The subject of the thesis is to investigate a potential renewable
strategy for the future in Greece. The main concern is to suggest wa ys
for energy saving and minimise cooling energy demands and carbon
emissions in private residences. It investigates the prospect of a more
promising and efficient new development in the field of passive
cooling and low energy cooling. It looks at ground cooling using
earth-to-air heat exchangers but also covers photovoltaic systems. It
determines the possible green electricit y output of PV systems which
could be used for air conditioning.
Initially, an overview of completely natural cooling methods and low
energy methods took place. Moreover information for ground and
solar energy was included for improving indoor comfort and external
environment.
A complete model of a building was created and simulated in an ESPr
enviro nment according to the Greek climate and modern building
characteristics. The building was built very recently and is located in
the suburbs of Athens. The implementation of PV panels and earth-toair
heat exchangers was investigated. The results of the energy
demands and carbon emissions, before and after implementing the
above renewable technologies, were compared and examined. A
validation of the two technologies appeared to make an improvement
in energy efficiency and a reduction in carbon emissions.
