Architectural Knowledge

Chapter 1: Architectural Knowledge

Hello to all you future architects! Welcome to the world of architecture. This "Architectural Knowledge" chapter is like the first key that will help you understand how a building or a house is conceived. It’s not just about aesthetics; it also includes functionality, thermal comfort, and the feelings of the people who inhabit those spaces.

If you feel like the content is overwhelming or hard to memorize, don't worry! I’ve summarized it to be short, simple, and focused on the key points that TPAT4 exams love to ask. Let's dive in!

If it feels difficult at first, don't worry... because architecture is all around us. Try looking at the room you're sitting in right now, and we'll learn together.

1. Elements & Principles of Design

Think of design like "cooking." Elements are the ingredients, while the Principles are the recipes.

Basic Elements You Need to Know:

• Point: The smallest element that indicates a position.
• Line: Created by connecting points. Each type of line evokes different feelings; for example, vertical lines feel stable and elegant, while horizontal lines feel calm and expansive.
• Shape & Form: Shape is 2D (circles, triangles), while Form is 3D (spheres, cones).
• Space: The "air" inside or around a building. If there were no space, we wouldn't be able to enter, right?
• Color & Texture: These affect mood and touch. For example, warm colors can create excitement, while wood textures provide a sense of warmth.

Principles of Composition (Must Memorize!):

1. Unity: The sense of harmony and oneness; everything looks like it belongs together, not scattered.

2. Balance: Divided into Symmetry (left and right are identical; feels formal/still) and Asymmetry (left and right are different but have equal visual weight; feels modern/dynamic).

3. Rhythm: The repetition of elements, such as a row of columns, creating a sense of continuity.

4. Emphasis: Making a specific part of an image or building stand out more than the rest.

5. Proportion: The appropriateness of size. For example, a house door must be large enough for a person to walk through, not small like a cat flap.

Key Exam Point:

Golden Ratio: The ratio of approximately \( 1 : 1.618 \), believed to be the most beautiful and perfect proportion in nature. It is often found in world-class architecture like the Parthenon.

Summary of this section: Design is the act of arranging "points, lines, and colors" using "balance and rhythm" to create "unity."

2. Tropical Architecture

Since Thailand is hot, exams love to ask about how buildings adapt to the climate.

Principles to Remember:

• Sun Path: In Thailand, the sun primarily tracks via the south (for 8-9 months a year). Therefore, rooms you want to keep cool (like bedrooms) should not be placed on the south or west sides.
• Wind Direction: Wind usually comes from the southwest (monsoon/rainy wind) and northeast (cool, dry wind).
• Heat Protection: Using long eaves or sunshades to prevent direct sunlight from hitting the walls.
• Ventilation: Creating window openings that allow for air intake and exhaust (Cross Ventilation) to help flush out heat.

Did you know?

The "stilt foundation" (Tai-thun) of traditional Thai houses isn't just for escaping floods; it also allows wind to pass through more effectively and prevents soil moisture from rising into the house.

Key Point: The west is the hottest side during the afternoon. Placing bathrooms or staircases here can act as a "thermal buffer" to protect living areas inside.

3. Introduction to Architecture & Materials

You need to be able to distinguish between basic materials and types of structures.

Common Structures:

• Post and Beam: The most fundamental structure found in typical houses.
• Bearing Wall: Uses the entire wall to support the load instead of columns.
• Truss: Usually made of triangular steel frames, used for factory roofs or stadiums that require very long spans.

Construction Materials:

• Reinforced Concrete (RC): Durable and cost-effective, but heavy.
• Steel: Fast to build and strong, but expensive and requires maintenance against rust and fire.
• Wood: Beautiful and warm, but difficult to maintain and increasingly expensive.

Common Mistake: Students often confuse "concrete" with "cement." Just remember: cement is the powder like flour, while concrete is the "dish" made by mixing flour (cement), rocks, sand, and water until it sets and hardens.

4. Human Scale

Architecture is built for humans, so the size of things must be based on our bodies.

Numbers worth remembering:

• Stair Riser Height: Approx. 15-18 cm (any higher and it becomes tiring to climb).
• Stair Tread Width: Approx. 25-30 cm (enough to fit the sole of a foot).
• Desk Height: Approx. 75 cm.
• Chair Seat Height: Approx. 45 cm.

Memorization Trick:

If a question asks about size and you can't remember, "use your own body as a ruler." Try spreading your arms or imagine where a desk sits relative to your body while sitting; it will help you guess an answer very close to the reality.

Summary of Architectural Knowledge:
1. Understand composition principles (balance, unity, rhythm).
2. Know how to adapt to climate (sun from the south, wind from the southwest).
3. Understand proportions related to humans (Human Scale).
4. Identify basic materials and structural types.

Keep it up! This chapter might seem like a lot to memorize, but if you start observing the buildings around you, you'll definitely understand and remember it better. See you in the next chapter!
