1 Finnängen Swedens first renovated plusenergy house The path to energy-neutrality Andreas Molin Linköpings Universitet

2 Agenda Energy efficiency measures at Finnängen Why?

3 Finnängen before renovation

Exhaust air + Firing Heating Hydronic Bio-mass pellet Space heating demand kwh/yr Domestic hot water demand kwh/år Electricity kwh/år Household kwh/år Building electricity kwh/år

5 Finnängen Hydro power Grid Photovoltaic - 10 kw-68m 2 Solar Thermal - 11m 2 Ventilation Horisontal ground coil 200 m HRX Solar tank-800l Heat pump-6kw th Seasonal heat storage- Ground coil-100 m Insulation 25 cm Air-tightness Windows

6 Air-tightness is acheived by membrane 0,3 ACH (0,13 l/s,m 2 ) at 50 Pa Passive house standard: 0,6 ACH (0,3 l/s,m 2 )

7 Thermal comfort - windows Comparison surface-temperature 10 C out Older Newer 16 C 20,5 C Thermal comfort important when doing energy efficiency measures. Otherwise rebound-effect

8 Grey EPS Lambda 31 mw/mk Long service life & form stability

9 Smart heat storage Use super-heating of the heat pump condenser No need of electric resistance heating for hot water Heating with low primary temperature gives high SPF Low primary heating temp. : Increased insulation Better air-tightness Increased convection area Ventilation heater Can be used for increased perfrmance in District heating systems Lowers return temperature = higher electricity/heat ratio Potential SPF 5 Condensation at 30 Hot water becomes C. No legionella problems

17 Heat pump commisioned

18 Life-Cycle Zero Energy Buildings (LC-ZEB) Embodied energy Operational energy use + embodied energy = 0 Operational energy use must be negative. Finnängen 7000kons-9000prod=~-2000kWh/yr LC-ZEB will be acheived after certain years (ex kwh/ kwh = 50 år) Focus will be choice of materials & service life Older buildng embodied energy must be handled Competition: Which building will first be LC-ZEB?

19 Agenda Energy efficiency measures at Finnängen Why?

20 Why all the Kyoto-pyramid at once? Air-tightness must be planned Finding more development making use of the old building Renovation plan: make efficiciency measures when maintenance is needed & plan for air-tightness

21 Why LC-ZEB on 150m 2? -Biofuels needs vast amount of land -Affects the nitrogen cycle when combusted -Bio-diversity loss with bio Planetary boundaries: Exploring the safe operating space for humanity Rockström et al, 2009 Rockström et al, 2009

22 Why solar power on building => decreased biodiversity loss Solar power= minimum pollution = no effect on nitrogen cycle Building solar power= nonexploiting = no effect on biodiversity Good potential Roof & facades in Sweden: 660 km 2 PV power: TWh, Depending on system efficiency, demanded rate of return. (Kjellson, 2000)

23 Öre/kWh Problem in Sweden: Sold electricity is less valued due to tax Elpris 50 Köpt el Moms Elnätavgift Elcertifikat Annual net-billing => Uses the full roof=> 40 Todays system Decreased exploitation 20 optimises economy for energy=> small systems Decreased bio-diversity 0 loss Energiskatt Såld el Nätnytta Elforsk 10:93

24 However: Higher value of solar power than average power A. Molin, P. Rohdin, B. Moshfegh. +2% +11% Positive power market value for gridconnected roof-top solar power in Sweden. 11th World Renewable Energy Congress and Exhibition, Abu Dhabi, United Arab Emirates, September Similar to Carbon Savings: Night-time lower price +23% An investigation of the impact of time of generation on carbon savings from PV systems in Great Britain. P. A. Burgess 1,*, M.M. Vahdati 2, D. Davies 3 Daytime higher electricity price
