[Metropolia Student Project Seminar 24.5.] Zero Energy Buildings, Group B

  1. 1. ZERO ENERGYBUILDINGSTony BrickSuresh GurungHyojung Lee
  2. 2. Introduction Researching definition of zero energy building Find new technologies Looking for example zero energy buildings Compare and analyze solutions Summary of the results Suggestions for Finland Conclusion
  3. 3. DefinitionDifferent definition all over the world Similar standards and categories to analyze buildings but still different meaning of each definition by purpose of the buildings and type of the buildings Confuse consumer Combining the analysis of the definition which will have more clear idea of energy consuming efficiency
  4. 4. Examples all over the world Climate Geographical Purpose and aim features Differences Marketing and Living investing style atmospheres Applying Development
  5. 5. Canada
  6. 6. Riverdale NetZero ProjectCanada Location of the project  Edmonton Riverdale Technology used  Thermal water tank  Photovoltaic, heat collecting panels  Heat recovery system of basic housing system Energy performance  Annual energy use 61.51kWh/m²  Annual energy production 63.01kWh/m²
  7. 7.
  8. 8. New Zealand Poor attitude to clean housing Poor housing quality Health and wellbeing  respiratoryillnesses - 50 people a day to hospital  180,000 sick days a year  Cut household power bills with improved insulation and double glazing  Water wastage – enough to fill 9,200 Olympic swimming pools
  9. 9. Little Greenie
  10. 10. Little Greenie Location of the project  Golden Bay Hideaway, Takaka Technology used  Photovoltaic panels  Thermal mass  Solar water heating system  Other feature  Low maintenance  Ease of construction Energy performance  284 kWh/year, normal for NZ is 3040 kWh/year
  11. 11. Zero Energy Building in U.S.A. U.S.A. is adopting more the zero net site building followed by LEED (Leadership in Energy and Environmental Design). In those buildings the amount of energy provided by on-site renewable energy sources is equal to the amount of energy used by the building.
  12. 12. Example dwellings of zero energy building in U.S.A.  Net Zero Energy School Building, Los Angeles, U.S.A.  Holcim Silver Award 2011 North America 
