Which of the following Is a strategy for improving Indoor Environmental Quality during construction?

Covering duct work with plastic is a strategy for improving indoor environmental quality during construction. Covering duct work with plastic prevents dust, debris, and contaminants from entering the ducts and affecting the air quality of the building. This also reduces the need for cleaning and maintenance of the ducts after construction. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to “protect ducts during construction by sealing or covering with plastic” [1, p. 16]. References: LEED Green Associate Candidate Handbook, [Indoor Air Quality During Construction | U.S. Environmental Protection Agency]
