Driving Energy Efficiency in Swiss Building Renovations: Insights from the Energy Alliance

The Energy Alliance, led by Dr. Pia Stebler, aims to enhance the energy efficiency of Switzerland's building stock. By targeting building renovations, the initiative seeks to reduce energy consumption and CO2 emissions while promoting renewable energy use. Despite the potential to save 15% of energy without compromising comfort, the current renovation rate remains below 1%. The Alliance's "Door Opener" project engages local tradespeople to connect property owners with energy-saving opportunities, showcasing successful pilot evaluations that revealed significant savings potential for various buildings.

  2. Preliminary remark All comments, facts and findings refer to Switzerland. Nevertheless, I can well imagine that parallels exist in other countries.

  3. 10 federal politiciansfrom the 5 mostimportant parties „Energy Alliance, Renovation of Buildings – NOW!“(Political group) „Energy Alliance“(association) 5 federal politiciansfrom the 5 mostimportant parties+ representatives ofrenowned environ-mental bodies andindustry associations Who is the Energy Alliance? Energieallianz(Verein)

  4. Objectives of both organisations? • Reduce energy consumption in buidlings • Cut CO2 emissions • Promote the use of renewable energy How to do? • Parlamentary group: legislation level • Association: projects

  5. about 50%! 1. High share for total energy consumption

  6. 2. Older buildings consume too much energy

  7. 3. To many building in need of renovation

  8. Conclusions so far • Buildings possess an enormous energy efficiency potential!! • It would be possible to save about 15% of Switzer-lands energy consumption • without any loss of comfort and • using the know-how we already have at our disposal today.

  9. Renovation rate below 1%. Why? • 1. Partial failure of the market (external effects) • Numerous players (federal government, cantons,municipalities) • Conflicting objectives in different policy areas • Decision-making behaviour of property owners • Too high capital costs (third-party financing)

  10. Renovation rate below 1%. Why? • Problem relating to beneficiary • Housing demand reacts insufficiently withrespect to energy efficiency • Tax legislation • Lack of know-how on the part of planners,architects and builders

  11. 2009 – The year of the turnaround • „Minergie“ standard is becoming compulsory for new buildings • 100 millions Swiss francs for the promotion of energy-efficient renovation from the federalgovernment • 50 millions Swiss francs within the scope ofeconomic support programme

  12. 2010 – Consolidation • National building renovation programme(cantons) • 200 millions Swiss francs for promotion programmes, financed by the revenue fromthe CO2 fee (earmarked) • A variety of motions relating to tax incentives have been submitted (debate2010?)

  13. Energy Alliance‘s „Door Opener“ project „A very little key will open a very heavy door“ Charles Dickens

  14. Initiative from the basis for the basis • „Door openers“ are local tradesmen. • They actively approach owners of properties in their area. • They do this in an neutral manner, i.e. not as tradesmen selling a specific product

  15. Initiative form the basis for the basis (2) • Property owners benefit in that they receivea rough evaluation about energy consumption for their property. • „Door openers“ show the wayInformations about the options for obtaining financial support / arranging contacts with specialised agencies, i.e. cantonal energy consulting offices

  16. energy factor kWh / (m2a) CO2 emissionskg / (m2a) Content of the rough energy evaluation(extract)

  17. Auszüge aus Auswertung 2(CO2-Spiegel von suissetec)

  18. Experiences with the pilot project • Approximately 300 buildings analysed • In three-quarters of all cases savings potentialsof more than 80% identified • 40% of the owners approached called on theprofessional services of energy consultants. • Process helps maintain (and create) jobs

  19. Thank you for your kind attention.Pia Stebler, Ph. D.Director, Energy Alliance, Renovation of BuildingsMailto: stebler@energieallianz.chPhone: +41 62 824 30 00
