5、with a researched, practical publication to assist in maintaining acceptable indoor air qualityduring building renovation, SMACNAs Building Services Committee developed the first edition of the IAQ Guide-lines for Occupied Buildings Under Construction. This manual has its roots in a workshop that to
6、ok place during theIAQ 1993 Conference that was cosponsored by SMACNA and other professional organizations. As the conferenceprogressed it became clear that, other than the combined experiences of the presenters and other specialized profes-sionals in attendance, there was little published technical
7、 guidance that dealt with the potential health hazards andannoyances related to carrying on construction activity in occupied buildings.This second edition of the IAQ Guideline has been updated and was passed through an additional review process usinga canvass review that meets SMACNAs American Nati
8、onal Standards Institute (ANSI) accredited procedures. TheANSI process assures that interested and affected parties have an opportunity to review, comment, and approve publi-cations as an ANSI standard document via a consensus process.The IAQ Guideline is intended to be an authoritative source for p
9、roviding project management guidance in maintain-ing satisfactory indoor air quality (IAQ) of occupied buildings undergoing renovation or construction. The Guidelinecovers how to manage the source of air pollutants, control measures, quality control and documentation, communica-tion with occupants.
10、It includes example projects, tables, references, resources, and checklists. The previous editionof the IAQ Guideline is referenced by the U.S. Green Building Councils LEED Green Building Rating System forExisting Buildings and New Construction. SMACNA recommends the guide to architects, engineers,
11、constructionmanagers, facility managers and building owners who will be involved in construction activities inside occupied build-ings. Additionally, the principles presented here are also applicable to IAQ problems encountered in occupied areasof buildings during the final phases of new constructio
