ABSTRACT: Decrease of energy
consumption in buildings and increase of the share of renewable energies in them
are currently technologically and economically feasible and it is promoted by
E.U. policies. After 2019, all the new public buildings in EU countries must be
near zero energy buildings reducing their energy consumption and CO2 emissions. Use of various renewable energies for heat and power generation in
school buildings in Crete-Greece can result in zeroing their fossil fuels
consumption and CO2 emissions. Purpose of the current work is to
investigate the possibilities of creating zero CO2 emissions school
buildings in Crete-Greece due to operational energy use in them. A methodology
which allows the replacement of fossil fuels with renewable energies in school
buildings is proposed. Solar energy, solid biomass and low enthalpy geothermal
energy, which are abundant in Crete, can be used for that. School buildings in
Greece consume significantly less energy, 68 KWh/m2 year, and emit
less CO2, 28 kgCO2/m2 year, than the
corresponding buildings in other countries. The installation cost of renewable
energies systems in order to replace all fossil fuels used in school buildings
in Crete-Greece and to zero their CO2 consumption due to energy use
in them has been estimated at 47.42 - 87.71 €/m2, which corresponds
to 1.69 - 3.13 €/kg CO2 saved.
