WHICH IS THE MORE SUSTAINABLE BUILDING MATERIAL - WOOD OR STEEL?

WHICH IS THE MORE SUSTAINABLE BUILDING MATERIAL - WOOD OR STEEL?

Trimet Building Products

According to certain “studies,” wood claims a smaller environmental footprint than any other major building material. However, a closer look at the facts reveals some significant inconsistencies with that claim. MYTH: Studies demonstrate that wood is a more sustainable material than steel. REALITY: The most-cited study contained numerous incorrect assumptions about steel, and it omitted wood impacts. • A study cited often by the wood industry was published by the Consortium for Research on Renewable Industrial Materials (CORRIM) and is based on outdated information. For example, it made incorrect assumptions about the quantity of steel needed for its comparisons. • Wood is typically a single-use material. At the end of its life, a building’s wood frame is typically landfilled or incinerated. This returns any stored carbon dioxide back into the atmosphere as either carbon dioxide or methane, shifting greenhouse gas burdens to future generations. • In comparison, steel is the world’s most recycled material. Steel construction products have a recycling rate of more than 90 percent, meaning that at the end of a steel building’s life, more than 90 percent of its steel is recycled into another steel product, using significantly less energy than was necessary to create the original product. A material that can be recycled continually over centuries with no loss in quality and that lowers the burden on future generations is the very definition of sustainability! MYTH: Wood is more sustainable than steel because it is a renewable building resource. REALITY: Being renewable is not the same as being sustainable. • The wood industry claims that for every tree cut down, one or more new trees are planted. However, the claim does not take into account that it will take decades before those saplings mature. In the meantime, the forest is depleted of the oxygen, water storage and filtration, wildlife habitat, global cooling, and other benefits provided by the mature tree. 1 • Trees are often harvested by clear-cutting, leaving large gaps in the forestland that also impact the plants and animal species left behind. MYTH: Wood is more sustainable than steel because wood construction products store carbon. REALITY: Carbon storage for construction products is temporary, only shifting impacts to future generations. • Carbon is sequestered in the fiber of trees, but that does not mean that wood buildings become large reservoirs of carbon that is stored indefinitely. Upon harvesting, the unused root and leaf systems immediately return their CO to the atmosphere by decay. For wood products, the reality is that carbon storage is also temporary and it is released back into the atmosphere at the end of the wood building’s life either by the demolition and subsequent decay of the wood or by incineration. • Ann Ingerson of The Wilderness Society states: “As a result of wood waste and decomposition, the carbon stored long-term in harvested wood products may be a small proportion of that originally stored in the standing trees―across the United States, approximately 1 percent may remain in products in use and 13 percent in landfills at 100 years post-harvest.” 2 2 Photo courtesy of the American Institute of Steel Construction Photo courtesy of SCS Global Services MYTH: All wood construction products are certified as being sustainably harvested. REALITY: The majority of forests in the U.S. do not meet the wood industry’s own sustainable harvesting standards. • Eighty-one percent of forests in the United States are not certified, 11 percent are Sustainable Forestry Initiative (SFI®)-certified, and seven percent are Forest Stewardship Council (FSC®)-certified.3 The sustainable harvest certification provided by the Sustainable Forestry Initiative has often been challenged as to whether it reaches the required threshold of sustainable forestry. SFI was created in 1994 by the paper and timber industry. A report on SFI by ForestEthics concludes in part: - “SFI is funded, promoted and staffed by the very paper and timber industry interests it claims to evaluate.”4 - “Of SFI’s 543 audits, up to the time of the report’s issuance, there were no major noncompliance issues related to soil erosion, clear-cut procedures, watershed issues, or chemical usage.”5 - “SFI-certified logging practices are having a disastrous impact on North American forests.”6 • In actuality, only seven percent of the forestland in the United States reaches the threshold of being considered sustainably managed.

