Iran Nezam Architecture Design Exam common mistakes
Iran Nezam Architecture Design Exam · Understand the traps and how to avoid them.
In the spatial composition section, candidates sketch a plan with rooms arranged in a straight line or grid without considering the hierarchy of public to private spaces, resulting in a layout that lacks a clear entry sequence and a defined central gathering space.
Under time pressure, candidates focus on fitting the required areas and forget to apply basic principles of spatial hierarchy and circulation, often because they treat the plan as a simple area calculation rather than a spatial narrative.
What to do instead
Before drawing, quickly outline the client's daily path from entry to private zones, mark the public, semi-public, and private zones, and place the main living space at the intersection of these paths. Practice with 15-minute concept diagrams that emphasize sequence and hierarchy.
In building technology and materials, candidates specify high-performance materials (e.g., aerated concrete, double-glazed units) without checking local availability, cost, or compatibility with the structural system, leading to constructability issues.
Candidates memorize material properties from textbooks but lack exposure to real-world procurement and construction constraints in Iran, and they often overlook the need to cross-check with local suppliers or standard details.
What to do instead
Build a personal checklist of common Iranian materials (e.g., LECA blocks, Yazd stone, steel joists) with their typical applications, costs, and limitations. For each design decision, ask: Is it available? Does it fit the structure? Can local labor install it? Review case studies of built projects in similar climates.
In structural design, candidates size beams and columns by rule of thumb (e.g., span/10 for beam depth) without verifying against actual loads or seismic requirements, and they often ignore the need for a lateral load-resisting system in high-seismic zones.
The exam often presents simplified structural layouts, and candidates rely on memorized proportions instead of performing basic load takedowns or considering Iran's seismic code (Standard 2800). Time pressure encourages shortcuts.
What to do instead
Practice quick load calculations for typical residential and office spans, and always sketch a lateral system (shear walls, bracing) on plans. Memorize key seismic detailing requirements from Standard 2800 and review past exam problems that test structural layout.
In building services, candidates show mechanical equipment (AHU, ducts) and electrical panels on plans without allocating sufficient space for maintenance access, clearance, or routing, resulting in clashes with structural elements or unusable rooms.
Candidates treat services as an afterthought, adding symbols at the end of the design without coordinating with architecture. They often underestimate the space required for ducts and pipes, especially in ceilings.
What to do instead
Integrate services early: reserve a service zone (e.g., 60–80 cm ceiling void) and a mechanical room with proper access. Use a simple coordination checklist: duct routing, pipe slopes, electrical risers, and maintenance clearances. Practice overlaying service plans on architectural plans in sample problems.
In building codes and professional practice, candidates apply general code requirements (e.g., egress width, fire separation) without checking the specific Iranian national building regulations (Mabhas 3, 4, etc.) or local municipal bylaws, leading to non-compliant designs.
Candidates rely on international codes or general knowledge, not realizing that Iranian codes have unique provisions (e.g., parking ratios, setback rules, earthquake regulations). They also neglect to consider the role of the supervising engineer.
What to do instead
Create a one-page summary of key numbers from Mabhas 3 (fire), 4 (egress), and 21 (postal). For each design, explicitly state the code clause you are satisfying. Practice with exam questions that test code application in plan review scenarios.
In urban design and site planning, candidates design a site without analyzing solar orientation, prevailing winds, or topography, placing buildings and open spaces in ways that create uncomfortable microclimates or ignore natural drainage.
Candidates focus on building layout and aesthetics but forget the site context, often because they are not accustomed to using climate data or topographic maps in schematic design.
What to do instead
Always start with a site analysis diagram: sun path, wind rose, slopes, and views. Use simple rules (e.g., living spaces facing south, service areas north, windbreaks on windward side). Practice with typical Iranian climates (hot-dry, cold, humid Caspian).
In the history of Iranian and Islamic architecture, candidates misattribute key features (e.g., the four-iwan plan, muqarnas, or windcatchers) to the wrong period or dynasty, or they confuse terms like chartaq and hasht-behesht.
The history syllabus is broad, and candidates memorize isolated facts without a timeline or geographic context. They often rely on superficial visual memory rather than understanding the evolution of forms.
What to do instead
Build a timeline linking dynasties (Achaemenid, Sassanid, Seljuk, Safavid, Qajar) with architectural innovations and examples. Use flashcards with images and key terms, and practice identifying plans and sections from major monuments like the Jameh Mosque of Isfahan or the Fin Garden.
In world architecture history and theory, candidates apply contemporary Western theories (e.g., phenomenology, deconstructivism) to non-Western contexts without acknowledging cultural specificity, or they confuse major theorists' positions.
Candidates may have studied theory from a Eurocentric perspective and lack exposure to non-Western architectural discourse, leading to superficial comparisons. They also tend to memorize names without understanding core ideas.
What to do instead
For each theorist (e.g., Vitruvius, Ruskin, Le Corbusier, Venturi), write a one-sentence summary of their main argument and a built example. When comparing, explicitly note cultural and historical context. Practice essay questions that ask for critical application.
In architectural drawing and digital tools, candidates produce CAD or hand drawings with inconsistent line weights, missing dimensions, or incorrect scale, making the drawing unreadable or misleading for construction.
Candidates focus on speed and quantity of drawings rather than clarity and standards. They may not have practiced enough with drafting conventions or software settings under exam conditions.
What to do instead
Adopt a standard layer and line-weight system (e.g., cut lines thick, projection lines thin). Before submitting, check scale, dimensions, and north arrow. Practice timed drawing exercises with a checklist: title, scale, dimensions, annotations, and legend.
In climatology and sustainable design, candidates propose passive strategies (e.g., thermal mass, natural ventilation) without quantifying their effectiveness or considering the specific climate zone, resulting in designs that may overheat or underperform.
Candidates learn sustainable design principles abstractly and fail to apply climate data (e.g., Givoni chart, Mahoney tables) to make informed decisions. They also may ignore local materials and construction practices.
What to do instead
For each climate zone in Iran, memorize 2–3 effective passive strategies and their limitations. Practice using simple climate analysis tools and always justify a strategy with a calculation or reference to local precedents (e.g., windcatchers in Yazd, shovadan in Bushehr).
