The document discusses the design of ventilation, air conditioning, and other building systems. It outlines the purpose of ventilation systems to provide occupant comfort while saving energy. Important factors to consider for ventilation design include the local climate, building air tightness, and pressure balances. When selecting an air conditioning system, factors like room size, windows, occupants, and heat sources must be evaluated. Fire protection requirements include posting the fire safety plan at entrances and distributing copies to tenants.

- 1. Design of Air Conditioning & Ventilation Contents Ventilation System Air conditioning system Thermal comfort designing Fire protection Security system
- 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.
- 4. LAY OUT PLAN- L.A
- 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.
