EQ CREDIT
Low-Emitting Materials (Up to 3 Points)
- Goal: Reduce harmful chemicals (VOCs) inside buildings
- Focus: Materials used during construction
👉 Memory shortcut:
“Choose materials that don’t pollute indoor air”
🔹 2. WHY THIS MATTERS
- VOCs → cause:
- Asthma
- Irritation
- Long-term health issues
- Materials = major source of indoor pollution
🔹 3. KEY CONCEPTS (SUPER IMPORTANT)
🧪 Emissions vs Content
Type | What it Means | Easy Way to Remember |
Emissions | What comes OUT of product | “What you breathe” |
Content | What’s INSIDE product | “What it’s made of” |
👉 Exam Tip:
- Both are required (especially for wet-applied products)
🔹 4. CREDIT STRUCTURE
📊 Two Options
Option | Approach | Complexity |
Option 1 | Product Category Thresholds | Easier |
Option 2 | Budget Calculation | Flexible but complex |
🔹 5. OPTION 1 – PRODUCT CATEGORY METHOD
🎯 Concept
Meet requirements across product categories
📊 Product Categories
Category | Threshold | Key Requirement |
Interior paints & coatings | ≥ 90% (emissions) + 100% VOC content | Must meet emissions + VOC limits (wet-applied rule) |
Interior adhesives & sealants | ≥ 90% (emissions) + 100% VOC content | Same wet-applied rule applies |
Flooring | 100% compliant | Must meet emissions standards |
Composite wood | 100% compliant (if not covered elsewhere) | Must meet composite wood evaluation |
Ceilings, walls, insulation | 100% compliant | General emissions evaluation |
Furniture | ≥ 90% by cost | Furniture emissions evaluation |
Exterior applied products (Healthcare/Schools only) | ≥ 90% by volume | Applies only to specific project types |
💧 Wet-Applied Products (VERY IMPORTANT)
👉 Includes:
- Paints
- Coatings
- Adhesives
- Sealants
Requirements:
Category Type | Threshold Logic |
Wet-applied products (paints, adhesives) | 90% emissions + 100% VOC |
Most other categories | 100% compliance |
Furniture | 90% by cost |
Requirement | Threshold |
Emissions | ≥ 90% compliant |
VOC content | 100% compliant |
👉 Classic exam question
🔹 6. OPTION 2 – BUDGET METHOD
🎯 Concept
Allows trade-offs across assemblies
👉 If some products don’t comply → others compensate
📊 Assemblies Used
Assembly |
Flooring |
Ceilings |
Walls |
Insulation |
Furniture |
Exterior (schools/healthcare only) |
🧠 Key Rule (VERY IMPORTANT)
Scenario | What to Do |
All layers compliant | Count full area |
Some layers NOT compliant | Use weighted average |
👉 High-value exam concept
🔹 7. IMPLEMENTATION STRATEGIES
Strategy | Description |
Non-emitting materials | Stone, glass, metal, concrete |
Manufacturer declaration | Self-reported compliance |
Third-party certification | BEST approach (CDPH, etc.) |
👉 Exam Tip:
Third-party certification = easiest + safest
🔹 8. IMPORTANT DEFINITIONS
Term | Meaning |
Interior | Inside waterproofing membrane |
Exterior | Outside weather barrier |
Furniture | Counts if installed at occupancy |
🔹 9. COMMON EXAM TRAPS 🚨
❗ Trap 1: Wet-Applied Products
- 90% emissions + 100% VOC content
- BOTH required
❗ Trap 2: Furniture
- Included if installed at occupancy
- Even if NOT specified by design team
❗ Trap 3: This is a Construction Credit
- Based on installed materials
- NOT just design intent
❗ Trap 4: Budget Method
- Uses assemblies
- Uses weighted averages
