Study Notes

### Ceiling Plan Importance

A ceiling plan serves as an outline of a building's ceiling and is used to display an overhead view of the room's interior surface.
Ceiling plans play a crucial role in building design and construction.
- Prevents sun heat from entering the building
- Enhances aesthetic appeal through well-designed features
- Acts as a thermal insulator
- Provides space for lighting fixtures, improving interior design
- They are important for architectural drafting as they help in visualizing the room's overall design and ensuring that the lighting and other ceiling elements are properly planned and installed

Ceiling Plan Types

Ordinary Presentation of Ceiling Plan - This presentation shows detailed elements like ceiling boards, partitions, ventilation, and labels indicating the type of materials used.
Reflected Ceiling Plan - A drawing that portrays the ceiling as if it were reflected onto a mirror placed on the floor. This provides a top-down view of the ceiling and its features.
- Interior designers often utilize reflected ceiling plans when designing spaces.
- This presentation showcases critical features such as:
  - Lighting Fixtures
  - Ventilation Systems
  - Smoke Detectors
  - Wood Molding
  - Ceiling Boards

Considerations for Ceiling Plan Design

The ideal distance between the floor and ceiling line should be thoroughly examined.
Three-Dimensional aspects of volumes and spaces should be factored in during design.
Employing unique materials or finishes can add a distinct touch to the ceiling's aesthetics.
The effect of light reflection and sound absorption must be considered to ensure a comfortable and functional space.

National Building Code Requirements

The National Building Code of the Philippines (PD 1096) mandates minimum ceiling heights for habitable rooms.
- Rooms equipped with artificial ventilation require a ceiling height of at least 2.40 meters.
- In multi-storey buildings, the first floor must have a minimum ceiling height of 2.70 meters.
- Subsequent floors should have a minimum ceiling height of 2.40 meters, with a headroom clearance of no less than 2.10 meters above the finished floor.
- Mezzanine floors require a clear ceiling height of at least 1.80 meters above and below.

Drafting a Ceiling Plan

Steps:
- Secure a ready-made floor plan and analyze its size and shape.
- Carefully transfer essential dimensions from the floor plan to the ceiling plan, ensuring accuracy.
- Draw the outline of the ceiling based on the floor plan.
- Indicate the position of various ceiling features like lights, smoke detectors, vents, and other elements.
- Add labels and annotations to clearly describe the ceiling materials and types.
