Question
Flush out process is performed to remove which of the following?
A. voc
B. Waste
C. Graywater
D. Blackwater
Answer
A. voc
Explanation
Flush out process is performed to remove volatile organic compounds (VOCs) from the indoor air after construction or renovation. VOCs are chemicals that can evaporate at room temperature and cause health problems, such as headaches, nausea, and irritation3. Flush out process involves supplying 100% outdoor air to the building for a certain period of time or until a certain amount of air changes are achieved.
The flush out process in LEED certification is performed to remove volatile organic compounds (VOCs) from a building. VOCs are chemicals that can off-gas from building materials, finishes, furnishings, and other products. They can cause adverse health effects and degrade indoor air quality.
The flush out process involves running the building’s HVAC system with 100% outside air prior to occupancy in order to ventilate the space, dilute VOC concentrations, and improve indoor air quality. LEED requires a building flush out as part of the Indoor Environmental Quality category.
Waste, graywater (wastewater from sinks, showers, washing machines, etc.), and blackwater (wastewater from toilets) are not the target of a building flush out. These are addressed through other measures such as construction waste management, wastewater reduction, and water efficiency practices.
Therefore, the correct answer is:
A. VOC
The flush out process is an important aspect of achieving good indoor air quality in LEED certified buildings by removing potentially harmful VOCs left over from the construction process. It helps provide a healthy indoor environment for occupants.
