The European Commission launched a new campaign for the energy efﬁciency use with the proposal to reduce of the 20% the annual primary energy consumption, and so enhancing the renewable energies use up to the 20%. These target shall be archived within the year 2020.

Integrated Systems The Heating and DHW system evolution The law evolution in Europe, together with the technological product innovation, pushes designers and installers to think system solutions more and more innovative and highly efďŹ cient. In this catalogue Baxi presents some cases describing the installation evolution for buildings with one, two or more living units.

The fast market evolution leads to a growing complexity and to more competitive scenarios. The market request is evolving from a product to a system demand for an efďŹ cient heating of the building. Baxi pays attention to the market trends and proposes some solutions, according to a system approach, adding a service value for the customer.
