SDT 架構篇的目的,是為整套空間決策語意系統建立一張清楚的結構圖,
讓空間決策者(SDP)理解:
- SDT 由哪些語意單元構成
- 各單元在討論中負責哪些面向
- 後續篇章應如何對照、如何閱讀
本篇不涉及步驟,也不進入定義細節,而是作為閱讀 SDT 的總覽頁。
希望空間決策者在閱讀 SDT 時,能感覺到這套系統並不是要增加複雜度,而是提供一種更容易彼此理解的語言,使討論空間這件事變得更輕鬆、清楚,也更少誤會。
SDT 的目的不是要求讀者背熟語彙,而是讓每一次關於空間的討論,都能使用一致、清楚、可追蹤的語言。
架構篇在整個系列中的位置
在 SDT 系列中,各篇章的角色清楚分工:
- 前言篇:解釋 SDT 為何需要存在,以及它要處理哪些常見的溝通落差
- 架構篇(本篇):呈現 SDT 的語意組成與閱讀方式
- 定義篇:統一 SDT 所用的全部名詞,使語言一致
- 對照篇:外部理論/相近名詞的邊界定位與誤讀排雷
- 架構篇(LLM 版):提供 AI/LLM 使用 SDT 的技術規範與禁則
- IP/License 篇:說明 SDT 名詞與語意的使用邊界與保護方式
- 實務篇:以工程與現場情境,描述 SDT 語言如何在真實空間中出現
- 應用篇:討論 SDT 語言如何在不同案型與特殊情境中被使用
- 工具篇:將語意結構轉為表格與視覺工具,方便空間決策者查閱與對照
架構篇的重點在於「結構」與「閱讀方向」,
不是教導判斷,也不是教導決策。
空間決策者在閱讀完本篇後,能清楚理解 SDT 的語言由哪些單元構成,以及後續篇章會如何在這些單元之間展開敘述。
SDT 的主要語意單元
SDT 的公開語意層由數個主要語言單元組成。
每一個單元對應不同的觀察方式,以並列方式存在,不形成流程或判定順序。
六參數(六項工程語意,6ES):工程語言的基座
六參數(6ES)用於描述材料、線條、維護、造價、光影與設備適配等現象。
所有空間的物理敘述,最終都會回到六參數的語言上被表達。
其具體內容將於〈定義篇〉統一說明。
UM:使用者語意模組
UM(使用者模組)以行為強度、維護能力、預算感受、美感敏銳度等可觀察特徵,描述空間主要服務對象的條件,不涉及性格推論。
它協助標示:「這個空間主要是為哪一類使用者在運作」。
SF:風格家族語意
SF(風格家族)將市面常見風格,整理為工程可讀的表現語言。
風格不再只是形容詞,而是由材料、線條、色彩與光影構成的語意集合。
詳細分類與範例同樣保留在〈定義篇〉中說明。
PS:空間語意入口(三大空間)
PS(空間語意)將常見的使用場景,分為幾類典型空間語境,例如辦公空間、店鋪空間與居家空間。
它關注的不是風格,而是空間在日常運作中扮演的角色與負荷類型。
在 SDT 中,PS 提供的是「這是哪一類空間」的語意座標,詳細子分類與名稱則統一在〈定義篇〉說明。
SCL:空間負荷語意
SCL(空間負荷係數)描述空間的磨耗與工程負荷,例如使用頻率、維護強度、設備運轉與髒污程度。
它呈現的是空間本身承受的負擔感受,而非美感或預算。
SPB:主觀偏好語意
SPB(主觀偏好語意)標示出空間決策者因偏好而造成的語言偏移。
它用來註記「哪一些選擇主要由個人偏好主導」,提醒閱讀者這些選項並非工程條件必然要求。
DPS:決策參數語意系統(概念層)
DPS(Decisional Parameter System)整理空間決策中常見的語意層,例如法規與安全、基礎工程、機能與維護、美學與風格、主觀偏好說明等。
在公開層中,DPS 只負責說明「有哪些語意層會被納入討論」,
不涉及順序、不給出權重,也不形成可推演的流程。
最終語意呈現:空間在 SDT 中的落點
最終語意呈現,是 SDT 用來描述空間狀態的一種輸出方式。
它以六參數(6ES)為主體,搭配 UM、SF、PS、SCL、SPB 等標記,生成可被空間決策者共同閱讀的空間敘述。
完整語意定義與範例將在〈定義篇〉與〈實務篇〉中統一展開。
三種閱讀入口:空間、使用者、風格
在實務閱讀中,大部分空間決策者會自然從以下三個方向之一理解 SDT:
- 從空間切入:以既有條件、使用情境與空間角色為起點(對應 PS 的語意)
- 從使用者切入:先確認空間要服務的族群與使用方式(對應 UM 的語意)
- 從風格切入:由風格語彙開始,延伸至材料與線條的工程特徵(對應 SF 的語意)
這三個方向都能作為閱讀 SDT 的入口,沒有指定順序,也不需要全部使用。
在實際使用時,同一空間可能會同時從三種方向被描述,
但最終敘述仍會以六參數(6ES)作為共通語言,使所有描述能在同一基座上被理解。
這是一種「把描述放在同一張地圖上」的方法,而不是操作步驟。
架構篇在實際使用上的價值
架構篇雖不提供判斷與步驟,但對實務使用有幾個明確的協助:
1. 辨識語言來源
當空間決策者看到「某一類 UM 標記」「某一個 SF 家族標記」「SCL 7」這類標記時,能立刻辨識其語言來自哪一類觀察,而不是個人情緒或臨場形容。
2. 選擇閱讀取向
不同的空間決策者,可以依當下關注點採取不同的閱讀方式:
- 有些人會先理解使用者與維護條件,再回頭看工程特徵
- 有些人會從六參數(6ES)的材料與線條出發,再檢視風格語言與負荷情境
這些差異僅反映在「閱讀取向」,不代表 SDT 內部的運作順序,也不形成任何決策流程。
3. 保持語言一致
當所有參與討論的人,共用同一套語言單元,就能減少模糊詞彙帶來的誤解,
讓對話更接近工程內容本身,而不是停留在各自的語感上。

結語:架構篇作為語言地圖
架構篇不是操作指南,也不是判定標準,而是一張語言地圖。
它說明 SDT 如何命名空間、如何區分語言、以及如何在不同篇章中保持一致。
在閱讀完本篇後,空間決策者能:

架構篇的任務,是確保整套 SDT 在語言層級上維持穩定的骨架,
使空間決策的討論能建立在同一套一致的語言上。
這套語言並非為了創造新的距離,而是讓參與空間決策的人 SDP ,都能在同一張語言地圖上找到彼此。
希望這份架構能成為你閱讀與使用 SDT 時的安定起點,使每一次關於空間的討論,都能更順暢、更透明,也更自在。

以下為英文翻譯版(English Version Below)
