  3. Introduction • Energy Performance of Buildings Directive [Directive 2010/31/EU] • subsidies for investorsin„green buidling”, environmentalfriendlysolutions • Strategy for the development of Lower Silesia Voivodeship 2020 (Strategia Rozwoju Województwa Dolnośląskiego 2020) http://supermozg.gazeta.pl/supermozg/1,91628,8267925,Ekodomy.html

  4. Researchmethodology The research studies statistical and real estate data. Research period: year 2011 and 2012 WroclawCounty: Area: 1118 km2 Cities 3 Villages 231

  5. Researchmethodology • The paper closely examines put to use, “green” residential propertiesintheyears 2011-2012. • Thenumber of researchedestatesis 2205, allfromWroclawCounty (Wroclaw city not included)

  6. Researchmethodology

  7. Energy efficient residential buildings PE: numerical indicator of primaryenergy use expressed inkWh/m2 per year „Primary energy”: energy from renewable and non-renewable sources which has not undergone any conversion or transformation process

  8. Energy efficient residential buildings • Criterion PE* ≤ 100 kWh/m2*a Reason: Polishaveragebuilding 145 kWh/m2*a 382 buildingswereidentified *Primary energy

  9. Energy efficient residential buildingsinWroclawCounty PE Primary energy [kWh/m2*a] [Source: selfelaboration , n=382, years 2011&2012, WroclawCounty]

  10. Energy typeusedinthebuildingsinWroclawCounty [Source: selfelaboration , n=382, years 2011&2012, WroclawCounty, multipleanwsers]

  11. Relationbetween PE and Energy performance (FE) [Source: selfelaboration , n=382, years 2011&2012, WroclawCounty]

  12. [Source: selfelaboration , n=382, years 2011&2012, Wroclawcounty]

  13. Number of solutionsinstalledin one building [Source: selfelaboration , n=373, years 2011&2012, WroclawCounty]

  14. Number of buildingswiththecombination of eco-solutions *hrvc- heatrecoveryventilation system [Source: selfelaboration , n=373, years 2011&2012, WroclawCounty]

  15. Number of sold buildings • 8 buildingsintheyear 2011 • 9 buildingsintheyear 2012 http://supermozg.gazeta.pl/supermozg/1,91628,8267925,Ekodomy.html

  16. Obstacles • Lack of data aboutallaspects of thebuildings, only data on energy effectivnessinnewbuildingsisavaluablehence not „green” but energy efficientbuildingswereresearched • EPC’smay not be correct inallcases http://supermozg.gazeta.pl/supermozg/1,91628,8267925,Ekodomy.html

  17. Conclusions • Energy Performance Certificates (EPCs) are not verified • Most of the energy efficientbuildingsarebuild by theowner • Thosebuildingsare not popular inWroclawcounty (17% with PE<100 kWh/m2 per year; 1,86% with PE<50 kWh/m2 per year) • The most popular solutions: biomassburners (fireplaces), solarpanels Source: edgegoodrich.co.uk

  18. Conclusions • More research on thecorrectness od EPCsisnecessary, • Thereshould be moreinformationevaluable on technicalissues of thebuidlings, for professionals and researchers Source: edgegoodrich.co.uk

  19. Futureresearch • Quantifythe energy efficientbuildingsin city of Wroclaw • Research on thevalue of thosebuildingsincomparison to traditionalreal estate • Determinetheaddedvalue of environment friendlysolutions Source: edgegoodrich.co.uk
