  1. Energy Agency for Southeast Sweden Energy Efficiency in buildings in Sweden Riga 20061025, Hans Gulliksson

  2. Energy Agency for Southeast Sweden (since 1999) Main Tasks: • Energy efficiency • Conversion to Renewable Energy Sources (RES)

  3. Energy Agency for Southeast Sweden 450 km to Stockholm 240 km to Copenhagen

  4. Energy Agency for Southeast Sweden Responsible Authority: • SSKL, Södra Smålands Kommuner och Landsting Financiers: • Municipalities in the Counties of Kalmar and Kronoberg • SSKL, Södra Smålands Kommuner och Landsting • Regional Council for Kalmar County • Swedish Energy Agency

  5. Energy Agency for Southeast Sweden Priorities Field of activities • Heating • Electricity (lighting and engines) • Transportations • High environmental quality • Reliable energy supply • Cost efficiency • Regional development with increased employment

  6. Core activities • Renewable energy (bio, wind, solar) • Energy efficiency (enterprises, housing, premeises) • Energy Services, Third party financing • Schools and education • Transportations • Energy planning and strategies

  7. Some key-words about ESS • Large network – public & private • Regional information centre • FEDARENE & FSEK • Some 20 projects in EU IEE (SAVE, Altener, Steer), FP5, FP6, InterregIII and structural funds

  8. Some ongoing EU-projects • RES Market Places - IEE • SESAC – Concerto FP6 • SHARE - IEE • WasteWaterHeat - IEE • PU/Benefes – IEE • EuroContract –IEE • Interco/PPP – IEE • E-tream – IEE • MOVE – IEE • Bionet – IEE • eea,ESME,Impulse - RFO

  9. Total energy usein Sweden 395 TWh/year Industry Transports Residential and services Energy for heating and hot water Building etc Electricity for household purposes Electricity for common purposes Source:STEM

  10. Existing buildings New buildings Low-energy houses Delivered energy per heated area (kWh/m2,year) Figure 3. Energy use (delivered energy) for heating and hot water per heated area in multi-dwelling blocks between 1970 and 2002. The graph of existing buildings represents total heated area during the current year and the graph of new buildings shows the energy use when work is finished. Examples of measured values from recently built low-energy houses illustrate the distance to Best Available Technology. (All data adjusted to average weather year)

  11. Existing buildings New buildings Low-energy houses Delivered energy per heated area (kWh/m2,year) Figure 2. Energy use (delivered energy) for heating and hot water per heated area in small houses between 1970 and 2002. The graph of existing buildings represents total heated area during the current year and the graph of new buildings shows the energy use when work is finished. Examples of measured values from recently built low-energy houses illustrate the distance to Best Available Technology. (All data adjusted to average weather year)

  12. Energyefficient buildings – House without heating system - Passivehouse • Strategy: • Minimizing energy losses = effective energy management • Measures: • Very well insulated building envelope • Minimal air leakage • Mechanical ventilation with very high heat recovery • Solar energy for hot water • Waste water recovery

  13. Roof window for airing/natural lighting Solar panel for hot water U-value roof = 0,08 Upper hall Bedroom Clothes cupboard Kitchen Store - Design for optimal solar incident radiation/solar control (winter/summer) - Electricityefficient (A++) domestic appliancies • - Demand-controlled ventialtion • Water.. (vattensnål armatur) • Electricityefficient luminaire • Individual measurement • U-value ground =0,09 • Concrete carcass gives more even temperature • Well insulated external walls and floors -Hot water accumulator -Waste water heat-exchanger Kv.