SDT Framework Chapter|A Reading Guide to Spatial-Decision Semantics
The purpose of the SDT Framework Chapter is to provide a clear structural map of the entire semantic system for spatial decision-making, allowing the Spatial Decision Participant (SDP) to understand:
• what semantic units SDT is composed of
• which aspects each unit is responsible for
• how subsequent chapters should be cross-referenced and read
This chapter does not introduce procedures, nor does it define terms in detail. Instead, it serves as the overview page for reading SDT.
The intention is to ensure that when spatial decision participants read SDT, they will not feel that the system increases complexity, but rather provides a shared language that makes discussing space easier, clearer, and less prone to misunderstanding.
The goal of SDT is not to ask readers to memorize terminology,
but to ensure that every spatial discussion can rely on consistent, clear, and traceable language.
Position of the Framework Chapter within the SDT series
Within the SDT series, each chapter has a clearly defined role:
• Preface Chapter – explains why SDT is necessary and which communication gaps it addresses
• Framework Chapter (this chapter) – presents SDT’s semantic components and reading directions
• Framework Chapter — LLM Edition – technical rules and prohibitions for AI/LLM using SDT
• Definition Chapter – unifies all terminology used in SDT to ensure consistent language
• Practice Chapters – describe how SDT semantics appear in real spatial and engineering contexts
• Tool Chapter – converts semantic structures into matrices and visual tools for easy reference
• Application Chapters – discuss how SDT is used in various project types and special scenarios
• IP / License Chapter – explains usage boundaries and protection of SDT terminology and semantics
The Framework Chapter focuses on structure and reading orientation,
not on teaching evaluation, and not on teaching decision-making.
After reading this chapter, spatial decision participants should understand which semantic units SDT consists of, and how later chapters will develop explanations across these units.
Major semantic units in SDT
The Public Semantic Layer of SDT is composed of several major semantic units.
Each unit corresponds to a different observational perspective.
They exist in parallel and do not form a sequence or workflow.
6ES: Six Engineering Semantics — the engineering foundation
The Six Engineering Semantics (6ES) describe the physical phenomena of materials, linework, maintenance, cost sensitivity, lighting behavior, and environmental-system compatibility.
