  1. 1. Demand response and buildings as active elements in energy networks Miimu Airaksinen, VTT 1
  2. 2. Cities are important • Urbanization is on of the big megatrends (93% of the urbanisation in developing countries) • 78% of European citizens are living in cities(54% globally) • 85% of GDB in Europe (70% globally) is created in cities • 90% of all innovations are cone in cities • At the same time over 70% of all CO2 emissions are originated from cities • In order to avoid negative effects cities need to transform themselves into 'smart sustainable cities'
  3. 3. A city has many systems and sub systems which are interlinked and interconnected • Both system design and operation are in system level, with multi objective optimization • Since many systems are connected the decision making and leadership processes need to change. In addition the business models are in transition (many stakeholders, new eco-systems) Population District Attractiveness Available services and jobs Available dwellings - - Buildings construction + + Demolition Buildings age - + + Births Deaths + + + - + + - Travelled distance- -+ - +/- - Congestion + - - - Roads construction + - - + Energy use Material use Environmental impacts CityPlan Weight factors Material recovery strategies Local energy production Public transport policies
  4. 4. Energy • Over 1.3 billion people lack access to electricity (IEA, 2012 in WWDR 2014, pg. 13). • Globally the energy consumption has increased 31 % in last 13 years (from 2010-2013) (IEA 2015). Household energy consumption has increased 18 % (IEA 2013). The share of household energy consumption varies between regions; in OECD and Asia housing represents 20-30 % of the total energy consumption whereas in Africa the share of household energy consumption is 56 %, Middle East 17 % and in Latin America 15 % (IEA 2013 • In all regions the absolute energy consumption of households has increased, the increase is very modest in OECD and Middle East countries). • The major share of the global energy production is generated from fossil sources

  6. 6. Our energy system is chaging
  7. 7. Energy efficiency is resource efficiency • Buildings consume a high share of energy use in Finland. • The life time of buildings is long, buildings built today will stull stay there after 50-200 years • Building energy efficiency reduces also the peak power demand • Energy efficient renovation is important • The importance of electricity is increasing • Buildings can play active role in demand side management
  8. 8. Lähde: Airaksinen, Vuolle 2012 Also our demand side is changing: Space heating demand in decreasing much more compared to peak power demand =>to decrease peak, smart demand side systems are needed
  9. 9. Future energy networks • Central and decentralized energy production • Integration of local and global solutions • Buildings and mobility system are active part of energy network • Energy network management • Energy storages and smart energy networks • Changing value chains European Technology Platform Smartgrid 2006
  10. 10. Energiatehokkuus on resilienssiä • Suomessa rakennukset kuluttavat energianloppukäytöstä noin 40% ja liikenne alle 20%. • Energiatehokkuus, tarpeenmukaisuus ja kysynnänjousto ovat tulevaisuuden kannalta tärkeitä • Energiatehokkuus on resilienssiä, haavoittuvuus on pienempi ja toipuminen muutoksista nopeampaa • Tulevaisuudessa rakennukset ja liikenne on entistä aktiivisempi osa energiaverkkoa.

  12. 12. District energy optimisation Energy efficiency is resiliency
  13. 13. Tehohuiput vs. mitoitusteho
  14. 14. Total costs of energy system alternatives (30 years) - in 3A and 3B there is a district heating system as complimentary system. - price range is + 20 % (dark part of columns). Huom, ei sisällä järjestelmän operaattorin kustannuksia, oletetaan että taloyhtiö on operaattori
  15. 15. Adaptiiviset ja itseoppivat alueet ja rakennukset DSS Core Performance data and gap analyser Interoperable data services Predictive, proactive and optimising services Optimal performance services Performance New service business Building cockpit Modelling • Ennustavilla ja adaptiivisilla järjestelmillä on eri tutkimuksissa saavutettu 10-30% energiansäätöjä ilman että sisäolosuhteiden laatu kärsii Energy brokering tool
