Study Notes
Ceiling Plan Definition
- A ceiling plan provides a detailed outline of the overhead interior surface of a room.
- It shows features like ceiling boards, partitions, ventilation, and lighting fixtures.
Ceiling Plan Purposes
- Prevents heat penetration from sunlight.
- Enhances the aesthetic appeal of a building.
- Acts as a thermal insulator.
- Allows for installation of lighting fixtures to highlight interior design.
Ceiling Plan Presentations
- Ordinary Presentation: Depicts elements such as ceiling board, partitions, ventilation, labels indicating ceiling material, and dimensions.
- Reflected Ceiling Plan: Shows ceiling features as if viewed through a mirror on the floor, providing a view of the ceiling from below.
- Reflected Ceiling Plan Features: Lighting fixtures, ventilation, smoke detectors, wood molding, and ceiling board.
Key Considerations in Ceiling Plan Design
- Ceiling Height:
- Habitable rooms with artificial ventilation must have a minimum height of 2.40 meters (floor to ceiling).
- For multi-story buildings, the first storey should have a minimum height of 2.70 meters, the second storey 2.40 meters, and subsequent storeys 2.10 meters of clear headroom.
- Mezzanine floors require a clear ceiling height of at least 1.80 meters above and below.
- Design Elements:
- Consider the distance between the floor and ceiling lines.
- Analyze the three-dimensional aspects of volume and space.
- Explore the use of unexpected materials and finishes.
- Evaluate light reflection and sound absorption.
Steps in Drafting Ceiling Plan
- Preparation: Begin with a floor plan and analyze its dimensions and shape.