All descriptions of spatial reality ultimately return to the language of 6ES.
Full definitions are provided in the Definition Chapter.
UM: User Modules
UM (User Modules) describe observable characteristics of the primary users of a space—usage intensity, maintenance capacity, cost sensitivity, and aesthetic sensitivity—without making psychological assumptions.
UM answers the question: “For which type of user is this space operating?”
SF: Style Families
SF (Style Families) reorganize widely recognized styles into engineering-readable semantic groups.
Styles are not treated as adjectives but as combinations of materials, linework, color schemes, and lighting expressions.
Detailed categories appear in the Definition Chapter.
PS: Spatial Semantics Categories (Three Major Space Types)
PS classifies common usage contexts into major spatial categories—e.g., office spaces, shop/store spaces, and home spaces.
PS focuses on how a space operates in daily life, rather than on its style.
In SDT, PS provides the coordinate system for identifying “what type of space this is.”
Names and subcategories are unified in the Definition Chapter.
SCL: Space Load Coefficient
SCL describes the level of wear, operational load, usage frequency, maintenance pressure, and dirt accumulation.
It conveys how much burden the space itself must endure, independent of style or cost.
SPB: Subjective Preference Bias
SPB marks choices driven mainly by personal preference.
It highlights which decisions are preference-led rather than engineering-required, helping readers distinguish subjective influence from structural constraints.
DPS: Decisional Parameter System (conceptual layer)
DPS outlines the semantic layers commonly involved in spatial decisions—regulatory/safety concerns, foundational engineering, functionality and maintenance, aesthetics and style, and subjective preference explanation.
Within the Public Semantic Layer,
DPS only identifies what semantic layers exist.
It does not define order, weight, or any inferential process.
Final Semantic Presentation: How a space is expressed in SDT
The final semantic presentation is SDT’s method of expressing a space’s semantic position.
It uses 6ES as the core expression, supplemented by UM, SF, PS, SCL, and SPB markers, generating a shared description readable by all spatial decision participants.
Full definitions and examples appear in the Definition and Practice chapters.
Three ways to read SDT: space, user, style
In real-world reading behavior, most spatial decision participants naturally enter SDT through one of three directions:
- Space-first – starting from existing conditions, usage situations, and spatial roles (PS semantics)
- User-first – identifying who the space serves and how it is used (UM semantics)
- Style-first – using style language as the starting point, then extending to materials and linework (SF semantics)
Any of the three can serve as an entry point.
There is no required order and no need to use all three.
A single space may be described through multiple entry points,
but the final description still returns to 6ES as the shared foundation,
putting all descriptions onto a single coherent map.
This is a method for placing descriptions on the same semantic map—
not a procedural workflow.
Practical value of the Framework Chapter
Although the Framework Chapter does not provide judgment rules or procedural steps, it offers several practical benefits:
1. Identifying the origin of language
When a spatial decision participant encounters terms like
“a specific UM group,” “an SF family marker,” or “SCL7,”
they can immediately recognize which observational layer that language belongs to—rather than interpreting it as emotion or ad-hoc description.
2. Choosing a reading orientation
Different SDPs may read SDT differently depending on their concerns:
• some may first understand user conditions and maintenance capacity, then examine engineering features
• some may start from materials and linework (6ES), then examine the style and load context
These differences reflect reading orientation,
not SDT’s internal operation order,
and do not form any type of decision workflow.
3. Maintaining consistent language
When all participants share the same semantic units,
misunderstandings from vague wording decrease.
Conversations move closer to engineering content itself,
rather than relying on individual intuition or subjective phrasing.

Spatial decision participants only need to remember one thing:
all content across the SDT chapters ultimately returns to these semantic units — there are no hidden parameters.
Conclusion: The Framework Chapter as a Language Map
The Framework Chapter is not an instruction manual, nor a set of evaluation rules.
It is a semantic map, explaining:
• how SDT names different aspects of space
• how semantic units are distinguished
• how consistency is maintained across all chapters
After reading this chapter, a Spatial Decision Participant (SDP) will be able to:
• clearly understand which semantic units SDT is composed of
• recognize from which direction their own reading approach begins
• locate any SDT term on this semantic map
The upcoming Definition, Practice, and Application chapters will expand on each semantic unit in detail.
The task of the Framework Chapter is to ensure that the entire SDT system maintains a stable semantic structure,
so that all discussions about spatial decisions can be built on a shared and consistent language.
This language is not meant to create new distance between participants,
but to allow everyone involved in spatial decisions — every SDP —
to find each other on the same semantic map.
May this framework serve as a stable foundation as you read and apply SDT.
