EA Credit: Demand Response
๐น Introduction
Demand Response (DR) focuses on reducing or shifting building energy use during peak demand periods, when electricity grids are under the most stress.
During extreme weather conditions (very hot or very cold), energy demand spikes due to increased use of HVAC systems. Instead of building more power plants, utilities use demand response programs to balance supply and demand by encouraging buildings to temporarily reduce consumption.
๐ This is a shift from:
- Energy efficiency (using less energy overall)
โก๏ธ to - Energy flexibility (using energy at the right time)
๐น Intent
๐ To:
- Improve grid reliability
- Reduce peak demand
- Lower greenhouse gas emissions
- Encourage participation in demand response programs
๐น Core Concept
Demand Response is about WHEN you use energy, not just HOW MUCH
๐งฉ Compliance Paths (Cases)
๐ฅ Case 1: Demand Response Program Available
๐ Projects must:
- Enroll in a utility DR program
- Design systems for:
- Load shedding (reducing usage)
- Load shifting (rescheduling usage)
๐ฅ Case 2: No DR Program Available
๐ Projects must:
- Design building for future DR participation
- Include:
- DR-ready systems
- Communication-capable meters
- Load reduction plan
๐ Also:
- Coordinate with local utility (important for exam)
โ ๏ธ CRITICAL EXAM NOTE
๐ On-site renewable energy does NOT count
โ Solar panels โ Demand Response
โ
Adjusting energy use during peak = Demand Response
๐ Quick Summary Table
Aspect | Demand Response Credit |
Points | Up to 2 points |
Focus | Peak demand reduction |
Key Strategy | Load shedding / shifting |
Program Required? | Yes (if available) |
If not available | Design for future participation |
On-site renewables | โ Not acceptable |
System Requirement | DR-capable controls + communication |
๐ง Memory Tips (VERY IMPORTANT)
๐น Simple Way to Remember
๐ Efficiency = Use less energy
๐ Demand Response = Use energy at better times
๐น Two Key Words
๐ SHED + SHIFT
- Shed โ reduce load
- Shift โ move load
๐น Think Like the Grid
๐ Grid problem = peak demand
๐ Solution = buildings reduce usage temporarily
โ ๏ธ Common Exam Traps
โ โInstalling solar panels earns DR creditโ
๐ Incorrect
๐ Thatโs Renewable Energy credit, not DR
โ โDemand response reduces total annual energyโ
๐ Not necessarily
๐ It reduces peak demand, not total consumption
โ โDR only applies when program existsโ
๐ Incorrect
๐ Must design for future participation if not available
Final Takeaway
Demand Response is about grid interaction, not just building efficiency
LEED is rewarding buildings that behave like โsmart grid participantsโ
Official FAQs

A project installs solar panels but does not reduce peak demand. Does it earn this credit?
A building increases cooling setpoints during peak hours. Does this support demand response?
