DESCRIPTION

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.

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.

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

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

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

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)

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

Technology for future cities: Passive House insulation

Germany example

Envelope U-values ≤ 0.15 have significant implications for overall

design and cost options as wall thicknesses exceed today‟s norms

• Structural design

• Joint complexity

• Façade connections

• Natural light utilization

• Aesthetics

• Building footprint size

• Useable floor area

• Insulation / component weight

• Net-to-gross area ratios

• Embedded energy costs

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
