Sustainable Construction Role Of Silicon Technology


Published on

Innovation, efficiency and sustainability have become such crucial needs for business and how silicon technology can help to meet those needs, particularly in the context of building design and protection. He will begin by discussing some of the factors influencing sustainability, defining sustainable building and explaining its benefits. Looking towards the future, he will reflect on why cities will increasingly depend on sustainable technologies and how silicon will contribute to the needs of urban areas. Eight key eco-design principles will be discussed. The presentation will end with a discussion of the next steps that are essential to ensure that sustainable building continues to progress.

Sustainable Construction Role Of Silicon Technology

  1. 1. Making Sustainable Construction a Reality: The Role of Silicon Technology Jean-Paul Hautekeer Global Marketing Manager Dow Corning Construction Business Leonardo Energy webinar, November 20, 2009
  2. 2. ―The Good Building‖ Beijing‘s National Centre for the Performing Arts Burj Dubai Westin Diplomat Hotel Guggenheim Museum AOL Time Warner Building 1
  3. 3. About Dow Corning Corporation • Owned equally by The Dow Chemical Company and Corning Incorporated • Global leader of the silicone industry since 1943 • Nearly $5.5 billion in sales (in 2008) • European Headquarters in Seneffe, Belgium • 10,000 employees worldwide • 20,000 customers worldwide • 7,000 products and services • More than 4,500 active patents • Silicone sealants for 50 years • Global construction support network 2
  4. 4. The Silicone Advantage • Virtually unaffected by weather -- rain, snow, humidity, ozone, or the sun's damaging ultraviolet rays -- for many years. • Silicone architectural coatings typically last twice as long as acrylic coatings, and silicone building sealants typically last three times as long as urethane sealants. • Structural silicone sealants installed in buildings around the world in the 1980s are still performing today. 3
  5. 5. Why are companies moving towards sustainability? • Protecting the environment while increasing economic competitiveness: – Dow Corning‟s research has found that 65 percent of business leaders believe that developing environmentally sustainable products is one of their top three priorities. • A broad societal shift towards sustainability: – Wider public support for sustainability and government initiatives supporting sustainability 4
  6. 6. What is Sustainable Design / Architecture? “Sustainable design integrates consideration of resource and energy efficiency, healthy buildings and materials, ecologically and socially sensitive land use and an aesthetic that inspires, affirms and enables.” – International Union of Architects‟ “Declaration of Interdependence for a Sustainable Future,” 1993 Social Bearable Equitable Sustainable Environment Viable Economic 5
  7. 7. The ―Four P‖-Strategy of Sustainable Design / Architecture Project (Design Quality) Prosperity / Profit (Economic Quality) People (Social Quality) Planet (Environmental Quality) 6
  8. 8. Benefits of sustainable building • Environmental benefits – Increase buildings‟ energy efficiency – Utilize renewable sources of energy – Reclaimed & recycled materials • Social benefits – Improvement of daily life through natural light, cleaner air, comfortable temperatures. – No leaks, condensation or mold, fewer allergies thanks to better insulation, sealing & materials – Technology and economic developments • Economic benefits – Reclaimed materials can be less expensive – Lower operating costs – Need fewer light fixtures thanks to natural light 7
  9. 9. Impact of Buildings on Resources & Environment – Why Should Architects & Engineers be Concerned?

  11. 11. Roles of Silicones as Enablers of Sustainable Architecture • Sustainable buildings requirements set by governments: – Energy efficiency and CO2 emission reduction targets – Environmentally friendly materials • Role of Silicones as Enabler in Sustainable Architecture: – Energy efficient and durable façade systems for commercial buildings – Energy efficient silicone-bonded window systems (for residential and commercial buildings) – Lower organic emissions (VOC) 10

Silicone-enabled sustainable building design Lower façade U-values than Automated ventilation control & mechanically fixed facades lighting control using natural light Air tightness Photovoltaic energy Rooftop planting Double skin façade Evergreen plant shield Double or triple active façade Lighting control using against sun and wind pane low-e glazing motion detection sensors Window Installation system Higher energy efficiency with bonded doors and windows 11 Dow Corning©
  13. 13. The ‗City of the future‘ Mega-cities are a key trend shaping our future How can current silicon/silicone technologies contribute to our future cities‟ needs? • Helping to produce solar and wind energy and efficient LED lights for buildings and urban spaces • Energy efficiency • Making housing more affordable through building innovation • Clean water • Enhanced safety 12
  14. 14. Technology for future cities: Passive House insulation Germany example Today Passiv Haus Envelope U-values ≤ 0.15 have significant implications for overall design and cost options as wall thicknesses exceed today‟s norms • Structural design • Building footprint size • Joint complexity • Useable floor area • Façade connections • Insulation / component weight • Natural light utilization • Net-to-gross area ratios • Aesthetics • Embedded energy costs 13
  15. 15. Technology for future cities: Silicon-based Insulation Performance and Vacuum Insulated Panels Comparative thickness to achieve U-value target multi-layer envelope film (Passiv Haus U-value ≤ 0.15, or R-value ≥ 38) 0.10 0.15 0.20 core bag Si-core VIP Aerogel Blanket ―Thin insulations‖ pressed silica core Phenolic Polyisocyanurate & Polyurethane Expanded Polystyrene (EPS) Mineral & Glass Wools 0 50 100 150 200 250 300 350 400 mm 14 2‖ 4‖ 6‖ 8‖ 10‖ 12‖ 14‖ 16‖
  16. 16. How can we build the city—or the world— of the future together? • Apply companies‟ technology and know-how towards practical changes • Create government initiatives that fund R&D, support demonstrations of technology and the creation of infrastructure • Develop close relationships between businesses and universities 15