Pressure marking, also known as pressure mottling or imprinting, is an uneven or irregular gloss pattern on the face of a prepainted sheet steel. The photograph in Figure 1 shows what pressure marking looks like. The mottled appearance takes place when the gloss components in the prepainted top coat are compressed or flattened during the manufacturing and coiling process. The condition is more prevalent on dark colours and high gloss products. Pressure marking is also typically noted in the centre of the strip where the coiled product is under the most pressure

Explosion Venting for Steel Frame Buildings

CSSBI SSF 19-05: Explosion Venting for Steel Frame Buildings

Trimet Building Products

Executive Summary The aim of this fact sheet is to advocate an alternative solution for the Steel Industry in regards to restrictive code provisions for explosion venting that are now mandated by the Ontario Fire Code (OFC). Due to a September 2000 amendment of code provisions dealing with explosion venting in the OFC, explosion vent designs were required to be in conformance with NFPA 68, the National Fire Protection Association’s (NFPA) Guide for Venting of Deflagrations. NFPA 68 gives a prescriptive solution that has upper bound limits on size and mass of an explosion vent panel, which the Steel Industry finds are too small to be practical. The Canadian Steel Construction Council (CSCC) investigated this problem and identified an alternate design guideline from the Factory Mutual Insurance Company’s (FM) Property Loss Prevention Data Sheets, numbered 1-44 and entitled “Damage Limiting Construction”. FM’s 1-44 Data Sheets can be used to develop an alternate solution for explosion venting that exceed the size and mass limits of the NFPA 68 prescriptive solution, and can be submitted for approval under the Compliance Equivalency provisions in the OFC. With the introduction of an objective based National Building Code Canada (NBCC) in 2005 followed by Provincial code adoptions in 2006 it would be worthwhile to establish a precedent through the Compliance Equivalency provision in the OFC. Once a precedent setting case occurs, the “acceptable solution” or “compliance alternative” would go on record and aid in resolving subsequent proposals for Compliance Equivalency, and also support a future technical change in the OFC. The CSCC by way of this fact sheet would advocate this alternative solution for the Steel Industry when designing explosion vent panels in steel framed buildings.

In some of these end-uses it is arequirement that the wood be chemically treated (pressuretreated) to extend the service life.Designers and builders need to be aware that changes in theavailable wood perservatives may impact the durability ofany connected steel components or fasteners.Eective January 1, 2004 the Environmental ProtectionAgency (EPA) banned the use of Chromated CopperArsenate (CCA) as a preservative in treated lumber forresidential construction. This was done in an eort to reducethe use of chromate and arsenic thereby mitigating thepotential health and environmental problems. The woodpreservative industry has been switching to alternativewaterborne compounds including Sodium Borate (SBX),Alkaline Copper Quat (ACQ), Copper Azole (CBA-A and CA-B),and Ammoniacal Copper Zinc Arsenate (ACZA).Unfortunately, research has indicated that ACQ, CBA-A, CA-Band ACZA, the new generation copper-based products, aremore corrosive to galvanized steel than the former CCA.Since ACQ is becoming the predominant preservative in use,the discussions in this paper will refer to it exclusively.The purpose of this Fact Sheet is to convey the recommendations of the sheet steel industry for the application of steelproducts with ACQ pressure treated wood.

CSSBI SSF 20-14: Recycled Content of Steel Building Products

Trimet Building Products

The construction industry is a vital part of the growth and success of a country. It is responsible for building the physical infrastructure that provides transportation and facilities for citizens, businesses, industries and institutions. Construction has a major influence on the economic wealth, societal well¬being and sustainability of the built environment. The Canadian construction industry employs more than 1.2 million people. In 2010 it accounted for 6% of Canada’s gross domestic product (GDP), with a total value of 73.8 billion dollars. From 2000 to 2010, the GDP from construction increased 42.7% whereas GDP for all industries increased 20.2%.(1) Construction also has a profound impact on our natural environment. In North America, the built environment accounts for approximately one third of all the greenhouse gas (GHG) emissions, as well as energy, water and materials consumption. Given the increased awareness of “green” construction, there is growing interest in using steel because of the major recycled content and recyclability attributes it provides to architects, engineers and specifiers in the construction industry. The steel industry, through the Canadian Sheet Steel Building Institute is committed to providing steel solutions that promote the use of sustainable materials in construction applications. This fact sheet provides an overview of the two main methods used to produce steel, and describes the recycled content of the steels used to manufacture building products such as roofing, cladding, decking, structural and non-structural framing and the many other construction products used in the industry. Once iron ore is extracted and refined into steel, its life never ends. This makes steel an ideal material to deploy in sustainable strategies for the construction industry. Today’s steel is produced using two technologies both of which require “old” (recycled scrap) steel to make “new” steel. The combination of these technologies enables Canadian steel mills the flexibility to produce a variety of steel grades for a wide range of product applications
