The NCSU Libraries now provides NC State readers with Marshall & Swift Equipment Cost Index online.
NC State users will need to authenticate themselves with a Unity ID to get access to the 2nd Quarter 2013 Marshall & Swift Equipment Cost Index. This will be updated quarterly. February 2012 and older listings of the Marshall & Swift Equipment Cost Index can be found in the “Economic Indicators” page of the journal Chemical Engineering.
Marshall & Swift Equipment Cost Index was created to make comparisons between two former quarters or years. Index comparisons are developed by dividing the index for the date for which a cost is desired by the index for the date of the known cost and multiplying the resulting factor by the known cost. The Marshall & Swift Equipment Cost Indexesare based on a national average for 47 different industries. A cost index is made up of a market basket of equipment and indicates the general direction in which equipment costs are moving. They represent an estimate of the trends in installed equipment costs from 1914 to date.
An individual industry index represents a composite of the entire plant equipment and does not consider machinery or other major items individually. The cost of individual plants or pieces of equipment may deviate from the given index, but in a typical industry, the overall costs will follow the index. The indexes are national averages, and are computed quarterly. Costs representing industrial and manufacturing engineering, machinery, mechanical and electrical installation, office equipment, furniture, fixtures, hand tools, and other items are combined in the proportion to their average occurrence in each of the listed industries. These are additionally weighted by a factor representing the general business activity and status of the economy at the time of computation.

NCSU Libraries has purchased an educational license for the ecoinvent data
v2.2 – a database of Life Cycle Inventory data. It is accessible through the
ecoinvent data v2.2 is a database of life cycle inventory (LCI) data on
energy supply, resource extraction, material supply, chemicals,
metals, agriculture, waste management services, and transport
services. Data sets from 2003 through 2010 are currently available
through Ecoinvent. LCI data (raw data and results) of more than 4,000
processes, products and services including infrastructure (such as the
manufacturing of cars, erection of power plants, construction of
roads, etc.) are available.
The following are some of the life cycle impact assessment methods
available through ecoinvent data v2.2:
- Cumulative Energy Demand (CED),
- Cumulative Exergy Demand (CExD),
- Environmental Design of Industrial Products (EDIP 2003),
- Eco-indicator 99 (all three perspectives),
- Ecological Footprint,
- Environmental Damage Potential (EDP),
- Impact 2002+,
- TRACI, and others
