Thinking green. Building smart.

1. SLOVENSKÁ RADA PRE ZELENÉ BUDOVY
SLOVAK GREEN BUILDING COUNCIL
THINKING GREEN
BUILDING SMART

2. Why buildings?

3. How much time do we
spend inside?

4. Over 93 percent

6. Construction Industry
7,5 trillion dollars – global output 2009
100 mil. employees

7. WHAT ARE GREEN BUILDINGS?
•Philosophy: more effective use of resources (energy, water,
timber, building materials...)
•Goal: reducing negative impact on human health and the
environment during the whole life-cycle of the building
•Through: ideal position and orientation, creative design and
construction, use of suitable materials, energy and water
savings, building management systems, building site and
project management, recycling of materials
Green buildings save
Environment & costs

8. MARKET SITUATION
Worldwide trend
Energy crisis  public pressure  growing social
responsibility  new corporate strategies
Slovakia
Gradual change of perception – brought mainly through
international corporations, but also local companies
What is needed
• owners/users, developers and investors' more positive
view on energy efficient buildings
• legislative changes and market flexibility

2011

9. 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 2020
20% less emissions of greenhouse gases compared to 1990 +
20% less energy + 20% energy from renewable sources
(predictions based on current situation – only about 10%)

10. 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)

11. 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

12. GBC Network Today

13. REASONS
Political pressure – e.g. EPBD II
Social responsibility - consideration towards
environment and people (tenants, inhabitants,
employees)
Economic sense – savings on utilities, higher real
estate value ...

14. SUSTAINABLE DEVELOPMENT
(Viable
Economies)
(Healthy
communities)
(Natural
Environment)

15. WHICH ONE IS GREEN?

16. OR THIS ONE... ?

17. COMPREHENSIVE VIEW
Energy savings
+
Tied to the economy
and
society
+
Aesthetic aspect

18. CERTIFICATES =
SUSTAINABLE BUILDING LABEL

19. Today, we are used to
- energy rating of appliances
- nutritional values on food
...so why not buildings?

20. Building Certificates Worldwide

21. 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 system
Harmonisation of sustainable building standards -
CEN/TC350

22. Rating tools consider mainly:
Use of resources:
 Primary energy
 Water use

23. Also:
Quality of Environment Inside
 Air quality
 Thermal comfort
Emissions/Waste
 CO2 emissions
 Construction waste
 Further waste produced
(change of purpose, demolition)

24. RATING TOOLS
What? Why? How?
 Raising the quality of construction...
 Objective assessment…
 Measurable/Comparable results...
A real rise in construction quality?
Reflecting time and market conditions
What was the starting point?

25. Not just a marketing?

27. Seeing is believing

28. “Architecture is sustainable
only if it is also beautiful!”
Prof. Robert Špaček, STU
