Energy Self-Sufficient Areas, a case study on the Vaasa Housing Fair
2008 (English)In: Proceedings of the Renewable Efficient Energy Nordic Conference, Vaasa Finland, July 9-11 20, 2008Conference paper (Refereed)
EU has targeted 20% renewable energy use by 2020 which has put great pressure on themember states to change energy production, and to use the energy in the most efficient way.New concepts are needed and state-of-the art solutions need to be much more wildly applied.One concept is energy self-sufficient initiatives. There are a number of such initiatives inEurope. One of the most recent ones has been established in Finland at Vaasa Housing Fairopening at July 11, 2008 demonstrating first time innovations and new developments andcombinations.Used technology at the Housing Fair in Vaasa, Finland 2008 is:• A fuel cell power plant running on biogas• Combination with a micro turbine also running on biogas• Utilising sea heat from piping submerged under the sea bottom with a novel technique• A low temperature district heat network directly providing low temperature heat andcooling to the houses• Passive building utilising state-of-the art solutions applicable for large productionvolumesThe housing fair consists of 42 single-family and small houses and 3 apartment houses. Inthis paper we will introduce the used energy supply technology. Based on official informationfrom a pilot study of design conditions conducted by the Geological Survey of Finland andthe technology suggested for the fair, the self sufficiency has been estimated. We concludethat there are reasonable conditions for self sufficiency in both heat and power for at least90% of the average year.Preliminary calculations show an energy self sufficiency of 120% for electricity and160% for heat. The calculations are using specific consumption values based on experienceas declared in this paper.The system is target for measurements, follow-up will be performed and the benefits and possibledrawbacks evaluated in further research.
