Παθητικό Κτίριο και ο Ρόλος της Σκίασης & Ηλιοπροστασίας - Ann Van Eycken

  1. 1. Σάββατο 6 Οκτωβρίου 2012 MEC EXPO CENTER1 E.I.Π.Α.Κ. 2012 ALL RIGHTS RESERVED
  2. 2. Passive House Concept and Solar ShadingFirst Hellenic Conference for the Passive House Saturday 6th October 2012 Ann Van Eycken, Secretary General 1
  3. 3. ES-SO: the European Solar-Shading organization• The umbrella organization of the European solar shading industry• 17 member countries, 1 overseas - US link• Represents thousands of SME’s all over Europe• Offers internal & external solar shading, roller shutters• Acts at European level to demonstrate the contribution of the industry to energy savings in buildings• www.es-so.com 2
  4. 4. 11 full members (national solar shading organizations) - 17 EU countries, 1 US Austria BVST Belgium VEROZO Finland Aurinkosuojaus Ry France SNFPSA Germany ITRS Italy ASSITES the Netherlands ROMAZO Poland Access & Sun Protect. Ass. Sweden SSF Switzerland VSR UK BBSA + Associate Members Euroblinds (Cyprus), Velux (Denmark), CRH (Ireland), Gradhermetic (Spain), Hunter Douglas Norge (Norway) + Supporting Members Sun & Shadow (Greece), De Leeuw Ltd (UK), PAMA (US)
  5. 5. How ES-SO got started•In 2004, the EU authorities were not aware of the merits,markets or even existence of our business•Lobbies of the Insulation, Glass, HVAC etc were very activein Brussels, both at Commission and Parliament level•Since 2002 many initiatives were being prepared forbetter energy performance in buildings•To bring solar shading in the picture, we needed a‘vehicle’ to hook on to and demonstrate our contribution 4
  6. 6. Which EU policy areas to focus on?•Buildings and construction•Climate policy•Energy efficiency and energy services•Energy labeling and ecodesign•Financial, fiscal and tax issues related to energyefficiency 5
  7. 7. Global warming: a complex matter source:jhakkas.wordpress.com
  8. 8. Energy consumption of buildings in Europe: 41%
  9. 9. What is being done in ‘Brussels’ •2002: Initial ‘Energy Performance of Building Directive’ (EPBD) • 2007: Implementation of EPBD in Member States disappointing • 2007: ‘Energy Efficiency Action Plan 2007-2012’ – including the 20/20/20 objective for the year 2020 • EPBD recast in 2010: stricter, clearer, broader, more urgency • 2011: new version of the Energy Strategy for 2011-2020 • Heavy emphasis on refurbishment of existing building stock 8

  12. 12. Our basic message to the EU1. Solar shading reduces the cooling load, saves precious electric energy and helps reduce peak load on the grid2. Solar shading, if properly automated, can reduce the heating load in winter, hence saves energy (automation, roller shutters).3. Solar shading enhances the use of free, natural daylight which reduces the use of electricity for lighting – saving precious power (automatic control, internal solar shading). All products combined, can reduce the energy consumption in the EU’s building stock by almost 10%, according to ES-SO’s scientific study ESCORP-EU25 11
  13. 13. ES-SO’s scientific study: 12
  14. 14. Big energy savings fromreduction of cooling load 13
  15. 15. Use of renewable energy:heat demand reduction from shading 14
  16. 16. Numbers vary with climate zones 15
  17. 17. Energy Performance of Buildings Directive – recast (1)a) All new build “nearly zero energy buildings” as of end of 2020 (public sector: end of 2018). Remaining energy need mainly covered by RESb) Minimum energy performance requirements for all existing buildings that undergo an energy relevant renovationc) Level of minimum energy performance requirements for new buildings (until 2020) and renovations: Benchmarking to achieve cost-optimal levelsd) Requirement for Member States to lay down min. energy performance levels for technical building systems and building elements when installed, replaced or upgraded
  18. 18. Energy Performance of Buildings Directive – recast (2)e) Display of Energy Performance Certificates in public buildings (decrease of threshold to 500 m2 and 250 m2 after 5 years)e) Strengthening the role and the quality of energy performance certificates – i.a. by quality checks and obligatory use of the performance indicator in all advertisements for sale or rentf) Strengthening the role and the quality of HVAC inspectionse) Stimulating financing mechanisms for energy efficiency investments in the building sectorf) Exemplary role of public authorities
  19. 19. Recast EPBD: what’s in it for solar shading?Recital 9: The energy performance should be calculated on the basis of …. and that includes in addition to thermal characteristics other factors that play an increasingly important role such as …passive heating and cooling elements, shading, adequate natural light.Recital 25: Priority should be given to strategies which enhance the thermal performance of buildings during the summer period. To that end, there should be focus on measures which avoid overheating, such as shading and sufficient thermal capacity in the building construction, and further development and application of passive cooling techniques.Annex 1, 3, g: the methodology shall be laid down at least taking in consideration the following aspects such as passive solar systems and solar protection 18
  20. 20. Vision of architects in Europe - 2012 ‘Within the next five years, we will see a trend towards using more natural ventilation and shading instead of traditional air conditioning’ Study Arch.Vision, July 2012 19

  24. 24. Passive House ConceptThe Passive House standard - requirements:• The building must be designed to have an annual heating demand of not more than 15 kWh/m² per year in heating OR to be designed with a peak heat load of 10W/m²• Total energy-use (including electricity) is limited to 42kWh/m²• Total primary energy consumption (heating, hot water and electricity) must not be more than 120 kWh/m² per year• The building must not leak more air than 0.6 times the house volume per hour (n50 ≤ 0.6 / hour) at 50 Pa (N/m²) as tested by a blower door 23
