A robust method in environmental load assessment of buildings is urgently required to reduce the environmental burden of the construction industry. While the industry utilizes the life cycle assessment (LCA) method to assess environmental impacts of detailed designs, the implementation of changes at that late stage of development is often expensive and undesirable. On the other hand, during the early design stages, the LCA method is severely limited by the lack of information available, e.g., uncertainty about final materials to be used. This research study investigates how building information modeling (BIM) can facilitate LCA analysis at an early design stage.

A literature review is conducted to establish a framework for BIM and LCA integration, which creates the foundation for the development of a new BIM-based LCA tool. The tool is empirically evaluated on a large case study of a residential building in Denmark.

Case study results show that the new tool facilitates decision-making in an integrated design process, providing reliable LCA results on an early stage model, while avoiding intermediate manual input by the end user in contrast to other commercial LCA tools.

A first prototype of a BIM-based tool is demonstrated, which allows professionals, small architectural companies, students and researchers to calculate the environmental loads of the building in the early design stage in an automated, transparent and time-saving manner.

Shortcomings in the BRS MENTOR mainframe interface and the desirability of using the workstation capabilities of the PC were factors in the decision to develop and implement a microcomputer‐based interface to the BRS software and associated databases. The Interface Design Subcommittee's charge was to design and implement the interface components for the Library Information Workstation, a microcomputer public terminal that provides access to local and remote online catalogs, periodical index databases, campus information resources, and information files stored on the microcomputer. This article focuses on the design of the interface to the BRS/SEARCH software and ancillary periodical index databases—initially Current Contents, six Wilson databases, and ERIC.

The following classified, annotated list of titles is intended to provide reference librarians with a current checklist of new reference books, and is designed to supplement the RSR review column, “Recent Reference Books,” by Frances Neel Cheney. “Reference Books in Print” includes all additional books received prior to the inclusion deadline established for this issue. Appearance in this column does not preclude a later review in RSR. Publishers are urged to send a copy of all new reference books directly to RSR as soon as published, for immediate listing in “Reference Books in Print.” Reference books with imprints older than two years will not be included (with the exception of current reprints or older books newly acquired for distribution by another publisher). The column shall also occasionally include library science or other library related publications of other than a reference character.

A useful way to pinpoint information in OCLC FirstSearch is through a wordlist bound‐phrase search. A bound‐phrase search looks for the full title, author, and so forth. exactly as you type it. A wordlist search will tell you how many hits to expect before you are charged for a search. You can also browse through the wordlist for additional related terms that may be of interest.
