2. 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

3. 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.

5. 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

6. 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

9. 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.
