1 Royal Academy of Engineering Sciences IVA was founded in 1919 the first Academy of Engineering Sciences in the world Mission To promote the engineering and economic sciences and the advancement of business and industry for the benefit of society Bo Normark Chairmen Electrotechnology

2 IVA project An Energy efficient society Develop Sweden 50 percent more efficiency 2050 Foundation A more efficient usage of resources, including energy, forms the basis for financial growth and sustainable development. A more efficient energy usage contributes to a reduced impact on the climate, the environment, and leads to a more secure energy supply. Important factors Sweden has formed a goal of reduced the energy intensity in order to achieve energy efficiency. The EU-commission has decided on a new directive with long lasting demands on energy efficiency. Technical development in the energy efficiency area is rapid. The project Identify opportunities and obstacles, and suggest tangible measures for change in different sectors. Identify new business models and business opportunities ABB, Elforsk, Energimyndigheten, Fortum, Humlegården, Ångpanneföreningensforskningsstiftelse, SBUF, Siemens, Skanska, Svensk Energi, Svensk Fjärrvärme, Svenskt Näringsliv, Teknikföretagen, Vattenfall

3 Project organisation and reporting Project Control Group Pre-projects, staffing of project control group, working groups and experts Project leading Communication Evaluation of projects Gathering of data, analysis and presentation of experiences from other nordic countries, Northern Europé and Internationally.

4 Energy use in the residential and service sector Swedish buildings: Reduce specific energy consumption by half in 2050 compared to 1995.

5 Building Categories Houses Facilities Appartment buildings

6 Energy use in the residential and service sector Total annual energy consumption in Sweden: 400 TWh All buildings: 150 TWh

7 Final energy use in the residential and service sector, , TWh Eliminate dependence on oil in focus!

8 Total energy use (temperature corrected energy usage for heating and hot water) kwh/m 2,

9 Age of apartment buildings stock

10 Is it profitable to increase efficiency? 3-4 % return - a typical example in an apartment building But with increasing energy prices and increasing comfort demands, comes an increased long term return and it s sustainable Energy prices over the last 10 years have increased CPI. But will this continue??

11 Observations The property owners who are succesful in their energy efficiency programs provide clear leadership and regard energy efficiency in their buildings as a strategic opportunity The work on an ongoing basis on improving operation and coordination energy measures with renovations as they become nesseary They realize that long-term measures do not always provide results immideately but bring savings over a long peroid and create value

12 Results for building sector Building sector has a high energy efficiency potential Bottlenecks Competence for energy efficiency insufficient Construction rules are not state of the art Lack of financing Opportunities Better initiatives for energy efficiency initiatives e.g. credit risk insurance Small scale energy production Building Energy Declaration Renovation program of apartment blocks built in the 60:ies and 70:ies

13 Recommendations Tighter regulation for renovation and new construction Adaption of preservation standards More stringent energy-use document requirements An analysis of credit risk insurance for energy efficiency improvements Dissemination of information and experience through demonstration National competence improvement in energy efficient construction, Renovation Center R&D program in energy efficiency in buildings

14 Sweden, Energy production from heat pumps Ground Source about: 13 TWh Air to Air About: 12 TWh Total 25 TWh (6% of total used energy) Försäljningen av värmepumpar i Sverige Luft luft* Slutna vätskesystem Frånluft vatten Uteluft vatten * Då inte alla som säljer luft luftvärmepumpar rapporterar försäljningsstatistik, har SVEP gjort en bedömning av den totala försäljningen av luft luftvärmepumpari Sverige.

16 Annual Energy 2012, kwh Efficient household appliances

17 Annual Energy 2013, kwh Heat Pump + Electric Car

18 Akademiska Hus Area Heat El Original Target: 40 % reduktion ,8 million sqm 430 GWh 430 GWh 2012 Result Heat 31% ; Electricity 18% ; Overall 25 % New Target % reduction

19 Heat / Cold Storage

20 Example New Building South Sweden Värme W/m Tillsats 8 kwh/m 2 år Värmepump 75 kwh/m 2 år Värmepump i värmedrift 3 kwh/m 2 år Eleffekt W/m 2 Kyla W/m Direkt från mark 25 kwh/m 2 år Värmepump i kyldrift 2 kwh/m 2 år timmar/år Elenergi för värmepump 19,6 kwh/m 2 år timmar/år

21 Summary Decarbonisation, Energy Efficiency and Energy Independence targets do not necessarily giving same result System approach is fundamental, and energy efficiency potential in buildings is significant Conditions vary significantly between markets based on local conditions Incentives are important but also making alternatives less attractive Do not underestimate the power of consumer willingness to invest under the right conditions, things can go fast Heat pumps and District Heating based on biofuel and waste are central transformation technologies in Sweden
