## What are the ventilation requirements for a given space?

The sum of the operable open areas must total at least 5 percent of the floor area of each space that is naturally ventilated. The openings must also be readily accessible to the occupants of the space at all times.

## Do storage rooms require ventilation?

Every inside storage room shall be provided with either a gravity or a mechanical exhaust ventilation system. Such system shall be designed to provide for a complete change of air within the room at least six times per hour.

Do Copy machines emit ozone?

During operation, photocopiers emit toner particles, toxic gases namely ozone, nitrogen dioxide, volatile organic compounds, semi-volatile organic compounds, radiation, particulate matter, paper particles, nano particles and extremely low-frequency electromagnetic fields [2-4].

Do mechanical rooms require ventilation?

All mechanical rooms must be mechanically ventilated to maintain room space conditions as indicated in ASHRAE 62, ASHRAE 15, and Table 5-1 of this chapter.

### Do electrical rooms require ventilation?

How many CFM does it take to ventilate a room?

For continuous indoor air quality ventilation, a heat or energy recovery ventilator (HRV or ERV) should provide 0.35 air changes per hour….Heat and energy recovery ventilators.

Total area of home (square feet) Continuous ventilation rate
1,000 square feet 50 CFM
2,000 square feet 100 CFM
3,000 square feet 150 CFM

#### How do you calculate air flow needed?

Start with the total volume of air (in cubic feet), divide by the exchange rate (how quickly you want to replace the air), and the result is the total CFM you need for your system.

#### What is the maximum allowed distance between ventilation openings?

Ventilation requirements Vents should be located within 750 mm of corners and then evenly spaced around the building at 1.8 m centres maximum. No part of the subfloor should be further than 7.5 m from a ventilation opening.
