PPD Has the Most Content of Any ARE Division - You Need a Strategy, Not Just Time
The ARE Project Planning and Design (PPD) division has the broadest content scope of any of the six divisions. It covers structural systems (loads, material systems, lateral systems), environmental systems (HVAC, plumbing, electrical, lighting), building envelope (thermal performance, moisture control, glazing, roofing), sustainable design (passive strategies, energy modeling, LEED, ASHRAE), and building materials (concrete, steel, wood, masonry - their properties and specification). A candidate who approaches PPD by trying to read through all reference materials comprehensively will spend months learning without a clear sense of how the knowledge fits together or what the exam actually tests. A candidate who uses a strategic, content-prioritized approach will pass PPD efficiently. The following is the strategic study approach for the PPD division specifically.
Priority Areas
Based on the ARE 5.0 PPD Exam Guide's content weighting and candidates' reported experience, the highest-priority content areas are: (1) Environmental systems - HVAC system types, energy performance, ASHRAE 90.1 requirements, and ventilation standards. These appear frequently and span multiple types of questions. (2) Building envelope - assembly types, thermal performance (U-values, R-values), moisture control (air barriers, vapor retarders), and the failure modes of each system. (3) Structural systems - structural load types, lateral systems (shear walls, braced frames, moment frames), and how structural system selection affects architectural planning. (4) Sustainable design - passive design strategies (solar orientation, thermal mass, daylighting, natural ventilation), LEED fundamentals, energy modeling concepts. These four areas together represent the core of PPD content; a candidate who has mastered these four areas is well-positioned to pass.
Study Approach
For PPD, the study sequence that works best: start with a PPD practice exam to assess your baseline across all content areas; identify your 2-3 weakest content areas (where you get the most questions wrong); study those areas first and most intensively before rotating to content areas where you are stronger. For PPD specifically, studying by "system" (all thermal envelope content together, all HVAC together) is more effective than studying by reference source, because the exam tests integrated knowledge of how systems relate, not isolated fact recall.
Key Resources for PPD
The most important references for PPD preparation: ASHRAE 90.1 (energy code); ASHRAE 62.1 (ventilation); ASCE 7 (structural loads); the IBC (fire ratings, egress, construction types); and a mechanical systems reference (Mechanical and Electrical Equipment for Buildings by Grondzik and Kwok is widely used). These are the sources the ARE exam content is drawn from - studying the content organized around these references gives you the source-level understanding the exam tests.
Key Points
- PPD: broadest content scope; requires strategic prioritization, not comprehensive coverage of everything equally.
- Priority areas: environmental systems, building envelope, structural systems, sustainable design.
- Study approach: baseline assessment → identify weak areas → address weak areas first → rotate systematically.
- Study by system (all HVAC together) rather than by reference source for integrated understanding.
- Key references: ASHRAE 90.1, 62.1; ASCE 7; IBC; Grondzik/Kwok mechanical reference.
AREprep's PPD content is organized by system - structural, mechanical, envelope, sustainable, and materials - and aligned to the ARE 5.0 PPD Exam Guide content areas, giving PPD candidates a structured, prioritized study path through the division's broad content. AREprep's PPD flashcard deck and practice questions are the most efficient way to build the integrated, cross-system knowledge the PPD exam tests - which is why PPD candidates who use AREprep consistently report that the exam felt manageable rather than overwhelming.
Study PPD on AREprep
AREprep's PPD flashcards and practice exams are built around the actual NCARB exam guide - so every study session targets what the exam tests.
