Standards & Compliance Briefing: Steel CO2 Emissions, Recycled Concrete, Sediment Retention

The International Standards Organization (ISO) has published ISO 14404, a standard defining a method for calculating carbon emissions intensity from iron and steel production. The standard has two parts, addressing plants with blast furnaces and electric arc furnaces. The World Steel Association welcomed the standard, which it said is based on the CO2 data collection methodology that the industry has used for the past five years.

The American National Standards Institute (ANSI) Energy Efficiency Standardization Coordination Collaborative (EESCC) is calling for input on current or forthcoming standards, codes, guidelines, and conformance programs related to energy efficiency standardization in the built environment, as well as perceived gaps in energy efficiency standardization. Separate working groups will address five areas: building energy/water assessment and performance standards; systems integration and communications; building energy modeling, rating and labeling; evaluation, measurement and verification; and workforce credentialing. The EESCC encourages stakeholders to provide information by April 1 at

A proposed new ASTM International standard, ASTM WK39876, covers process, verification and record keeping procedures for recycling returned fresh concrete. Subcommittee C09.40 on Ready-Mixed Concrete is developing the standard, which ASTM says will ensure that returned fresh concrete mixed with new concrete has known and verifiable characteristics, and will also help manufacturers reduce waste disposal.

ASTM is also developing ASTM WK39691, a standard to measure basic physical properties of sediment retention fiber rolls, which are used to inhibit migration of sediment that has been displaced and carried by flowing water. Once it has been approved, manufacturers will use the standard to perform and document quality control, ASTM says.

Friendly Earth, a non-profit recycler in Washington state, has been certified to the e-Stewards standard. It is one of only three e-Stewards recyclers in the state, according to the Basel Action Network.

Products certified by SCS Global Services will appear on the web-based product data and documentation platform run by GreenWizard, under an alliance between the two companies. GreenWizard’s platform is designed to help building professionals find and manage product information for LEED and other green commercial construction. SCS’s certifications address recycled content, indoor air quality and wood content compliant with Forest Stewardship Council standards.   

The Santa Barbara Airport’s $63 million Airline Terminal Project has been certified LEED Gold. The 72,000-square-foot terminal, which opened in August 2011, reduces potable water consumption for irrigation by 50 percent and energy consumption by 42 percent via the baseline standard. More than 95 percent of construction waste was diverted from landfill, with existing roof tile, concrete and asphalt re-used for the terminal or other airport building projects, the airport said.

The Conrad New York hotel has secured LEED Gold for New Construction certification, one of only two hotels in New York City to meet LEED standards. Features include a green roof and roof garden, which grows vegetables for the hotel restaurant, as well as bike racks, low-flow plumbing, LED lights, low-VOC materials, locally sourced materials, Forest Stewardship Council-certified wood, and Energy Star kitchen equipment, the hotel says.
