Calculator performs life cycle assessment for slag cement concrete

IMAGE

The Slag Cement Association has programmed a calculator with which concrete producers can quantify and interpret cradle-to-gate life cycle assessments (LCA) reflecting the environmental impact of mixtures with and without slag cement. Calculations are based on the industry-average Environmental Product Declaration (EPD) for ready mixed concrete that incorporates industry-average EPDs for slag cement and portland cement in the United States. The calculator also allows users to evaluate how different concrete mixtures affect whole building impacts based on a typical case study project.

Construction life cycle assessment pioneer retools Pavement software

Sources: Athena Sustainable Materials Institute, Ottawa; CP staff

The developer of a life cycle assessment (LCA) tool informing ready mixed and manufactured-concrete interests’ product category rules (PCR) and environmental product declarations (EPD) has released Pavement LCA Version 2.1, succeeding the Impact Estimator for Highways software. Athena Institute envisioned the charter program for major freeway and arterial roadway assessment, but notes the tool can now gauge the environmental footprint of any roadway cross-section along its length and over its service life.

NRMCA caps first phase of industry-wide Environmental Product Declaration

A representative sampling of energy consumption trends from a coast-to-coast, cross section of producers contributes to the NRMCA LCI Data Collection Summary Statistics, boosting the credibility of an industry-wide EPD for transit or central mixed concrete.

The first of two phases in the National Ready Mixed Concrete Association’s development of a standard Environmental Product Declaration (EPD)—aimed at assisting ready mixed producers on projects where customers target certification under the new LEED v4 green building rating system—has produced a survey report and list of participating companies and plants.

SOFTWARE EXTRACTS MATERIALS’ LIFE CYCLE ASSESSMENT FROM LEADING BIM PROGRAM

Tally software provides life cycle assessment data on concrete and steel—yellow and green on the pie charts, respectively—and other materials and products early in the design stage. In response to new requirements in LEED v4, Challenge 2030 and other rating systems or project benchmarking efforts, green building practitioners are increasingly weighing LCA data in specifications.

Philadelphia architect KieranTimberlake has released a beta version of Tally, a software application allowing users to measure building materials’ and products’ environmental impact directly in Autodesk’s Revit—a key software program to support building information modeling.
