22.02, Group 2 — Concept of sustainable development in built environment

  1. 1. Sustainable technologies in building Proposed by Group 2
  2. 2. Contents • Energy problems in building • Our vision of 2030 • What do we need to make it come true? – Technical Solutions – Energy sources – Implementation solution • Economic • Informational • Indicators • Conclusions
  3. 3. Energy problems in building • Dependence on natural gas and masut instead of own and renewable resources • Old heating equipment • Low efficient technologies in municipal heating and electricity supply • Society’s unawareness of new energy technologies • Country’s orientation on fossil fuels on governmental level
  4. 4. February 22,Renewable FOSSILE 2030. FUELS resources Ukraine
  5. 5. Year 2030. Ukraine Electricity production in Ukraine in 2030 10% 10% 20% 60% Nuclear power plants Heat & power plants Hydroelectric power station Biomass energy; biomass fuel cells
  6. 6. Year 2030. Ukraine Heat generation in Ukraine in 2030 Boiler-houses (coal) 10% Biomass energy & waste 20% Boiler-houses (gas) 10% All types of heat pumps Heat & power plants 30% 30% Boiler-houses (coal) Boiler-houses (gas) Heat & power plants All types of heat pumps Biomass energy & waste
  7. 7. Year 2030. Ukraine ü New types of home-used energy (renewable resources) ü Companies specialized on low-energy technologies ü The market of renewable resources ü Ukrainian-made equipment for municipal heating with renewable resources ü System approach in building (passive & active energy technologies)
  8. 8. What do we need to make it come true? Passivhouse Minergie R° LEED We need to follow the best world technologies in building sector!
  9. 9. Energy Technologies
  10. 10. Passive technologies It’s an approach to minimize all energy use, irrespective of the fact that the energy may come from renewable resources. One of the original Passivhaus at Darmstadt, Germany
  11. 11. Passive technologies The dark colours on this thermogram of Passivhaus show how little heat is escaping compared with traditional building
  12. 12. Passive technologies ØPassive solar building design techniques (compact in shape, windows oriented towards the south) ØSuperinsulation ØHeat recovery ventilation ØLow-energy lighting
  13. 13. Passive technologies ØAdvanced window technology ØHeat exchanger ØMicro-heat pump The ability to control building temperature using only the normal volume of ventilation air is fundamental.
  14. 14. Active technologies The production of renewable energy and energy conservation. Examples: BedZET zero energy housing in the UK v Zero-energy house v Plus-energy house
  15. 15. Active technologies Possible sources of energy: §Solar cells §Wind turbines Electricity §Biofuels §Solar collectors §Waste heat from lighting Heating §White goods §Body heat
  16. 16. Space heating Commercial, Private industrial & institutional (single family) buildings houses Existing Existing New New buildings buildings houses houses District heating Ground-source or water- No changes systems (but source heat pumps (with exception of interested home owners) Heat pumps MINIMUM GAS!) Heat pumps (source: sewage water; condensate from power stations) Biomass energy Biomass boilers Solar collectors Boiler houses (coal or gas)
  17. 17. Space heating Commercial & Private institutional houses buildings New Existing New Existing
  18. 18. New commercial & institutional buildings ØGround-source or water- source heat pumps ØBiomass boilers
  19. 19. Existing commercial & institutional buildings ØHeat pumps (source: sewage water, condensate from power stations) ØBiomass energy ØBoiler houses (coal or gas) District heating systems (but MINIMUM GAS!)
  20. 20. New private buildings ØHeat pumps ØSolar collectors
  21. 21. Existing private houses No changes (with exception of interested home owners)
  22. 22. Heat pumps
  23. 23. Why heat pumps?
  24. 24. Why heat pumps?
  25. 25. Biomass potential It is the fourth greatest energy resource after oil, coal, and natural gas. “It can provide approximately 10% of all energy demand of Ukraine (without a share used in other economical branches) by 2015.” According to the Institute for Technical Thermophysics of NASU Especially it can replace natural gas for private houses heating.
  26. 26. Municipal Waste Potential Ukraine has a large potential for using wastes as renewable resource of energy. Waste EU and US example Solid waste Sewages Incineration Anaerobic digestion Electricity District Biogas (70% methane) Heating
  27. 27. Electricity production in Ukraine • One nuclear reactor of 1000 MW performance in case when all this capacity is consumed by heat pumps could substitute 100-120 boiler-houses with average power of 30 MW!
  28. 28. Electricity production in Ukraine What does pollute greater: one reactor or hundred boiler houses???
  29. 29. Why are we speaking about non renewable fuels? Because we try to create a real image. During 30 years, we will not be able to replace all energy by renewable resources. For Ukraine nuclear power is irreplaceable. It will be good back-up system for renewable resources.
  30. 30. System approach in building? Hammarby Sjöstad, Stockholm
  31. 31. Implementation Solutions Educational • Bachelor's and Master's program with scholarships and loans • Special “Renewables” course in all Universities • Holding Ministry contests and providing grants • Participation in regional and international projects • “Using Renewables” subject in secondary school
  32. 32. • Having specialists in designing, implementing and maintaining technologies, using renewables • Public opinion includes need for renewable resources
  33. 33. Implementation Solutions Economical • Establish renewables as the main energetic goal • Provide low interest loans in business, using renewables • Performance-based subsidies, which are clear and understandable • Increased taxation on fossil fuels and decreased on renewables
  34. 34. The market of renewables and connected services Popular use of the renewables in houses
  35. 35. Indicators Number/increase of heat pumps Number/amount of low interest loans, provided for building Number of passive/active systems used Market of renewables and services volume Number of plants producing specialized equipment
  36. 36. Conclusions What we have tried to do during 15 minutes? üExplain our vision of best future for Ukraine üShow the most important mechanisms and technologies to do it. These technologies work in smart countries and should be implemented in Ukraine.
