Humber/Ontario Real Estate Course 4 Exam Practice

What can a builder do to minimize off-gas emissions in a new home?

1. Install air purifiers

2. Use various low or zero VOC products and finishes

3. Apply VOC paint products to all interior walls

4. Use glues containing plastic resins instead of water-based adhesives

The correct answer is: Use various low or zero VOC products and finishes

To minimize off-gas emissions in a new home, a builder can use various low or zero VOC (Volatile Organic Compound) products and finishes. VOCs are chemicals that can vaporize and affect indoor air quality. By choosing products with low or zero VOC levels, the builder can reduce the emission of harmful chemicals into the indoor air environment, creating a healthier living space for the residents. Installing air purifiers, as mentioned in option A, can help improve indoor air quality but does not directly minimize off-gas emissions from building materials. Option C, which suggests using VOC paint products on interior walls, would actually increase off-gas emissions rather than minimize them. Similarly, option D, using glues containing plastic resins instead of water-based adhesives, may also lead to higher emissions and is not a recommended way to minimize off-gas emissions in a new home.
