Green Buildings and the Environment or how to Behave Sustainable

  1. 1. SLOVENSKÁ RADA PRE ZELENÉ BUDOVY SLOVAK GREEN BUILDING COUNCIL THINKING GREEN BUILDING SMART
  2. 2. Why buildings?
  3. 3. How much time do we spend inside?
  4. 4. Over 93 percent
  5. 5. Construction Industry7,5 trillion dollars – global output 2009 100 mil. employees
  6. 6. WHAT ARE GREEN BUILDINGS?•Philosophy: more effective use of resources (energy, water,timber, building materials...)•Goal: reducing negative impact on human health and theenvironment during the whole life-cycle of the building•Through: ideal position and orientation, creative design andconstruction, use of suitable materials, energy and watersavings, building management systems, building site andproject management, recycling of materials Green buildings save Environment & costs
  7. 7. MARKET SITUATIONWorldwide trendEnergy crisis  public pressure  growing socialresponsibility  new corporate strategiesSlovakiaGradual change of perception – brought mainly throughinternational corporations, but also local companiesWhat is needed• owners/users, developers and investors more positiveview on energy efficient buildings• legislative changes and market flexibility 10. júna 2011
  8. 8. EUROPEAN FRAMEWORK EU: 40% of energy used by buildings EPBD II – EU Directive on energy performance of buildings „NEARLY-ZERO ENERGY BUILDINGS“2019 – all new public buildings (or seriously renovated)2021 - all NEW buildings must be „green“Strategy 202020% less emissions of greenhouse gases compared to 1990 +20% less energy + 20% energy from renewable sources(predictions based on current situation – only about 10%)
  9. 9. SKGBC MAIN GOALS Market development in Slovakia towards really sustainable construction Education of experts and public awareness (advantages, market possibilities...) Supportive legislative changes & financial mechanisms (international development, EPBD)
  10. 10. Green Building Councils• Business Driven• Provide frameworks for business opportunity – Definition of Green Building (Rating systems) – Educate and inform• Grow the Green Building market place• Translate the value to governments – Environmental – Waste, GHG, Resources – Energy Supply/Demand and Security – Skills/Jobs/New business opportunities
  11. 11. GBC Network Today
  12. 12. REASONSPolitical pressure – e.g. EPBD IISocial responsibility - consideration towards environment and people (tenants, inhabitants, employees)Economic sense – savings on utilities, higher real estate value ...
  13. 13. SUSTAINABLE DEVELOPMENT (Viable Economies) (Healthy communities) (Natural Environment)
  14. 14. WHICH ONE IS GREEN?
  15. 15. OR THIS ONE... ?
  16. 16. COMPREHENSIVE VIEW Energy savings + Tied to the economy and society + Aesthetic aspect
  17. 17. CERTIFICATES =SUSTAINABLE BUILDING LABEL
  18. 18. Today, we are used to- energy rating of appliances- nutritional values on food...so why not buildings?
  19. 19. Building Certificates Worldwide
  20. 20. Rating Tools:Internationally used (LEED, BREEAM, DGNB)National (Green Star – AU, VERDE – ESP...)Localised versions (Breeam NL, SBTool.CZ...)Building types (Residential, office, business, industrial...)Bureacratic systems (LEED...)Complex and comprehensive (DGNB...)Tentative steps towards a unified systemHarmonisation of sustainable building standards -CEN/TC350
  21. 21. Rating tools consider mainly: Use of resources:  Primary energy  Water use
  22. 22. Also:Quality of Environment Inside  Air quality  Thermal comfort Emissions/Waste  CO2 emissions  Construction waste  Further waste produced (change of purpose, demolition)
  23. 23. RATING TOOLSWhat? Why? How? Raising the quality of construction... Objective assessment… Measurable/Comparable results...A real rise in construction quality?Reflecting time and market conditionsWhat was the starting point?
  24. 24. Not just a marketing?
  25. 25. Seeing is believing
  26. 26. “Architecture is sustainableonly if it is also beautiful!” Prof. Robert Špaček, STU
  27. 27. WHAT IS A PRETTY GREEN HOUSE?
  28. 28. OR...?
