The use of solar panels on municipal buildings
Rising of the pricesof natural gas, electricity and other media force us to seek for savings.
Recent problems with gas suppliers and make them aware of our dependence on fossil fuels,
which will run out sooner or later, and as more limited they are the prices willrise as a result
of normal market processes.
The use of renewable energy to positively affect the economic balance of a building, as well
as reducing dependence on external supplies of fossil fuels. An additional advantage of the
project is to improve the energy performance of buildings. The heating energy received from
the sunshineby preparing the assessment of the building is recalculated into –socalledprimary fuel. The correction factor is 0. This corresponds to reality, because the collectors
(except for small power consumption of circulating pumps and controls) do not consume
primary energy.
Let us, therefore, their use in municipality buildings.
Clearly, the solar panels are particularly suited to use for heating tap water than for central
heating of a building because the use of hot water followed by the year, and most obtain
energy from the sun during the summer.
To increase the energy gain apart from high season -and this is most of the year (autumn winter - spring)- it is better to use a vacuum tube collectors heat-pipe.
Community buildings are characterized by different water use for the purpose of the hot tap
water provides some examples:
