This document discusses strategies for transitioning communities to more sustainable energy systems. It begins by showing projections for increasing global temperatures if carbon dioxide levels continue rising. It then outlines some options for decarbonizing energy systems by 2030 compared to business as usual scenarios. The rest of the document discusses various policies, programs, technologies and strategies that can be implemented to promote energy efficiency and sustainable energy, including setting targets, improving building standards, developing new business models, addressing customer perceptions, and promoting technology learning and integration. The overall message is that transitioning to sustainable energy will require a combination of effective policies, efficient programs, and engaging all stakeholders.

Sitra Håkan Axelsson Vattenfall 2012-6-7Sitra Energia
Håkan Axelsson oversees Vattenfall's Sustainable Cities program, which aims to support cities in transitioning to sustainable energy use through energy solutions and coordinated internal and external work processes. The program initially focuses on cities where Vattenfall has a strong presence, such as Uppsala, Berlin, Hamburg, and Amsterdam. These cities account for around 241 TWh in total energy consumption annually, of which Vattenfall supplies around 70 TWh. The Sustainable Cities program seeks to reduce carbon emissions and support cities in achieving their sustainability goals.
The document summarizes the assessment of entries for an ecological building competition. It assessed criteria such as energy performance, material efficiency, and construction costs. The best performing entries were Apila for energy efficiency and lowest life cycle carbon emissions, and Solaris for material efficiency. Overall, Apila had the best balance of ecological sustainability and economic feasibility, as it achieved low carbon emissions and construction costs without major technical risks to implementation. Solaris and Valaistus also performed well but had some challenges with maintenance and feasibility of technical solutions that increased economic and sustainability risks.
The REHVA Task Force proposed a definition of nearly zero energy buildings (nZEBs) based on the Energy Performance of Buildings Directive recast. They defined nZEBs as buildings that have a very high energy performance achieved through efficiency measures and renewable energy technologies. Annual primary energy use should be balanced by on-site renewable energy production so it is nearly zero. The Task Force recommended including all energy uses in buildings in calculations and provided a system boundary definition to specify which energy flows to include.
The Finnish action plan 2010-2017 aims to achieve Finland's 2020 energy targets by 2017 through concrete policy measures across major sectors accounting for 60% of energy use. It includes 31 proposals in 5 key areas: building regulation roadmap, integrated land use planning, on-site renewable energy, existing building retrofits, and R&D. The plan was prepared by a 40-person expert group led by the Minister of Housing and involved benchmarking regulations and incentives in other European countries and impact assessments of proposed measures.
