Manufacturing industry of solar heating water system (SHW) and Solar energy cooling system in buildings
Topic of the practice
Solar heating water systems; thermal energy
Good Practice Information
Solar heating water systems (SHW) produce domestic hot water (thermal energy) by exploiting sun radiation. This is a very extended good practice in Crete which has already provided tangible and measurable results. It is “a success story” for the Region of Crete with 400.000m2 of solar termal collectors already installed. Moreover, some pilot solar energy cooling systems (an advanced technology of SHW system) covers climatisation in buildings in summer by using solar thermal energy. Historically the great penetration of solar thermal systems in Greece is a result of a national initiative that took place 25 years ago, and a success story at European level. The solar thermal manufacturing industries represent 22 local manufactures, supplying a very important percentage of the local needs, while others proceeded also to some exports in Mediterranean Countries. Projects of technology transfer, product certification and integration of innovation have been implemented by the Greek Research Center ‘Democritus’ in order to extend the traditional use of solar thermal systems, establish rigorous quality control and certification and facilitate the sector's competitiveness and exporting capacity. Solar heating & energy cooling systems are a source of thermal energy by exploiting the power of sun. This measure promotes reduced dependence on conventional energy sources and zero release of pollutants into the atmosphere. The main problems arising from the increased energy (electricity) use in buildings for heating/cooling water are relevant to the subsequent increase of CO2 emissions contributing to climate change. Solar heating and cooling systems are expected to increase the overall capacity of the existing power production system. Besides, increased temperature and the augmentation of hot days during summer are expected to decrease the energy efficiency of the traditional power production systems which should be alleviated and adapt to renewable and less polluting energy sources. Additionally the production of solar thermal energy is cheaper.
Evidence of success
In Crete there are 400.000m2 of solar thermal systems installed and more than 22 local manufactures supplying a very important percentage of the local market that covers the needsfor water heating. New applications in progress proceed to exports and/or move to the solar energy cooling system in large hotels. Thus, the sector provides over 200 direct and indirect jobs with a very significant turnover and a very positive energy and environmental impact (reducing the combustion of fossil fuels and electricity in private houses, tourist facilities, public buildings and some industries, which subsequently corresponds in a significant reduction of carbon dioxide emissions and climate change).
