Ventilation System

The consequences of
unintentional ventilation are:
Wasted energy (and money) used in
mechanical heating or cooling

A general decrease in occupant comfort
and or safety
Purpose of ventilation system

o Understand the role of energy efficiency in ventilating
activities
o Plan for ventilation system distribution and coverage
o Keep occupant comfort, well-being, and activities in mind
o Understand climate and ventilation-related interactions
o Identify potential sources of indoor pollutants
o Be aware of air pollutants from the local environment
o Understand the role of building construction in air
tightness and building integrity
o Design ventilation strategies for different building types
o Understand the role of energy efficiency in ventilating
activities.
LAY OUT PLAN- L.A
Ventilation-Related Issues

Some important issues to think about when
designing a ventilation strategy
include the following:
• Local climate
• Local energy prices
•Building air tightness, interstitial spaces, and
vertical and horizontal connections
• Pressure balances between zones
•Ventilation system distribution and coverage
Air conditioning selection

 The floor area of the room
 The size and position of windows, and
 whether they have blinds or shades
 The number of room occupants (if any)
 The heat generated by equipment
 The heat generated by lighting

Fire protection

• post the fire safety plan on the inside of apartment front door.
• post the fire safety plan in a conspicuous space in the common
area.
• distribute a copy to each dwelling unit in the building.
• provide a copy to new tenants at the time of the lease.
• re-distribute the fire safety plan annually during fire
prevention week.
