  1. 1. _ Mr., Dr. Francesco REDA D.Sc. (Tech.) @frFrancescoReda Clean district heating best practices from Finland and pilots around the world. How smart buildings and districts’ interaction can marry fossil free district heating and cooling networks?
  2. 2. Main drivers and motivation 27.11.2018 VTT – beyond the obvious 2
  3. 3. Climate Change 27.11.2018 VTT – beyond the obvious 3 More Renewable Energy Needed to Avoid Catastrophic Climate Change https://www.irena.org/newsroom/pressreleases/2014/Apr/More-Renewable-Energy-Needed-to-Avoid-Catastrophic-Climate-Change 15 April 2014 limiting global warming to 1.5°C would require “rapid and far-reaching” transitions in land, energy, industry, buildings, transport, and cities. http://www.ipcc.ch/report/sr15/ October 2018 shifting “normals” driven by climate change mean that extreme heat events, water scarcity and increased cooling demand will only become more severe and/or frequent over time. https://www.iea.org/newsroom/news/2018/august/commentary-the-energy-sector-is-feeling-the-heat.html August 2018 Picture: https://www.reddit.com/r/pics/comments/80wu8l/the_arctic_100_years_ago_and_today/

Climate Change: European Union 27.11.2018 VTT – beyond the obvious 4 • The 2015 Paris Agreement (COP 21) • The Energy Union and the Energy and Climate Policy Framework for 2030: reduce greenhouse gas emissions further by at least 40 % • European Climate Change Programme: developing a sustainable, competitive, secure and decarbonised energy system by 2050. Member States decarbonising the building stock, responsible for 36 % of all CO2 emissions in the Union

  6. 6. nZEB Definition 27.11.2018 VTT – beyond the obvious 6 Directive 2010/31/EU(1) defines a nearly ZEB (nZEB) as ‘a building (residential, office, civil) that has a very high energy performance. The nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, including energy from renewable sources produced on-site or nearby’. (1) EU Commission, Directive 2010/31/EU of the European Parliament, (2010) 23. http://eur- lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32010L0031&from=EN. Directive requires all new buildings to be nZEB by the end of 2020 and all new public buildings to be nearly zero by 2018. The Member States must integrate nZEBs in their national plans EPBD, metric to quantify energy use in an nZEB is primary energy expressed in kWh/m2
