Humber/Ontario Real Estate Course 3 Exam Practice

Which measure can a builder take to reduce off-gas emissions in a new home?

1. applying high-gloss paint finishes

2. installing finishes with plastic resins

3. installing HEPA filters

4. installing rain screens

5. using low or zero VOC products

6. ventilating with outside air

The correct answer is: using low or zero VOC products

To reduce off-gas emissions in a new home, using low or zero VOC (Volatile Organic Compound) products is the most effective measure. VOCs can be emitted from various sources like paints, finishes, adhesives, and cleaning products, leading to indoor air pollution and potential health concerns. By opting for products with low or zero VOC content, the builder can significantly decrease the amount of harmful chemicals released into the indoor environment, thus promoting better air quality and a healthier living space for the occupants. Options A, B, C, D, and F are not as directly related to reducing off-gas emissions compared to using low or zero VOC products. High-gloss paint finishes (option A) and finishes with plastic resins (option B) do not necessarily indicate low VOC content. HEPA filters (option C) are more focused on air filtration rather than controlling the source of off-gas emissions. Rain screens (option D) are designed to manage moisture intrusion rather than reduce VOC emissions. Ventilating with outside air (option F) can help improve indoor air quality but may not specifically address the issue of VOC emissions.
