Transcription

1 External Thermal Insulation Composite Systems (ETICS) for Sustainable Buildings: Performance, Standardisation and Quality Dr. Helge Kramberger, RMI, Germany 02/2011 1

2 ETICS for Sustainable Buildings External Thermal Insulation Composite Systems (ETICS) for Sustainable Buildings The Concept of Sustainability ETICS: Basic principles and benefits Standardisation of ETICS Test Methods Summary and Discussion Dr. Helge Kramberger, RMI, Germany 02/2011 2

3 The Concept of Sustainability What is the meaning of sustainability? Sociocultural factors If you plan for a year, you should seed grain, If you plan for a decade, you should plant trees, If you plan for a lifetime, you should educate humans. Guan Zhong (ca. 650 AC) Ecology Economy Dr. Helge Kramberger, RMI, Germany 02/2011 3

4 The Concept of Sustainability Criteria for sustainable buildings Sustainable Building ecological aspects social and health aspects economical aspects Technical quality Dr. Helge Kramberger, RMI, Germany 02/2011 4

5 The Concept of Sustainability Companies listed in the Sustainable Dow Jones Index Global supersector leaders 2009 BMW DSM NV Panasonic Electric Works Co Ltd Unilever Roche Holding AG Total SA adidas AG Nokia Corp.

7 ETICS: Basic Principles Mounting (Adhesive Mortar) Insulating Board (EPS) Reinforcing Mesh Reinforcing Mortar Finish Coat Dr. Helge Kramberger, RMI, Germany 02/2011 7

8 ETICS: Basic Principles > 70 C Temperature 20 C Wall Adhesive Thermal insulation board Top coat Base coat with glass fibre mesh Dr. Helge Kramberger, RMI, Germany 02/2011 8

9 ETICS: Benefits ETICS: Energy saving insulation for new buildings and retrofitting ETICS are suitable for new buildings as well as for retrofitting Thermal properties of building envelope can be improved by a factor 10 or more Calculation for a concrete wall with 15 cm thickness plus 12 cm insulation, indoor air 20 C, outdoor air 40 C: Thermal conductivity: 4,25 W/m²K 0,31 W/m²K Indoor wall surface: 32 C 21 C Energy saving for 1000 m² facade (medium office building): ~ 2000 kwh/day Architectural freedom in facade design Dr. Helge Kramberger, RMI, Germany 02/2011 9

10 ETICS: Benefits Sofitel Hotel, Dubai Dr. Helge Kramberger, RMI, Germany 02/

11 ETICS for Sustainable Buildings External Thermal Insulation Composite Systems (ETICS) for Sustainable Buildings The Concept of Sustainability ETICS: Basic principles and benefits Standardisation of ETICS Test Methods Summary and Discussion Dr. Helge Kramberger, RMI, Germany 02/

12 Why standardisation? Dr. Helge Kramberger, RMI, Germany 02/

13 Standardisation of ETICS Construction Product Building Composition / Design Performance of product Performance of building Dr. Helge Kramberger, RMI, Germany 02/

14 Specifications / Standardisation Obstructive for technical progress Too complex, stage too late Composition / Design Performance of product Performance of building Dr. Helge Kramberger, RMI, Germany 02/

15 Standardisation of ETICS Specifications / Standardisation Minimum requirements Backstop for technical progress Dr. Helge Kramberger, RMI, Germany 02/

16 Standardisation of ETICS Criteria for products: Limit values / performance classes Limit values will only guarantee minimum requirements Performance classes will enhance competition Minimum requirements More competition more overall technical quality Different construction situations need different products performance classes Tendering companies want to define quality levels performance classes Technical progress changes products performance classes Transparency for customers performance classes Backstop for technical progress Dr. Helge Kramberger, RMI, Germany 02/

17 Standardisation of ETICS Minimum requirement: four wheels, engine, brake Performance classes: A-Class to S-Class Dr. Helge Kramberger, RMI, Germany 02/

18 European approach for effective control of the construction sector Control by the market as barrier for non compliant products Mandatory labelling of product + central database of technical approvals possibility for simple check of compliance Only compliant products are allowed at construction site General terms and conditions: If non compliant products are used, the contractor will not be payed by the client! Competitors are trying to reveal non-compliant products Dr. Helge Kramberger, RMI, Germany 02/

19 European approach for effective control of the construction sector Additional possibilities for governmental control: Tiered approval systems AOC + FPC + monitoring by certified body AOC + Factory production control (FPC) Attestation of conformity (AOC) Potential danger Self declaration by manufacturer Dr. Helge Kramberger, RMI, Germany 02/

27 ETICS for Sustainable Buildings Summary Sustainability: More than green Also sustainability is based on technical quality ETICS as tool for retrofitting and energy saving buildings Standards and specifications are the key to higher quality RMI can provide know-how about testing and standardisation Dr. Helge Kramberger, RMI, Germany 02/
