IE Q Credit 3.1: Construction Indoor Air Quality Management Plan—During
Construction
1 Point

Intent
To reduce indoor air quality (IAQ) problems resulting from construction or renovation and promote the comfort and well-being of construction workers and building occupants.

Requirements
Develop and implement an IAQ management plan for the construction and preoccupancy phases of the building as follows:
-- During construction, meet or exceed the recommended control measures of the Sheet Metal and Air
Conditioning National Contractors Association (SMACNA) IAQ Guidelines For Occupied Buildings Under
Construction, 2nd Edition 2007, ANSI/SMACNA 008-2008 (Chapter 3).
-- Protect stored on-site and installed absorptive materials from moisture damage.
-- If permanently installed air handlers are used during construction, filtration media with a minimum efficiency
reporting value (MERV) of 8 must be used at each return air grille, as determined by ASHRAE Standard 52.2- 1999 (with errata but without addenda1). Replace all filtration media immediately prior to occupancy.

Potential Technologies & Strategies
Adopt an IAQ management plan to protect the heating, ventilating and air conditioning (HVAC) system during
construction, control pollutant sources and interrupt contamination pathways. Sequence the installation of
materials to avoid contamination of absorptive materials, such as insulation, carpeting, ceiling tile and gypsum
wallboard. Coordinate with IEQ Credit 3.2: Construction IAQ Management Plan — Before Occupancy and IEQ
Credit 5: Indoor Chemical & Pollutant Source Control to determine the appropriate specifications and schedules for
filtration media.
If possible, avoid using permanently installed air handlers for temporary heating/cooling during construction.
Consult the LEED Reference Guide for Green Building Design and Construction, 2009 Edition for more detailed
information on how to ensure the well-being of construction workers and building occupants if permanently
installed air handlers must be used during construction.

IEQ C3.1: 施工室内空气质量管理—施工中
1分

目的
减少由于施工或改造造成的室内空气质量问题，为施工人员和建筑用户提供健康、舒适的环境。

要求
根据以下要求，制定施工和入驻前阶段的室内空气质量管理方案：
-- 施工中，达到或超过美国空调承包商协会(SMACNA)在“在用建筑施工中室内空气质量指南”
中所建议的控制措施，2007年第2版，ANSI/SMACNA 008-2008（第3章）。
-- 对现场存放的、安装的可吸潮性材料进行保护，防止潮气破坏。
-- 如永久安装的空气处理装置在施工要使用，则每个回风过滤罩使用的过滤介质的最低效率
报告值(MERV)必须达到8，符合ASHRAE 52.2-1999之规定。交工前必须全部更换。

技术措施和策略
施工中实施一个室内空气质量管理方案，来保护暖通空调系统，控制污染源、阻断污染路径。
安排安装程序防止吸收性材料的污染，如保温材料、地毯、吊顶板和石膏墙板。该项目应与IEQ
C3.2“施工室内空气质量管理—入驻前”和IEQ C5“室内化学品和污染源控制”项目配合，选
用适合的过滤介质规格和顺序。
如可能，施工中避免使用永久安装的空气处理装置，如必须使用，请参考LEED参考手册—2009
中详细信息，以确保施工人员和用户的健康。
