Energy Savings & Global Warming Prevented by Using Spray Foam Insulation on Residential Housing
Bayer Material Science LLC reports polyurethane insulating foams contribute to the realization of the zero energy, zero-emissions performance character of buildings

Pittsburgh, May 6, 2009 — Demonstrating its leadership in offering eco-friendly materials for the building industry, Bayer MaterialScience LLC participated in Engineering Sustainability 2009: Innovations that Span Boundaries. The conference, spearheaded by the University of Pittsburgh, took place recently at Pittsburgh’s David L. Lawrence Convention Center – the largest certified green convention center in the United States. 

The conference brought together engineers and scientists from academia, government and industry to share contributions that address the needs of developing green designs – including buildings, water management systems and transportation grids. Bayer MaterialScience scientists presented papers and posters that demonstrate the company’s breadth of materials and solutions for sustainable infrastructures and construction.

“We are committed to providing our customers with green building materials, so it makes sense to participate in a forum where experts can discuss how sustainable design can grow and flourish,” said Steven Reinstadtler, Coatings, Adhesives and Specialties market development manager for the Construction and Green Building Initiative, Bayer MaterialScience LLC. “As such, we are pleased to be a part of the Engineering Sustainability 2009 conference as presenters and as an industry supporter.”

Below are summaries of the eco-friendly expertise Bayer MaterialScience shared at the conference.

Papers and Presentations
Climate Protection Through Intelligent Construction
Authors: Mark W. Witman, Bayer MaterialScience LLC, Americas Region; Ruediger Utsch, Bayer MaterialScience, EMEA Region; Peter Neuwald, Bayer MaterialScience, EMEA Region; Manfred Rink, Bayer MaterialScience, EMEA Region

Bayer MaterialScience's global EcoCommercial Building initiative reflects the principle of bringing together the best materials, systems and technologies in order to construct a building to suit the climatic conditions at the site in question. This paper highlights Bayer's global Zero Energy EcoCommercial Building initiative. It describes the overall design concept and building performance modeling conducted for a first prototype concept building that may be slated for construction sometime in the future in the vicinity of New Delhi, India. The fundamental design of the concept building takes into account both the local climatic conditions and the site infrastructure. Low volatile organic compound (VOC) raw materials and systems utilized for coatings and adhesives; wavelength selective, polycarbonate multi-wall sheet; polymer-based LED lighting systems and polyurethane insulating foams contribute to the realization of the zero energy, zero-emissions performance character of this building.

Energy Savings & Global Warming Prevented by Using Spray Foam Insulation on Residential Housing
Authors: James Lambach, George Pavlovich, Bayer MaterialScience LLC

Insulation can significantly reduce energy use in buildings and prevent associated global warming. The screening study that serves as the topic for this presentation uses basic Life Cycle Assessment methods and energy consumption calculation methods to rapidly estimate the net energy savings and global warming reductions achieved when spray foam insulation is used in residential housing applications.

Findings from the screening study indicate that use of insulation for residential housing yields energy/global warming benefits that far outweigh energy consumed/global warming emissions generated from all other life cycle phases such as insulation manufacture, installation, transportation, etc.

Intelligent Concrete Coating Solutions for Sustainable Construction
Author: Steven Reinstadtler, Bayer MaterialScience LLC

As sustainable requirements become more prevalent in most construction projects, coatings technologies have evolved accordingly. This paper covers the latest developments in ultra-low or zero-VOC, two-component polyurethane coatings, and centers primarily on advances in two-component waterborne urethane coatings and polyaspartic coatings. Reinstadtler describes these technologies, their adaptability to current and future regulations, their use and application attributes, as well as several case studies where their proven performance makes these technologies ideal for sustainable construction.

Polyurea and Polyurethane Thick Film Coatings for Sustainable Protection of Wastewater Infrastructure
Authors: Steven Reinstadtler and Christopher Marshall, Bayer MaterialScience LLC

Concrete wastewater and process water infrastructure is under constant attack from acidic environments, harsh waste products and chemicals, and microbes. Additionally, cracks form in wastewater structures made of concrete due to settlement or freeze/thaw cycles. Left unchecked, these cracks allow the concrete to deteriorate further and can lead to the release of waste products into the environment and ground water supplies.

The use of a polyurea or polyurethane thick film coating acts as a barrier separating the concrete from the harmful waste environment that enhances the service life. These versatile coatings are extremely durable, yet possess elastomeric properties that allow the coating to bridge cracks in concrete infrastructure. This poster covers some of the basic chemistry behind these 100 percent solids coatings, structure/property relationships and typical application methods. Multiple examples are illustrated where these thick film coatings have been employed to protect wastewater and process water projects.

Novel Natural Oil Based Rigid Foams for Demanding Applications
Authors: Steven Schilling, Edward Ball, David Sounik, Bayer MaterialScience LLC

Current federal legislation has placed increased emphasis on reducing energy consumption and using renewable, natural resources to replace petroleum-based products. Using less energy and more renewable resources can provide obvious benefits to the environment and help mitigate climate change, as well as help decrease our dependence on oil.

Recent advances at Bayer MaterialScience have resulted in a new generation of natural oil polyols (NOPs) that can be tailored for improved processing and properties in polyisocyanurate foams. Bayer’s NOPs offer several advantages, such as low viscosity and high renewable content without sacrificing performance, and when used to formulate insulating foams, their high renewable content may allow these foams to qualify for the federal government procurement program for BioPreferredSM materials.

“At Bayer MaterialScience, our commitment to sustainability carries through to the products we manufacture and the markets we serve,” said Mark Witman, director, New Business, Industry Innovations, Bayer MaterialScience LLC. “For that reason, we are proud to be able to offer a broad portfolio of polycarbonates, polyurethanes, thermoplastic polyurethanes, coatings, adhesives and specialties that help the industry meet the growing demand for more sustainable buildings and infrastructure.”

Bayer MaterialScience LLC is one of the leading producers of polymers and high-performance plastics in North America and is part of the global Bayer MaterialScience business with nearly 15,100 employees at 30 sites around the world and 2008 sales of 9.7 billion euros. Business activities are focused on the manufacture of high-tech polymer materials and the development of innovative solutions for products used in many areas of daily life. The main segments served are the automotive, electrical and electronics, construction, medical, and sports and leisure industries.

Bayer Corporation, headquartered in Pittsburgh, is a subsidiary of Bayer AG, an international health care, nutrition and high-tech materials group based in Leverkusen, Germany.
